Abstract:
A system for finding objects (9, 10a, 10b) to which with a tracking device (11a, 11b) is attached, as well as a tracking device (11a, 11b). The tracking decices comprise an electrical power source (15), a processor (14), a memory and a wireless communication module (12). The wireless communication module is capable of sending tracking messages (17) and of receiving messages. The system comprises a system computer (30) that is capable of communicating by way of a communication network with wireless communication modules thereof that are capable of receiving tracking messages (17) or capable of sending messages for the wireless communication module (12) of a tracking device (11a, 11b). The system computer (30) is capable of dispatching a system message with a loss enquiry (310) or with an at-rest enquiry (309) to a data processing device of the applicant. It is also capable of dispatching a system message (18, 19) with a no-loss notice (305) or with a loss notice (311, 319) or with an at-rest notice (307) to the tracking device (11a, 11b). The tracking device (11a, 11b) comprises and a motion detector (16) and is capable of at least temporarily increasing or decreasing the mean power over time of the wireless communication module (12) in consequence of a transport supposition (205) on the basis of an assessment of at least the motion signal.
Abstract:
A sensor module that transmits at a predetermined transmission interval, via a network, data obtained by measurement to an externally installed information processing device sets, together with a nearby sensor module, a predetermined module group in which a plurality of sensor modules for transmitting measurement data according to data processing in the information processing device are put together. Then, together with the nearby sensor modules, one sensor module among the predetermined module group is set as a reference sensor module for which a transmission interval is maintained at a predetermined transmission interval, and transmission intervals of measurement data of sensor modules other than the reference sensor module are changed to a prolonged transmission interval that is longer than the predetermined transmission interval. With this, a reduction in power consumption is realized as much as possible in the sensor module that measures environmental parameters such as temperature and humidity and transmits the measured data to the information processing device.
Abstract:
Operations for a WLAN-capable remote control device and a controlled device are disclosed. A first network device (e.g., remote control) may receive a user input for controlling operation of a second network device (e.g., controlled device) of a communication network. The first network device may transition to an active operating state in response to receiving the user input. The first network device may transmit the first user input to the second network device. The first network device may exit the active operating state in response to successfully transmitting the first user input to the second network device.
Abstract:
To conserve power in a controlling device having a processing device in communication with an input element and a transmitting device the processing device is caused to be placed into a low-power state for at least a portion of a transmission inactive interval intermediate the transmission of at least a pair of command frames. The command frames are caused to be transmitted by the transmitting device in response to an activation of the input element sensed via the processing device to thereby command a functional operation of an intended target device.
Abstract:
A low-power wireless network involves a plurality of RF-enabled fluorescent lamp starter units. In each of a plurality of intervals, a receiver of a starter unit operates in a receive mode during a beacon slot time, and for the majority of the rest of the interval operates in a low-power sleep mode. The starter unit wakes up and listens for a beacon each beacon slot time, regardless of whether a beacon is transmitted during that interval or not. A starter unit can be commanded to schedule a future action (for example, for a time between widely spaced synchronizing beacons) by making one of the beacons a scheduling beacon. The scheduling beacon includes a field that the starter unit uses to schedule the future action. If the scheduled action is to be canceled before the next widely spaced synchronizing beacon, then an action-canceling beacon is communicated in the next interval.
Abstract:
Aspects of the present invention include a device comprising a memory storing instructions and a processing circuit executing the instructions to detect a first user action. The instructions may further include instructions to establish a first user action state based on the detected first user action, designate a first mode based on the first user action state, determine if a second user action, consistent with a first detection condition associated with the first mode, has taken place, when the second user action has taken place, establish a second user action state based on the second user action, and designate a second mode based on the second user action state, the second mode consuming more power than the first mode.
Abstract:
An acceleration sensor (3) detects an acceleration. A timer (6) measures elapsed time. A calculation means (12) calculates jerk J of a remote controller (1) on the basis of an acceleration detected by the acceleration sensor (3). A factor determination means (13) determines whether a user is holding the remote controller (1) in his/her hand on the basis of the change of the jerk J that is obtained from an index value calculated by the calculation means (12) and an amount of time measured by the timer (6). A sleep control means (14) turns on display of a display (5) if the factor determination means (13) determines that the user is holding the remote controller (1) in his/her hand.

Abstract:
A device for eliminating standby power consumption of an electronic appliance having infrared remote control switch capability is provided, which includes: a control unit; an infrared remote control signal receiving unit connected thereto; an infrared remote control signal transmitting unit, connected to the control unit; a controlled electronic appliance power supply switch unit, connected to the control unit, a power supply unit, an external power source and a power input end of a controlled electronic appliance; and the power supply unit of the device, connected to the control unit, the controlled electronic appliance power supply switch unit, and the external power source. For the device for eliminating standby power consumption of an electronic appliance having infrared remote control switch capability, during initial installation and setting, an infrared remote power-on/off signal of the controlled electronic appliance and a preheating time after the power source of the controlled electronic appliance is turned on are received, detected and stored. In subsequent use, the power supply of the controlled electronic appliance is turned off upon receiving the infrared remote control power-off signal, the power supply of the controlled electronic appliance is turned on upon receiving the infrared remote control power-on signal, and after the controlled electronic appliance finishes preheating, an infrared remote control power-on signal is transmitted to the controlled electronic appliance to turn on the controlled electronic appliance. Therefore, without changing normal remote power-on/off operations of the user, standby power consumption of the electronic appliance having infrared remote control switch capability is eliminated.
