  • Publication number: 20240121729
    Abstract: Examples of transmit power controls are described herein. In some examples, an electronic device includes an imaging capturing device to capture a video stream. In some examples, the electronic device includes video processing circuitry. In some examples, the video processing circuitry may measure background motion in the video stream. In some examples, the video processing circuitry may detect human proximity based on the measured background motion. In some examples, the video processing circuitry may control transmit power in response to the human proximity detection.

  • Patent number: 9008251
    Abstract: The present invention discloses an adaptive phase-shifted synchronization clock generation circuit and a method for generating phase-shifted synchronization clock. The adaptive phase-shifted synchronization clock generation circuit includes: a current source generating a current which flows through a node to generate a node voltage on the node; a reverse-proportional voltage generator coupled to the node for generating a voltage which is reverse-proportional to the node voltage; a ramp generator receiving a synchronization input signal and generating a ramp signal; a comparator comparing the reverse-proportional voltage to the ramp signal; and a pulse generator for generating a clock signal according to an output from the comparator.
