  • Publication number: 20160118805
    Abstract: A wireless power transfer system and method is provided. The system includes a source coil that is coupled to a power supplying device and a receiver coil that is coupled to a power receiving device. In operation, when the source coil is energized by the power supplying device and the receiver coil is positioned within a predetermined range of distances from the source coil, the receiver coil is inductively coupled to the source coil at a predefined magnetic resonance frequency to wirelessly transfer power from the power supplying device to the power receiving device. The power receiving device measures a voltage level at the receiver coil and sends information pertaining to the voltage level to the power supplying device. The power supplying device adjusts voltage at the source coil based on comparing the voltage level with a predetermined threshold determined for the power receiving device.

  • Publication number: 20160118834
    Abstract: A portable radio device is adapted to function as a wireless charger. The device includes a power supply source, a power control circuit, a controller, a power amplifier connected to the power control circuit to draw a first supply voltage from the power control circuit, and a source coil. In operation, the controller receives a request for charging at least one other device coupled to a receiver coil. When the receiver coil is positioned within a predetermined range of distances from the source coil, the controller switches a connection of the power control circuit to the source coil and controls the power control circuit to increase the voltage to a second supply voltage provided to energize the source coil and to inductively couple the source coil to the receiver coil at a predetermined magnetic resonance frequency for wirelessly charging the at least one other device.

  • Publication number: 20160103198
    Abstract: An RFID tag reading system and method estimate bearings of RFID tags. When the RSSI of a primary and/or secondary RFID receive signal is below a threshold, a primary receive beam is steered in a limited scan to an array of locations distributed around the location at which the RSSI of the primary receive signal is a maximum, and the RSSI of the primary receive signal is recorded at each location. The recorded RSSIs are processed to determine an effective weighted center of distribution of the recorded RSSIs, and the bearing for the tag based on the weighted center of distribution is thus estimated.

  • Patent number: 9252850
    Abstract: A method, a system, and a server provide context aware multiple-input-multiple-output MIMO antenna systems and methods. Specifically, the systems and methods provide, in a multiple MIMO antenna or node system, techniques of antenna/beam selection, calibration, and periodic refresh, based on environmental and mission context. The systems and methods can define a context vector as built by cooperative use of the nodes on the backhaul to direct antennas for the best user experience as well as mechanisms using the context vector in a 3D employment to point the antennas in a cooperative basis therebetween. The systems and methods utilize sensors in the nodes to provide tailored context sensing versus motion sensing, in conjunction with BER (Bit Error Rate) measurements on test signals to position an antenna beam from a selection of several “independent” antenna subsystems operating within a single node, as well as, that of its optically connected neighbor.

  • Patent number: 8823518
    Abstract: A sensor enhanced communication device (200) is provided with a wake mode, a standby mode and sleep mode. The sleep mode is a periodic occurrence within the standby mode which places a cluster of sensors and transducers (202) into a state of arousal in which the sensitivity of the transducers and sensors is increased while the sampling rate is decreased. Incremental learning can occur during the sleep mode as well as basic memory transfers. Since the cluster does not have to re-acquire information upon entering wake mode, the overall power efficiency is improved.

  • Patent number: 8611546
    Abstract: A radio configured to dynamically control cancellation of undesired signals in an audio stream. The radio includes a noise cancellation processor configured to receive an audio stream from a user and to alter information in the audio stream by filtering out undesired signals in the audio stream. The radio also includes a receiving component configured to receive a data packet from a remote device, to retrieve configuration information from the data packet, and to dynamically apply the configuration information, while the radio is being used by a user, to settings associated with the noise cancellation processor. A dynamically enabled noise cancellation processor suppresses undesired signals associated with a subsequent incoming audio stream provided by the user and transmits at least one of an altered audio stream or an unaltered audio stream to the remote device.

  • Patent number: 8509923
    Abstract: Methods for reducing sensor support power in a sensor network include a primary node locating a secondary node. The primary node has a primary node sensor profile, and the secondary node has a secondary node sensor profile. The secondary node sensor profile is compared to the primary node sensor profile. A virtual sensor profile is constructed based on the comparison between the primary and secondary sensor profiles. The virtual sensor profile reduces redundant sensor data gathering between the primary and secondary sensor nodes. A power consumption optimization hardware configuration for the secondary node is determined to provide sensor data for the virtual sensor profile, and the determined hardware configuration is assigned to the secondary node.
