Abstract
Abstract A circuit consisting of five cascaded binary coded decimal, UP-DOWN circuits with associated gates, a first input causes the counters to count up, at a 10 Mhz rate until any second input, which latches into memory the accumulated time in the counters, and causes the counters to count down at 5 Mhz rate, when the counters reach zero an output pulse, suitable for triggering photo flash strobes is generated.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
231 words
A system for sensing high velocity moving objects and providing an electrical output pulse as the object passes a point independent of variation in velocity of the object, comprising: first and second means for sensing a moving object and outputting signals in response thereto, a gate circuit connected to said sensors; an oscillator clock outputting a timing signal said oscillator clock being connected to the gate circuit; first and second counting means connected to the gate circuit said first and second counting means being driven by said oscillator clock and being activated by signals from said first and second means for sensing a moving object whereby a signal from the first sensing means will cause the gate circuit to switch the first counting means on, and a signal from the second sensing means will cause the gate circuit to switch the second counting means on and the first counting means off; pulse generating means connected to the second counting means, whereby an output pulse is generated when said second counting means reaches a preselected count; a time memory circuit connected to said first and second counting means for storing the output of said first and second counting means; means for displaying the count of said first and second counting means, and pulse receiving means adapted to be activated by the pulse generating means when said moving object passes a designated point.
