Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims priority to and the benefit
of U.S. Provisional Patent Applications Nos. 61/734,848 and
61/793,319 filed on Dec. 7, 2012 and March 15, 2013, respectively.
The foregoing provisional applications are incorporated by
reference herein in their entireties.
BACKGROUND
[0002] The present application relates generally to the field of
wireless communication systems between an electronic device and a
fixed communications network. An electronic device may include, for
example, a cell phone, smart phone, PDA, tablet computer, laptop
computer, e-reader, and handheld video game.
[0003] The increased use of electronic devices, particularly mobile
communications devices, currently allows for continuous
communication, entertainment, and the transfer of information from
nearly any location. As a result, many individuals carry such
electronic devices in direct physical proximity to their bodies
throughout the day.
[0004] Various systems and methods to electromagnetically couple or
"pair" a handheld electronic device with a fixed communication
network (e.g., a vehicle communication bus) are known in the art.
Further, some systems may automatically detect an electronic
device, and enable its "hands-free" application use. Such systems
may require a user to perform an initial setup process between the
fixed communication network and the electronic device (e.g., a
setup process may identify a particular electronic device by using
a serial code, mobile equipment identifier (MEID), or similar
identifier). Further, each new user, and each additional device may
be required to undergo an initial setup process.
[0005] Such systems that automatically electromagnetically couple
an electronic device may also require that the user has enabled
automated pairing between the device and a network. Automated
pairing between an electronic device and a network may use an
electronic information exchange paradigm, such as Bluetooth or
Wifi. Further, a fixed communications network may initiate a
pairing process, and detect every electronic device enabled to
communicate within the selected communication paradigm (e.g.,
Bluetooth, Wifi) independent of the location of the user or the
device. Therefore, current pairing techniques may not independently
identify the physical location of the user or the device.
[0006] In some situations, there may be a need to control an
electronic device based on the location of the user or the device.
For example, federal laws and regulations restrict the use of an
electronic device on an airplane. Therefore, in accordance with
such laws, a system or method may be used to control the use of an
electronic device on an airplane.
[0007] In addition, a person who is driving a vehicle or operating
a machine may be impaired by their concurrent use of an electronic
device. Therefore, in order to prevent a vehicular accident, a
system or method may be used to control an electronic device based
on the actual physical location of either the person or the
device.
[0008] Various systems and methods that estimate, or determine the
proximate location of a device are known in the art. For example,
GPS and/or cellular network triangulation may indicate that an
electronic device is in motion, and cooperatively-loaded
application software on the electronic device may control handheld
use of the device. However, these systems and methods cannot
distinguish whether the electronic device is in the possession of a
driver or a passenger. Therefore, a passenger of a vehicle (i.e.,
someone other than the driver), whose use of an electronic device
is not impaired from operating a vehicle, may have to manually
bypass a system or method used to control the electronic
device.
[0009] Further, various systems or methods used to control an
electronic device may not distinguish between different modes of
transportation. For example, while it may be desired to control the
use of an electronic device by a driver of a vehicle, the same
electronic device may not need to be controlled for use on public
transportation (e.g., train, bus, taxi, etc.).
[0010] In an alternative system, a wireless transmitter for a fixed
communications network, such as a vehicle communication bus, may
transmit a signal to an electronic device that includes information
relating to a condition of a network. In the case of a vehicle, the
information in a signal may include whether the vehicle is in
motion or in gear. Cooperatively loaded application software on an
electronic device may detect the signal from the fixed
communications network. Depending on the information included in
the signal, the application software may control various features
of the electronic device. For example, cooperatively loaded
application software on the electronic device may use information
from a signal to limit the handheld use of the device, or to
provide cellular notification to back-end services (e.g., speed
alerts).
[0011] A system or method for automated network pairing using
electric field coupling may require an electronic device to include
hardware that can receive or transmit a signal to the fixed
communications network. A system or method for automated network
pairing using electric field coupling may also require software to
interface with the fixed communications network or detect a signal
transmitted by the fixed communications network. Such an electronic
device that is in proximity to detect a signal transmitted by the
network may be controlled by the cooperatively installed software
on the device.
