Abstract

An electronic golf swing analyzing system that uses an array of infrared (IR) and ultrasonic (U/S) sensors, activated by an embedded micro-controller, to capture swing data to accurately calculate the club head'"'"'s velocity, face angle, and swing path at impact. The system also includes a golf swing analyzing software application that receives the data from the analyzer to determine the distance and direction that the ball will travel relative to the target line. During use, the IR sensor base is placed horizontally and the U/S sensor base is positioned vertically. The player selects one of three available practice modes, which determines how the trajectory data for each swing is visually displayed. The player selects a golf club, enters golf ball information, and environmental conditions information. Trajectory results for each swing are graphically displayed relative to the players stated ability level on the computer monitor.

Claims

1. An electronic golf swing analyzer system, comprising:

a. an analyzer including an infrared sensor base and an ultrasonic sensor base, said infrared sensor base includes a hitting area with a center axis with two arrays of infrared sensors located therein used to detect the presence of a club head moving through said hitting area, each said array of infrared sensors being located on opposite sides and equal distance from said center axis, said ultrasonic sensor base being perpendicularly aligned and extending upward above said infrared sensor base, said ultrasonic sensor base including at least two ultrasonic sensors aimed at said hitting area, said ultrasonic sensors being located on opposite sides and equal distance from said center axis, means for activating said ultrasonic sensor on the same side of said center axis as said array of infrared sensors located on the same side of said center axis when a golf club moves across said infrared sensor base;

b. a computer having working memory;

c. means for connecting said analyzer to said computer,

c. a golf swing analyzing software application loaded into said working memory of said computer, said software application capable of using the data from said ultrasonic sensors and said infrared sensors when a golf club is swing is made over said hitting area to determine a golf ball'"'"'s distance, direction, and flight path after impact.

2. The electronic golf swing analyzer system, as recited in claim 1, wherein said means for activating said ultrasonic sensors on the same side of said center axis when said array of infrared sensors are activated is a micro-controller coupled to said infrared sensors that activates said ultrasonic sensor.

3. The electronic golf swing analyzer system, as recited in claim 1, wherein said array of infrared sensors includes one outer infrared sensor and two inner infrared sensors.

4. The electronic golf swing analyzer system, as recited in claim 3 wherein said ultrasonic sensors are automatically activated to produce ultrasonic signals when a golf club moves over said arrays of infrared sensors, said ultrasonic sensors being aimed to transmit an ultrasonic signal and receive a reflected ultrasonic signal from a golf club moving over said array of infrared sensors located on the same side of said center axis.

5. The electronic golf swing analyzer system, as recited in claim 3, wherein the ultrasonic sensor located on one side of said center axis is coupled to said inner infrared sensors to activate said inner infrared sensors.

6. The electronic golf swing analyzer system, as recited in claim 3, wherein each said infrared sensor include an infrared emitter and an infrared photodiode detector.

7. The electronic golf swing analyzer system, as recited in claim 6, wherein said infrared emitter and said infrared photodiode detector are located in a bushing fitted to said infrared support base.

8. The electronic golf swing analyzer system, as recited in claim 7, further including an infrared filter located over said photo-detector.

9. The electronic golf swing analyzer system, as recited in claim 8, further including a lens mounted over said photodiode detector to direct infrared radiation towards said photodetector.

10. The electronic golf swing analyzer system, as recited in claim 1, further including a rubber mat attached over said infrared sensor base.
