Portable swing speed analyzer
First Claim
1. A swing speed analyzer for mounting on a hand-held sporting implement having a shaft, comprising:
- a first accelerometer;
a processor that uses an output from the first accelerometer to compute a swing speed;
a housing containing at least the first accelerometer; and
a layer of material adhesively bonded to the housing and interposed between the housing and the shaft and being sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz;
the housing being detachably mountable on the shaft.

Abstract
Provided is a swing speed analyzer for mounting on a swinging implement and comprising a first accelerometer, a processor and a shock attenuator. The processor uses an output from the first accelerometer to compute a swing speed of the swinging implement. The shock attenuator is comprised of a material that is sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz. The material is preferably sized and dimensioned to dampen the impact shock wave from more than 1000 g to less than 500 g. Suitable attenuators can include viscoelastomeric materials such as foam. The swing speed analyzer can advantageously include any of a releasable attachment mechanism, a liquid crystal or other visual display, a second accelerometer, and a strain gauge. The analyzer can advantageously be attached to a golf club, a tennis racket, a baseball bat, or a hockey stick.

14. A hand-held sporting implement having a shaft coupled to a head, comprising:
-
a swing speed analyzer mounted along the shaft, the swing speed analyzer including; a first accelerometer; a processor that uses an output from the first accelerometer to compute a swing speed; a housing containing at least the first accelerometer; and a layer of material adhesively bonded to the housing and interposed between the housing and the shaft and being sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz; the housing being detachably mountable on the shaft; wherein the hand-held sporting implement is configured as at least one of a tennis racket, a baseball bat and a hockey stick.
