Claim 1
Independent Claim
235 words
In a sonar transmitting and reflection-receiving system having a first source of first time pulses having a first repetition rate of period T, means responsive to the pulses of said first source for generating ultrasonic pulses in a water medium, means for receiving reflections of said ultrasonic pulses and responsive thereto, for generating second timed pulses corresponding to the times of reception of said ultrasonic reflection pulses, the improvement in display means, comprising: a. a third source of third timed pulses of period t, where t is small compared to T; b. counter means comprising units and tens counters, each having 10 terminals, said tens counter responsive to said units counter, said units counter responsive to said first and third pulses for presenting electrical pulses sequentially on a plurality of N gate means in synchronism with said third pulses; c. means for starting said counter means in synchronism with said first pulses and for stopping said counter means on the count of N; d. said plurality of gate means having one input of each gate connected to one of said terminals in said units counter, a second input of each gate connected to one of said terminals in said tens counter, and a third input of each gate connected to said source of said second pulses; and e. the output of each gate means connected to one of a plurality of voltage sensitive light source.
