Responsive to the power management schedule, a power management controller dynamically controls a level of power for the server.

A low cost, robust, repeater for a wireless ambient sensor system that provides an extended period of operability without maintenance is described. The repeater includes a controller and first and second transceivers. The controller is configured to control operation of said first transceiver and said second transceiver. The wireless repeater includes a repeater identification. The controller is configured to manage a sensor unit identification table that contains a list of sensor unit identification codes, where entries for the sensor unit identification table are received by the second transceiver from the base unit and identified by the repeater identification. The controller controls the first transceiver and the second transceiver to forward data from sensor units listed in said sensor unit identification table and to ignore data from sensor units not listed in said sensor unit identification table.

Systems and methods for processing motion sensor data using various power management modes of an electronic device are provided. Power may be provided to a motion sensor during a first power mode of the device. In response to the motion sensor detecting a motion event with a magnitude exceeding a threshold, the sensor may transmit a wake up signal to a power management unit of the device.

The device may provide power to a processor and load the processor with a motion sensing application when switching to the second power mode. During the second power mode, motion sensor data may be processed to determine that the motion event is not associated with an intentional user input and the device may return to the first power mode.

A system for load control in an electrical power system is described, wherein one or more load-control devices are provided to control power delivered to electrical equipment. A remote power authority, such as a power company, government agency, or power transmission company sends one or more commands to the load-control devices to adjust loading on the electrical power system. In one embodiment, the power authority sends shutdown commands. In one embodiment, the power authority sends commands to tell the electric power device to operate in a relatively low-power mode. In one embodiment, the commands are time-limited, thereby allowing the electric power device system to resume normal operation after a specified period of time. In one embodiment, the commands include query commands to cause the control device to report operating characteristics (e.g., efficiency, time of operation, etc.) back to the power authority.

Devices and methods of detecting a predetermined audio signal in audio signals are provided. A device includes a processor coupled to a clock signal generator, a power controller and an audio detector. The power controller controls a clock rate provided to the processor by the clock signal generator, to control the device to operate in a low power mode having a relatively low power consumption or in a normal power mode having a relatively high power consumption. The audio detector receives audio signals and detects, in the low power mode, probable presence of a predetermined audio signal in the audio signals. The power controller controls the device to switch from the low power mode to the normal power mode responsive to the detected presence of the predetermined audio signal by the audio detector.

A wireless local area network (WLAN) includes an access point (102) and a mobile station (106). The mobile station can operate in a low power mode by shutting down a WLAN subsystem (204) of the mobile station. While the mobile station is in a low power mode, the access point buffers data received at the access point destined for the mobile station (706). The mobile station wakes up to initiate a service period by transmitting a trigger frame to the access point, and identifies a traffic stream to be serviced in the presently initiated service period. The access point begins transmitting response frames to the mobile station, identifying the traffic stream requested by the mobile station, and in at least one response frame, the access point may indicate the buffer status of another traffic stream associated with the mobile station to allow the mobile station to make decisions regarding data retrieval and power save state.

A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so.

A wireless device including a transceiver that utilizes a power supply is described. The wireless device includes a Global Positioning System (“GPS”) section having a plurality of GPS subsystems and a power controller in signal communication with the power supply and GPS section, wherein the power controller is configured to selectively power each GPS subsystem from the plurality of GPS subsystems.

An identification system, e.g. for tagging goods in a retail store, has at least one interrogator and a number of transponders for attaching to goods. Each transponder responds to an interrogation signal from the interrogator by returning a response signal containing information stored in the transponder. The transponder can be switched, by means of a mode switching signal from the interrogator, into a reduced power mode in which the power level of the response signal is reduced from its normal level. The reduced power mode may for example be selected when the goods have been paid for, to ensure that the transponder does not trigger an anti-theft gate, which can detect only the normal power level. The transponder can, however, still be read by an interrogator capable of detecting the reduced power level, e.g. at a customer services desk.

A portable computing device includes a keyboard controller that receives keystroke information as well as inputs from a graphical pointing device and conveys these to a main central processing unit. The keyboard controller additionally communicates with a battery module through a second interface in order to monitor and control the charging of the module. A low power secondary processor is interfaced to the keyboard controller through the second interface in order to receive keystroke information as well as information from the graphical pointing device. When the keyboard controller is instructed to do so, keystroke and graphical pointing information are conveyed exclusively to the secondary processor, thereby enabling the portable computing device to perform some functions without requiring the main central processing unit to be operational and thus operate in a low power mode.
