Description
[0001] This application claims the benefit of and hereby
incorporates by reference U.S. Provisional Patent Application Ser.
No. 62/010,921, filed Jun. 11, 2014, with an attorney docket number
3712-049.PROV.
BACKGROUND
[0002] Portable electronic devices or electronic devices not near a
wired energy source typically receive energy from a portable energy
source, such as a battery. The portable energy source can enable a
user to operate the electronic devices without a wired connection
for an energy source. Portable energy sources, however, have a
limited amount of energy and require recharging as the electronic
device depletes energy from the portable energy source.
[0003] A common type of portable energy source is a rechargeable
battery. Traditionally, a rechargeable battery can be recharged by
physically coupling electrical contacts of a portable electronic
device or the rechargeable battery with an external energy source,
such as an energy unit connected to a wall energy outlet. More
recently, wireless charging has been developed to reduce the
inconvenience of having to physically connect a cable to charge the
rechargeable battery. In a wireless charging system, a wireless
transmitting coil coupled to an energy source, such as a wall
outlet, is used to induce a current in another wireless receiving
coil of the portable electronic device or battery.
[0004] A wireless charging system can provide wireless energy
between the transmitting coil and the receiving coil using an
unmodulated signal, which allows narrow tuning of the transmitting
coil and the receiver coil to a same frequency. However,
transferring energy using a narrowband signal can allow any
receiver, including unauthorized receivers, in the vicinity of the
transmitting coil to tune to the same frequency and receive
wireless energy. The unauthorized receivers can disrupt the
charging of authorized receivers. A need exists to efficiently and
safely transfer energy wirelessly to authorized users while
restricting access to unauthorized users.

the scope of the invention is thereby intended.
DETAILED DESCRIPTION
[0054] Before the present invention is disclosed and described, it
is to be understood that this invention is not limited to the
particular structures, process steps, or materials disclosed
herein, but is extended to equivalents thereof as would be
recognized by those ordinarily skilled in the relevant arts. It
should also be understood that terminology employed herein is used
for the purpose of describing particular examples only and is not
intended to be limiting. The same reference numerals in different
drawings represent the same element. Numbers provided in flow
charts and processes are provided for clarity in illustrating steps
and operations and do not necessarily indicate a particular order
or sequence.
[0055] The terms battery, cell, and/or battery cell as used herein
can be used interchangeably and can refer to any of a variety of
different cell chemistries and configurations. In one embodiment
the cell chemistries and configurations can include, but are not
limited to, lithium ion (e.g., lithium iron phosphate, lithium
cobalt oxide, other lithium metal oxides, etc.), lithium ion
polymer, nickel metal hydride, nickel cadmium, nickel hydrogen,
nickel zinc, silver zinc, or other battery type/configurations.
[0056] The term battery pack as used herein can refer to one or
more individual batteries contained within a single piece housing,
or a multiple piece housing. The one or more individual batteries
can be electrically interconnected in parallel and/or in series to
achieve a selected energy level (such as a voltage level or a
current level) and capacity level.
[0057] An increasing number and variety of electronic devices are
powered using non-wired energy sources, such as batteries or
wireless energy sources that provide power directly to the device
or to energy storage systems. The electronic devices can range from
mobile phones, portable music players, laptop computers, and tablet
computers to medical devices such as hearing aids, pace makers,
wheeled medical carts, medical measurement equipment, medical test
equipment, and other types of medical equipment.
[0058] Traditionally, battery chargers operate to charge one or
more batteries by either simultaneously charging one or more
batteries of the same type using a single charging port or by
charging each of the batteries of the same type simultaneously
using multiple charging ports. Traditional battery chargers can
only recharge one type of battery and do not account for individual
characteristics of different types of batteries. The battery
chargers are often limited in the type of battery they can
recharge. In one example, a traditional battery charger can only
provide a fixed voltage output and a fixed current output to a
selected battery or type of battery with a selected energy level.
Energy level in batteries are typically measured in watt-hours or
amp-hours.
[0059] Often, rechargeable batteries are used as a replenishable
energy source for electronic devices. In one embodiment, a battery
pack can include one or more rechargeable batteries. In one
example, the one or more rechargeable batteries can be a lead-based
battery, a lithium-based battery, a nickel based battery, or
another type of chemical storage battery.
[0060] Traditionally, a rechargeable battery pack provides energy
to an electronic device using physical electrically conductive
connections between the rechargeable battery pack and the
electronic device. When the traditional rechargeable batteries of
the rechargeable battery pack are depleted, the rechargeable
batteries can be replenished by connecting physical electrically
conductive contacts between the rechargeable battery pack and a
battery charger.
[0061] In one embodiment of the present invention, a wireless
transfer station can receive energy and/or send energy to another
device, such as another wireless transfer station, using a wireless
energy transfer scheme (e.g. transfer energy without wires). A
wireless energy transfer scheme can be any form of wireless energy
transfer associated with the use of electric fields, magnetic
fields, electromagnetic fields, and so forth that allows electrical
energy to be transmitted between two or more wireless transfer
elements without using physical electrical contacts. In one
example, a wireless energy transfer of wireless energy can be a
transfer of electrical energy from an energy source to an
electrical load without the use of interconnecting wires or
physical electrical contacts.
[0062] In one embodiment, the wireless transfer station can include
one or more wireless transfer coils to transfer energy and/or data
with other wireless transfer stations. The wireless transfer coil
can include one or more power management modules to control the
energy transfers and/or data transfers with the other wireless
transfer stations.
[0063] Examples of a wireless transfer station includes a wireless
energy rechargeable battery pack, a wireless energy transfer
platform and/or data transceiver integrated into a medical cart, a
wireless energy transfer platform and/or data transceiver
integrated into an electronic device, a wireless energy transfer
platform and/or data transceiver integrated into a piece of
furniture, a wireless energy transfer platform and/or data
transceiver integrated into a plate mounted to a wall, a wireless
energy transfer platform and/or data transceiver integrated into a
device (such as a medical device or medical equipment), and so
forth.
[0064] In one example, the wireless transfer station can be a
wireless energy battery pack that can be attached to a device, such
as a medical cart or medical equipment. The wireless transfer
station that transfers energy and/or data with the device can also
relay the energy and/or data with other devices and/or wireless
transfer stations. These examples are not intended to be limiting.
The wireless transfer station can be implemented in a variety of
electronic devices and mounting locations.
[0065] In one embodiment, the wireless transfer station can receive
data from and/or send data or information to another device, such
as another wireless transfer station, using a wireless data
transfer scheme. In another embodiment, the wireless data transfer
scheme can be any form of data transfer associated with a
communications network. In another embodiment, the communications
network can be a cellular network. The cellular network can be
configured to operate based on a cellular standard, such as the
third generation partnership projection (3GPP) long term evolution
(LTE) Rel. 8, 9, 10, 11, or 12 standard, or the institute of
electronic and electrical engineers (IEEE) 802.16p, 802.16n,
802.16m-2011, 802.16h-2010, 802.16j-2009, or 802.16-2009
standard.
[0066] In another embodiment, the communications network can be a
wireless local area network (such as a wireless fidelity network
(Wi-Fi)) that can be configured to operate using a standard such as
the IEEE 802.11-2012, IEEE 802.11ac, or IEEE 802.11ad standard. In
another embodiment, the communications network can be configured to
operate using a Bluetooth standard such as Bluetooth v1.0,
Bluetooth v2.0, Bluetooth v3.0, or Bluetooth v4.0. In another
embodiment, the communications network can be configured to operate
using a ZigBee standard, such as the IEEE 802.15.4-2003 (ZigBee
2003), IEEE 802.15.4-2006 (ZigBee 2006), or IEEE 802.15.4-2007
(ZigBee Pro) standard. In another embodiment, the wireless data
transfer scheme can be any form of data transfer associated with
electric fields, magnetic fields, or electromagnetic fields that is
transmitted between two or more wireless transfer elements without
using physical electrical contacts.
[0067] In one embodiment, the wireless transfer station can include
one or more wireless transfer elements. In one example, a wireless
transfer element can be a wireless transfer coil. In one
embodiment, the wireless transfer coil can be a coil used for
transmitting and/or receiving energy and/or data using magnetic
inductance and/or magnetic resonance.
[0068] FIG. 1 illustrates a wireless transfer station 110. FIG. 1
further illustrates that the wireless transfer station 110 can
include a wireless transfer coil 120 and a power management module
130. In one example, the power management module 130 can convert
energy received from an energy source, such as another wireless
transfer station or an alternating current (AC) energy outlet, a
selected current level, a selected voltage level, and/or a selected
wattage level. In another embodiment, the wireless transfer station
110 can include one or more batteries, such as rechargeable
batteries. In one embodiment, the wireless transfer coil 120 can
comprise a transmitting coil and/or a receiving coil.
[0069] FIG. 2 illustrates an example of transferring energy or data
between a plurality of wireless transfer coils 210 and 220. FIG. 2
further illustrates that one of the plurality of wireless transfer
coils 210 can be a transmitting coil 210 and another one of the
plurality of wireless transfer coils 220 can be a receiving coil
220. In one embodiment, energy and/or data can be transferred from
the transmitting coil 210 to the receiving coil 220 by coupling the
transmitting coil 210 with the receiving coil 220 to enable the
energy or data to be transferred over a gap or distance. In one
example, wireless energy can be transferred by generating a
magnetic field 230 (such as an electromagnetic field) at the
transmitting coil 210 and positioning the receiving coil 220 within
the magnetic field 230 to induce a current at the receiving coil
220. The process of inducing a current at the receiving coil is
referred to as coupling the receiving coil 220 to the transmitting
coil 210. In one embodiment, the wireless transfer coil coupling
for wireless energy or data transfer can be a magnetic induction
coupling. In another embodiment, the wireless transfer coil
coupling for wireless energy transfer can be a magnetic resonant
coupling.
[0070] In one embodiment, the transmitting coil 210 can be a
transmitting induction coil and the receiving coil 220 can be a
receiving induction coil. The wireless transfer station can use a
magnetic field to transfer energy between the transmitting coil 210
coupled to a first object (such as a wireless transfer station) and
a receiving coil 220 of a second object (such as another wireless
transfer station) without any direct contact between the
transmitting coil 210 and the receiving coil 220, e.g. inductive
coupling.
[0071] In one embodiment, inductive coupling can occur when the
transmitting coil 210 creates a magnetic field 230 (such as an
alternating electromagnetic field) using an energy source, such as
an alternating current (AC) energy outlet or a direct current (DC)
battery. A current can be induced at the receiving coil 220 using
the magnetic field when the receiving coil 220 is located within
the magnetic field 230.
[0072] In one example, when the transmitting coil 210 and the
receiving coil 220 are within a threshold proximity distance, the
transmitting coil 210 and the receiving coil 220 can couple to form
an electric transformer. In one embodiment, current from the
receiving coil 220 can be transferred to a battery or an electronic
device. In another embodiment, the current can be stored in one or
more energy sources of the wireless transfer station, such as a
battery. In another embodiment, the current can be transferred to a
device coupled to the wireless transfer station. In one embodiment,
an impedance of one or more transmitting coils 210 can be
substantially matched with an impedance of one or more receiving
coils 220.
[0073] In one embodiment, the transmitting coil 210 can be a
transmitting resonant coil and the receiving coil 220 can be a
receiving resonant coil. A wireless resonant transfer can be a
resonant transmission of energy or data between at least one
transmitting coil 210 and at least one receiving coil 220. In
another embodiment, at least one transmitting coil 210 and at least
one receiving coil 220 can be tuned to resonate at a same frequency
or a substantially same frequency.
[0074] In one example, resonant transmission of wireless energy can
occur when the transmitting coil and the receiving coil are
constructed to resonate at the same frequency or approximately the
same frequency. The transmitting coil 210 can be configured to
oscillate current at the resonant frequency of the coils to
transfer energy and/or data. The oscillating current of the
transmitting coil 210 can generate an oscillating magnetic field at
the selected resonant frequency of the receiving coil. When the
receiving coil 220 is positioned adjacent to the oscillating
magnetic field and constructed to operate at the same frequency or
substantially the same frequency as the transmitting coil 210, the
receiving coil 220 can receive energy and/or data from the
oscillating magnetic field.
[0075] In another embodiment, an impedance of one or more
transmitting coils 210 can be substantially matched with an
impedance of one or more receiving coils 220 for energy and/or data
transfer. In another embodiment, the transmitting coil and the
receiving coil can be positioned such that the receiving coil is
within the near field of the magnetic field of the transmitting
coil. The near field can be based within the Fraunhofer region,
which can be approximately within 1/2.pi. times the wavelength of
the electromagnetic field.
[0076] One advantage of placing the receiving coil within the near
field for wireless energy transfer is to reduce an amount of energy
that may be radiated or leaked from the wireless transfer coils 210
and 220, e.g. energy not received at the receiving coil 220. In one
embodiment, energy in a magnetic field falls off as the inverse
squared of a distance (1/d.sup.2) between the transmitting coil 210
and the receiving coil 220 within the near field. In one example,
magnetic resonant coupling can be used to transfer energy at
relatively high energy levels between the transmitting coil 210 and
the receiving coil 220 and to minimize or reduce energy leaking
away from the wireless transfer coils 210 and 220.
[0077] Another advantage of using a near field or a non-radiating
field for wireless energy transfer can be that the near field or
the non-radiating field can be used in areas adjacent to biological
material, such as humans or other biological entities, with minimal
or no effects to the biological material from the wireless energy
transfer. In another embodiment, a wireless transfer station, such
as in FIG. 1, can use a radio frequency (RF) signal, ultrasound,
and/or laser beams to wirelessly transfer energy and/or data
between a transmitting device and a receiving device.
[0078] FIG. 3a shows a wireless transfer station 310 that can
include: a wireless transfer coil 320, a power management module
330, and a conversion module 340. In one embodiment, the wireless
transfer coil 320 can be used for resonance coupling and/or
induction coupling. In one example, the conversion module 340 can
be coupled to the wireless transfer coil 320 and used to switch the
wireless transfer coil 320 from a resonance mode (i.e. transferring
wireless energy and/or data using magnetic resonance coupling) to
an induction mode (i.e. transferring wireless energy and/or data
using magnetic induction coupling), or vice versa.
[0079] In one embodiment, the wireless transfer coil 320 of the
wireless transfer station 310 can be used for transmitting wireless
energy and/or receiving wireless energy. In one example, the
conversion module 340 can be coupled to the wireless transfer coil
320 and used to switch the wireless transfer coil 320 from a
receiving mode (i.e. receiving wireless energy and/or data) to a
transmitting mode (i.e. transmitting wireless energy and/or data),
or vice versa.
