Abstract
Improved Driver circuitry for multiple combination LED/silicon detector sensors arranged in an array or scattered in a machine, wherein the LEDs and detectors are connected in a matrix arrangement to common busses to reduce the number of connections and minimize interference. Grounding gates are toggled "ON" and "OFF" prior to actuating the driver circuitry to reduce the presence of live voice.
