  • Patent number: 10848256
    Abstract: Disclosed are techniques for handling of radio frequency (RF) front-end group delays for roundtrip time (RTT) estimation. In an aspect, a network node transmits first and second RTT measurement (RTTM) signals to a user equipment (UE) and receives first and second RTT response (RTTR) signals from the UE. The network node measures the transmission times of the RTTM signals and the reception times of the RTTR signals, and the UE measures the transmission times the RTTM signals and the transmission times of the RTTR signals. The group delays of the transmit/receive chains of the network node and the UE are determined for one set of transmit/receive chains based on the first RTTM signal and first RTTR signal. The group delays of the transmit/receive chain used for the second RTTM signal and the second RTTR signal are determined relative to the group delay of the one set of transmit/receive chains.

    Abstract: Methods, systems, and computer programs are presented for a self-encrypting device (SED) incorporated into a host system. In one example, the host system includes a memory, a processor, a data channel in communication with the memory and the processor, and the SED. The SED comprises an authentication subsystem, a storage subsystem that stores encrypted data that is encrypted with an encryption key provided by the authentication subsystem, a radio frequency (RF) transceiver, and a data interface in electrical contact with the data channel. The data interface is locked from sending and receiving data until the SED is unlocked by the authentication subsystem with user-authentication information received via the RF transceiver.

  • Patent number: 10693511
    Abstract: Radio circuitry wirelessly serves User Equipment (UE) with dynamic direction-of-arrival reception. Control circuitry determines a primary direction-of-arrival for a user signal and configures a digital filter for the primary direction-of-arrival. Detection circuitry filters the user signal with the digital filter configured for the primary direction-of-arrival and recovers user data from the user signal. The control circuitry determines increased radio noise and/or uplink utilization reconfigures the digital filter for multiple directions-of-arrival. The detection circuitry filters a subsequent user signal with the digital filter configured for the multiple directions-of-arrival and recovers additional user data from the subsequent user signal.

  • Patent number: 10685415
    Abstract: A system and method for tracking a milk crate, a bread tray, or other instrument for transporting goods of a business makes use of an electronic tracking tag attached to the milk crate, the bread tray, or other transport instrument. The electronic tracking tag includes a microprocessor and a transceiver, and wirelessly transmits an identifying electronic transmission at predetermined time intervals. The systems and methods further make use of a wireless network including a plurality of nodes, where each of the nodes is positioned at a predetermined location and receives the identifying electronic transmission from the electronic tracking tag upon movement of the electronic tracking tag into proximity with a node. Each of the nodes are then connected to a central computer server that identifies a location of the electronic tracking tag based on the predetermined location of the node.

  • Patent number: 10622845
    Abstract: System and methods are described herein for providing wireless power to a target device, such as a laptop computer, a mobile phone, a vehicle, robot, or an unmanned aerial vehicle or system (UAV) or (UAS). A tunable multi-element transmitter may transmit electromagnetic radiation (EMR) to the target device using any of a wide variety of frequency bands. A location determination subsystem and/or range determination subsystem may determine a relative location, orientation, and/or rotation of the target device. For a target device within a distance range for which a smallest achievable waist of the Gaussian beam of the EMR at an operational frequency is smaller than the multi-element EMR receiver of the target device, a non-Gaussian beamform may be determined to increase efficiency, decrease overheating, reduce spillover, increase total power output of rectenna receivers on the target device, or achieve another target power delivery goal.

    Abstract: In some aspects, the disclosure is directed to methods and systems for virtual angle-of-arrival (AoA) or angle-of-departure (AoD) tracking for virtually tracking multiple Targets. The wireless devices (e.g. Tracker and Targets) may participate in a mesh configuration and share data within the mesh. A first device may purport to be a virtual tracker, while acting as an AoA or Angle of Departure (AoD) Target. The devices being tracked (e.g. virtual targets), may instead operate as Trackers. Processor- and energy-intensive calculations may be distributed to the virtual targets and transmitted via the mesh for aggregation at the virtual tracker.