[0080] In one embodiment, when the conversion module 340 of the
wireless transfer station 310 is in the transmitting mode, the
conversion module 340 or the power management module 330 can
convert energy received from an energy source (such as a power
outlet or a battery) at a selected voltage into a high frequency
alternating current and transmit the high frequency alternating
current to a wireless transfer coil of another wireless transfer
station. The high frequency alternating current can flow through
one or more loops of the wireless transfer coil 320 and create a
varying magnetic field that can induce a current in the other
wireless transfer coil. In another embodiment, when the conversion
module 340 is switched to the receiving mode, a varying magnetic
field from another wireless transfer station can induce an
alternating current flowing through the one or more loops of the
wireless transfer coil 320. The current flowing through the one or
more loops can be converted into a direct current (DC) by the
conversion module 340 or the power management module 330 and
directed to a battery coupled to the wireless transfer station 310
or a device that is electrically coupled to the wireless transfer
station 310.
[0081] In one embodiment, each wireless transfer coil 320 of a
wireless transfer station 310 can be coupled to a separate
conversion module 340. In another embodiment, one or more
conversion modules 340 can be coupled to one or more selected
groups of wireless transfer coils 320. One advantage of using a
conversion module 340 for switching a wireless transfer coil 320
between transmitting mode and receiving mode can be to reduce a
complexity of design and/or size of a wireless transfer station 310
by reducing a number of wireless transfer coils 320 used to
transmit and/or receive wireless energy. Another advantage of using
a conversion module 340 for switching a wireless transfer coil
between a transmitting mode and receiving mode is to provide a dual
functionality to a wireless transfer station of both transmitting
and receiving wireless energy.
[0082] FIG. 3b illustrates a wireless transfer station 350. FIG. 3b
further illustrates that the wireless transfer station 350 can
include: a wireless transfer coil 360; a power management module
370; and a battery 380. The battery 380 can comprise a plurality of
batteries, such as rechargeable batteries. In one example, the
power management module 370 can convert energy received using the
wireless transfer coil 360 from an energy source, such as another
wireless transfer station or an alternating current (AC) energy
outlet, to a selected current level at a selected voltage level to
provide a selected wattage level. In one embodiment, the power
management module can transfer the converted energy to the battery
380 to store the energy.
[0083] FIG. 3c shows a cross-sectional view of a battery 380, for
example a lithium ion battery utilizing an 18650 battery
form-factor. The battery 380 can include: a case 386, such as a
cylindrical case; one or more electrodes 388, and a cap 384. In one
embodiment, the case 386 can be made of a metal, such as
nickel-plated steel, that can be non-reactive with battery
materials, such as an electrolyte or the one or more electrodes
388. In one embodiment, a bottom surface 390 of the case 386 can be
seamlessly integrated with the remainder of the case 386. In one
embodiment, a top end 382 of the case 386 can be open ended. In
another embodiment, the cap 384 can be located at the top end 382
of the case 386. In another embodiment, the top end 382 can be a
positive electrical terminal of the battery 380 and the bottom end
390 can be a negative electrical terminal. In one example, the
positive electrical terminal and the negative electrical terminal
of the battery 380 can be connected to a wireless transfer station
to provide energy to the wireless transfer station. In another
embodiment, a plurality of batteries can be connected in series
and/or in parallel. In one embodiment, the battery 380 can be
connected to a power management module, such as the power
management modules in FIGS. 3a and 3b.
[0084] FIG. 4 shows a wireless transfer station 410 that can
include: a wireless transfer coil 420, a power management module
430, a communications module 440, and/or a coordination module 450.
In one embodiment, the wireless transfer station 410 can
communicate with one or more other wireless transfer stations or
one or more devices using the communication module 440.
[0085] In one embodiment, the communication module 440 of the
wireless transfer station 410 can use a communications network to
communicate the data to a device and/or another wireless transfer
station. In another embodiment, the communications network can be a
cellular network that may be a 3GPP LTE Rel. 8, 9, 10, 11, or 12 or
IEEE 802.16p, 802.16n, 802.16m-2011, 802.16h-2010, 802.16j-2009,
802.16-2009. In another embodiment, communications network can be a
wireless network (such as a wireless fidelity network (Wi-Fi)) that
may follow a standard such as the Institute of Electronics and
Electrical Engineers (IEEE) 802.11-2012, IEEE 802.11ac, or IEEE
802.11ad standard. In another embodiment, the communications
network can be a Bluetooth connection such as Bluetooth v1.0,
Bluetooth v2.0, Bluetooth v3.0, or Bluetooth v4.0. In another
embodiment, the communications network can be a ZigBee connection
such as IEEE 802.15.4-2003 (ZigBee 2003), IEEE 802.15.4-2006
(ZigBee 2006), IEEE 802.15.4-2007 (ZigBee Pro).
[0086] In one embodiment, the wireless transfer station 410 can
transfer energy to one or more other wireless transfer stations,
receive energy from one or more other wireless transfer stations,
and/or communicate data or information with one or more other
wireless transfer stations. In another embodiment, the coordination
module 450 of the wireless transfer station 410 can coordinate when
energy is transferred between wireless transfer stations and/or
when data is communicated between wireless transfer stations. In
another embodiment, the coordination module 450 can use the
communications module 440 to communicate with one or more other
wireless transfer stations to coordinate energy and/or data
transfer between the wireless transfer station 410 and the one or
more other wireless transfer stations.
[0087] One advantage of transferring energy and/or data using a
wireless transfer station 410 is to provide a single connection
point between the wireless transfer station 410 and other wireless
transfer stations and/or other devices. Another advantage of
transferring energy and/or data using the wireless transfer station
410 can be to enable a single step for both transferring energy
between the wireless transfer station 410 and other wireless
transfer stations and communicating or synchronizing data
communicated between the wireless transfer station 410 and other
wireless transfer stations. In one example, when a first wireless
transfer station (such as a wireless transfer station integrated
into a medical cart) is located adjacent to a second wireless
transfer station (such as a wireless transfer station integrated
into a plate mounted to a wall or a floor mat), the first wireless
transfer station can both receive energy from the second wireless
transfer station and synchronize information with the second
wireless transfer station.
[0088] In one embodiment, the coordination module 450 can
communicate with a conversion module, as in FIG. 3a, to coordinate
when one or more wireless transfer coils 420 of the wireless
transfer station 410 can transmit and/or receive wireless energy
and/or data. In one example, the coordination module 450
communicates with a conversion module, as in FIG. 3a, to coordinate
transmitting and/or receiving wireless energy and/or data by
coordinating when one or more wireless transfer coils 420 are in a
transmitting mode or a receiving mode, as discussed in the
preceding paragraphs.
[0089] FIG. 5a shows a wireless transfer station 510 that includes
one or more resonant wireless transfer coils 520 and/or one or more
induction wireless transfer coils 530. In one example, the wireless
transfer station 510 can have a resonant wireless transfer coil 520
and can transfer energy to a resonant wireless transfer coil of a
first wireless transfer station and can have an induction wireless
transfer coil 530 and can transfer energy to an induction wireless
transfer coil of a second wireless transfer station. One advantage
of the wireless transfer station having both resonant wireless
transfer coils 520 and induction wireless transfer coils 530 can be
to provide energy and/or data to wireless transfer stations and/or
devices with only one of the resonant wireless transfer coils or
the induction wireless transfer coils, thereby enabling more
devices to transfer energy to the wireless transfer station.
[0090] In one embodiment, a device or another wireless transfer
station can include one or more resonant wireless transfer coils
and/or one or more induction wireless transfer coils. In one
embodiment, the device or the other wireless transfer station
receiving energy from the wireless transfer station 510 can select
whether to receive wireless energy from the one or more resonant
wireless transfer coils 520 or the one or more induction wireless
transfer coils 530 of the wireless transfer station 510. In another
embodiment, the wireless transfer station 510 can be configured to
select whether to transmit wireless energy using the one or more
resonant wireless transfer coils 520 or the one or more induction
wireless transfer coils 530. In one example, a resonant
transmitting coil and a resonant receiving coil pair can have a
higher energy transfer efficiency than an induction transmitting
coil and an induction receiving coil pair. In this example, when
the device or the other wireless transfer station includes a
resonant receiving coil, the other wireless transfer station and/or
the device or the wireless transfer station 510 can be configured
to use one or more resonant wireless transfer coils to perform an
energy transfer.
[0091] In one embodiment, the one or more resonant wireless
transfer coils 520 and/or the one or more induction wireless
transfer coils 530 can be transmitting coils and/or receiving
coils. In another embodiment, the wireless transfer station 510 can
include one or more repeater coils 540. In one example, the
repeater coil 540 can enhance wirelessly transmitted energy of a
transmitting coil, e.g. providing additional transmission energy.
In another example, the repeater coil 540 can receive the wireless
energy from a transmitting coil and relay or retransmit the
received energy to another repeater coil 540 or to a receiving
coil. The repeater coils can be configured as inductive repeater
coils or resonant repeater coils, and associated with transmit
coils and receive coils of the same kind.
[0092] In one embodiment, the one or more resonant wireless
transfer coils 520, the one or more induction wireless transfer
coils 530, and/or the repeater coil 540 can include a power
management module 550 configured to covert energy from an energy
source to a varying magnetic field. In another embodiment, the one
or more resonant wireless transfer coils 520, the one or more
induction wireless transfer coils 530, and/or the repeater coil 540
can be coupled to a power management module 550 configured to
convert a magnetic field into energy, such as energy at a selected
current level, a voltage level, a wattage level, and/or an amperage
level, and transfer the energy to a battery of the wireless
transfer station 510 or a device coupled to the wireless transfer
station 510.
[0093] FIG. 5b illustrates one exemplary embodiment of the wireless
transfer station 510. In one embodiment, the wireless transfer
station 510 can be a stand-alone device used to transfer wireless
energy to other devices. In another embodiment, the wireless
transfer station 510 can include a wireless transfer coil 520 and a
power management module 530. In another embodiment, the wireless
transfer station 510 can direct energy received at the wireless
transfer coil 520 using the power management module 530 to a device
coupled to the wireless transfer station 510.
[0094] In another embodiment, the wireless transfer station 510 can
transfer the energy received at the wireless transfer coil 520 to
the coupled device using physical electrical contacts. In another
embodiment, the wireless transfer station 510 can transfer the
energy to the coupled device using the wireless transfer coil 520.
In one embodiment, the wireless transfer station 510 can store
received energy at a battery 540.
[0095] FIG. 5c illustrates one exemplary embodiment of the wireless
transfer station 510 integrated into an object 520. In one
embodiment, the object 520 that the wireless transfer station 510
can be integrated into can be an electronic device, such as a
medical device or a wireless energy battery pack. In one example,
the wireless transfer station 510 can be integrated into a medical
infusion pump and provide energy to the medical infusion pump. In
another embodiment, the object 520 can be integrated into a medical
cart (such as a work surface of the medical cart), a floor mat, a
floor surface, a plate mounted to a wall, a wall surface, chair
railing, a room railing, a ceiling tile, a ceiling surface, and so
forth. FIG. 5d illustrates that a plurality of wireless transfer
stations 510 can be integrated into an object 520. FIG. 5d is the
same as FIG. 5c in all other aspects.
[0096] FIG. 6 shows a wireless transfer station 610 that can
provide energy to one or more non-wire powered electronic devices
620 and/or one or more rechargeable batteries 640 coupled to a
device 630. In another embodiment, the wireless transfer station
610 can provide energy to different types of non-wire powered
electronic devices, such as a monitoring device, a computing
device, a medical device, and so forth. In one example, the
wireless transfer station 610 can provide a unified energy source
for the devices 620 and 630 and/or the one or more rechargeable
batteries 640 coupled to the device 630. In one embodiment, a
unified energy source can be a power source that can provide power
to a device, a wireless transfer station, and/or a battery without
using different power connectors to provide the power to the
device, the wireless transfer station, and/or the battery. In one
embodiment, the wireless transfer stations can include an
integrated wireless energy coil and a physical electrical energy
connection terminal. In another embodiment, the wireless transfer
station 610 can transfer energy via an electrical energy connection
terminal and/or an integrated wireless transfer coil.
[0097] FIG. 7a shows a device 710 with a wireless transfer station
720 coupled to the device 710 or integrated into the device 710. In
one embodiment, the wireless transfer station 720 can be configured
to provide energy to batteries 730 of the device 710 and the
batteries 730 can provide energy to the device 710. In another
embodiment, the wireless transfer station 720 can be configured to
provide energy directly to the device 710, e.g. without using
batteries. In one example, a power management module 740 can
provide energy directly to the device 710 by receiving energy at a
wireless transfer coil 750 of the wireless transfer station 710
from a wireless transfer coil of another wireless transfer station
and direct the energy via the power management module 740 to the
device 710 and/or the batteries 730.
[0098] FIG. 7b illustrates a wireless transfer station 710 with a
plurality of wireless transfer coils 730 configured to transfer
energy and/or data to an electronic device 720, such as a medical
device. The medical device can include one or more integrated
wireless transfer stations 740. In one embodiment, the electronic
device 720 can be located adjacent to the wireless transfer station
710. For example, a bottom surface of the electronic device 720 can
abut a top surface of the wireless transfer station 710.
[0099] In one embodiment, the wireless transfer station or one or
more components of the wireless transfer station can be
incorporated into a device. The device can be: a wheeled medical
cart; a platform coupled the wheeled medical cart; a platform
integrated into the wheeled medical cart; and/or a device coupled
the wheeled medical cart.
[0100] FIGS. 8a, 8b, and 8c show a wheeled medical cart 810 with
different configurations of integrated wireless transfer stations
820, 830, and 840, respectively. FIG. 8a shows a wheeled medical
cart 810 with a plurality of wireless transfer stations 820
integrated into a selected area 852 of a work surface 850 of the
wheeled medical cart 810. FIG. 8b shows a wheeled medical cart 810
with a plurality of wireless transfer stations 830 integrated into
a work surface 860 of the wheeled medical cart 810. The wheeled
medical cart 810 of FIG. 8b is the same as the wheeled medical cart
810 in FIG. 8a in all other regards. FIG. 8c shows a wheeled
medical cart 810 with one or more of wireless transfer stations 840
integrated into a device holder 870 of the wheeled medical cart
810. The wheeled medical cart 810 of FIG. 8c is the same as the
wheeled medical carts 810 in FIGS. 8a and 8b in all other
regards.
[0101] In one embodiment, the wheeled medical cart 810 can have one
or more attached work surfaces 850 or 860. In one example, the one
or more work surfaces 850 or 860 and/or device holder 870 of the
wheeled medical cart can include one or more integrated or coupled
wireless transfer coils, such as one or more transmitting coils,
one or more repeater coils, and/or one or more receiving coils. In
another embodiment, the one or more work surfaces 850 or 860 and/or
device holder 870 can have one or more selected areas for other
devices, such as medical devices and/or mobile devices, to be
placed on the one or more work surfaces 850 or 860 and/or device
holder 870 and receive wireless energy.
