  • Patent number: 12093473
    Abstract: An information handling system stylus transmits a wireless signal at a writing tip to enhance touch detection of the writing tip by a touchscreen display and receives wireless signals from the touchscreen display at a receiving antenna. To enhance control of wireless energy distributed at the writing tip, the receiving antenna is selectively coupled to the writing tip, such as by transitioning from a float of the receiving antenna to an interface with the stylus power source at transmit by the writing tip. Charge at the receiving antenna helps to shape the energy distribution from the writing tip, such as to match the energy distribution of other styluses in use at the touchscreen display.

  • Patent number: 11599988
    Abstract: A target image of a target circuit board and a gold image of a gold circuit board are taken by an image acquisition system. Fiducial points are located on the target image and on the gold image. Perspective transformation is performed on the target image using the fiducial points on the target image for reference and on the gold image using the fiducial points on the gold image for reference. After perspective transformation, an anomalous section of the target image is identified by identifying pixels that have different intensities between the target image and the gold image, the anomalous section being indicative of an unauthorized modification to the target circuit board.
