Sports scoring device including a flexible prezoelectric layer resilient layer
First Claim
1. A scoring apparatus for indicating at least one characteristics of an externally applied impact by a sports participant to a deformable object, wherein said characteristic is at least one of velocity, force or energy of said impact, said apparatus comprisingflexible transducer means, responsive to said impact, for providing an analog output, said transducer means comprises a piezoelectric film layer comprises of a piezoelectric material, wherein said transducer means is attached to a first resilient layer of material, wherein said resilient layer is above or below said piezoelectric film layer such that said impact deforms only a portion of said film layer and only a portion of said first resilient layer;
- means, responsive to said analog output, for indicating said one characteristic of said impact, wherein said flexible transducer means of said apparatus comprises an active means for generating an electrical output in response to said impact.

Abstract
Disclosed is a device for generating an analog output signal indicative of an impact to a transducer. The transducer may be mounted on protective equipment utilized in various martial arts fields, such as protective vests and the like or can be mounted on training equipment, such as a heavy bag, striking pad, etc. In a preferred embodiment the transducer is a piezoelectrical signal which is indicative of the amount of deformation. By placing the piezoelectric film on top of a deformable material, in a preferred embodiment sandwiching it in the deformable material, impacts to the deformable material will strain the piezoelectric film generating the signal output. In a further embodiment of the present invention, the piezoelectric transducer is mounted on a target pad and provides an analog output indicative of the characteristics of an object impacting the target pad. For use in the martial arts, the transducer may be connected to a transmitter and remote receiver for providing an indication of the impact at a remote location.
