  • System and method for registering and identifying an input knob of a touch screen device
    Patent number: 10838523
    Abstract: A touch screen device includes a display screen having a touch surface, an input knob, and a microcontroller programmed to execute a method. The knob has a stationary member with conductive base pads facing the surface and a moveable member. The knob lacks a direct electrical connection to the surface. The microcontroller receives encoder signals as the moveable member moves with respect to the stationary member, with the signals being indicative of discrete touch events between the moveable member and the screen, e.g., via an intervening switch. The microcontroller processes the encoder signals to determine a direction of movement of the knob, and derives a true position of a center point of the knob using a position of each of the base pads. The microcontroller then controls an operation of the touch screen device.
