Optical data link system, and methods of constructing and utilizing same

Claim 1

Apparatus for high speed communication of data, comprising, in combination: (a) oscillator means for producing a synchronization clock signal; (b) timing and control means connected to and receiving clock signals from the oscillator means for producing timing and control signals, and including divider circuit first means for producing simultaneous transmitting and receiving timing and control signals; (c) synchronization means connected to the timing and control means for synchronizing the same to the clock signal of the oscillator means; said divider change circuit means includes a second transmitter circuit means for producing two frequency shift key time base carrier frequency representing respectively a high and low input data signal; said timing and control means further includes a second receiver circuit means, with each first and second transmitter circuit means and said first and second receiver circuit means including at least one counter; wherein said synchronization means includes edge detector means connected to said at least one counter of the timing and control means for receiving data signal and clearing said at least one counter on detection of transitions of the data received between high and low states; wherein said oscillator means includes a 24 Megahertz front-end oscillator; at least one light-emitting diode means connected to the transmitter circuit for transmitting light; at least one photosensor means connected to the receiver circuit for receiver circuit for receiving light; said diode means and photosensor means being arranged adjacent one another and directed substantially in a common direction.
