ABSTRACT:
A piezoelectric motion detector is disclosed. The device is particularly suitable for use in analyzing a golf ball when hit from a golf tee. A piezoelectric film is affixed to the bottom of a tee having a base. A signal generated by the piezoelectric film is amplified and is used, for example, to open a camera shutter and initiate a sequence of light flashes.
