  • Method and apparatus for checking the functions of a display system
    Patent number: 4541066
    Abstract: A method and apparatus for checking the functions of a display system display data which is received from a processing unit, store the displayed data, and check the stored data for identity with the data which is to be received and displayed. The check determines not only whether the display system has properly received the data, but also checks for malfunctions in the display system itself, such as a short circuit or an open circuit within the display unit, because the stored data can only correspond to the data intended for display when no malfunctions have occurred in either the display system or in the circuit for receiving the data.