[0102] In one embodiment, the device holder 870 can be designed to
hold one or more devices at selected alignments to orient the one
or more devices to receive energy from one or more of wireless
transfer stations 840. In one example, the device holder 870 can be
integrated into the wheeled medical cart 810 and the device holder
870 can hold and orient one or more medical devices to receive
wireless energy using wireless transfer stations coupled to the
medical devices and/or wireless transfer stations integrated into

devices. In another embodiment, the one or more wireless transfer
stations 880 can receive wireless energy while attached to the
wheeled medical cart. In another embodiment, the one or more
wireless transfer stations 880 can be removed from the wheeled
medical cart and can be attached to another wireless transfer
station or be located adjacent to the wireless transfer station and
receive wireless energy.
[0104] FIG. 9 shows one exemplary embodiment of floor mat 910 with
one or more integrated wireless transfer stations 920. In one
embodiment, the integrated wireless transfer stations 920 can

[0105] In another embodiment, the one or more integrated wireless
transfer stations 920 can include one or more wireless transfer
coils to transfer energy from the wireless transfer station 920 to
another wireless transfer station. In one example, a wireless
transfer station coupled to a wheeled medical cart can be moved
into a location in proximity or adjacent to the wireless transfer
station integrated 920 into the floor mat 910 and receive energy
from the one or more wireless transfer stations 920 integrated into
the floor mat 910.
[0106] FIG. 10 shows one exemplary embodiment of a flooring surface
1010 with one or more integrated wireless transfer stations 1020.
In another embodiment, the one or more integrated wireless transfer
stations 1020 can include one or more wireless transfer coils. In
another embodiment, the flooring surface 1010 can be a flooring
tile with the one or more integrated wireless transfer stations
1020 integrated into the flooring tile. In another embodiment, the
one or more integrated wireless transfer stations 1020 can be
coupled to the flooring surface, such as attached to an outer
surface of a flooring tile.
[0107] FIG. 11 shows one exemplary embodiment of a plate 1110
mounted to a wall 1180 with one or more integrated wireless
transfer stations 1120. In another embodiment, the one or more
integrated wireless transfer stations 1120 can include one or more
wireless transfer coils 1160. In another embodiment, the plate 1110
can be integrated into the wall 1180. In another embodiment, the
one or more integrated wireless transfer stations 1120 can be
coupled to the wall 1180, such as attached to an inner surface of
the wall 1180. In another embodiment, a receptacle 1130 can be
attached to the plate 1110. In another embodiment, the receptacle
1130 can receive a device, such as a medical device, or another
wireless transfer station. In another embodiment, one or more
wireless transfer stations 1140 can be coupled to the receptacle
1130 and the one or more wireless transfer stations 1140 can be
used to transfer energy and/or data with the device or the other
wireless transfer station, such as by using a wireless transfer
coil 1150.
[0108] In another embodiment, a plate 1110 can be attached to a
mounting plate 1170 that is attached to the wall 1180. One
advantage of attaching the plate 1110 to the mounting plate 1190
can be that the plate 1110 can be easily and/or quickly removed
from the mounting plate 1170 for maintenance, upgrades,
replacement, and so forth. In one embodiment, the plate 1110 can be
attached to the mounting plate 1170 using one or more fasteners or
connectors, such as hooks, quick connectors, screws, bolts, and so
forth.
[0109] In one embodiment, the wireless transfer station can monitor
an amount of energy and/or data transmitted by a wireless transfer
coil and/or an amount of energy and/or data received by the
wireless transfer coil. In one example, a first wireless transfer
station with a receiving coil can communicate energy information to
a second wireless transfer station with a transmitting coil, using
a communications module as discussed in the preceding paragraphs.
The energy information can include: voltage level information,
current draw level information, energy level information of the
energy received at the receiving coil, energy level information of
the energy transmitted from the transmitting coil, internal
temperature information, ambient temperature information, or other
types of desired metrics.
[0110] In one embodiment, the wireless transfer station can adjust
an amount of energy transmitted from a wireless transfer coil of a
wireless transfer station to another wireless transfer coil of
another wireless transfer station based on the energy information.
In one example, if a device with an integrated or coupled wireless
transfer station requires 5 volts (V) and 2 amps (A) of energy and
is currently receiving a voltage level or an amperage level at a
level above or below a selected energy level range (such as a
voltage range and/or a current range), the device or the coupled
wireless transfer station can communicate the energy information to
the wireless transfer station. In this example, the wireless
transfer station can adjust the energy transferred from the
wireless transfer coil to the other wireless transfer coil to bring
the energy level range received at a wireless transfer coil to a
level within a selected energy level range.
[0111] In another embodiment, a wireless transfer station can be a
communication hub between multiple devices and/or other wireless
transfer stations. In one example, the wireless transfer station
can be integrated into a medical cart. The medical cart can receive
data from a first device using a communication module (as discussed
in the preceding paragraphs) and relay the data to another wireless
transfer station, such as a wireless transfer station attached to a
wall or floor.
[0112] In one embodiment, the wireless transfer station can
regulate an amount of energy received by one or more other wireless
transfer stations. In one example, when a first wireless transfer
station uses a transmitting coil for a transfer of energy and/or
data, the first wireless transfer station can control an amount of
energy received at a second wireless transfer station by detuning a
frequency of the transmitting coil by a selected amount. In another
example, when a first wireless transfer station uses receiving
coils for a transfer of energy and/or data, the first wireless
transfer station can control an amount of energy received from a
second wireless transfer station by detuning a frequency of the
receiving coil by selected amount. In another example, to regulate
the amount of energy and/or transferred between the first wireless
transfer station and the second wireless transfer station, the
first wireless transfer station and/or the second wireless transfer
station can adjust a number of winds of a wireless transfer coil
used to create an magnetic field or couple with the magnetic
field.
[0113] FIG. 12 illustrates a wireless transfer station transferring
energy and/or data to a plurality of different devices and other

the wireless transfer station 1230, and/or the selected group of
other wireless transfer stations 1240 can be tuned to different
frequencies 1250, 1260, and 1270, respectively. In one embodiment,
the wireless transfer station 1210 can switch a plurality of
wireless transfer coils of the wireless transfer station 1210 to
the frequencies 1250, 1260, and 1270 that correspond to the
frequencies for the device 1220, the wireless transfer station
1230, and/or the selected group of other wireless transfer stations
1240, respectively, to provide data and/or selected amounts of
energy on the frequencies 1250, 1260, and 1270. In one embodiment,
the different frequencies 1250, 1260, and 1270 can be different
resonant frequencies. In one embodiment, the wireless transfer
station 1210 can switch one wireless transfer coil of the wireless
transfer station 1210 to different frequencies 1250, 1260, and 1270
that correspond to the frequencies for the device 1220, the
wireless transfer station 1230, and/or the selected group of other
wireless transfer stations 1240, respectively to provide data
and/or selected amounts of energy on the frequencies 1250, 1260,
and 1270 for selected periods of time. In one embodiment, a
frequency of the wireless transfer coils of the wireless transfer
station 1210, the device 1220, the wireless transfer station 1230,
and/or the selected group of other wireless transfer stations 1240
can be dynamically adjusted or varied to different selected
frequencies. In another embodiment, different amounts of energy
and/or data can be transferred on the different frequencies 1250,
1260, and/or 1270. In another embodiment, an amount of energy
and/or data transferred on the different frequencies 1250, 1260,
and 1270 can be dynamically varied.
[0114] In one embodiment, the wireless transfer station 1210 can
collect and/or store data and/or energy information of the wireless
transfer station 1210, the device 1220, the wireless transfer
station 1230, and/or the selected group of other wireless transfer
stations 1240. In another embodiment, the wireless transfer station
1210 can analyze the data and/or energy information to determine an
amount of energy received and/or used by the wireless transfer
station 1210, the device 1220, the wireless transfer station 1230,
and/or the selected group of other wireless transfer stations 1240.
In another embodiment, the wireless transfer station 1210, the
device 1220, the wireless transfer station 1230, and/or the
selected group of other wireless transfer stations 1240 can collect
and/or store the data and/or energy information.
[0115] In one embodiment, the energy information can include: a
state of the device 1220, the wireless transfer station 1210 or
1230, and/or the selected group of other wireless transfer stations
1240; a state of a subsystem or module of the device 1220, the
wireless transfer station 1210 or 1230, and/or the selected group
of other wireless transfer stations 1240; a state of the device
1220, the wireless transfer station 1230, and/or the selected group
of other wireless transfer stations 1240 within a coverage area of
the wireless transfer station 1210; location information of the
device 1220, the wireless transfer station 1230, and/or the
selected group of other wireless transfer stations 1240 within the
coverage area of the wireless transfer station 1210; a wireless
transfer station identification (ID), a device ID, a wireless
transfer station subsystem ID or module ID, a usage level of the
device 1220, the wireless transfer station 1210 or 1230, and/or the
selected group of other wireless transfer stations 1240; and/or
health information of the device 1220, the wireless transfer
station 1230, and/or the selected group of other wireless transfer
stations 1240 within the coverage area of the wireless transfer
station 1210. In one embodiment, the health information can be
information of an actual full charge capacity of one or more
batteries or one or more battery cells of the device 1220, the
wireless transfer station 1210 or 1230, and/or the selected group
of other wireless transfer stations 1240 compared to a designed
capacity of one or more batteries or one or more battery cells of
the device 1220, the wireless transfer station 1210 or 1230, and/or
the selected group of other wireless transfer stations 1240. In one
example, the actual full charge capacity of a battery of the
wireless transfer station 1210 can be 16 amp hours and the designed
capacity of the battery can be 24 amp hours and the health
information can indicate that the actual full charge capacity is
below the designed capacity. In another embodiment, the health
information can include a battery depletion rate, a number of
charge cycles of a battery or group of batteries, an amount of
charge a battery or group of batteries received for a charge
period, an average charge period for a battery or group of
batteries, a remaining battery capacity level of a battery or group
of batteries, and so forth.
[0116] In one embodiment, selected locations can have wireless
transfer stations that can provide energy to one or more devices
and/or other wireless transfer stations. The wireless transfer
stations can determine an ID of the one or more devices or the
other wireless transfer stations and indicate the location of the
devices and/or the other wireless transfer stations. In one
example, a wheeled medical cart can receive energy from a wireless
transfer station at a patient room in a hospital. The wireless
transfer station can provide location information of the location
of the wheeled medical cart to a central server of the hospital or
information technology (IT) department indicating the location of
the wheeled medical cart.
[0117] In one embodiment, wireless energy and/or data transferred
between a first wireless transfer station and a second wireless
transfer station can be an alternating current (AC) energy signal.
In another embodiment, the first wireless transfer station can send
the AC energy signal and to the second wireless transfer station,
and the second wireless transfer station can change the AC energy
signal into a direct current (DC) energy signal. In one example,
the second wireless transfer station can be a wireless energy
battery pack. In this example, the wireless energy battery pack can
include a built-in charger to convert the AC energy signal to a DC
energy signal and transfer the DC energy to one or more batteries
or battery cells of the wireless energy battery pack.
[0118] FIG. 13 depicts a wireless transfer station 1310 operable to
adjust transferred energy. In one embodiment, the wireless transfer
station 1310 can include a wave rectifier 1320 to adjust (e.g. step
up or step down) a voltage level of transferred energy. In another
embodiment, the wireless transfer station 1310 can include a buck
converter 1330 and the wave rectifier 1320 can transfer the
wireless energy to one or more batteries or one or more battery
cells 1360 via the buck converter 1330. In another embodiment, a
current level of the wireless transfer station 1310 can be
controlled using a voltage stepper 1340 for voltage stepping. In
another embodiment, the wireless transfer station 1310 can use a
sensor resistor 1350 to measure the current going into the one or
more batteries or one or more battery cells 1360. In one example,
the wireless transfer station 1310 can communicate voltage level
information and/or current level information using a communication
module 1370. In this example, the wireless transfer station 1310
can adjust the voltage level and/or current level of the wirelessly
transferred energy to a selected level based on the communicated
voltage level information and/or current level information. In
another embodiment, the wireless transfer station 1310 can use a
shunt or voltage stepper 1340 to control an amount of energy
transferred between the wireless transfer station 1310 and another
wireless transfer station.
[0119] In one embodiment, the wireless transfer station can
regulate an amount of energy received by one or more other wireless
transfer stations. In one example, when a first wireless transfer
station uses a wireless transfer coil to transfer energy, the first
wireless transfer station can control the amount of energy received
at a second wireless transfer station by detuning a frequency of
the wireless transfer coil of the first wireless transfer station
by a selected amount. In another example, the first wireless
transfer station can control the amount of energy received from the
second wireless transfer station by detuning a frequency of the
wireless transfer coil of the first wireless transfer station by
selected amount.
[0120] FIG. 14 shows a wireless transfer coil 1410 with a plurality
of loops or winds 1420. In one embodiment, an amount of energy
transmitted and/or received by the wireless transfer coil 1410 can
be adjusted using one or more adjustment modules 1430. In one
embodiment, the one or more adjustment modules 1430 can engage or
disengage one or more of the plurality of loops 1420 to:
effectively vary a size of the wireless transfer coil 1410; change
a number of active loops of the wireless transfer coil 1410; change
a shape of a magnetic field of the wireless transfer coil 1410;
change an amount of energy transferred using the wireless transfer
coil 1410; or enable or disable selected devices from receiving
energy and/or data from the wireless transfer coil 1410.
[0121] In one embodiment, the one or more adjustment modules 1430
can be one or more switches, such as an impedance matching switch
or an on/off switch. In one example, a selected number of the
plurality of loops 1420 can be engaged by turning on one or more of
the corresponding switches and a selected number of the plurality
of loops 1420 can be disengaged by turning off one or more of the
corresponding switches.
[0122] In one embodiment, a resonant frequency between of the
wireless transfer coil 1410 can be dynamically adjusted using the
one or more adjustment modules 1430. In one embodiment, the one or
more adjustment modules 1430 can be adjustable energy oscillators.
In another embodiment, the one or more adjustment modules 1430 can
be variable capacitors, variable inductors, and/or variable
inductors and the respective capacitance, resistance, and/or
inductance can be changed to tune or detune the wireless transfer
coil 1410.
[0123] In one embodiment, a wireless transfer coil of a first
wireless transfer station can have a fixed impedance and/or
resonant frequency and an impedance and/or resonant frequency of a
second wireless transfer coil of a second wireless transfer station
can be adjustable. In another embodiment, the impedance and/or
resonant frequency of the wireless transfer coil of the first
wireless transfer station and the impedance and/or resonant
frequency of the wireless transfer coil of the second wireless
transfer station can each be adjustable.
