  • Video signal termination detection circuit
    Patent number: 9473710
    Abstract: A video signal termination detection system includes an input configured to connect to a video driver that produces a video signal, an output configured to connect to a video receiver that operates with a signal type, a detection circuit connected between the input and the output and configured to detect the signal type of the video receiver and to output a detection signal, and a conversion circuit configured to receive the video signal from the video driver and to convert the video signal to the signal type if the video signal is different than the signal type.
    Type: Grant

  • Faraday cage for camera
    Patent number: 8077480
    Abstract: A camera includes an electrically conductive housing defined by exterior walls and an interior cavity. The exterior walls of the housing have a lens opening and a connector opening formed therein. An imaging device is disposed within the interior cavity of the housing and communicates with the lens opening. A printed wiring board (PWB) is disposed within the interior cavity of the housing separating the imaging device from the connector opening. The PWB has an electrically conductive chassis plane operatively connected to the exterior walls of the housing so that the chassis plane and the housing form at least a partial Faraday cage around the imaging device.
