Device for detecting speed and position of balls

Abstract

A ball detection device includes a frame with a hitting member connected to a center of the frame. A plurality of detection members are connected between corners of the hitting member and the frame. A CPU is electrically connected to the detection members and a display member. When the hitting member is hit by a ball, the detection members are pulled and send a respective signal according the tension the detection member is applied to the CPU and a corresponding information is displayed on the display member.

What is claimed is:  
     
         1 . A ball detection device comprising: 
 a frame;    a hitting member connected to a center of said frame, a plurality of detection members connected between said hitting member and said frame, and    a CPU electrically connected to said detection members and a display member electrically connected to said CPU.    
     
     
         2 . The device as claimed in  claim 1  further comprising a support structure connected to said frame.  
     
     
         3 . The device as claimed in  claim 1  wherein said hitting member is a sheet of net.  
     
     
         4 . The device as claimed in  claim 3  further comprising a net frame enclosing said sheet of net and said detection members connected to said net frame.  
     
     
         5 . The device as claimed in  claim 1 , wherein said hitting member is a foam plate.  
     
     
         6 . The device as claimed in  claim 1 , wherein each of said detection members includes a core with a coil mounted thereto and a spring, two ends of said spring respectively connected to said frame and said hitting member, an end of said core connected to said hitting member.
