Abstract:     An optoelectronic communications system in which the transmitter has controlled pulse train duration, pulse rate and pulse width, and a receiver which is sensitive to the pulse rate of the transmitter. The transmitter is incorporated into a firearm replica for a shooting gallery and the receiver is a target displaying a visible light source which is extinguished for a predetermined time period when energy from the transmitter strikes the target.

First Claim:
Show all 6 claims
I claim:     1. An optoelectronic communications system, comprising:
  • transmitter means for transmitting energy substantially in the optical spectrum range, said transmitting means including:
  • transducer means for converting electrical input energy to energy in said optical spectrum,
  • pulse generator means for generating electrical power pulses at a predetermined pulse rate and connected as input energy to said transducer means, said pulse generator means including a monostable multivibrator triggered by an oscillator;
  • pulse train duration control means connected to said pulse generator means for operating said pulse generator means only for a predetermined time duration, said pulse train duration control means including a resistor-capacitor timing circuit with its output connected to the inputs of a NOR gate, the output of the NOR gate being connected to said pulse generator means whereby the charging of said capacitor to a predetermined voltage causes said NOR gate to change state;
  • receiver means for receiving energy substantially in said optical spectrum range, said receiver means including,
  • detecting means for detecting energy in said spectrum and generating an electrical signal in response thereto,
  • pulse rate detection means responsive to said electrical signal occurring at a predetermined rate, said rate detection means generating a control signal in response thereto, said detecting means including a phase locked loop circuit driven by said electrical signal, and
  • display means for generating a visible display from said receiver means, said display means being responsive to said control signal to extinguish said visible display for a predetermined time period.
