  • IR receiver using IR transmitting diode
    Patent number: 6826370
    Abstract: Circuitry using infra-red (IR) diodes in remote control units. In one embodiment an IR LED is used both as a transmitter diode and also as a receiver diode responsive to light to thereby develop photocurrents and/or voltages for use by external circuitry. In a second embodiment an improved amplifier circuit is provided for an IR LED and IR photo detector diode which is mounted behind, and receives light through, the transmitter IR LED.
    Type: Grant
    Filed: December 23, 2003
    Date of Patent: November 30, 2004
    Assignee: Universal Electronics Inc.
    Inventors: Marcus Escobosa, Thomas M. Salsman, William L. Brown