[0012] A system or method to that can detect, electronically couple
with, and control an electronic device may not distinguish between
a device used by an intended user (i.e., a driver of a vehicle) and
an unintended user (i.e., a passenger of a vehicle). Further, an
unintended user may be required to manually bypass the system or
method to control an electronic device. Therefore, an object of the
present disclosure is a system or method to control an electronic
device used by a particular user or in a particular location.
SUMMARY
[0013] According to an exemplary embodiment of this disclosure, a
system to electronically couple an electronic device to a network
may include a sensing electrode that provides a signal. The signal
provided by the sensing electrode may have a particular frequency
and power, and the electrode may be configured to transmit the
signal through a person occupying a proscribed location. The
electronic device may be configured to detect the signal when the
electronic device is coupled to a person occupying the proscribed
location, and when the device detects the signal it may be
configured to electronically couple to the network upon detecting
the signal.
[0014] According to an alternative embodiment of the disclosure, a
system to electronically couple an electronic device to a network
may include a sensing electrode that provides a signal. The signal
may have a particular frequency and power, and the sensing
electrode may be configured to transmit the signal to the
electronic device when the electronic device is positioned in a
proscribed location. The electronic device may be configured to
detect the signal when the second electronic device is either
positioned in the proscribed location, and when the electronic
device detects the signal, the electronic device may be configured
to electronically couple to the network.
[0015] According to yet another alternative embodiment of the
disclosure, a method for electronically coupling an electronic
device to a network using electric field coupling may include
several steps. For example, a method may transmit an electronic
signal from a sensing electrode to a person occupying a proscribed
location and coupled to the second electronic device. Based upon
detection of the signal by the electronic device, a method may
electronically couple the electronic device to the network. The
signal may be configured to be redistributed through a person via
electronic field coupling, and the electronic device may be coupled
to the person in order to electronically couple to the network.

DETAILED DESCRIPTION
[0021] Various embodiments of the present disclosure will be
described below with reference to the drawings. It is to be
understood that both the foregoing general description and the
following detailed description are exemplary and explanatory only,
and are not restrictive of the disclosure.
[0022] According to an exemplary embodiment, a system and method
may identify and establish a communication paradigm between a fixed
network and an electronic device in which the communication medium
is through the human body.
[0023] A system proposed herein may dependently associate the
physical presence (e.g., held in hand, in pocket, etc.) of an
occupant with a location of the electronic device (e.g., vehicle
seating location). Such a system may allow one-way or two-way
communication between a fixed network and the electronic device,
and through an occupant, in order to dependently establish
control/communication parameters of the device, as well as software
application activation, based on a specified position of the
device.
[0024] As shown in FIG. 1, and according to an exemplary
embodiment, an electric field coupling network 11 may be used to
electronically couple or pair a fixed communications network, such
as a vehicle communications bus 6, with an electronic device 1. A
driver 3 of a vehicle 12 may be seated on a vehicle seat 4, and an
electronic device 1 may be coupled to the driver (e.g., an
electronic device 1 may be held in the hand of the driver 3, in a
pocket of the driver's clothes, or in any other location that is
sufficiently proximate to the driver). A system 13 used to
electronically couple an electronic device to a network may include
a capacitive sensor pad 2 provided in a vehicle seat 4 within a
vehicle 12. While sensor pad 2 may be provided in a driver's seat 4
of a vehicle, this disclosure is not intended to limit the possible
locations in which a sensor pad may be located. Therefore,
according to alternative embodiments of this disclosure, a sensor
pad could be located anywhere in a vehicle interior (i.e. in a
passenger seat, the vehicle floor, an arm rest, the steering wheel,
a cup holder, etc.).
[0025] Referring to FIGS. 1-3, and according to various embodiments
of this disclosure, a sensing electrode, which may be configured as
a sensor pad 2, may be able to detect the presence or occupancy of
a person or object that is positioned within a proscribed location.
Further, sensor pad 2 may be configured to detect various
characteristics of an object, such as its position on a seat.
Sensor pad 2 may also be configured to discriminate or categorize
the object (e.g., person, baby seat, shopping bag, etc.), and to
detect other characteristics of the object (e.g., stature,
position, loading, etc.). In addition, sensor pad 2 may be provided
as a component of another system, such as an occupant detection or
classification system.
