  • Publication number: 20240204399
    Abstract: Implementations described herein relate to a phased array antenna module with rotational control. In some implementations, a mobile device includes at least one processor, motion sensors configured to provide sensor data to the processor, and a phased array antenna module. The antenna module includes an antenna array that includes multiple antennas arranged linearly along a first axis. A rotary actuator is coupled to the antenna module and can rotate the phased array antenna module about a second axis that is parallel to the first axis. The processor performs operations including determining an orientation of the mobile device based at least on the sensor data from the motion sensors, and providing control signals based on the orientation of the mobile device to the rotary actuator to cause the rotary actuator to rotate the phased array antenna module about the second axis.

  • Patent number: 12001603
    Abstract: The present disclosure describes systems and techniques directed to detecting a user's gaze and using millimeter electromagnetic waves to actuate a focus system of a contact lens worn by the user. The described systems and techniques include a contact lens (108) having a focus system (222) and contact lens circuitry (226) that includes transceiver circuitry (228), logic circuitry (230), and memory circuitry (232). The memory circuitry (232) stores instructions of a focus manager application (234) that, when executed by the logic circuitry (230), directs the contact lens (108) to actuate the focus system (222) in response to receiving a signal (110) having a millimeter wave (114).

  • Patent number: 10778345
    Abstract: The representative embodiments discussed in the present disclosure relate to techniques in which the operating characteristics (e.g., gain and/or efficiency) of a power amplifier in a transmitter may be regulated according to an operation mode of the transmitter. More specifically, in some embodiments, different look-up tables (LUTs) may be employed for each mode of operation to suitably adjust the supply voltage to the power amplifier and modulate its operating characteristics based on power input to the power amplifier. Further, in some embodiments, a method to calibrate a LUT for uplink carrier aggregation (ULCA) operation mode of the transmitter may be employed to populate a LUT used to suitably adjust the supply voltage during ULCA.

  • Patent number: 10135476
    Abstract: An electronic device includes an antenna configured to receive a wireless transmission. The wireless transmission includes noise and data to be received. The electronic device includes a signal splitter that splits the wireless transmission into a first signal and a second signal. The electronic device includes a filter configured to filter the data to be received in the first signal. Furthermore, the electronic device includes merging circuitry configured to subtract the first signal from the second signal to reduce the noise in the second signal.
