Patent ID: 8098753

Claim:
A communication and position finder system comprising: a demodulator and a first processor for demodulating and processing a modulated signal for generating from said modulated signal a demodulated processed position finder signal; a second processor for receiving and processing an input signal, said input signal received from an infrared (IR) signal transmitter, for generating from said input signal a processed IR input signal for providing said processed IR signal to an interface unit; a third processor for receiving and processing said processed IR signal for generating from said processed IR signal a cross-correlated in-phase and quadrature-phase processed signal; a fourth processor comprising an orthogonal frequency division processor for generating a orthogonal frequency division processed signal from a camera generated signal; a fifth processor for generating a signal from processing said processed position finder signal generated by the first processor, with one or more of the signals generated by the second, third or fourth processor; a modulator for modulation of said signal generated by the fifth processor; and a transmitter for transmission of said modulated signal.