[0124] In one embodiment, each wireless transfer station can have a
unique station ID associated with the wireless transfer station. In
another embodiment, each station ID can be used to associate
selected information with each wireless transfer station. In
another embodiment, each wireless transfer station and/or each type
of wireless transfer station can be configured to have a plurality
of different characteristics, such as different form factors,
different voltage inputs and/or outputs, different current inputs
and/or outputs, and so forth.
[0125] In one embodiment, each rechargeable battery or battery cell
in a wireless transfer station can have a different battery ID. In
another embodiment, one or more types of rechargeable batteries or
battery cells in a wireless transfer station can each have
different battery IDs. In another embodiment, a wireless transfer
station can be coupled to a plurality of different types of devices
and/or other wireless transfer stations. In one example, the
different types of devices and/or other wireless transfer stations
can include: devices and/or other wireless transfer stations used
for selected applications, devices and/or other wireless transfer
stations with different voltage inputs or outputs, devices and/or
other wireless transfer stations with different current inputs or
outputs, and so forth. In another embodiment, the different types
of devices can use different types of wireless transfer stations.
In another embodiment, different station IDs for different wireless
transfer stations can be associated with selected types of devices.
In one example, each device and/or wireless transfer station can
determine when a wireless transfer station coupled to the device is
a wireless transfer station that is compatible with the device
using the station ID of the wireless transfer station and/or the
device ID of the device. In one embodiment, a device ID, a station
ID, and/or a battery ID can include: serial number information of
the device, the station, or the battery; a manufacturing date of
the device, the station, or the battery; a manufacturing location
of the device, the station, or the battery; and/or a version number
of the device, battery, or wireless transfer station,
respectively.
[0126] Traditionally, energy sources such as battery packs have
different energy connectors for coupling the battery packs to
different devices. Additionally, traditional battery packs have
different energy connectors for different energy transfer levels.
In one example, a battery coupled to a wheeled medical cart has one
energy connector for transferring energy to the wheeled medical
cart and a battery coupled to a medical fusion pump has a different
energy connector for transferring energy to the medical fusion
pump. Additionally, traditional battery packs for each type of
device have different energy transfer levels corresponding to the
device receiving the energy and require different battery pack
configurations for each type of device. In one example, a wheeled
medical cart may use a battery configured to transfer 20 volts and
5 amps of energy while a medical fusion pump may use a battery
configured to transfer 10 volts and 3 amps. In one embodiment, a
wireless transfer station can select the amount of energy, such as
a voltage level or a current level, to wirelessly transfer to a
device or other wireless transfer station based on a power
configuration, such as a voltage or a current input requirement, of
the device or other wireless transfer station. In one embodiment,
the wireless transfer station can adjust or change an amount of
energy transferred from the wireless transfer station to the device
or other wireless transfer station by selecting different sizes of
coils and/or tuning or detuning of coils (as discussed in the
preceding paragraphs). In one example, the wireless transfer
station can select a wireless transfer coil size or frequency to
transfer 5 volts of energy to a 5-volt device and select a
different wireless transfer coil size or frequency to transfer 10
volts of energy to a 10-volt device.
[0127] In one embodiment, the wireless transfer station can
communicate with a device or another wireless transfer station and
receive an energy requirement information of the device or the
other wireless transfer station. The wireless energy battery pack
can use the energy requirement information to determine the amount
of energy to transfer to the device or the other wireless transfer
station. In another embodiment, the wireless transfer station can
receive a device ID or a station ID from the device or the other
wireless transfer station, respectively, receiving energy from the
wireless transfer station. The device ID or station ID can be
associated with an energy requirement of the device or the other
wireless transfer station and the wireless transfer station can
adjust an energy level transfer based on the associated energy
requirement.
[0128] One advantage of the wireless transfer station selecting the
amount of energy to wirelessly transfer to a device or other
wireless transfer station is that the wireless transfer station can
be used with a plurality of different devices and/or other wireless
transfer stations with different energy requirements. Another
advantage of wireless transfer station having an adjustable energy
level transfer capability can be to enable the wireless transfer
station to be used with different devices and/or other wireless
transfer stations with different energy level requirements without
needing different energy connection adapters. In one example, the
wireless transfer station can be connected to the wheeled medical
cart, determine that the wheeled medical cart requires 20 volts and
5 amps of energy, and transfer the required energy. The wireless
transfer station can later be swapped to a medical fusion pump, the
wireless transfer station can determine the medical fusion pump
requires 10 volts and 3 amps, and transfer the required energy.
[0129] FIGS. 15a, 15b, and 15c provide examples of wireless
transfer coils in overlapping patterns. FIG. 15a shows a wireless
transfer coil 1530 with overlapping wireless transfer coils 1510
and 1520. FIG. 15a further shows wireless transfer coil 1520
overlapping wireless transfer coil 1510. FIG. 15b shows layers of
wireless transfer coils 1540, 1550, and 1560. FIG. 15b further
shows one exemplary embodiment of layers of wireless transfer coils
with a bottom layer of wireless transfer coils 1560, a middle layer
of wireless transfer coils 1550, and a top layer of wireless
transfer coils 1540. FIG. 15c shows a show a wireless transfer
station 1570 with overlapping wireless transfer coil arrays 1580
and 1590, as further discussed in the proceeding paragraphs. One
advantage of overlapping the wireless transfer coils can be to
shape an overall magnetic field from a plurality of wireless
transfer coils.
[0130] In one embodiment, to increase a coupling distance range
between a transmitting coil and a receiving coil and/or to increase
a range of alignment positions between a transmitting coil and a
receiving coil, a transmitting coil array and/or a receiving coil
array can be used. FIG. 16 show a wireless transfer station 1610
with an array of wireless transfer coils 1620. In one embodiment,
the wireless transfer coils of the array 1620 can be arranged in a
selected pattern, i.e. a coil array pattern. In one example, the
wireless transfer coils of the array 1620 can be arranged in a
rectangular pattern (such as in FIG. 16), a circular pattern, an
elliptical pattern, and so forth. FIG. 16 shows a wireless transfer
station 1610 with a non-overlapping wireless transfer coil array
pattern. In one embodiment, the wireless transfer coil array can
include an array of transmitting coils, receiving coils, repeater
coils, or a combination thereof. One advantage of non-overlapping
wireless energy coils can be to create separate electromagnetic
fields.
[0131] In one embodiment, the wireless transfer station can select
a number of wireless transfer coils in the coil array, e.g. a
wireless transfer coil array subset, to provide energy for wireless
energy transfer. FIG. 16 further shows the wireless transfer
station 1610 with wireless transfer coil subsets 1630 and 1640
within the wireless coil array 1620. In one embodiment, the
wireless transfer station 1610 can select a number of wireless
transfer coils, e.g. a wireless transfer coil subset. In one
example, the wireless transfer station 1610 can receive or transmit
energy using one or more wireless transfer coil subsets 1630 and
1640 within the wireless coil array 1620 and not receive or
transmit energy using the other wireless transfer coils in the
wireless coil array 1620. FIG. 16 shows a wireless transfer coil
subset 1630 with four selected wireless transfer coils in the
wireless transfer coil subset 1630 and wireless transfer coil
subset 1640 with two selected wireless transfer coils in the
wireless transfer coil subset 1640. Subsets 1630 and 1640 are
exemplary embodiments of different numbers of selected wireless
transfer coils in a wireless transfer coil subsets. The number of
selected wireless transfer coils in a wireless transfer coil subset
is not limited to the number of coils in subsets 1630 and 1640 of
FIG. 16.
[0132] In another embodiment, the wireless transfer station 1610
can detect a location of one or more receiving coils relative to
one or more transmitting coils in the wireless coil array 1620.
When the location of the one or more receiving coils is determined
relative to the one or more transmitting coils, the wireless coil
array 1620 array provide can energy to the one or more wireless
transfer coils or a wireless transfer coil array subset, such as
wireless transfer coil subset 1630 or 1640, corresponding to the
location of the one or more receiving coils. One advantage of
providing power to the one or more the one or more wireless
transfer coils or the wireless transfer coil array subset
corresponding to the location of the one or more receiving coils
can be to increase or optimize an amount of energy received at the
one or more receiving coils.
[0133] In one embodiment, to detect the location of the one or more
receiving coils of a device or another wireless transfer station
relative to one or more transmitting coils of the wireless transfer
station 1610, the wireless transfer station 1610 can be in
communication with the device or the other wireless transfer
station. In one example, the other wireless transfer station can
send a beacon to the wireless transfer station 1610 indicating a
location of the other wireless transfer station or one or more
receiving coil of the other wireless transfer station relative to
the one or more wireless transfer coils or the wireless transfer
coil array subset. In another embodiment, the wireless transfer
station 1610 can determine alignment information based on the
beacon and indicate to a user alignment directions.
[0134] In one embodiment, to determine a number of transmitting
coils in the array subset 1630 or 1640 to provide energy to, the
wireless transfer station 1610 can serially or sequentially
applying energy to one or more wireless transfer coils in the
wireless coil array 1620. Another wireless transfer station with
one or more receiving coils can communicate energy information to
the wireless transfer station 1610 when different transmitting
coils are active and transferring energy. The wireless transfer
station 1610 can use the energy information to determine an optimal
number and/or subset of the transmitting coils to provide energy to
for optimal or increased energy transfer to the receiving coil of
the other wireless transfer station.
[0135] In another embodiment, the wireless coil array 1620 can be
an array of receiving coils. The wireless coil array 1620 can
sequentially or serially connect a selected subset of receiving
coils to a receiving energy source and determine an arrangement of
a selected subset of receiving coils, such as subsets 1630 or 1640,
to receive an increased or optimal amount of energy from one or
more transmitting coils. In one embodiment, an energy management
system can determine an optimal number of selected transmitting
coils or selected receiving coils to activate for coupling or
pairing to provide a device or a wireless transfer station with a
selected level of energy.
[0136] In one embodiment, a wireless transfer station can use a
location of a transmitting coil and/or the location of a receiving
coil to determine alignment information, such as the alignment of a
receiving coil relative to a transmitting coil. In one example, the
wireless transfer station can use the alignment information to
determine a direction to move a transmitting coil and/or a
receiving coil to increase or optimize the energy received at the
receiving coil from the transmitting coil. In one example, when a
receiving coil of a device is located left of center of a
transmitting coil of a wireless transfer station, the wireless
transfer station or the device can determine that to increase the
energy transfer to the receiving coil, the receiving coil can be
moved to the right and/or the transmitting coil can be moved to the
left.
[0137] In one embodiment, the wireless transfer station can
indicate to a user of a device and/or another wireless transfer
station with the a wireless transfer coil the direction to move the
wireless transfer coil to increase an alignment and/or energy
transfer between a wireless transfer coil of the wireless transfer
station and the wireless transfer coil of the device or the other
wireless transfer station. In one embodiment, the wireless transfer
station can determine the direction to move a wireless transfer
coil by monitoring an energy level received at the wireless
transfer coil of the wireless transfer station. In one example, if
a receiving coil of a wireless transfer station is moved to the
left and an energy received from a transmitting coil of another
wireless transfer station decreases, the wireless transfer station
can determine that the receiving coil can be moved to the right
relative to the transmitting coil of the other wireless transfer
station to increase the received energy.
[0138] In one embodiment, the wireless transfer station can
determine a direction for a wireless transfer coil to move by
monitoring an energy load on one or more wireless transfer coils,
such as transmitting coils, of the wireless transfer station. In
one example, when a transmitting coil is moved to the left and an
energy load on the transmitting coil decreases, the wireless
transfer station can determine that the transmitting coil can be
moved to the right to increase the energy received at a receiving
coil of another wireless transfer station. In another embodiment, a
device and/or the other wireless transfer station can communicate
energy information to the wireless transfer station. The wireless
transfer station can use the energy information to determine the
location of a wireless transfer coil of the wireless transfer
station relative to a wireless transfer coil of the other wireless
transfer station and provide alignment information to the user.
[0139] In one embodiment, a wireless transfer station can include a
display or other sensory indicator for providing alignment
directions to a user via a graphical user interface. In another
example, the wireless transfer station can communicate the
alignment directions to another device with a display or other
sensory indicator for providing the alignment directions to the
user.
[0140] In one embodiment, a wireless transfer station can be a
wireless transfer hub (e.g. energy and/or data transfer) for a
plurality of selected devices and/or other wireless transfer
stations. FIG. 17 illustrates a wireless transfer hub 1710
transferring energy and/or information with an electronic device
1720, such as a medical device, and/or another wireless transfer
station 1730 using wireless transfer coils 1740. In one embodiment,
the electronic device 1720 and the other wireless transfer station
1730 can exchange energy and/or information with the wireless
transfer station 1710 at the same time or at different times. In
another embodiment, the electronic device 1720 and the other
wireless transfer station 1730 can transfer energy and/or
information with the wireless transfer hub 1710 using different
wireless transfer coils 1740.
[0141] In one example, the wireless transfer hub 1710 coupled to a
medical cart can wirelessly provide selected levels of energy to
systems and subsystems of the medical cart and/or other devices
coupled to the medical cart. In one embodiment, the wireless
transfer hub 1710 coupled to the medical cart can receive energy
and/or data from a wireless transfer station and relay the energy
and/or data to systems and subsystems of the medical cart and/or
other devices using one or more repeater coils.
[0142] In one embodiment, a medical cart or a device can have an
integrated wireless transfer station to provide energy to systems
and/or subsystems of the medical cart or the device when one or
more external wireless transfer stations (e.g. non-integrated
wireless transfer stations) are being recharged. In one embodiment,
the integrated wireless transfer station can include one or more
wireless transfer coils to receive energy and/or data from another
wireless transfer station. In one example, the medical cart or the
device can receive energy from the one or more external wireless
transfer stations until an energy level of the one or more external
wireless transfer stations is depleted or decreases below a
threshold energy level. In this example, when the energy level of
the one or more external wireless transfer stations is depleted or
decreases below a threshold energy level, the medical cart or the
device can be positioned adjacent a transmitter coil of another
wireless transfer station and the one or more external wireless
transfer stations can receive energy for recharging. In one
embodiment, while the one or more external wireless transfer
stations receive energy for recharging, the integrated wireless
transfer station can provide energy to the medical cart or the
device.
[0143] In one embodiment, the integrated wireless transfer station
can receive energy from the other wireless transfer station to
recharge one or more batteries of the integrated wireless transfer
station. In another embodiment, the integrated wireless transfer
station can receive energy from the one or more external wireless
transfer stations to recharge the one or more batteries of the
integrated wireless transfer station. In another embodiment, when
the one or more external wireless transfer stations receive energy
from another wireless transfer station, the one or more external
wireless transfer stations can provide partial or full energy to
the medical cart or the device.
