  • Patent number: 8786291
    Abstract: An in-situ unplug detector circuit detects when a cable is disconnected or unplugged. Detection does not have to wait for normal signaling to pause, such at the end of a frame or timeout. Instead, detection occurs during normal signaling. When the cable is disconnected, the transmitter no longer drives the load at the far end of the cable, and thus can drive the near end to a higher high voltage and to a lower low voltage. The increased voltage swing is detected by a detector at the near end that amplifies the transmitter output to the cable. A fast detector has a higher bandwidth and faster response time than a slow detector, and generates a fast detect signal that crosses over a slow detect signal. When the cable is disconnected, the fast detect signal again crosses over the slow detect signal, and decision logic activates an unplug signal.

  • Publication number: 20130321010
    Abstract: Defects in a touch sensor are detected by coupling the sensor lines to a common signal line. Each of the sensor lines is tested by disconnecting the sensor line from the common signal line, connecting it to a voltage (e.g., ground) and comparing the voltage on the common signal line to a reference voltage. Detected defects include a short circuit between any two transmit and/or receive lines and a short between any transmit or receive line to ground.
