Electronic timing and recording apparatus
First Claim
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.

Abstract
The disclosed apparatus electronically times and records a moving object as it travels over a measured course. The apparatus is especially useful in recording and timing an athlete running over a measured course in order to determine the overall athletic prowess of the athlete. The apparatus provides more accurate and uniform testing of an athlete'"'"'s ability to run a predetermined distance as fast as possible. The apparatus includes a plurality of ultrasonic detectors positioned in predetermined spaced relationship along a course over which an athlete runs (object moves). A sequence of RF detection signals are sent to a timing circuit which computes the elapsed times of the athlete (object) over the course. The times are recorded along with video information produced by a video camera. When the timing information and recorded scene are played back on a video monitor, the timing information is displayed along with the video image to facilitate analysis of the recorded event.