[0144] In one embodiment, when the energy level of the one or more
external wireless transfer stations is depleted or decreases below
a threshold energy level, the one or more external wireless
transfer stations can be removed from the medical cart or the
device and placed adjacent a transmitter coil of another wireless
transfer station to receive energy to recharge the external
wireless transfer station. In one embodiment, while the one or more
external wireless transfer stations are removed for recharging
and/or until one or more other external wireless transfer stations
are attached to the medical cart or the device, the integrated
wireless transfer station can provide energy to one or more system
or subsystem of the medical cart or the device. In one embodiment,
when the medical cart or the device is placed adjacent to a
transmitter coil of a wireless transfer station, the integrated
wireless transfer station can receive energy from the wireless
transfer station to recharge the integrated wireless transfer
station.
[0145] In one embodiment, the medical cart or a device can include
a wireless transfer coil to transfer energy and/or data with
another wireless transfer station. In one example, the medical cart
or a device can use the wireless transfer coil to receive energy
and provide energy directly to one or more systems and/or
subsystems of the medical cart or the device and/or provide energy
to an energy source, such as a battery, of the medical cart or the
device. In one example, the medical cart or the device with the
wireless transfer coil can be placed near a transmitter coil of a
wireless transfer station and the wireless transfer coil can relay
energy to one or more systems and/or subsystems of the medical cart
or the device.
[0146] FIG. 18 shows a wireless transfer station A in communication
with wireless transfer station B to determine when to transfer
wireless energy and/or data between wireless transfer station A and
wireless transfer station B. In one embodiment, wireless transfer
station A can send a transfer request message to a wireless
transfer station B, as in block 1810. In one embodiment, the
transfer request message can include a frequency capability of the
wireless transfer station A. The transfer request message can also
include additional information, such as the voltage and current
level at which the energy is desired to be transferred, a charge
level of a battery, and an amount of time until a battery is full
and the energy is to be turned off. In another embodiment, the
wireless transfer station B can send a transfer approval message
with a frequency for transferring energy and/or data to the
wireless transfer station A, as in block 1820. In the transfer
approval message, the wireless transfer station B can send an
acknowledgment of the messages received, and actions to be taken,
such as changing the frequency, voltage, or current. In another
embodiment, the wireless transfer station A and the wireless
transfer station B can transfer energy and/or data between wireless
transfer station A and wireless transfer station B using the
frequency, voltage, current, and time indicated in the transfer
approval message, as in block 1830.
[0147] FIG. 19 shows a wireless transfer station A in communication
with a plurality of wireless transfer stations (e.g. wireless
transfer station B, wireless transfer station C, and wireless
transfer station D) to determine when to transfer wireless energy
and/or data between wireless transfer station A and one or more of
the plurality of wireless transfer stations. In one embodiment, the
wireless transfer station A can broadcast or unicast to the
wireless transfer station B, the wireless transfer station C,
and/or the wireless transfer station D a frequency message that
includes one or more frequencies to the wireless transfer station
B, the wireless transfer station C, and/or the wireless transfer
station D to use to receive energy and/or data, as in block 1910.
In one embodiment, when the wireless transfer station B, the
wireless transfer station C, and/or the wireless transfer station D
receive the frequency message, each of the wireless transfer
stations B, C, and/or D can adjust a frequency of a wireless
transfer coil coupled each of the wireless transfer stations B, C,
and/or D for transferring energy and/or data, as in blocks 1920,
1930, and 1940. In another embodiment, the wireless transfer
stations A, B, C, and/or D can dynamically adjust the frequency for
transferring energy and/or data using an active crystal array to
produce different frequency signals. In another embodiment, the
wireless transfer station A and the wireless transfer station B,
the wireless transfer station C, and/or the wireless transfer
station D can transfer energy and/or data between the wireless
transfer station A and the wireless transfer station B, the
wireless transfer station C, and/or the wireless transfer station D
using the one or more frequencies in the frequency message, as in
block 1950.
[0148] FIG. 20 shows a wireless transfer station 2010 that can
include: a wireless transfer coil 2020, a power management module
2030, and an interference-detecting module 2040. In one embodiment,
the interference-detecting module 2040 can determine that the
wireless transfer station 2010 is causing interference with a
communications device. In another embodiment, the
interference-detecting module 2040 can determine when the device or
an object is interfering with a wireless transfer of energy or data
between the wireless transfer station 2010 and another wireless
transfer station or device. In one example, when the interference
detecting module 2040 detects interference with the transfer of
energy or data, the wireless transfer station 2010 can increase or
decrease an energy and/or data transmission level of the wireless
transfer station 2010, increase or decrease an energy transfer
coverage scope of the wireless transfer station 2010, redirect
transmitted energy to another location, switch to using one or more
other wireless transfer coils for energy and/or data transfers,
temporarily stop transferring energy and/or data, communicate or
display an interference indicator to a user, and so forth.
[0149] In one example, a first wireless transfer station can
transfer energy and/or data on a plurality of frequencies at the
same time. In this example, when a second wireless transfer station
detects interference using an interference-detecting module 2040 on
a frequency for receiving wireless energy from the first wireless
transfer station, the second wireless transfer station can switch
to another frequency with a decreased amount of interference. In
another embodiment, the first wireless transfer station and/or the
second wireless transfer station can determine an amount of
interference at one or more frequencies by comparing an actual
amount of energy received at the second wireless transfer station
for a selected frequency with an estimated amount of energy and/or
data to be received at the second wireless transfer station for the
selected frequency.
[0150] FIG. 21 illustrates that a wireless transfer station A can
restrict or limit access of one or more other wireless transfer
stations (such as wireless transfer station B, wireless transfer
station C, and wireless transfer station D) to transfer wireless
energy and/or data from wireless transfer station A. In one
embodiment, the wireless transfer station A can receive a wireless
transfer request from the wireless transfer station B, the wireless
transfer station C, and/or the wireless transfer station D, as in
block 2110. In another embodiment, the wireless transfer station A
can authenticate the wireless transfer requests from the wireless

embodiment, when the wireless transfer request is authenticated,
the wireless transfer station A can communicate a wireless transfer
approval message to the wireless transfer station B, the wireless
transfer station C, and/or the wireless transfer station D, as in
block 2130. In one embodiment, the wireless transfer approval
message can include a frequency for the wireless transfer station
B, the wireless transfer station C, and/or the wireless transfer

transfer energy and/or data between the wireless transfer station A
and the wireless transfer station B, the wireless transfer station
C, and/or the wireless transfer station D, as in block 2140.
[0151] FIG. 22 illustrates that a wireless transfer station A can
delay access of one or more other wireless transfer stations (such
as wireless transfer station B, wireless transfer station C, and
wireless transfer station D) to transfer wireless energy and/or
data with wireless transfer station A. In one embodiment, the
wireless transfer station A can receive a wireless transfer request
from the wireless transfer station B, the wireless transfer station
C, and/or the wireless transfer station D, as in block 2210. In
another embodiment, the wireless transfer station A can
authenticate the wireless transfer requests from the wireless
transfer station B, the wireless transfer station C, and/or the
wireless transfer station D, as in block 2220. In another
embodiment, when the wireless transfer request is authenticated by
wireless transfer station A, the wireless transfer station A can
determine an energy level of the wireless transfer station B, the
wireless transfer station C, and/or the wireless transfer station
D, as in block 2230.
[0152] When the energy level of the wireless transfer station B,
the wireless transfer station C, and/or the wireless transfer
station D is above a selected threshold value and/or the energy
level of the device is above a selected threshold value, the
wireless transfer station can send the wireless transfer station B,
the wireless transfer station C, and/or the wireless transfer
station D a wireless transfer delay message, as in block 2240. In
another embodiment, the wireless transfer delay message can include
a waiting time period for the wireless transfer station B, the
wireless transfer station C, and/or the wireless transfer station D
to wait before sending a wireless transfer request. In another
embodiment, the wireless transfer delay message can include a
waiting time period before the wireless transfer station B, the
wireless transfer station C, and/or the wireless transfer station D
can receive wireless energy and/or data from the wireless transfer
station A. In another embodiment, when the wireless transfer
station B, the wireless transfer station C, and/or the wireless
transfer station D receives the wireless energy transfer delay
message, the wireless transfer station B, the wireless transfer
station C, and/or the wireless transfer station D can wait for the
waiting time period and then send another wireless transfer request
(as in block 2250) or receive wireless energy and/or data (as in
block 2260).
[0153] FIG. 23 illustrates that a wireless transfer station A can
control access of one or more other wireless transfer stations
(such as wireless transfer station B, wireless transfer station C,
and wireless transfer station D) to transfer wireless energy and/or
data with wireless transfer station A based on a priority level of
the one or more other wireless transfer stations. In one
embodiment, the wireless transfer station A can receive a wireless
transfer request from the wireless transfer station B, the wireless
transfer station C, and/or the wireless transfer station D, as in
block 2310. In another embodiment, the wireless transfer station A
can authenticate the wireless transfer requests from the wireless
transfer station B, the wireless transfer station C, and/or the
wireless transfer station D, as in block 2320. In one embodiment,
when the wireless energy transfer request is authenticated, the
wireless transfer station A can check a priority level of the
wireless transfer station B, the wireless transfer station C,
and/or the wireless transfer station D, as in block 2330. When a
priority level of the wireless transfer station B, the wireless
transfer station C, and/or the wireless transfer station D is below
a selected threshold value, the wireless transfer station A can
send the wireless transfer station B, the wireless transfer station
C, and/or the wireless transfer station D a wireless transfer
rejection message, as in block 2340. In another embodiment, when
the wireless transfer station A rejects a wireless transfer
request, the wireless transfer station B, the wireless transfer
station C, and/or the wireless transfer station D can be restricted
or prohibited from receiving energy and/or data from wireless
transfer station A, as in block 2350. In another embodiment, the
wireless transfer rejection message can include a waiting time
period for the device to wait before sending another wireless
energy transfer request, as in block 2360. In another embodiment,
when the wireless transfer request is not authenticated, the
wireless transfer station can reject the wireless energy transfer
request.
[0154] FIG. 24 uses a flow chart 2400 to illustrate the
functionality of one embodiment of the computer circuitry with a
wireless transfer station operable to determine when an
unauthorized device may be receiving energy from the wireless
transfer station. The functionality may be implemented as a method
or the functionality may be executed as instructions on a machine,
where the instructions are included on at least one computer
readable medium or one non-transitory machine readable storage
medium. In one embodiment, the computer circuitry can be configured
to select a frequency to transfer energy and/or data with one or
more authorized wireless transfer stations, as in block 2410. In
one embodiment, the computer circuitry can be configured to
transfer energy to one or more authorized wireless transfer
stations and/or one or more devices, as in block 2420. In another
embodiment, the computer circuitry can be configured to determine
when an unauthorized device may be receiving energy from the
wireless transfer station, as in block 2430. In one example, the
wireless transfer station may determine when an unauthorized device
may be receiving energy from the wireless transfer station by
comparing an amount energy received by authorized devices with the
amount of energy transmitted by the wireless transfer station. In
this example, when the difference between the amount of energy
received by authorized devices and the amount of energy transmitted
by the wireless transfer station exceeds a selected threshold, one
or more unauthorized devices may be receiving energy from the
wireless transfer station.
[0155] In one embodiment, when the wireless transfer station
detects one or more unauthorized devices receiving energy from the
wireless transfer station, the wireless transfer station can switch
a present frequency used to transfer the energy to a different
frequency, as in block 2440. In one embodiment, the wireless
transfer station and the one or more authorized wireless transfer
stations can have a predetermined resonant frequency list to
determine the next frequency that the wireless transfer station can
use to transfer energy and/or data with the one or more authorized
wireless transfer stations. In another embodiment, the wireless
transfer station can iterate through the predetermined resonant
frequency list sequentially to transfer energy and/or data with the
one or more authorized wireless transfer stations. In another
embodiment, the wireless transfer station can iterate through the
predetermined resonant frequency list using a predetermined pattern
or algorithm. In another embodiment, when the wireless transfer
station switches the frequency, the wireless transfer station can
communicate to the one or more authorized wireless transfer
stations and/or devices a new frequency to use to transfer wireless
energy and/or data, as in block 2450.
[0156] In one embodiment, when the wireless transfer station
detects one or more unauthorized devices receiving energy from the
wireless transfer station, the wireless transfer station can
deactivate one or more wireless transfer coils. In one example,
when the wireless transfer station detects one or more unauthorized
devices receiving energy from the wireless transfer station the
wireless transfer station can sequentially deactivate wireless
transfer coils to determine which wireless transfer coil the
unauthorized device is receiving energy from. In one embodiment,
the wireless transfer station, the other wireless transfer
stations, and/or the authorized devices can tolerate a wider range
of frequency variations for transferring wireless energy.
[0157] FIG. 25 uses a flow chart 2500 to illustrate the
functionality of one embodiment of the computer circuitry with a
wireless transfer station operable to determine when one or more
other wireless transfer stations and/or one or more devices is
authorized to transfer energy and/or data with the wireless
transfer station. The functionality may be implemented as a method
or the functionality may be executed as instructions on a machine,
where the instructions are included on at least one computer
readable medium or one non-transitory machine readable storage
medium. In one embodiment, the computer circuitry can be configured
to receive ID information or security information from the one or
more other wireless transfer stations and/or the one or more
devices, as in block 2510. In another embodiment, the computer
circuitry can be configured to use the ID information or security
information to determine if the one or more other wireless transfer
stations and/or the one or more devices are authorized to transfer
energy and/or data with the wireless transfer station, as in block
2520. In another embodiment, when the one or more other wireless
transfer stations and/or the one or more devices are not authorized
to receive energy from the wireless transfer station, the computer
circuitry can be configured to deny or ignore the request to
receive energy and/or data from the one or more other wireless
transfer stations and/or the one or more devices, as in block 2530.
In another embodiment, when from the one or more other wireless
transfer stations and/or the one or more devices are authorized to
receive energy from the wireless transfer station, the computer
circuitry can be configured to determine a priority of the one or
more other wireless transfer stations and/or the one or more
devices to transfer energy and/or data with the wireless transfer
station, as in block 2540. In another embodiment, the computer
circuitry can be configured to transfer energy and/or data with the
one or more other wireless transfer stations and/or the one or more
devices based on the determined priority, as in block 2550.
[0158] In one embodiment, when the one or more other wireless
transfer stations and/or the one or more devices are unable to
provide security information, the wireless transfer station can
deny the request for a transfer of energy and/or data. In another
embodiment, when the one or more other wireless transfer stations
and/or the one or more devices are unable to provide security
information, the wireless transfer station can place the transfer
request at the bottom of a transfer queue.
