Sport or game goal post visual aid system and method for using the same

Abstract

A sport or game goal visual aid system includes a visible light assembly that provide a pair of angular visible light coverages next to the goal post (only outside of the goal opening) or a visible light mesh/grid only over the goal opening.

1 . A sport or game goal visual aid system comprising: 
 a sport or game goal with a frame defining a goal opening; and    at least one visible light emitter mounted on the frame for providing crisscrossing visual light beams into a visual light mesh or grid only covering the opening.    
   
   
       2 . The sport or game goal visual aid system according to  claim 1 , further comprising a visible light detector mounted on the opposite side of the frame corresponding to each of said emitter for receiving the light beams thereby determining whether a moving playing object passing via the opening.  
   
   
       3 . The sport or game goal visual aid system according to  claim 1 , further comprising an audible sound device to be activated by the receivers when the receivers determine the moving playing object just passed via the opening.  
   
   
       4 . The sport or game goal visual aid system according to  claim 1 , further comprising a microprocessor programmed to respond to a signal from the receives to score points, wherein the moving playing object interrupts the visible light beams to be received by the receivers such that the signal is delivered from the receiver to the microprocessor.  
   
   
       5 . The sport or game goal visual aid system according to  claim 1 , wherein the emitter is a solid state laser, an ion gas laser, a visible light LED, a laser diode, or an HeNe laser.  
   
   
       6 . The sport or game goal visual aid system according to  claim 1 , wherein the sport or game is football, soccer, hockey, rugby, ice hockey, roller hockey, field hockey, team handball, water polo, and lacrosse.  
   
   
       7 . The sport or game goal visual aid system according to  claim 1 , further comprising a net attached to the frame.  
   
   
       8 . The sport or game goal visual aid system according to  claim 7 , wherein the net is made of a translucent material.  
   
   
       9 . The sport or game goal visual aid system according to  claim 1 , wherein said at least one visible light emitter includes at least one pair of visible light emitters mounted on two opposite sides of the frame.  
   
   
       10 . The sport or game goal visual aid system according to  claim 9 , wherein the emitters are symmetrically mounted on the frame.  
   
   
       11 . A method for providing visual aids to a sport or game goal with a frame defining a goal opening, comprising: 
 generating crisscrossing visual light beams into a visual light mesh or grid to cover only the opening.    
   
   
       12 . A method according to  claim 11 , further comprising: 
 sensing interruption of said crisscrossing visual light beams by a playing object of the sport or the game passing over the opening.    
   
   
       13 . A method according to  claim 12 , further comprising: 
 activating an audible sound when said interruption of said crisscrossing visual light beams is sensed.
