  • Patent number: 11160020
    Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may identify a sequence of on symbols and off symbols for transmission to a wake-up radio (WUR) of a wireless device. The AP may assign a modulation symbol from a set of possible modulation symbol waveforms to at least each on symbol in the sequence. The modulation symbol waveforms may be assigned to sequential on symbols in a random or pseudorandom order, e.g., by applying a random phase rotation to a stored modulation symbol waveform, by applying a random cyclic shift to a stored modulation symbol waveform, or by applying a random or pseudorandom phase-shift keying value to each subcarrier in a multicarrier system to generate a modulation symbol waveform. The AP may transmit the sequence to the WUR based at least in part on the assigned modulation symbol waveforms.

  • Patent number: 11124154
    Abstract: Techniques and methods for security vehicle systems. For instance, a control system may receive a reported location of a vehicle. The control system may then receive sensor data generated by the vehicle. After receiving the sensor data, the control system may analyze the sensor data with respect to additional data associated with the reported location. The additional data may include map data representing the reported location and/or additional sensor data received from another vehicle or user device. The control system may determine whether the vehicle is at the reported location. If the control system determines that the vehicle is at the reported location, the control system may determine that the vehicle is not compromised. However, if the control system determines that the vehicle is not at the reported location, the control system may determine that the vehicle is compromised and may then perform one or more remedial actions.

  • Patent number: 11095337
    Abstract: A communication system includes a passive wireless sensor and a sensor computing device. The passive wireless sensor is operable to receive a radio frequency (RF) signal including a carrier frequency signal and a modulated sense request signal, generate a power supply voltage, determine received signal strength (RSSI) of the RF signal, and determine whether the RSSI is at a desired level. When the RSSI is at a desired level, the passive wireless sensor generates a response RF signal including the carrier frequency and a coded sense response signal representative of a sensed environmental condition. The sensed environmental condition affects impedance of a front-end of the passive wireless sensor to produce an affected impedance. The passive wireless sensor generates the coded sense response signal based on tuning the affected impedance to resonate with the carrier frequency signal.

  • Patent number: 9959434
    Abstract: The present invention provides a method of operating a bi-directional communication system between a plurality of communication devices, which comprises at least one communication controller and a plurality of nodes including a first node. The method includes periodically broadcasting a beacon signal from said communication controller at a broadcast interval via a channel of a first host. The beacon signal contains a first address of the communication controller. The method further includes periodically scanning the beacon signal on the first host by the first node. Upon detecting of the beacon signal by the first node, the first node transmits an identification payload to the communication controller. Upon receipt of the identification payload by the communication controller, an acknowledgement signal is transmitted to the first node.

  • Patent number: 9928721
    Abstract: Passive wireless transponders can perform transponder-to-transponder communication when illuminated by an interrogation carrier wave. The transponder-to-transponder communication permits each transponder to determine the identity of “other” proximately transponders. The transponder-to-transponder communication optionally permits each transponder to identify a “nearest neighbor” using one or more backscatter signal properties such as received signal strength or time-of-flight. Using this information and one or more externally supplied or internally stored instruction sets transponders can provide neighboring transponder data to an interrogator. Using this “neighbor” data, the interrogator can provide a system user with data indicative of the relative locations of a plurality of tags arranged in a one or two dimensional matrix.

  • Patent number: 9773136
    Abstract: A radio frequency identification (RFID) tag reading system and method accurately and rapidly determine, in real-time, true bearings of RFID tags associated with items in a controlled area. Primary transmit and receive beams are steered over the area, and multiple secondary receive beams are substantially simultaneously steered to a plurality of bearings in the area. The highest signal strength of secondary receive signals from the secondary receive beams determines an approximate tag bearing of each tag. Two secondary receive beams at opposite sides of the approximate tag bearing in elevation are selected to obtain a pair of elevation offset signals, and two secondary receive beams at opposite sides of the approximate tag bearing in azimuth are selected to obtain a pair of azimuth offset signals. The elevation offset signals and the azimuth offset signals are processed to determine a true bearing for each tag in real-time.
