Golf putter assembly

Abstract

A golf putter assembly includes a putter including a head, a display unit disposed in the putter, and a detecting unit disposed in the putter and electrically coupled to the display unit. The detecting unit is operable to detect and record a stationary starting position of a golf ball. The detecting unit is further operable to detect, during a practice swing, an instantaneous speed of the head as the head moves past the starting position, and to calculate what would be an initial speed of the golf ball if the golf ball was actually hit by the head with reference to the instantaneous speed of the head detected thereby. The detecting unit further performs control such that the initial speed of the golf ball as calculated is displayed on the display unit.

1 . A golf putter assembly, comprising:
 a putter including a head;   a display unit disposed in said putter; and   a detecting unit disposed in said putter and electrically coupled to said display unit, said detecting unit being operable to detect and record a stationary starting position of a golf ball, said detecting unit being further operable to detect, during a practice swing, an instantaneous speed of said head as said head moves past the starting position of the golf ball, said detecting unit being further operable to calculate what would be an initial speed of the golf ball if the golf ball was actually hit by said head with reference to the instantaneous speed of said head detected thereby, said detecting unit further performing control such that the initial speed of the golf ball as calculated is displayed on said display unit.   
   
   
       2 . The golf putter assembly of  claim 1 , wherein said detecting unit includes a detector for detecting the instantaneous speed of said head, said detector being based on MEMS (Micro-Electro-Mechanical Systems) technology. 
   
   
       3 . The golf putter assembly of  claim 1 , wherein said detecting unit is further operable to determine a ground slope at the starting position of the golf ball. 
   
   
       4 . The golf putter assembly of  claim 3 , further comprising a user input unit disposed on said putter and electrically coupled to said detecting unit, said user input unit allowing input of a putting green speed, said detecting unit being further operable to calculate what would be a rolling distance of the golf ball if the golf ball was actually hit by said head with reference to the putting green speed, the instantaneous speed of said head, and the ground slope, said detecting unit further performing control such that the rolling distance of the golf ball as calculated is displayed on said display unit. 
   
   
       5 . The golf putter assembly of  claim 4 , wherein said putter further includes a grip, and a shaft that interconnects said head and said grip, said user input unit being disposed on said grip of said putter. 
   
   
       6 . The golf putter assembly of  claim 1 , further comprising a power supply unit disposed in said putter, and electrically coupled to said detecting unit and said display unit, said power supply unit providing electricity to said detecting unit and said display unit. 
   
   
       7 . The golf putter assembly of  claim 6 , wherein said power supply unit includes a solar cell disposed in, and at least partly exposed from, said putter. 
   
   
       8 . The golf putter assembly of  claim 1 , wherein said display unit is disposed in said head. 
   
   
       9 . The golf putter assembly of  claim 1 , further comprising a user input unit disposed on said putter, and electrically coupled to said display unit and said detecting unit, said user input unit including a switch for controlling On and Off states of said display unit and said detecting unit. 
   
   
       10 . The golf putter assembly of  claim 9 , wherein said switch of said user input unit further allows activation of said detecting unit for detecting and recording the starting position of the golf ball. 
   
   
       11 . The golf putter assembly of  claim 1 , wherein said detecting unit calculates the initial speed of the golf ball with reference to the instantaneous speed of said head and at least one pre-established parameter selected from the weight of said head, the weight of the golf ball, and the coefficient of elasticity of the golf ball.
