1. Apparatus for electronically timing and recording a moving object as it travels over a measured course, said apparatus comprising:

  • a plurality of ultrasonic detector means positioned in predetermined spaced relationship along said course for producing a sequence of RF detection signals upon ultrasonic detection of an object travelling over said course;

    timing circuit means for receiving said RF detection signals and for computing the elapsed times of travel of said object over said course as a function of said sequence of detection signals;

    video recording means of capturing and recording a sequence of video frames depicting the travel of said object over said course; and

    means for recording the elapsed times computed by said timing circuit means along with said sequence of video frames capturing the travel of said object such that when said recorded timing information and said sequence of video frames are played back on a video monitor, the timing information is displayed along with said video frames of said travelling object.