[0159] FIG. 26 uses a flow chart 2600 to illustrate the
functionality of one embodiment of the computer circuitry with a
wireless transfer station operable to communicate data with one or
more other wireless transfer stations and/or one or more devices
using a communications module (as shown in FIG. 4). The
functionality may be implemented as a method or the functionality
may be executed as instructions on a machine, where the
instructions are included on at least one computer readable medium
or one non-transitory machine readable storage medium. In one
embodiment, the computer circuitry can be configured to transfer
encrypted information communicated between the wireless transfer
station and a selected wireless transfer station, as in block 2610.
In another embodiment, the computer circuitry can be configured to
communicate a decryption key to the selected wireless transfer
station, as in block 2626. In another embodiment, the selected
wireless transfer station can be configured use the decryption key
from the wireless transfer station to decrypt and access the data
transferred from the wireless transfer station and/or to use to
initiate or access a transfer of energy with the wireless transfer
station, as in block 2630. In another embodiment, when the selected
wireless transfer station is authorized to transfer energy and/or
data with the wireless transfer station, the selected wireless
transfer station can use a predetermined authentication key. In
another embodiment, the selected wireless transfer station can
request the wireless transfer station send an authentication key
for the selected wireless transfer station to use for
authentication.
[0160] In one embodiment, the wireless transfer station can
determine when an authorized wireless transfer station is in a
coverage area of the wireless transfer station before transferring
the energy and/or data. In another embodiment, the authorized
wireless transfer station transferring energy and/or information
with the wireless transfer station can provide a user with an alert
to not remove the authorized wireless transfer station from a
coverage area of the wireless transfer station until an energy
transfer and/or a data transfer is complete between the wireless
transfer station and the authorized wireless transfer station. In
one embodiment, when the wireless transfer station detects one or
more unauthorized wireless transfer stations receiving wireless
energy and/or data, the wireless transfer station can alert a third
party of the unauthorized wireless transfer stations.
[0161] In another embodiment, another wireless transfer station or
a device can have an authentication dongle coupled to the other
wireless transfer station or the device to transfer wireless energy
and/or data from the wireless transfer station. In one embodiment,
the authentication dongle can include a wireless transfer coil to
transfer energy and/or data with the wireless transfer station. In
another embodiment, the wireless transfer station can communicate
with the authentication dongle to verify the other wireless
transfer station or the device is authorized to transfer energy
and/or data with the wireless transfer station.
[0162] In one example, when a device requests to receive energy
from the wireless transfer station, the wireless transfer station
can authenticate the device using a coupled authentication dongle.
In this example, when the wireless transfer station authenticates
that the device has an authorization dongle coupled to the device,
the wireless transfer station can communicate a frequency to the
device for the device to use to transfer energy and/or data with
the wireless transfer station. In one embodiment, when the wireless
transfer station verifies that the other wireless transfer station
or the device has an attached authorization dongle, the wireless
transfer station can communicate a frequency to the other wireless
transfer station or the device via the authentication dongle. In
another embodiment, the authentication dongle can receive a key
from wireless transfer station to activate a wireless transfer coil
attached to the device or integrated into the device.
[0163] FIG. 27 illustrates a wireless transfer station 2710. FIG.
27 further illustrates that the wireless transfer station 2710 can
include a wireless transfer coil 2720, a power management module
2730, and an energy leak detector 2740. In one embodiment, the
energy leak detector 2740 can determine when an unauthorized device
is absorbing or receiving energy from a coverage area of the
wireless transfer station 2710. In another embodiment, the energy
leak detector 2740 can detect when foreign materials and/or
unauthorized devices are interfering with an energy transfer
between the wireless transfer station 2710 and an authorized device
or an authorized wireless transfer station. In another embodiment,
the energy leak detector can determine if there is an energy leak
by comparing the expected energy received by the authorized device
and/or the authorized wireless transfer station with the actual
amount of energy transmitted by the wireless transfer station
2710.
[0164] FIG. 28 shows a wireless transfer station 2810 configured to
communicate with other wireless transfer stations 2820, 2830,
and/or 2840 and determine which of the one or more other wireless
transfer stations 2820, 2830, and/or 2840 is capable and/or
available to provide energy to a selected device and/or a selected
wireless transfer station. In one example, the selected device or
the selected wireless transfer station can send a wireless transfer
request to the wireless transfer station. When the wireless
transfer station 2810 is not compatible with the selected device or
the wireless transfer station 2810 is not available to provide
energy to the selected device, the wireless transfer station 2810
can communicate with the one or more other wireless transfer
stations 2820, 2830, and/or 2840 to locate an available wireless
transfer station of the one or more other wireless transfer
stations 2820, 2830, and/or 2840 for the selected device or the
selected wireless transfer station to receive wireless energy. When
the wireless transfer station 2810 determines that available
wireless transfer station can provide energy to the selected device
or the selected wireless transfer station, the wireless transfer
station 2810 can provide the selected device or the selected
wireless transfer station with transfer station information for the
available wireless transfer station.
[0165] In one embodiment, the transfer station information can
include: directions to one of the other wireless transfer stations
2820, 2830, or 2840; authentication information to receive energy
from the other wireless transfer stations 2820, 2830, or 2840; a
number of available wireless transfer coils at the other wireless
transfer stations 2820, 2830, or 2840; a type of wireless transfer
coils available at the other wireless transfer stations 2820, 2830,
or 2840; an energy capabilities of the other wireless transfer
stations 2820, 2830, or 2840; and so forth. In one embodiment, when
more than one of the other wireless transfer stations 2820, 2830,
or 2840 are available to provide energy to the selected wireless
transfer station or the selected device, the selected wireless
transfer station or the selected device can select which one of the
one or more other wireless transfer stations 2820, 2830, or 2840 to
receive energy from based on charging criteria. The charging
criteria can include: an energy output capability of each of the
one or more available other wireless transfer stations 2820, 2830,
or 2840; a location of each of the one or more available other
wireless transfer stations 2820, 2830, or 2840; a distance from the
selected device or the selected wireless transfer station to each
of the one or more available other wireless transfer stations 2820,
2830, or 2840; a number of other devices or other wireless transfer
stations receiving energy from each of the one or more available
other wireless transfer stations 2820, 2830, or 2840, and so
forth.
[0166] In one example, the wireless transfer station 2810 is not
compatible with the selected device or the selected wireless
transfer station when a wireless transfer coil of the selected
device or wireless transfer coils of the selected wireless transfer
station are a different shape or size than a wireless transfer coil
of the wireless transfer station 2810. In another example, the
wireless transfer station 2810 is not compatible with the selected
device or the selected wireless transfer station when a wireless
transfer coil of the selected device or a wireless transfer coil of
the selected wireless transfer station receives data and/or
wireless energy at a different resonant frequency range than a
resonant frequency range of a wireless transfer coil of the
wireless transfer station 2810.
[0167] FIG. 29 shows a wireless transfer station 2910 transferring
energy and/or data with one or more wireless transfer stations
and/or devices 2920, 2930, and 2940 within a selected range 2950.
In one embodiment, the wireless transfer station 2910 can adjust
the selected range 2950 based on selected criteria, such as a
number of wireless transfer stations and/or devices within a
threshold range of the wireless transfer station 2910, a number of
devices or other wireless transfer stations the wireless transfer
station 2910 can support transferring energy and/or data to, and so
forth. In one example, the wireless transfer station 2910 can
transfer energy and/or data with wireless transfer stations and/or
devices 2920, 2930, and 2940 that are within the selected range
2950 and not transfer energy and/or data with wireless transfer
station and/or device 2960.
[0168] In one embodiment, a wireless transfer station can use a
plurality of resonant frequencies to transfer energy to one or more
devices or one or more other wireless transfer stations. In another
embodiment, the wireless transfer station can provide different
amounts of energy to different devices or other wireless transfer
stations at different resonant frequencies. In one example, a first
wireless transfer station can receive wireless energy from a
primary wireless transfer station at a first resonant frequency and
a second wireless transfer station can receive wireless energy from
the primary wireless transfer station at a second resonant
frequency.
[0169] In one embodiment, the primary wireless transfer station can
set priority levels for the different devices or other wireless
transfer stations receiving wireless energy at different resonant
frequencies. In one example, a first wireless transfer station with
a highest priority can receive wireless energy from the primary
wireless transfer station at a first selected resonant frequency
and a second wireless transfer station with a lower priority can
receive wireless energy from the primary wireless transfer station
at a second selected resonant frequency.
[0170] In one embodiment, the primary wireless transfer station may
not have the capability to provide wireless energy to all the
devices and/or other wireless transfer stations requesting wireless
energy transfer. When the primary wireless transfer station does
not have the capability to support all of the and/or other wireless
transfer stations requesting wireless transfer requesting wireless
energy transfer, the primary wireless transfer station can transfer
energy to selected devices based on an energy transfer priority. In
one embodiment, the primary wireless transfer station can select
different resonant frequencies to transfer energy to different
devices based on the energy transfer priority of the device. In one
example, the primary wireless transfer station can be capable of
supporting energy transfer for a combination of up to 5 devices
and/or other wireless transfer stations and 10 devices and other
wireless transfer stations can request wireless energy transfer. In
this example, the primary wireless transfer station can determine
the priority of the 10 devices and/or other wireless transfer
stations and select 5 devices and/or other wireless transfer
stations to transfer energy to. The primary wireless transfer
station can select one or more resonant frequencies to transfer
energy to the 5 devices. The remaining devices can be de-selected
(e.g. not selected) for charging by not tuning transmitting coils
to frequencies of the remaining devices. In one embodiment, the
remaining devices can be selected and charged after the first 5
have been charged.
[0171] In one embodiment, a transmission frequency of a wireless
transfer coil of a wireless transfer station for transferring
wireless energy can be based on a natural frequency of the wireless
transfer station, a device, and/or a wireless transfer coil
wireless of another wireless transfer station.
[0172] In one embodiment, the wireless transfer station can
regulate an amount of energy received by one or more other wireless
transfer stations. In one example, when a first wireless transfer
station uses a wireless transfer coil to transfer energy, the first
wireless transfer station can control the amount of energy received
at a second wireless transfer station by detuning a frequency of
the wireless transfer coil of the first wireless transfer station
by a selected amount. In another example, the first wireless
transfer station can control the amount of energy received from the
second wireless transfer station by detuning a frequency of the
wireless transfer coil of the first wireless transfer station by
selected amount.
[0173] FIG. 30 shows a wireless transfer coil 3010 with a plurality
of loops or winds 3020. In one embodiment, an amount of energy
transmitted and/or received by the wireless transfer coil 3010 can
be adjusted using one or more adjustment modules 3030. In one
embodiment, the one or more adjustment modules 3030 can engage or
disengage one or more of the plurality of loops 3020 to:
effectively vary a size of the wireless transfer coil 3010; change
a number of active loops of the wireless transfer coil 3010; change
a shape of a magnetic field of the wireless transfer coil 3010;
change an amount of energy transferred using the wireless transfer
coil 3010; or enable or disable selected devices from receiving
energy and/or data from the wireless transfer coil 3010.
[0174] In one embodiment, the one or more adjustment modules 3030
can be one or more switches, such as an impedance matching switch
or an on/off switch. In one example, a selected number of the
plurality of loops 3020 can be engaged by turning on one or more of
the corresponding switches and a selected number of the plurality
of loops 3020 can be disengaged by turning off one or more of the
corresponding switches.
[0175] In one embodiment, a resonant frequency between of the
wireless transfer coil 3010 can be dynamically adjusted using the
one or more adjustment modules 3030. In one embodiment, the one or
more adjustment modules 3030 can be adjustable energy oscillators.
In another embodiment, the one or more adjustment modules 3030 can
be variable capacitors, variable inductors, and/or variable
inductors and the respective capacitance, resistance, and/or
inductance can be changed to tune or detune the wireless transfer
coil 3010.
[0176] In one embodiment, a wireless transfer coil of a first
wireless transfer station can have a fixed impedance and/or
resonant frequency and an impedance and/or resonant frequency of a
second wireless transfer coil of a second wireless transfer station
can be adjustable. In another embodiment, the impedance and/or
resonant frequency of the wireless transfer coil of the first
wireless transfer station and the impedance and/or resonant
frequency of the wireless transfer coil of the second wireless
transfer station can each be adjustable.
[0177] Traditionally, wireless energy or data transfer using
wireless transfer coils has been limited because of alignment
requirements. Depending on a level of misalignment between wireless
transfer coils, a receiving coil may only receive a partial amount
of energy from a transmitting coil or receive substantially none of
the energy transferred from the transmitting coil. Additionally, a
wireless energy transfer has traditionally been limited by a
distance between the transmitting coil and the receiving coil.
[0178] FIG. 31 shows a first wireless transfer coil 3110 emitting a
magnetic field 3130 and a second wireless transfer coil 3120 that
is partially aligned or partially coupled with the magnetic field
3130 of the first wireless transfer coil 3110. In one example, the
first wireless transfer coil 3110 can be configured to emit the
magnetic field 3130 with a selected field range. In this example,
when the second wireless transfer coil 3120 is only partially
located within the magnetic field 3130, the second wireless
transfer coil 3120 may only be partially aligned or partially
coupled. In one embodiment, when the second wireless transfer coil
3120 is only partially aligned or partially coupled, the second
wireless transfer coil 3120 may receive a partial data and/or
energy transfer or substantially no data and/or energy
transfer.
[0179] In one embodiment, an efficiency of a transfer of energy
between a first wireless transfer station and a second wireless
transfer station using magnetic inductive coupling or magnetic
resonant coupling is inversely proportional to a spatial separation
between a transmitting coil of the first wireless transfer station
and a receiving coil of the second wireless transfer station. As
previously discussed, placing the wireless transfer stations within
the near field distance limits can substantially increase the
efficiency of the energy transfer.
[0180] Returning to FIG. 30, in one embodiment, the wireless
transfer station can use a combination of techniques to adjust: a
size, a shape, and/or a coverage range of a magnetic field of the
wireless transfer coil 3010; a coupling distance between a
transmitting coil and a receiving coil; and/or a range of alignment
positions of the receiving coil relative to the transmitting coil.
In one example, the wireless transfer station can include an array
of multiple wireless transfer coils and/or Ferrite material, as
discussed in the proceeding paragraphs. In one embodiment, the
Ferrite material can be used to adjust a size, a shape, and/or a
coverage range of a magnetic field of one or more wireless transfer
coils 3010. In another embodiment, the wireless transfer station
can change an amount of energy provided to one or more wireless
transfer coils in a wireless transfer coil array by adjusting a
size, a shape, and/or a coverage range of the magnetic field.
[0181] In one embodiment, to adjust a threshold coupling distance
between a transmitting coil of a first wireless transfer station
and a receiving coil of a second wireless transfer station, a size
of the transmitting coil of the first wireless transfer station can
be adjusted and/or a size of the receiving coil of the second
wireless transfer station can be adjusted. In another embodiment,
to adjust a range of alignment positions, angles, and/or locations
of the receiving coil relative to the transmitting coil, the size
or the shape of the transmitting coil and/or the receiving coil can
be adjusted.