[0026] Referring to FIGS. 1-3, and according to various embodiments
of this disclosure, a system 13 may also be configured to transmit
a signal 11 to a conductor in the sensor pad 2 and through a person
positioned within a proscribed location. When the system is used
for occupant sensing a sensing circuit may be provided for signal
generation and occupant sensing. Alternatively, a separate control
unit including a signal generator may be provided. The signal
generator provides a signal, e.g., a sinusoidal signal, to an
electrode in the seat or floor or other location proximate to the
person. For instance, the transmitted signal 11 may have a
particular frequency and power, and the frequency of the
transmitted signal 11 may be configured to allow it to be
redistributed through the person via electric field coupling when
the person is positioned within a proscribed location. Such a
signal may be configured so that it is not strong enough to be
transmitted through the air surrounding a person positioned within
a proscribed location.
[0027] According to an exemplary embodiment shown in FIG. 1, sensor
pad 2 may transmit a signal 11, which may be configured to be
redistributed via electric field coupling through driver 3 that is
sitting on seat 4. According to an alternative embodiment shown in
FIG. 2, a sensor pad may be disposed within a floor, be configured
to transmit a signal 11 to a person 3, who is standing over sensor
pad 2. The transmitted signal 11 may be configured to be
redistributed through person 3 via electric field coupling.
[0028] Sensor pad 2 may also be electronically coupled to support
electronics 5 which may be configured to measure the amount of
electric field coupling between sensor pad 2 and objects proximate
the sensor pad. According to an exemplary embodiment shown in FIG.
1, the support electronics 5 may be, in turn, electronically
coupled to a vehicle communication bus 6. The support electronics
may include at least one integrated circuit, discrete electronic
components, printed circuit board, or microprocessor, for example.
The capacitive sensing subsystem employed with the system may be
similar to the systems disclosed in U.S. Pat. No. 6,392,542 and
U.S. Published Patent Application No. 2007/0200721 (both
incorporated by reference herein).
[0029] As shown in FIG. 1, and according to various exemplary
embodiments of this disclosure, an electronic device 1 may be
configured to detect the transmitted signal 11 when the signal 11
is transmitted through a person, and the electronic device 1 is
coupled to the person. According to the embodiment shown in FIG. 1,
an electronic device 1 may be configured to detect the transmitted
signal 11 when electronic device 1 is positioned within a
proscribed location, such as the driver's seat of a vehicle. The
detection of the signal may be conducted utilizing a tuning circuit
located in the electronic device. Exemplary tuning circuits are
disclosed, for example, in U.S. Published Patent Application No.
2011/0117863. The foregoing published patent application is
incorporated by reference herein.
[0030] Further, when an electronic device detects the transmitted
signal 11, a response of the device may be to electronically
couple, or interface, with a fixed communications network, such as
a vehicle communication bus 6. An electronic device 1 may also
include hardware and/or software to facilitate or control the
coupling of the electronic device to a fixed communications
network.
[0031] According to an exemplary embodiment, the transmitted signal
11 may be configured to carry particular information used to
distinguish it from other signals, such as digital or analog
information. Further, the power of the transmitted signal 11 may be
configured to be sufficiently strong to be transmitted through a
person who is coupled to an electric field generated around the
signal carrying sensing electrode, but not sufficient to be
transmitted from the person's body. Therefore, an electronic device
may be configured to detect the signal 11 only when the person is
concurrently coupled to the electronic device and the electric
field. When the electronic device detects the signal 11, it may
distinguish the signal based on the information contained in the
signal.
[0032] According to an exemplary embodiment, upon detection of the
signal 11, the electronic device 1 may initiate a pairing process
with a fixed communications network in which the electronic device
1 automatically connects to the network. A pairing process may be
accomplished in a variety of ways. For example, in order to ensure
the security of the connection, the electronic device 1 may
initiate the pairing process by transmitting a wireless signal to
the network. In order for the network to distinguish the signal
transmitted from the electronic device 1, and to ensure the
security of the connection between the device and the network, the
signal may be configured to have a particular frequency or to carry
particular information. The electronic device 1 and the network may
perform a variety of processes in order to maintain security
therebetween. For example, the device and network may be
time-synced and the network may use an algorithm to determine a
random frequency pattern that is shared with the electronic device
1. While some examples have been described in which an electronic
device may automatically connect with a fixed network, it should be
understood that the electronic device 1 disclosed herein may
perform a variety of methods in order to connect to a fixed
communications network, according to other exemplary
embodiments.
