  • Patent number: 11023707
    Abstract: A cropped bounding box selection operation is performed on a video captured by a video capture and playback system, to select one or more cropped bounding boxes from the video for processing by a face detection operation. The cropped bounding box selection operation identifies objects from the video images and assigns a ranking to each identified object based on certain priority criteria; one or more cropped bounding boxes corresponding to the objects with the highest ranking(s) are then processed by the face detection operation to detect a face in each object.

  • Patent number: 11018752
    Abstract: An active repeater device includes a primary sector and one or more secondary sectors, receives a first beam of input RF signals. A first set of analog baseband signals, are generated based on received first beam of input RF signals. The first set of analog baseband signals are converted to a first set of coded data signals and control information is extracted from the first set of coded data signals by decoding only a header portion of the first set of coded data signals without demodulation of data portion of the first set of coded data signals. Based on the extracted control information, the first set of coded data signals are transmitted as beams of output RF signals to remote user equipment. The transmission is independent of demodulation of the data portion within the active repeater device to reduce latency for transmission of the first set of coded data signals.

  • Patent number: 10992270
    Abstract: A power amplifier apparatus supporting reverse intermodulation product (rIMD) cancellation is provided. The power amplifier apparatus includes an amplifier circuit configured to amplify and output a radio frequency (RF) signal for transmission via an antenna port. The antenna port may receive a reverse interference signal, which may interfere with the RF signal to create a rIMD(s) that can fall within an RF receive band(s). A reverse coupling circuit is provided in the power amplifier apparatus to generate an interference cancellation signal based on the reverse interference signal. The amplifier circuit is configured to amplify the interference cancellation signal and the RF signal to create an intermodulation product(s) to suppress the rIMD(s) to a determined threshold. By suppressing the rIMD(s) in the power amplifier apparatus, it is possible to support concurrent transmissions and receptions in a number of RF spectrums while in compliance with stringent regulatory spurious emissions (SEM) requirements.
