  • Paralleled output self-encoding keyboard
    Patent number: 4088994
    Abstract: A standard format keyboard provides a paralleled, binary-coded output corresponding to an alphanumeric character or a function when the appropriate key head is depressed. A signal is coupled through the key mechanism to a set of parallel conductors which are positioned to be approached by a portion of the key mechanism. The conductors have minimum or maximum areas corresponding to binary zeros and ones, whereby the level of signal coupled also corresponds to a binary code (such as ASCII) for the character or function key depressed.
