  • Wireless camera system
    Patent number: 11245831
    Abstract: A system for providing controls signals to a wireless remote camera comprises a signal generating device that presents forward and inverse polarity pulse trains. A transmitter data converter circuit has a forward polarity input point for receiving the inverse polarity pulse trains and an inverse polarity input point for receiving the forward polarity pulse trains, and converts the forward and inverse polarity pulse trains to a conditioned unitary pulse train. A modulator circuit modulates the conditioned unitary pulse train onto an RF carrier. A demodulator circuit demodulates the modulated output wave to produce a reproduction of the conditioned unitary pulse train. A receiver data converter circuit converts the conditioned unitary pulse train to conditioned forward polarity pulse trains and conditioned inverse polarity pulse trains. A camera control circuit produces control signals based on the conditioned forward and inverse polarity pulse trains. A wireless remote camera receives the control signals.