[0033] According to an exemplary embodiment, the fixed
communication network may also initiate a pairing process in order
to connect to the electronic device 1. For example, the network may
continuously transmit a wireless signal to a surrounding area.
Alternatively, the network may transmit a wireless signal to a
surrounding area when a person is detected within a proscribed
location (e.g., a proscribed location may be proximate a sensing
electrode that transmits a capacitive signal). The wireless signal
transmitted from the network may use an authorization or
identification process establish a secure connection with an
electronic device. Such an identification process may require the
electronic device 1 to transmit a signal having particular
information to the network. Concurrently, the electronic device 1
may be coupled to a capacitive signal that is transmitted from a
proscribed location, and the signal may contain particular
information. When the electronic device detects the capacitive
signal, it may use the particular information contained within the
capacitive signal to satisfy the network's authorization or
identification process. In order to maintain a secure connection,
the electronic device 1 and the network may be time-synced and the
network may use an algorithm to determine a random frequency
pattern that is shared with the electronic device 1. While some
examples have been described in which a network may automatically
connect with the electronic device 1, it should be understood that
the network and the electronic device 1 disclosed herein may
perform a variety of methods in order to automatically establish a
connection, according to other exemplary embodiments.
[0034] Referring now to FIG. 2, an alternative exemplary embodiment
is shown for a system that may use electric field coupling to
automatically connect to a network. The system may include a
capacitive sensor pad 2 proximate to a standing person 3 (e.g. the
sensor pad may be embedded in a floor). A sensor pad may be
positioned so that a person 3 standing thereon is within proximity
of a human machine interface (HMI) device (e.g., audio, video.
tactile, etc.). The sensor pad shown in FIG. 2 may transmit a
signal 11 having a capacitively coupled frequency. In other words,
the transmitted signal 11 may be configured to be redistributed
through a person 3 via electric field coupling. When person 3 is
positioned within sufficient proximity of a sensor pad 2, an
electronic device 1 coupled to person 3 may be electronically
coupled to a fixed communications network, such as a HMI device,
and any network that is simultaneously electronically coupled to
the fixed communications network. Information may be exchanged
among each of these networks when electronic device 1 is
electronically coupled to a fixed communications network or other
network.
[0035] Referring now to FIG. 3, an alternative embodiment is shown
for a system that may be implemented in a particular seating
configuration in which a seat is positioned behind another seat.
Such a seating configuration may be used, for example, within a
bus, train, or airplane. A capacitive sensor pad 2 may be mounted
within a seat 4 that is configured according to the arrangement
shown in FIG. 3. Further, a fixed communications network, such as a
human machine interface (HMI) device 10 (e.g., audio, video,
tactile, etc.) shown in FIG. 3 may be positioned on a rear facing
surface of an adjacent seat, compartment wall, or bulkhead. Sensor
pad 2 may be configured to transmit a signal 11 through a person 3
who is seated on seat 4. An electronic device 1 coupled to person 3
may be configured to detect the transmitted signal 11, and
electronically couple to HMI device 10. Therefore, when person 3 is
occupied within a particular location proximate a HMI device, a
communication state may be established between an device 1, the HMI
device, and any wired network 14 or wireless network 15 that is
electronically coupled to the HMI device. Such a system may be used
to facilitate the exchange of information between sensor pad 2,
electronic device 1, and HMI device 10.
[0036] According to an exemplary embodiment shown in FIG. 4, an
electronic device 1 may include a communication module 9 and a
tuned circuit 8. Communication module 9 may include several
sub-modules configured to detect, filter, modulate, or demodulate
signals, including wireless digital or analog signals.
Communication module 9 may also include a digital signal processor,
among other components. A tuned circuit 8 may be coupled to a
component of an electronic device 1, such as an outer casing 7 or a
tuned antenna. The tuned circuit 8 may be configured to detect a
signal 11 having a capacitive coupled frequency (e.g.,
approximately 200 Khz) when the device is in contact with or
proximate to a person's body (e.g., finger, hand, skin in proximity
to a pocket, waistbelt, etc.). While a signal 11 having a frequency
of approximately 200 Khz is suggested, this is not intended to
limit the scope of this disclosure or the range of possible
frequencies that may be used be transmitted through a person or to
an electronic device via electric field coupling.
