Abstract: A scorekeeper and distance indicator for use with a golf cart measures distance traversed by the golf cart and uses the measured distance in conjunction with stored information about a hole being played to determine the remaining distance to the pin. The apparatus displays the remaining distance, the number of the hole being played and a cumulative score. The apparatus is adaptable to store scores and other information for a plurality of players. A portion of the apparatus that includes a memory device can be removed from the golf cart and taken to a remote location to read or print scores. The increasing use of golf carts, and especially of powered golf carts, makes it feasible to use an odometer to measure the distance traversed by the golf cart. The availability of inexpensive microprocessor chips makes it feasible to combine information from an odometer or the like about measured distances with stored information about the characteristics of a golf course.

Abstract: Swim/sporting event timer/counter. A waterproof housing has upwardly projecting digital displays and two spaced ultrasonic receivers. A swimmer wears an ultrasonic transmitter tuned to ultrasonic receivers. by measuring the time differential for the ultrasonic signals from the transmitter to reach the receivers in the housing, the position of the swimmer (i.e., in front of, directly over, or behind the housing), is determined. Laps are identified by determining when the transmitted signal changes from being received by the two receivers by an increasing time differential to being received by a decreasing time differential. Each time the swimmer passes over the housing, the numbers on the display are inverted so that the swimmer may look down into the water and see the time regardless of which direction the swimmer is traveling in the lane or other predetermined course.

Abstract: A swim/sporting event timer/counter times a athlete moveing along a predetermined path based on signals received from the athlete.

Abstract: A digital timing system for sports competitions in which a large number of participants progress independently and simultaneously on the same track between a starting line and a finish line. This system comprises a starting time memory, a finish time memory, and a register which permits the temporary storing of the times of a predetermined number of events happening nearly simultaneously. The time is furnished by means of an oscillator and decade counters of which the multiplexed output is applied to the register where the information is entered. This information is shortly thereafter transferred to the starting time memory or to the finish time memory, as the case may be. A subtractor unit subtracts the recorded starting time of a selected participant from the real time when it is desired to display the lapsing time of the participant. At the final, the final track time is displayed.

Abstract: An electronic pace timing device whereby a physically perceptible pace timing signal can be repetitively generated, and whereby the repetition frequency of this pace timing signal can be set into the pace timing device as a numeric value, by actuation of external operating members.