[0182] In one embodiment, one or more adjustment modules 3030 can
adjust a size or a shape of a wireless transfer coil 3010, such as
the transmitting coil and/or the receiving coil. In one example, a
selected number of the plurality of loops 3020 can be engaged or
disengaged by using the one or more adjustment modules 3030 to
adjust the size and/or shape of the wireless transfer coil 3030. In
one embodiment, a size of a magnetic field can correspond to a size
of the wireless transfer coil 3030. In one example, as the size of
the wireless transfer coil 3010 increases the size of the magnetic
field also increases, and vice versa. In one embodiment, one or
more adjustment modules 3030 can adjust a transmitting coil size to
create a selected magnetic field size.
[0183] In one embodiment, a resonant frequency between one or more
wireless transfer coils 3010 can be dynamically adjusted using the
one or more adjustment modules 3030. In another embodiment, the
size and/or shape of the magnetic field can be adjusted by changing
an orientation of the transmitting coil. In another embodiment, the
size and/or shape of the magnetic field can be adjusted using
Ferrite material. In one embodiment, the one or more adjustment
modules 3030 of a wireless transfer station can dynamically adjust
a size and/or a shape of a magnetic field (such as an
electromagnetic field) of one or more wireless transfer coils 3010
based on a location where the wireless transfer station is used or
an environment where the wireless transfer station is used.
[0184] In one embodiment, the size and/or shape of the magnetic
field of a wireless transfer station can be adjusted using a phased
array of multiple wireless transfer coils. In one example, the
phased array of the multiple wireless transfer coils can be a
plurality of transmitting coils configured for resonant coupling
arranged in a form of an array, e.g. a transmitter resonant phased
array. In another embodiment, each of the wireless transfer coils
3010 in the phased array can be associated with one or more
adjustment modules 3030, such as selected capacitors. A selected
wireless transfer coil 3010 and an associated one or more
adjustment modules 3030 can form a tuned circuit that can be tuned
to a selected frequency or frequency range. In another embodiment,
each of the plurality of wireless transfer coil 3010 can be
adjusted to transmit energy at different frequency levels and/or
energy levels.
[0185] In one embodiment, a wireless transfer station can use a
plurality of resonant frequencies to transfer energy to one or more
devices or one or more other wireless transfer stations. In another
embodiment, the wireless transfer station can provide different
amounts of energy to different devices or other wireless transfer
stations at different resonant frequencies. In one example, a first
wireless transfer station can receive wireless energy from a
primary wireless transfer station at a first resonant frequency and
a second wireless transfer station can receive wireless energy from
the primary wireless transfer station at a second resonant
frequency.
[0186] In one embodiment, the primary wireless transfer station can
set priority levels for the different devices or other wireless
transfer stations receiving wireless energy at different resonant
frequencies. In one example, a first wireless transfer station with
a highest priority can receive wireless energy from the primary
wireless transfer station at a first selected resonant frequency
and a second wireless transfer station with a lower priority can
receive wireless energy from the primary wireless transfer station
at a second selected resonant frequency.
[0187] In one embodiment, the primary wireless transfer station may
not have the capability to provide wireless energy to all the
devices and/or other wireless transfer stations requesting wireless
energy transfer. When the primary wireless transfer station does
not have the capability to support all of the and/or other wireless
transfer stations requesting wireless transfer requesting wireless
energy transfer, the primary wireless transfer station can transfer
energy to selected devices based on an energy transfer priority. In
one embodiment, the primary wireless transfer station can select
different resonant frequencies to transfer energy to different
devices based on the energy transfer priority of the device. In one
example, the primary wireless transfer station can be capable of
supporting energy transfer for a combination of up to 5 devices
and/or other wireless transfer stations and 10 devices and other
wireless transfer stations can request wireless energy transfer. In
this example, the primary wireless transfer station can determine
the priority of the 10 devices and/or other wireless transfer
stations and select 5 devices and/or other wireless transfer
stations to transfer energy to. The primary wireless transfer
station can select one or more resonant frequencies to transfer
energy to the 5 devices. The remaining devices can be de-selected
(e.g. not selected) for charging by not tuning transmitting coils
to frequencies of the remaining devices. In one embodiment, the
remaining devices can be selected and charged after the first 5
have been charged.
[0188] In one embodiment, the wireless transfer station can assign
different priority levels to different devices or other wireless
transfer stations. The wireless transfer station can determine the
amount of energy that the wireless transfer station has available
to transfer to one or more devices and/or the one or more other
wireless transfer stations and prioritize the one or more devices
and/or the one or more other wireless transfer stations that can
receive energy and/or the amount of energy that the one or more
devices and/or the one or more other wireless transfer stations can
receive.
[0189] In one embodiment, a selected number of devices and/or a
selected number of other wireless transfer stations can each
request to receive energy from the wireless transfer station and/or
to continue to receive energy from the wireless transfer station.
The wireless transfer station can prioritize the devices and the
other wireless transfer stations based on selected priority
criteria. In one embodiment, the selected priority criteria can
include: a type of device or wireless transfer station, a present
energy level of the device or the other wireless transfer station,
a present energy level of the wireless transfer station, a number
of devices or other wireless transfer stations that are requesting
energy from the wireless transfer station, and so forth.
[0190] In one embodiment, when a plurality of devices and/or other
wireless transfer stations request to receive energy from the
wireless transfer station, the wireless transfer station can
determine a present energy level of one or more of the devices
and/or the other wireless transfer stations and populate a priority
list based on the present energy level of the one or more of the
devices and/or the other wireless transfer stations. In one
example, a device or another wireless transfer station with the
lowest present energy level can be placed at the top of the
priority list. The device or other wireless transfer station with
the second lowest present energy level can be placed second from
the top of the priority list, and so forth.
[0191] In one embodiment, the wireless transfer station can
communicate to the one or more devices and/or the one or more other
wireless transfer stations: a frequency that each device and/or
other wireless transfer station can receive energy, an amount of
energy each device and/or the other wireless transfer station can
receive, a period of time that the device and/or the wireless
transfer station can receive the wireless energy, a voltage level,
a current level, and so forth. In one embodiment, the wireless
transfer station can coordinate transferring energy to different
devices and/or other wireless transfer stations at different times.
In another embodiment, the wireless transfer station can determine
the amount of energy the wireless transfer station transfers to
each device and/or other wireless transfer station. In one
embodiment, the wireless transfer station can dynamically adjust
the frequency that the energy and/or data is transferred on and/or
the amount of energy transferred to each device or other wireless
transfer station.
[0192] In one embodiment, the wireless transfer station can assign
different frequencies to the one or more devices and/or the one or
more other wireless transfer stations to enable the wireless
transfer station to differentiate the amount of energy each device
or other wireless transfer station is receiving, e.g. enabling
unique usage metering for each device or other wireless transfer
station.
[0193] In one embodiment, the wireless transfer station can adjust
an amount of energy and/or number of wireless transfer coils
transferring energy based on a number of devices and/or other
wireless transfer stations requesting energy and/or receiving
energy. In another embodiment, the wireless transfer station can
alternate providing energy to one or more devices and/or other
wireless transfer stations. In one example, the wireless transfer
station can receive requests from multiple devices and other
wireless transfer stations for an energy transfer. When the
wireless transfer station does not have the capability to provide
energy to all of the devices and the other wireless transfer
stations requesting energy simultaneously, the wireless transfer
station can provide energy to selected devices and/or other
wireless transfer stations for a selected period of time and then
switch to providing energy to different selected devices and other
wireless transfer stations for a selected period of time. One
advantage of alternating providing energy to different devices and
other wireless transfer stations can be to enable the wireless
transfer station to provide energy to multiple devices and/or other
wireless transfer stations while conserving energy. For example, if
the wireless transfer station has 25 percent energy remaining and a
plurality of the devices and the other wireless transfer stations
are requesting to receive energy, the wireless transfer station can
alternate providing energy to the devices and the other wireless
transfer stations to enable the devices and the other wireless
transfer stations to avoid becoming completely drained of energy,
while conserving energy of the wireless transfer station until the
wireless transfer station can be recharged.
[0194] In one embodiment, a wireless transfer station can operate
in different modes, such as a sleep mode, a charging mode, a fully
charged mode, a ready for use mode, an error mode, a shut off mode,
and so forth. In one example, when the wireless transfer station is
fully charged or charged above a selected threshold the wireless
transfer station can enter a fully charged mode or a ready for use
mode. In another example, when the wireless transfer station has
not been in use for a selected period of time, the wireless
transfer station can stop transferring energy to one or more
devices and enter a sleep mode. One advantage of shutting off or
entering a sleep mode after a selected period of time can be to
prevent the wireless transfer station from leaking energy when a
device has been fully charged by the wireless transfer station
and/or the device is no longer in use. In another embodiment, when
the wireless transfer station has been coupled with a device or
other wireless transfer station, the wireless transfer station can
enter an active mode, e.g. a mode to transfer energy to one or more
devices or other wireless transfer stations in the coverage area of
the battery pack. In another embodiment, a wireless transfer
station display can display a mode that the wireless transfer
station is operating in.
[0195] FIG. 32a depicts a wireless transfer station 3210 that
includes a near field communications module 3220. In one
embodiment, a wireless transfer station 3210 and another device
must be in close proximity to communicate data or information using
the near field communications module 3220. In one example, the
wireless transfer station 3210 can be integrated into a medical
cart. In this example, when a caregiver desires to charge a device
or communicate information with the wireless transfer station 3210,
the caregiver can place the device adjacent to the wireless
transfer station 3210, such as on top of a work platform of a
medical cart. When the device is placed adjacent to the work
platform, the wireless transfer station 3210 can verify an
authentication level of the device using a near field
communications module 3220. When the wireless transfer station 3210
determines that the device is an authorized device, the wireless
transfer station can determine if the device is requesting an
energy transfer and/or a data transfer. When the device is
requesting a data transfer, the wireless transfer station 3210 can
use the near field communications module 3220 to communicate the
data. In one embodiment, the near field communications module 3220
can be couple to a wireless transfer coil 3230 and the near field
communications module 3220 can use the wireless transfer coil 3230
to transfer energy and/or data with another wireless transfer
station and/or device.
[0196] One advantage of using the near field communications module
3220 to communicate data can be an increase in data transfer
security. In one example, when a device communicates data with the
wireless transfer station 3210 using the near field communications
module 3220, the device must be adjacent to the wireless transfer
station 3210 or within a selected distance of the wireless transfer
station 3210. In this example, where the device must be adjacent to
the wireless transfer station 3210 to use the near field
communications module 3220, when the wireless transfer station 3210
authenticates the device and communicates information with the
device, it is more difficult for an unauthorized individual or
device to gain access to the wireless transfer station 3210 using
the near field communications module 3220 remotely (e.g. outside
the selected distance of the wireless transfer station 3210).
[0197] In one embodiment, a wireless transfer station can receive
identification information or security information from a device or
another wireless transfer station requesting a wireless energy
transfer. In another embodiment, the security information can
include a pin code, a biometric authentication, and so forth. In
another embodiment, the identification information can include a
user identity (ID), a device ID, and/or a station ID.
[0198] In another embodiment, the wireless transfer station can use
the identification information or security information to determine
if the requesting device or the requesting other wireless transfer
station is authorized to receive energy from the wireless transfer
station. In another embodiment, when the device of the other
wireless transfer station is not authorized to receive energy from
the wireless transfer station, the wireless transfer station can
deny or ignore the request to receive energy. In another
embodiment, when the device of the other wireless transfer station
is authorized to receive energy from the wireless transfer station,
the wireless transfer station can then determine a priority that
the requesting device or the other requesting wireless transfer
station can receive energy relative to other devices and/or
additional wireless transfer station.
[0199] In one embodiment, when the device or the other wireless
transfer station is unable to provide security information and/or
the wireless transfer station does not receive the security
information, the wireless transfer station can deny the request to
provide the wireless energy transfer. In another embodiment, when
the device or the other wireless transfer station is unable to
provide security information, the wireless transfer station can
place the request to provide energy at the bottom of an
energy-receiving queue.
[0200] FIG. 32b shows a wireless transfer station 2810 with devices
2820 and 2830 abutting a surface of the wireless transfer station
2810 with one or more wireless transfer coils for transferring
energy and/or data. In one embodiment, the wireless transfer
station 2810 can transfer energy and/or data with authorized device
2820 and/or unauthorized device 2830 and/or other wireless transfer
stations. In one embodiment, only an authorized wireless transfer
station and/or authorized device 2820 can transfer energy and/or
data with the wireless transfer station 2810. In another
embodiment, an unauthorized wireless transfer station and/or an
unauthorized device 2830 can transfer energy and/or data with the
wireless transfer station. In one example, when the wireless
transfer station 2810 is integrated into a work surface of a
wheeled medical cart, a doctor may place an unauthorized device
2830 (such as a personal cellphone) on the work surface of wheeled
medical cart to receive energy and/or data. In one embodiment, when
the unauthorized device 2830 is placed within a coverage range of
the wireless transfer station 2810, the wireless transfer station
2810 can provide temporary access to the unauthorized device 2830.
In one example, the unauthorized device 2830 can have a wireless
transfer computer application on the unauthorized device 2830 to
verify an identity of a user of the unauthorized device 2830 and a
wireless transfer computer application can provide temporary access
information to the wireless transfer station 2810. In this example,
when the wireless transfer station 2810 receives the temporary
access information, the wireless transfer station 2810 can transfer
energy and/or data with the unauthorized device 2830.
[0201] In one embodiment, the wireless transfer computer
application can provide a graphical interface for the user of the
unauthorized device 2830 to input security information, such as a
pin code or biometric authentication. In another embodiment, when
the wireless energy computer application verifies input security
information, the wireless energy computer application can
communicate the temporary authorization to the wireless transfer
station 2810. In another embodiment, when the temporary
authorization is granted, the wireless transfer station 2810 can
communicate connection information to the temporarily authorized
device 2830, such as a decryption code to transfer data with the
wireless transfer station 2810 or a frequency to transfer energy
with the wireless transfer station 2810. In another embodiment, the
temporary authorization can be for a selected period of time. In
one example, when the wireless transfer station is part of a
wheeled medical cart, a doctor may desire to use his smartphone (an
unauthorized device 2830) to transfer data and/or energy with the
wireless transfer station 2810 during the doctor's shift. When the
smartphone is temporarily authorized, the smartphone can transfer
energy and/or data with the wireless transfer station 2810 while
the doctor is on duty for work, such as for a selected number of
minutes or hours, and so forth.