[0037] According to yet another embodiment of this disclosure, a
method to electronically couple an electronic device to a fixed
communication network may transmit an electronic signal from a
sensing electrode to a person occupying a proscribed location and
coupled to the electronic device. Based upon detection of the
signal by the electronic device, the electronic device may
electronically couple the electronic device to the network. In such
a method, the signal may be configured to be redistributed through
a person via electronic field coupling. Further, the electronic
device may have to be coupled to the person in order to detect the
signal.
[0038] In summary, a system or method may use electric field
coupling to electronically couple or "pair" an electronic device 1
with a network may generate a signal having a capacitive coupled
frequency. For example, an electrode in a capacitive sensing
subsystem may transmit a signal having a capacitive coupled
frequency. The signal may be configured to be transmitted across a
person who is sufficiently proximate to an electrode or sensing pad
generating the signal. A tuned circuit 8 of an electronic device 1
that is sufficiently proximate to the person's body may detect the
signal having a capacitive coupled frequency. An electronic device
1 may be configured to detect a signal having a capacitive coupled
frequency, and either a communication module 9 or the electronic
device 1 may be configured to automatically pair with a network
that is electronically coupled to the capacitive sensing
subsystem.
[0039] A sensor pad and supporting electronics may cooperate with
hardware and software added to an electronic device to detect the
location and possession of the device. According to an exemplary
embodiment, when an electronic device is detected in a particular
location, this information may be used, for example, to disable the
use of an electronic device in possession of the driver while the
vehicle is operational. In a similar fashion, a system may be
configured to detect and control an electronic device 1 that is
placed on an unoccupied seat (e.g., when a driver places a cell
phone on an empty passenger seat).
[0040] According to alternative embodiments of this disclosure, a
sensor pad may be incorporated into various other vehicle
compartments. For example, a sensor pad may be embedded in a
cup-holder, a phone receptacle or another location where an
electronic device may be placed. According to an alternative
embodiment, a sensor pad 2 may be located in a passenger seat, and
configured to generate a signal 11 having a capacitive coupled
frequency. An electronic device 1 may detect the transmitted signal
11 via electronic field coupling when the device is placed on the
seat, or when the device is otherwise within sufficient proximity
of the transmitted signal 11. When electronic device 1 detects the
transmitted signal 11, various hardware or software of electronic
device 1 may automatically control its use while the vehicle is in
motion. Also, hardware or software of electronic device 1 may
electronically couple or "pair" the device with a vehicle
communication bus 6 and enable hands-free technology.
[0041] According to alternative embodiments of this disclosure, a
system to electronically couple an electronic device and a fixed
communications network may be utilized in a wide variety of
locations, including personal and public transportation vehicles,
homes, schools, business locations, and other venues.
Advantageously, several personalized and selectable communications
modes, which are based on the physical location of an electronic
device, may exist for particular systems used to electronically
couple an electronic device and a fixed communications network. may
be configured to operate in the system may include personalized,
selectable communication modes based on physical locations (e.g., a
car driver mode, a car passenger mode, a bus mode, a plane mode, a
train mode, a theater mode, etc.) where the characteristics of the
automated network would be set based on mode (e.g., cell phone
ringer disabled in movie theater; hands-free enabled in car driver
seat; music/video playback enabled in bus, infotainment system
enabled in a plane seat back, etc.).
[0042] Advantageously, according to various embodiments of this
disclosure, a system 13 may allow a single fixed communications
network, such as a HMI, to be customizable by a specific human
touch by allowing a user interface to function differently for
multiple proximal occupants. In other words, a HMI may distinguish
between a person who is positioned within a particular location,
and a person positioned in an alternative location. For example, an
HMI in the form of a dash-mounted touch screen in a vehicle may be
configured to function in a first manner with respect to a driver
of the vehicle, and in a second manner for a passenger of the
vehicle.
[0043] A system 13 may be configured so that the electric field
characteristics of the sensor pad change from a first configuration
(i.e., a normal operating configuration) to a second configuration
when a vehicle event occurs. A signal having a second configuration
may enable an alternative means of network communications between
an electronic device 1 and a fixed communications network. For
example, if a vehicle experiences an event, such as a vehicle
collision, or a roll-over, sensor pad 2 may transmit a signal
having a second configuration which all electronic devices within
the vehicle compartment may be configured to detect. When an
electronic device detects a signal having a second configuration,
the device may be configured to automatically initiate an emergency
phone call.
