  • Patent number: 9820226
    Abstract: In an example embodiment, there is disclosed herein an apparatus comprising a wireless transceiver and a controller coupled to the wireless transceiver and configured to receive data via the wireless transceiver. The controller operates the wireless transceiver at a first power save state where the wireless transceiver can receive a frame but other circuits are de-energized. The controller is responsive to the wireless transceiver receiving a frame while the wireless transceiver is in a first power state to determine whether the frame is a predefined wakeup frame. The controller provides additional power to the wireless transceiver responsive to determining the frame is a predefined wakeup frame.

  • Patent number: 9767798
    Abstract: Methods of low power detection of an activation phrase are described. A microphone system comprises dedicated hardware logic for detecting a pre-defined activation phrase in an audio stream received via a microphone. If the pre-defined activation phrase is detected, the hardware logic sends a trigger signal to activate a module, such as a main speech detection module, which is external to the microphone system and which may be in a low power standby state.

  • Patent number: 9001723
    Abstract: A method and system for managing broadcast of notifications indicating whether system information has changed, so as to enable served devices to determine when to read and store updated system information. A radio access network tracks changes in system information on a per wakeup cycle basis, so as to determine whether system information has changed since a last instance of broadcasting such a notification in a particular wakeup cycle. If system information has changed, the network responsively broadcasts an indication that system information has changed, so as to cause devices operating on that wakeup cycle to read and store the updated system information. Whereas, if system information has not changed, the network responsively broadcasts an indication that system information has not changed (or forgoes broadcasting an indication that system information has changed), so that devices operating on that wakeup cycle can avoid reading and storing the system information.

  • Patent number: 8847764
    Abstract: A radio frequency identification (RFID) system includes a portable RFID reader, and a read infrastructure that includes a distributed read structure, which may be part of a display (such as a shelf) for holding objects. The read structure is used to couple the RFID reader to RFID devices (tabs and/or labels) on or near the structure. The RFID reader and the read structure communicate in a near field or proximity region communication, without any use of a direct ohmic electrical connection. The RFID reader may have an antenna that is configured for near field or proximity communication with a coupler of the read infrastructure. The RFID reader may also have a separate antenna for use in far field communication. The RFID reader may be able to obtain information more efficiently in the near field or proximity mode, allowing information to be received faster and with greater reliability.

  • Patent number: 7680572
    Abstract: An onboard-equipment control apparatus controls activation of an onboard apparatus such as an air conditioner and termination of the operation of the onboard apparatus in order to prevent an onboard battery from running out of residual electric charge in advance. Upon detection of a state in which an onboard radio apparatus is not capable of receiving a termination command from a cellular phone or the cellular phone is not capable of transmitting a termination command to the onboard radio apparatus while the air conditioner is in operation, the onboard-equipment control apparatus forcibly terminates the operation of the air conditioner even before a termination condition is satisfied. Thus, the onboard battery can be prevented in advance from running out of accumulated electric charge required for operating the activated air conditioner thereafter.

  • Patent number: 7668127
    Abstract: The present invention relates to power management within the context of wireless ad-hoc networks. More specifically to the effects of using different transmit powers on the average power consumption and end-to-end network throughput in a wireless ad-hoc environment. This power management approach reduces the system power consumption and thereby prolongs the battery life of mobile nodes. Furthermore, the invention improves the end-to-end network throughput as compared to other ad-hoc networks in which all mobile nodes use the same transmit power. The improvement is due to the achievement of a tradeoff between minimizing interference ranges, reduction in the average number of hops to reach a destination, reducing the probability of having isolated clusters, and reducing the average number of transmissions including retransmissions due to collisions. The present invention provides a network with enhanced end-to-end throughput performance, and lower transmit power.

    Abstract: An electronic device (103, 200) employs a method and apparatus for selectively audibly alerting a user as to the status of the device's DC power source (119). The device receives input from the user indicating a time period during which the audible low power alert is not to be emanated from the device. After receiving such input, the device determines whether a low power condition exists during the time period and deactivates the audible low power alert if such a condition is met. Alternatively or additionally, after receiving the time period input from the user, the device may determine the likelihood of a low power condition occurring during the time period and activate the audible alert prior to commencement of the time period if such a condition is likely to occur, thereby providing the user advance notice of the potential for such a condition.
