ABSTRACT:
A device for measuring the speed of a moving object has first and second impact detectors separated by a preselected known distance and disposed in the path of movement of the object. As the object strikes the first and second detectors, the detectors each produce a signal. The signals are separated by a time interval indicative of the distance between the detectors. The elapsed time between the signals is measured by a counter device, and the speed of the object is calculated by a programmable device.
