Description
RELATED APPLICATION
[0001] This application claims the benefit of U.S. Patent
Application No. 61/093,163, filed Aug. 29, 2008.
TECHNICAL FIELD
[0002] The disclosure herein relates generally to power interfaces.
In particular, this disclosure relates to flexible power interfaces
for low-power devices such as cameras, display screens, security
panels, thermostats, sensors, etc.
BACKGROUND
[0003] Conventional battery backup systems have been used in many
forms, and some examples include security panels and
uninterruptable power supplies (UPS) for computers. The
conventional stand-alone UPS-type battery backup units are large,
however, and do not facilitate placement in the locations desirable
for devices such as video cameras.
[0004] In addition to conventional battery backup systems,
conventional transforniers for low-power devices such as video
cameras are also known in the art. The conventional transformers
for low-power devices also have shortcomings in that they are small
and do not include battery backup.
INCORPORATION BY REFERENCE
[0005] Each patent, patent application, and/or publication
mentioned in this specification is herein incorporated by reference
in its entirety to the same extent as if each individual patent,
patent application, and/or publication was specifically and
individually indicated to be incorporated by reference.

[0006] FIG. 1 is a conventional wall-powered transformer commonly
used with low-power devices on the market, under the prior art.
[0007] FIG. 2 is a block diagram of a power interface providing a
combination of battery-backup and low-power transformer, under an
embodiment.
[0008] FIG. 3 is a block diagram of a power interface providing a

DETAILED DESCRIPTION
[0010] A device or apparatus is described, referred to as a power
interface, that enables a low-power device (e.g., camera, etc.) to
be powered from an alternating current (AC) wall receptacle or
light socket with automatic backup battery charging. The power
interface of an embodiment comprises a transformer module that
receives an input signal. The device includes a battery module
coupled to the transformer module, and the battery module includes
battery charging circuitry coupled to a battery. The device
comprises an output controller coupled to the transformer module
and the battery module. The output controller includes detector
circuitry that detects a state of the input signal. The output
controller automatically controls coupling of one of a transformer
module output and a battery module output to a device output
according to the state of the input signal.
[0011] The power interface includes a combination of battery-backup
with low-power transformers that enable continuous operation of a
compact device during a power outage. Additionally, the power
interface of an embodiment provides the ability to connect a
compact device to an intermittent power supply so that when the
power is on the batteries charge and when the power is off the unit
continues to operate for as long as permitted by the batteries.
Furthermore, the power interface described herein provides the
ability to provide battery-backup features in any device to which
it is coupled without any modification being required to that
device.
[0012] The power interface is either directly plugged into an
electrical receptacle, or is connected to the receptacle using a
separate cable between the unit and the receptacle. The transformer
of the power interface operates or functions to step down the
incoming AC voltage and to regulate the incoming signal. Additional
circuitry of the power interface operates or functions to charge
the built-in battery pack during normal operation (e.g., external
AC power is on). If the external AC voltage is terminated or cut
off, additional circuitry in the power interface switches the
output of the transformer from receiving input or being fed from
the internal regulator to being fed from the built-in batteries,
thereby providing continuous and uninterrupted power to the coupled
device.
[0013] Moreover, in the case where the main power source is
switched (e.g., a device controlled by a wall switch, a light
controlled by a wall switch, etc.) the power interface of an
embodiment can control the state of the light through the user's
on-off action on the switch. In this way, the battery inside the
power interface can continue charging even if the user desires the
light to be off.
[0014] The power interface described herein can be used, for
example, with components of an integrated security system like any
of those described in any of U.S. patent application Ser. Nos.
12/269,585, 12/197,895, 12/198,023, 12/189,757, 12/019,554,
12/019,568, 11/761,718, 11/761,745, and 11/084,232. The integrated
security system described in these applications is available from
iControl Networks, Inc. of Palo Alto, Calif.
