  • Publication number: 20250085811
    Abstract: Systems, methods, and devices are described that may mitigate display pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

  • Patent number: 8724336
    Abstract: A cardguide to be disposed in a computer chassis during use. The cardguide includes a track to accept an edge of a printed circuit board of a modular computer device to be disposed in the computer chassis during use. The cardguide further comprises an integral clip configured to retain at least a portion of a temperature sensing device during use. The clip provides for positioning the temperature sensing device within the computer chassis during use.

  • Patent number: 8503184
    Abstract: Provided in some embodiment is a module locking device including a first member coupled to a computer chassis during use, a second member coupled to the first member via a hinge. The hinge enables the second member to move between a first position that inhibits removal of one or more modules from the computer chassis during use and a second position that facilitates removal of one or more modules from the computer chassis during use. The module locking device also includes a locking mechanism that selectively locks the second member in the first position to inhibit removal of one or more modules from the computer chassis during use.
