  • Patent number: 8346234
    Abstract: An electronic device, for example, a laptop computer includes a processor, a transceiver module, for example, a Bluetooth module and a memory. The memory includes a platform proximity agent, which may be implemented as a series of instructions, which when executed by the processor, causes the processor to receive a Bluetooth signal from a corresponding provisioned Bluetooth device, for example, a cellular telephone. Next, determine whether the received signal exceeds both a strength threshold level and a predetermined time threshold level, where the signal strength and time threshold levels are established when the laptop and a corresponding cell phone are paired during a provisioning process. When the received signal strength and duration both exceed the corresponding policy based thresholds, the laptop enters (or remains in) a full power state with full access to the monitor and the platform.

  • Patent number: 8295762
    Abstract: Systems and methods for using distributed processing in conjunction with blind source separation techniques for signal processing and acquisition in sensor network environments are provided. In the distributed blind source separation framework, sensors each perform some processing of sensor signals rather than transmitting such signals over long distances, and/or outside of the sensor network, to be processed at a central location. Sensors attempt to own a source signal, which can only be owned by one active sensor. Sensors owning a source signal broadcast the signal directly or indirectly so it is perceived by users. Sensors receive information from other sensors in their sensor neighborhood, including observed signals of the other sensors and the estimated source signals of sources owned by the other sensors. This allows owning sensors to extract the respective source signals of the sources they own and all redundant sensors to check for any non-owned source signals present.

In one embodiment, the method includes the steps of: (a) modifying a beam by introducing a beam-jitter in a beam-forming pattern; (b) receiving an estimated channel quality information, CQI, from a user terminal; (c) accounting for effects of the beam jitter on the estimated CQI to obtain a jitter-adjusted CQI estimate; (d) and using the jitter-adjusted CQI estimate during user scheduling for a future transmission to the user terminal.

  • Patent number: 8249637
    Abstract: An object of the present invention is to provide means for eliminating a transmission delay when transmitting emergency information for the sake of relief, security, or the like in a wireless device in conformity with the wireless LAN standard in which if radio waves transmitted from peripheral devices are detected, transmission has to be stopped. In a multimode wireless communication scheme having two or more communication schemes, priorities of the communication schemes are set. A high priority or low priority regarding to a message is described in a “message type” data field of a frame of a controlling channel output from the access point side to the terminal side. When the frame of the controlling channel is decrypted on the terminal side, the message type is confirmed, so that the type of a service channel used thereafter is confirmed and the channel is coupled.

  • Publication number: 20120202547
    Abstract: The number of communication channels necessary for communication with a terminal is calculated by using type and volume of data to be transmitted. When calculated number of communication channels is one, a single communication channel is allocated based on quality information of a communication line to the terminal and, when calculated number of communication channels is more than one, then more than one communication channels are allocated based on the quality information. Allocation information used for notifying of allocated communication channels is generated based on virtual channels, which are defined in advance as channel units having a combination of a plurality of consecutive communication channels, and the allocation information is transmitted to the terminal.

  • Publication number: 20120202548
    Abstract: In a technique for communication with a station on a wireless network, the technique includes forming a plurality of narrow-band beams, each having a different angular direction from an antenna of a base station and collectively distributed over a beamspace to form a pseudo-omni-directional beam pattern. That beamspace may span an entire spherical region or a portion thereof, for example, when the narrow-band beams are broadcast over a sector of an entire spherical region. The technique may assign each of the plurality of narrow-band beams to a different frequency band (such as a different channel band or sub-channel) on the wireless network. The technique may simultaneously broadcast the plurality of narrow-band beams in a time-varying manner such that the angular direction of each of the plurality of narrow-band beams varies with time, where that variation may be random or ordered.