[0015] In the following description, numerous specific details are
introduced to provide a thorough understanding of, and enabling
description for, the systems and methods described. One skilled in
the relevant art, however, will recognize that these embodiments
can be practiced without one or more of the specific details, or
with other components, systems, etc. In other instances, well known
structures or operations are not shown, or are not described in
detail, to avoid obscuring aspects of the disclosed
embodiments.
[0016] FIG. 1 is a conventional electrical transformer 100
typically used with low-power devices, under the prior art. The
transformer is either directly plugged into an electrical
receptacle or outlet in the wall ("receptacle"), or is connected to
the receptacle using a separate cable between the unit and the
receptacle. In either case, the conventional transformer first
converts the 110/220 volt (V) alternating current (AC) voltage to a
lower AC voltage level suitable for the device being powered.
Depending on the requirements of the device, this low voltage AC is
either directly cabled to the device, or is converted to a direct
current (DC) voltage by the transformer before being cabled.
[0017] FIG. 2 is a block diagram of a power interface 200 that
provides a combination of battery-backup and low-power
transforming, under an embodiment. The circuitry of the power
interface 200 integrates battery backup functionality with the
functionality of an electrical transformer and regulator. The power
interface 200 of an embodiment is coupled or connected to an input
signal 201. The input signal 201, for example, is an electrical
signal such that the power interface is powered from an AC
electrical source (e.g., wall receptacle, light socket, etc.).
[0018] The power interface 200 comprises a transformer module 210
that receives the input signal. The power interface 200 includes a
battery module 220 coupled to the transformer module 210, and the
battery module 220 includes battery charging circuitry 222 coupled
to a battery 224. The power interface 200 comprises an output
controller 230 coupled to the transformer module 210 and the
battery module 220. The output controller 230 includes detector
circuitry 232 that detects a state of the input signal, and
selector circuitry 234 for controlling an output 250 of the power
interface 200.
[0019] The transformer module 210 of the power interface 200
comprises transformer circuitry 212 that receives the input signal
201. The transformer circuitry 212 includes a step-down transformer
that reduces a voltage of the input signal, but is not so limited.
The transformer module 210 of an embodiment also includes regulator
circuitry 214 coupled to the transformer circuitry 212. The
regulator circuitry 214 functions to regulate the input signal as
appropriate to a type and condition of the input signal and or an
output signal. The transformer module 210 can include converter
circuitry (not shown) to convert the input signal between AC and DC
signal types, as appropriate. Additionally, the transformer module
210 can include other circuitry (e.g., filters, etc.) (not shown)
as appropriate to the input signal and/or a device to which the
power interface is coupled.
[0020] An output of the regulator circuitry 214 is coupled to the
detector circuitry 232 and a selector 234 of the output controller
230. Additionally, an output of the regulator circuitry 214 is
coupled to the battery charging circuitry 222 of the battery module
220. An output of the battery module 220 is coupled to the selector
circuitry 234 of the output controller 230.
[0021] The output controller 230 automatically controls coupling of
an output of one of the transformer module 210 and the battery
module 220 to a device output 250 according to the state of the
input signal detected by the detector circuitry 232. As an example,
the selector 234 of the output controller 230 automatically couples
the output of the transformer module 210 to the output 250 of the
device when the state of the input signal is present. Further, when
the state of the input signal is present, the battery charging
circuitry 222 charges the battery 224. The selector 234 of the
output controller 230 automatically couples the output of the
battery module 220 to the output of the device when the state of
the input signal is absent.
[0022] While the input signal 201 of the power interface of an
embodiment is an AC signal, the device output 250 can be an AC
signal and/or a DC signal. For example, AC-to-DC converter
circuitry or DC-to-AC converter circuitry can be included in the
power interface signal path, as appropriate, to provide the desired
type of output signal. Alternatively, the power interface 200 of an
embodiment provides both AC output signals and DC output signals
using converter circuitry appropriate to both AC and DC output
signals.
[0023] The power interface of an embodiment can have any number of
form factors under the disclosure herein. For example, the power
interface can be packaged as a separate device having input and
output cables or receptacles. As another example, the power
interface can be included or integrated as a component or subsystem
of a host system to which it provides power.
