  • Patent number: 11642747
    Abstract: Provided are methods and systems for aligning multiple parts using simultaneous scanning of features of different parts and using feature-based coordinate systems for determining relative positions of these. Specifically, a feature-based coordinate system may be constructed using one or more critical dimensions between features of different parts. The scanner may be specifically positioned to capture each of these critical dimensions precisely. The feature-based coordinate system is used to compare the critical dimensions to specified ranges. The position of at least one part may be adjusted based on results of this comparison using, for example, a robotic manipulator. The process may be repeated until all critical dimensions are within their specified ranges. In some embodiments, multiple sets of features from different parts are used such that each set uses its own feature-based coordinate system. The part adjustment may be performed based on the collective output from these multiple sets.

  • Publication number: 20230140652
    Abstract: This document describes methods and systems for an antenna system integrated with side-keys of an electronic device. The antenna system enables antenna integration in a metal frame using a metal support structure and fastener(s) to route antenna signals around side-key modules embedded in the frame without encountering or causing interference with the side-key modules. By using these techniques to integrate antennas on areas around the side-key modules, more antennas can be implemented on the electronic device, leading to improved capabilities supporting additional wireless standards and a better user experience in terms of improved communication quality.

  • Publication number: 20230107070
    Abstract: A detection circuit for detecting a clock signal includes a multiplexer, a digital-to-analog converter, a comparator, and a counter. The multiplexer outputs either a first signal or a second signal as a selection signal. The digital-to-analog converter outputs a reference voltage according to the selection signal. The comparator compares the clock signal to the reference voltage to generate a comparison signal. The counter counts a reference clock signal to generate an overflow signal, and resets the overflow signal according to the comparison signal. The overflow signal indicates the amplitude of the clock signal.

  • Patent number: 11615049
    Abstract: A programmable serial input-output controller is provided. A timer circuit performs a timing operation. An input pin is configured to receive an input signal from an external circuit. An output pin is configured to provide an output signal to the external circuit. In an output mode, the sequence controller provides an initial level to the output pin and controls the timer circuit to perform the timing operation. In response to a duration of the timer circuit performing the timing operation reaching first transmission time, the sequence controller inverts the level of the output pin and controls the timer circuit to re-perform the timing operation. In response to the duration of the timer circuit re-performing the timing operation reaching second transmission time, the sequence controller inverts the level of the output pin.
