Abstract
Abstract This repeatable golf swing teaching device tracks real time movement of a golf club head during a swing using a light gun attached to or inside the club head interacting with light sensors on a base and an upright panels to indicate path of movement. When a desired swing path is achieved the paths may be locked in a computer and the desired swing path thereafter compared with subsequent swings with an alarm activated as a subsequent swing deviates from the desired swing path.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
248 words
A repeatable golf swing teaching device comprising: a) a base platform, a vertical side panel, and vertical back panel; b) a pressure sensitive pad containing multiple pressure sensors on said base platform; c) multiple light sensor means and multiple green and multiple red display lights in a range of swing paths in said base platform, said vertical panel and said back panel; d) a manually operable switch, a battery, a battery powered light gun and fiber optic cable fitted inside a golf club with said fiber optic cable terminating in a lower plane of a head of said golf club; e) a computer communicating with said multiple pressure sensor means and said multiple light sensor means and said multiple display lights in said base platform, said vertical side panel and said vertical back panel; said computer acting to: 1) light a red light in said pressure sensitive pad if signals received from said multiple pressure sensors differ from a previously chosen pattern; 2) light a portion of said multiple red display lights indicating light path of incident light from said fiber optic cable in said head of said golf club as said golf club is swung at a ball; 3) record wing path of each swing and to activate an alarm if said swing path differs markedly from a pre-chosen swing path; 4) to activate a portion of said multiple green display lights to form said pre-chosen swing paths when a save and permanent display command is entered.
Claim 2
Dependent Claim

A repeatable golf swing teaching device comprising: a) a base platform, a vertical side panel, and vertical back panel; b) a pressure sensitive pad containing multiple pressure sensors on said base platform; c) multiple light sensor means and multiple green and multiple red display lights in a range of swing paths in said base platform, said vertical panel and said back panel; d) a manually operable switch, a battery, a battery powered light gun and fiber optic cable fitted inside a golf club with said fiber optic cable terminating in a lower plane of a head of said golf club; e) a computer communicating with said multiple pressure sensor means and said multiple light sensor means and said multiple display lights in said base platform, said vertical side panel and said vertical back panel; said computer acting to: 1) light a red light in said pressure sensitive pad if signals received from said multiple pressure sensors differ from a previously chosen pattern; 2) light a portion of said multiple red display lights indicating light path of incident light from said fiber optic cable in said head of said golf club as said golf club is swung at a ball; 3) record wing path of each swing and to activate an alarm if said swing path differs markedly from a pre-chosen swing path; 4) to activate a portion of said multiple green display lights to form said pre-chosen swing paths when a save and permanent display command is entered.
Claim 3
Dependent Claim
29 words
A repeatable golf swing teaching device as in claim 1 further comprising a computer output indicating elapsed time from start of a backswing to impact on a golf ball.
Claim 4
Dependent Claim
26 words
A repeatable golf swing teaching device as in claim 1 further comprising computer output of analysis of each golf swing as compared to said pre-chosen swing.
Claim 5
Dependent Claim
29 words
A repeatable golf swing teaching device as in claim 1 further comprising computer output indicating deviation from a standard of weight shift of said golf student during a swing.
Claim 6
Dependent Claim
253 words
A repeatable golf swing teaching device comprising: a) a base platform, a vertical side panel and vertical back panel; b) a pressure sensitive pad containing multiple pressure sensors on said base platform; c) multiple light sensor means and multiple green and multiple red display lights in a range of swing paths in said base platform, said vertical panel and said back panel; d) a manually operable switch, a battery, a battery powered light gun and fiber optic cable with means to securely fasten said switch, said battery, said light gun and said fiber optic cable to a golf club; said fiber optic cable terminating to point directly downward parallel to a shaft of said golf club; e) a computer communicating with said multiple light sensor means and said multiple pressure sensors and said multiple display lights in said base platform, said vertical side panel and said vertical back panel; said computer acting to: 1) light a red light in said pressure sensitive pad if signals received from said multiple pressure sensors differ from a previously chosen pattern; (2) light a portion of said multiple red display lights indicating light path of incident light from said fiber optic cable on said shaft as said golf; 3) record swing path of each swing and to activate an alarm if said swing path differs markedly from a pre-chosen swing path; 4) to activate a portion of said multiple green display lights to form said pre-chosen swing path when a save and permanent display command is entered.
Claim 7
Dependent Claim
253 words
A repeatable golf swing teaching device comprising: a) a base platform, a vertical side panel and vertical back panel; b) a pressure sensitive pad containing multiple pressure sensors on said base platform; c) multiple light sensor means and multiple green and multiple red display lights in a range of swing paths in said base platform, said vertical panel and said back panel; d) a manually operable switch, a battery, a battery powered light gun and fiber optic cable with means to securely fasten said switch, said battery, said light gun and said fiber optic cable to a golf club; said fiber optic cable terminating to point directly downward parallel to a shaft of said golf club; e) a computer communicating with said multiple light sensor means and said multiple pressure sensors and said multiple display lights in said base platform, said vertical side panel and said vertical back panel; said computer acting to: 1) light a red light in said pressure sensitive pad if signals received from said multiple pressure sensors differ from a previously chosen pattern; (2) light a portion of said multiple red display lights indicating light path of incident light from said fiber optic cable on said shaft as said golf; 3) record swing path of each swing and to activate an alarm if said swing path differs markedly from a pre-chosen swing path; 4) to activate a portion of said multiple green display lights to form said pre-chosen swing path when a save and permanent display command is entered.