[0024] As yet another example, the power interface can have a form
factor for use in a particular application. FIG. 3 is a block
diagram of a power interface 300 providing a combination of
battery-backup and low-power transformation in a light socket
adapter, under an alternative embodiment. The light socket adapter
form factor is suitable for use in locations where an electrical
receptacle is not available or a light fixture with a light socket
is more convenient or closer to the device than an electrical
receptacle.
[0025] The power interface 300 of this embodiment is housed in a
light socket adapter, where the light socket adapter screws into a
conventional electrical light socket 360. The light socket adapter
housing includes a receptacle for receiving a conventional screw-in
light bulb 370. The power interface 300 of this embodiment is
coupled or connected to an input signal 301 via coupling with the
electrical light socket 360 such that the input signal 301 is an
electrical signal received via the electrical terminals of the
light socket 360.
[0026] The circuitry of the power interface 300 housed in the light
socket adapter is shown and described with reference to FIG. 2
above. The power interface 300 comprises a transformer module that
receives the input signal. The power interface 300 includes a
battery module coupled to the transformer module, and the battery
module includes battery charging circuitry coupled to a battery.
The power interface 300 comprises an output controller coupled to
the transformer module and the battery module. The output
controller includes detector circuitry that detects a state of the
input signal, and selector circuitry for controlling an output 350
of the power interface 300.
[0027] The transformer module of the power interface 300 comprises
transformer circuitry that receives the input signal. The
transformer circuitry includes a step-down transformer that reduces
a voltage of the input signal, but is not so limited. The
transformer module of an embodiment also includes regulator
circuitry coupled to the transformer circuitry. The regulator
circuitry functions to regulate the input signal as appropriate to
a type and condition of the input signal and or an output signal.
The transformer module can include converter circuitry (not shown)
to convert the input signal between AC and DC signal types, as
appropriate. Additionally, the transformer module can include other
circuitry (e.g., filters, etc.) (not shown) as appropriate to the
input signal and/or a device to which the power interface is
coupled.
[0028] An output of the regulator circuitry is coupled to the
detector circuitry and a selector of the output controller.
Additionally, an output of the regulator circuitry is coupled to
the battery charging circuitry of the battery module. An output of
the battery module is coupled to the selector circuitry of the
output controller.
[0029] The output controller automatically controls coupling of an
output of one of the transformer module and the battery module to a
device output according to the state of the input signal detected
by the detector circuitry. As an example, the selector of the
output controller automatically couples the output of the
transformer module to the output of the device when the state of
the input signal is present. Further, when the state of the input
signal is present, the battery charging circuitry charges the
battery. The selector of the output controller automatically
couples the output of the battery module to the output of the
device when the state of the input signal is absent.
[0030] In this embodiment, a potential problem may arise if the
light socket is controlled via a light switch (e.g., patio light
being controlled by a light switch from inside the house). Thus,
the light socket adapter power interface includes circuitry that
allows the host light to be off without having to physically turn
off the power to the light socket. For example, if the external
switch is turned "OFF" and then "ON" quickly (e.g., within 1
second) then circuitry of the socket transformer interprets that
switching activity and deactivates or turns the light off.
[0031] FIG. 4 is a flow diagram for controlling 400 power output of
a device, under an embodiment. The controlling comprises receiving
an input signal at a device, and generating a first output signal
by transforming the input signal 402. The transforming comprises at
least one of reducing a voltage of the input signal and regulating
the voltage of the input signal. The controlling comprises charging
a battery of the device with the first output signal 404. The
controlling comprises providing a second output signal that is an
output of the battery 406. The controlling comprises detecting a

first output signal and the second output signal according to the
state of the input signal 410. The automatic controlling comprises

the state of the input signal is present. Additionally, the
charging of the battery occurs when the state of the input signal
is present. The automatic controlling comprises coupling the second
output signal to the output of the device when the state of the
input signal is absent.