[0044] Advantageously, one skilled in the art will appreciate that
a system may be configured to provide enhanced security when
electronically coupling to an electronic device by dependently
relying on occupancy or physical possession of a particular device.
Further, additional security may be provided, in addition to other
limitations, such as requiring a password, an encryption, and other
wireless connectivity limitations.
[0045] For purposes of this disclosure, the term "coupled" means
the joining of two components (electrical, mechanical, or magnetic)
directly or indirectly to one another. Such joining may be
stationary in nature or movable in nature. Such joining may be
achieved with the two components (electrical or mechanical) and any
additional intermediate members being integrally defined as a
single unitary body with one another or with the two components or
the two components and any additional member being attached to one
another. Such joining may be permanent in nature or alternatively
may be removable or releasable in nature.
[0046] The present disclosure has been described with reference to
example embodiments, however persons skilled in the art will
recognize that changes may be made in form and detail without
departing from the spirit and scope of the disclosed subject
matter. For example, although different example embodiments may
have been described as including one or more features providing one
or more benefits, it is contemplated that the described features
may be interchanged with one another or alternatively be combined
with one another in the described example embodiments or in other
alternative embodiments. Because the technology of the present
disclosure is relatively complex, not all changes in the technology
are foreseeable. The present disclosure described with reference to
the exemplary embodiments is manifestly intended to be as broad as
possible. For example, unless specifically otherwise noted, the
exemplary embodiments reciting a single particular element also
encompass a plurality of such particular elements.
[0047] Exemplary embodiments may include program products
comprising computer or machine-readable media for carrying or
having machine-executable instructions or data structures stored
thereon. For example, the sensing electrode may be computer driven.
Exemplary embodiments illustrated in the methods of the figures may
be controlled by program products comprising computer or
machine-readable media for carrying or having machine-executable
instructions or data structures stored thereon. Such computer or
machine-readable media can be any available media which can be
accessed by a general purpose or special purpose computer or other
machine with a processor. By way of example, such computer or
machine-readable media can comprise RAM, ROM, EPROM, EEPROM, CD-ROM
or other optical disk storage, magnetic disk storage or other
magnetic storage devices, or any other medium which can be used to
carry or store desired program code in the form of
machine-executable instructions or data structures and which can be
accessed by a general purpose or special purpose computer or other
machine with a processor. Combinations of the above are also
included within the scope of computer or machine-readable media.
Computer or machine-executable instructions comprise, for example,
instructions and data which cause a general purpose computer,
special purpose computer, or special purpose processing machines to
perform a certain function or group of functions. Software
implementations of the present disclosure could be accomplished
with standard programming techniques with rule based logic and
other logic to accomplish the various connection steps, processing
steps, comparison steps and decision steps.
[0048] It is also important to note that the construction and
arrangement of the elements of the system as shown in the preferred
and other exemplary embodiments is illustrative only. Although only
a certain number of embodiments have been described in detail in
this disclosure, those skilled in the art who review this
disclosure will readily appreciate that many modifications are
possible (e.g., variations in sizes, dimensions, structures, shapes
and proportions of the various elements, values of parameters,
mounting arrangements, use of materials, colors, orientations,
etc.) without materially departing from the novel teachings and
advantages of the subject matter recited. For example, elements
shown as integrally formed may be constructed of multiple parts or
elements shown as multiple parts may be integrally formed, the
operation of the assemblies may be reversed or otherwise varied,
the length or width of the structures and/or members or connectors
or other elements of the system may be varied, the nature or number
of adjustment or attachment positions provided between the elements
may be varied. It should be noted that the elements and/or
assemblies of the system may be constructed from any of a wide
variety of materials that provide sufficient strength or
durability. Accordingly, all such modifications are intended to be
included within the scope of the present disclosure. The order or
sequence of any process or method steps may be varied or
re-sequenced according to alternative embodiments. Other
substitutions, modifications, changes and omissions may be made in
the design, operating conditions and arrangement of the preferred
and other exemplary embodiments without departing from the spirit
of the present subject matter.
