  • Patent number: 9691315
    Abstract: A touch-type input device includes a touch panel including drive electrodes and sensor electrodes. Capacitors are formed at intersections of the drive electrodes and sensor electrodes. A controller determines whether a conductive foreign matter exists on the touch panel from raw data values indicating changes in the capacitances of the capacitors from initial reference values. The controller determines touching of the touch panel from control data values indicating changes in the capacitances of the capacitors from control reference values changed when a conductive foreign matter exists. When the raw data values indicate existence of a conductive foreign matter, the controller sets the control reference value of each capacitor to a raw data reference value corresponding to the present raw data value. The controller updates the initial reference value when the touch-type input device is activated and updates the control reference value when the control reference value is erroneous.

  • Patent number: 9626741
    Abstract: Systems and methods dynamically configure a display (104) of an electronic device (102) to a desired display resolution and/or a magnification factor without noticeable impact on the user viewing experience. According to certain aspects, the distance between a user (100) and the display is measured (1002), and the desired display resolution is determined (1006) based on the distance. If a user is exhibiting (1008, 1010) symptoms of presbyopia, a magnification factor may be determined (1012). A request indicating the desired display resolution and/or magnification factor is transmitted (1016) to a server that supplies images, such as pictures or videos. The image is received (1018) from the server and displayed (1020) on the display. A focus area distance and/or a pupil orientation of the user may also influence the desired display resolution. Bandwidth, processing, and power savings may result through the use of these systems and methods.