[0202] In one embodiment, the temporary authorization can be valid
while the temporarily authorized device 2830 is within the coverage
range of the wireless transfer station 2810. In one example, when
the wireless transfer station 2810 is part of a wheeled medical
cart, a doctor may use his smartphone (an unauthorized device 2830)
to transfer data and/or energy with the wireless transfer station
2810 while the doctor is adjacent to the wheeled medical cart. In
another embodiment, when the temporarily authorized device 2830
leaves the coverage area of the wireless transfer station 2810, the
temporary authorization can end. In another embodiment, when the
temporarily authorized device 2830 returns to the wireless transfer
station coverage area, to transfer data or energy again, the user
ID of the temporarily authorized device 2830 can be verified again.
In another embodiment, the temporarily authorized device 2830 can
leave the coverage area for a selected period of time and re-enter
the coverage area while maintaining the temporary authorization. In
one example, a doctor can be using his smartphone to transfer data
and/or energy with the wireless transfer station and then receive a
phone call on his smartphone. In this example, the doctor can
remove the smartphone from the coverage area to take the phone call
and then replace the smartphone in the coverage area while
maintaining the temporary authorization.
[0203] In one embodiment, when the wireless transfer station
determines that one or more devices and/or one or more other
wireless transfer stations are authorized to transfer energy and/or
data with the wireless transfer station, the wireless transfer
station can direct or steer the wireless energy and/or data to
enable the authorized one or more devices and/or the authorized one
or more other wireless transfer stations to receive energy while
avoiding providing energy to unauthorized devices and/or other
unauthorized wireless transfer stations. In one embodiment, the
wireless transfer station can direct or steer the transmitted
wireless energy by increasing or decreasing an amount of energy
that is transmitted from a wireless transfer coil. In another
embodiment, the wireless transfer station can direct or steer the
transmitted wireless energy using beamforming. In another
embodiment, the wireless transfer station can narrow or expand the
coverage scope of wirelessly transmitted energy or data by varying
a wireless transfer coil (as discussed in the preceding
paragraphs).
[0204] FIG. 33 uses a flow chart 3300 to illustrate the
functionality of one embodiment of the computer circuitry with a
wireless transfer station operable to authenticate a wireless
transfer. The functionality may be implemented as a method or the
functionality may be executed as instructions on a machine, where
the instructions are included on at least one computer readable
medium or one non-transitory machine readable storage medium. In
one embodiment, the wireless transfer station can be configured to
receive, from another wireless transfer station, a wireless
transfer station identification (ID) message, as in block 3310. In
another embodiment, the wireless transfer station can be further
configured to authenticate the wireless transfer station ID message
to determine a permission level of the other wireless transfer
station, as in block 3320. In another embodiment, the wireless
transfer station can be further configured to provide wireless
energy or data to the other wireless transfer station based on the
permission level of the other wireless transfer station using a
wireless transfer coil of the wireless transfer station, as in
block 3330.
[0205] In one embodiment, the wireless transfer station can be
further configured to: determine a selected energy charge rate or a
selected energy charge amount of the other wireless transfer
station based on the wireless transfer station ID message; and
provide energy to the other wireless transfer station at the
selected energy charge rate; or provide energy to the other
wireless transfer station to the selected energy charge amount. In
another embodiment, the energy charge rate for the other wireless
transfer station can be based on a voltage range or a current range
for the other wireless transfer station to receive energy. In
another embodiment, the energy charge rate for the other wireless
transfer station can be based on the energy charge amount is a
maximum capacity level amount of energy the other wireless transfer
station is configured to receive. In another embodiment, the
wireless transfer station can be further configured to: determine
when one or more wireless transfer coils are available to provide
energy or data to the other wireless transfer station; and provide
energy or data to one or more wireless transfer stations using at

another embodiment, the wireless transfer station can be further
configured to: receive a transfer request from the other wireless
transfer station and send a transfer approval message when the
wireless transfer station authenticates the wireless transfer
station ID message of the other wireless transfer station.
[0206] In one embodiment, the wireless transfer station can be
further configured to: receive transfer requests from a plurality
of other wireless transfer stations; receive wireless transfer
station identification (ID) messages for each of the plurality of
other wireless transfer stations; and generate a priority list of a
priority level of each of the plurality of other wireless transfer
stations to receive energy or data from the wireless transfer
station based on the wireless transfer station ID messages of each
of the plurality of other wireless transfer stations. In another
embodiment, the priority list can be based on: a type of device
that the other wireless transfer station is attached to that is
requesting the wireless transfer; a remaining energy level of the
wireless transfer station; or a charging priority value assigned to
each other wireless transfer station requesting the wireless
transfer. In another embodiment, the wireless transfer station can
be further configured to dynamically adjust the priority level of
one or more of the other wireless transfer stations.
[0207] In one embodiment, the wireless transfer station can be
further configured to determine when the wireless transfer station
ID message of a selected one of the plurality of other wireless
transfer stations is invalid and prioritize the selected other
wireless transfer station below a plurality of authenticated
wireless transfer stations for receiving a wireless transfer of
energy or data. In another embodiment, the wireless transfer
station can be further configured to determine when a wireless
transfer station ID message for the other wireless transfer station
is invalid based on the authentication of the wireless transfer
station ID message and create a temporary wireless transfer station
ID for the other wireless transfer station. In another embodiment,
the wireless transfer station can be further configured to
determine when a wireless transfer station ID message for the other
wireless transfer station is invalid based on the authentication of
the wireless transfer station ID message and send a transfer denial
message to the other wireless transfer station.
[0208] In one embodiment, the wireless transfer station can be
further configured to determine when an unauthenticated wireless
transfer station is receiving wireless energy or data from the
wireless transfer station and alert a user of the wireless transfer
station or a third party that the unauthenticated wireless transfer
station is receiving wireless energy or data from the wireless
transfer station. In another embodiment, the wireless transfer
station can be further configured to: determine when an
unauthenticated wireless transfer station is receiving wireless
energy or data from the wireless transfer station; and adjust a
frequency of one or more wireless transfer coils of the wireless
transfer station at which the unauthenticated wireless transfer
station is receiving energy or data; or turn off one or more
wireless transfer coils that the unauthenticated wireless transfer
station is receiving energy or data from. In another embodiment,
the wireless transfer station can be further configured to
determine that the other wireless transfer station is compatible to
receive energy or data from the wireless transfer station using a
wireless request message received from the other wireless transfer
station.
[0209] FIG. 34 uses a flow chart 3400 to illustrate the
functionality of one embodiment of the computer circuitry with a
wireless transfer station operable to receive wireless energy. The
functionality may be implemented as a method or the functionality
may be executed as instructions on a machine, where the
instructions are included on at least one computer readable medium
or one non-transitory machine readable storage medium. In one
embodiment, the wireless transfer station can be configured
communicate, to another wireless transfer station, a wireless
energy transfer request, as in block 3410. In another embodiment,
the wireless transfer station can be further configured to
communicate, to the other wireless transfer station, a wireless
transfer station identification (ID) message for authentication to
receive wireless energy from the other wireless transfer station,
as in block 3420. In another embodiment, the wireless transfer
station can be further configured to receive, from the other
wireless transfer station, a wireless energy transfer approval
message upon authentication of the wireless transfer station ID
message by the other wireless transfer station, as in block
3430.
[0210] In one embodiment, the wireless transfer station can be
further configured to receive energy, at a wireless transfer coil
of the wireless transfer station from a wireless transfer coil of
the other wireless transfer station. In another embodiment, the
wireless transfer station can be further configured to determine
that the wireless transfer station is compatible to receive energy
from the other wireless charging using the wireless energy transfer
approval message. In another embodiment, the wireless transfer
station can be further configured to transfer wireless energy with
the other wireless transfer station on an energy channel and
communicate data between the wireless transfer station and the
other wireless transfer station using a communications channel. In
another embodiment, the wireless transfer station can be further
configured to communicate, to the other wireless transfer station,
authentication information on a first frequency channel and
transfer wireless energy with the other wireless transfer station
on a second frequency channel.
[0211] Another example provides functionality 3500 of product
including a non-transitory storage medium having stored thereon
instructions that are adapted to be executed to implement a method
of wirelessly transferring energy or data, as shown in the flow
chart in FIG. 35. The instructions of the product can be
implemented as a method or as instructions on a machine, where the
instructions are included on at least one computer readable medium
or one non-transitory machine readable storage medium. The method
can comprise receiving, from one or more wireless transfer station,
wireless transfer station identification (ID) messages, as in block
3510. The method can further comprise authenticating the wireless

least one of the one or more wireless transfer stations, as in
block 3520. The method can further comprise providing wireless
energy or data to the one or more wireless transfer stations based
on the permission level of the one or more wireless transfer
stations using one or more wireless transfer coils of the product,
as in block 3530.
[0212] In one embodiment, the method can further comprise receiving
a transfer request from a selected wireless transfer station of the
one or more wireless transfer stations and sending a transfer
approval message when the product authenticates the wireless
transfer station ID message of the one of the one or more wireless
transfer stations. In another embodiment, the method can further
comprise: receiving a transfer request from a plurality wireless
transfer stations of the one or more wireless transfer stations;

within an invalid wireless transfer station IDs below each of the
plurality of wireless transfer stations with valid for wireless
transfer station IDs for receiving a wireless transfer of energy or
data.
[0213] In one embodiment, the method can further comprise
determining when a wireless transfer station ID message for a
selected wireless transfer station of the one or more wireless
transfer stations is invalid based on the authentication of the
wireless transfer station ID message and creating a temporary

message to the selected wireless transfer station.
[0214] FIG. 36 provides an example illustration of the device, such
as a user equipment (UE), a mobile wireless device, a mobile
communication device, a tablet, a handset, or other type of
wireless device. The wireless device can include one or more
antennas configured to communicate with a wireless transfer
station. The device can be configured to communicate using at least

Speed Packet Access (HSPA), Bluetooth, and Wi-Fi. The device can
communicate using separate antennas for each wireless communication
standard or shared antennas for multiple wireless communication
standards. The device can communicate in a wireless local area
network (WLAN), a wireless personal area network (WPAN), and/or a
wireless wide area network (WWAN).
[0215] FIG. 36 also provides an illustration of a microphone and
one or more speakers that can be used for audio input and output
from the device. The display screen can be a liquid crystal display
(LCD) screen, or other type of display screen such as an organic
light emitting diode (OLED) display. The display screen can be
configured as a touch screen. The touch screen can use capacitive,
resistive, or another type of touch screen technology. An
application processor and a graphics processor can be coupled to
internal memory to provide processing and display capabilities. A
non-volatile memory port can also be used to provide data
input/output options to a user. The non-volatile memory port can
also be used to expand the memory capabilities of the device. A
keyboard can be integrated with the device or wirelessly connected
to the wireless device to provide additional user input. A virtual
keyboard can also be provided using the touch screen.
[0216] Various techniques, or certain aspects or portions thereof,
can take the form of program code (i.e., instructions) embodied in
tangible media, such as floppy diskettes, CD-ROMs, hard drives,
non-transitory computer readable storage medium, or any other
machine-readable storage medium wherein, when the program code is
loaded into and executed by a machine, such as a computer, the
machine becomes an apparatus for practicing the various techniques.
In the case of program code execution on programmable computers,
the computing device can include a processor, a storage medium
readable by the processor (including volatile and non-volatile
memory and/or storage elements), at least one input device, and at
least one output device. The volatile and non-volatile memory
and/or storage elements can be a RAM, EPROM, flash drive, optical
drive, magnetic hard drive, or other medium for storing electronic
data. The base station and mobile station can also include a
transceiver module, a counter module, a processing module, and/or a
clock module or timer module. One or more programs that can
implement or utilize the various techniques described herein can
use an application programming interface (API), reusable controls,
and the like. Such programs can be implemented in a high level
procedural or object oriented programming language to communicate
with a computer system. However, the program(s) can be implemented
in assembly or machine language, if desired. In any case, the
language can be a compiled or interpreted language, and combined
with hardware implementations.
[0217] It should be understood that many of the functional units
described in this specification have been labeled as modules, in
order to more particularly emphasize their implementation
independence. For example, a module can be implemented as a
hardware circuit comprising custom VLSI circuits or gate arrays,
off-the-shelf semiconductors such as logic chips, transistors, or
other discrete components. A module can also be implemented in
programmable hardware devices such as field programmable gate
arrays, programmable array logic, programmable logic devices or the
like.
[0218] Modules can also be implemented in software for execution by
various types of processors. An identified module of executable
code can, for instance, comprise one or more physical or logical
blocks of computer instructions, which can, for instance, be
organized as an object, procedure, or function. Nevertheless, the
executables of an identified module need not be physically located
together, but can comprise disparate instructions stored in
different locations which, when joined logically together, comprise
the module and achieve the stated purpose for the module.
[0219] Indeed, a module of executable code can be a single
instruction, or many instructions, and can even be distributed over
several different code segments, among different programs, and
across several memory devices. Similarly, operational data can be
identified and illustrated herein within modules, and can be
embodied in any suitable form and organized within any suitable
type of data structure. The operational data can be collected as a
single data set, or can be distributed over different locations
including over different storage devices, and can exist, at least
partially, merely as electronic signals on a system or network. The
modules can be passive or active, including agents operable to
perform desired functions.
[0220] Reference throughout this specification to "an example"
means that a particular feature, structure, or characteristic
described in connection with the example is included in at least
one embodiment of the present invention. Thus, appearances of the
phrases "in an example" in various places throughout this
specification are not necessarily all referring to the same
embodiment.
[0221] As used herein, a plurality of items, structural elements,
compositional elements, and/or materials can be presented in a
common list for convenience. However, these lists should be
construed as though each member of the list is individually
identified as a separate and unique member. Thus, no individual
member of such list should be construed as a de facto equivalent of
any other member of the same list solely based on their
presentation in a common group without indications to the contrary.
In addition, various embodiments and example of the present
invention can be referred to herein along with alternatives for the
various components thereof. It is understood that such embodiments,
examples, and alternatives are not to be construed as defacto
equivalents of one another, but are to be considered as separate
and autonomous representations of the present invention.
[0222] Furthermore, the described features, structures, or
characteristics can be combined in any suitable manner in one or
more embodiments. In the following description, numerous specific
details are provided, such as examples of layouts, distances,
network examples, etc., to provide a thorough understanding of
embodiments of the invention. One skilled in the relevant art will
recognize, however, that the invention can be practiced without one
or more of the specific details, or with other methods, components,
layouts, etc. In other instances, well-known structures, materials,
or operations are not shown or described in detail to avoid
obscuring aspects of the invention.
[0223] While the forgoing examples are illustrative of the
principles of the present invention in one or more particular
applications, it will be apparent to those of ordinary skill in the
art that numerous modifications in form, usage and details of
implementation can be made without the exercise of inventive
faculty, and without departing from the principles and concepts of
the invention. Accordingly, it is not intended that the invention
be limited, except as by the claims set forth below.
