Athletic monitoring device
First Claim
1. A wrist-worn bowling monitoring device for monitoring the bowling motion of a bowler, comprising:
- sensor means for sensing the accleration of the device in three orthogonal axes of motion and providing data representative of the acceleration of the device in the three axes of motion;
first computation means for computing values equal to the square root of the sum of the squares of the acceleration data of each direction;
first comparison means for comparing each of said computed values the to a predetermined threshold;
second computation means for adding each computed value which exceeds the predetermined threshold to provide a total;
second comparison means responsive to the first comparison means for comparing the computed total to a predetermined range if a computed value is found to be less than the threshold;
signal means for providing a first signal if the computed total exceeds the predetermined range and a second signal distinguishable from the first signal if the computed total is less than the predetermined range; and
bowler operable input means for inputting a desired total value and a window value, wherein the predetermined range is defined as the desired total value less one-half the window value to the desired total value plus one-half the window value.

Abstract
An athletic monitoring device for attachment to a portion of an athlete'"'"'body or to athletic equipment. The device measures a predetermined parameter of the motion of the device while in use and compares the measured parameter to a predetermined range. Intensity of acceleration is measured by taking the square root of the sum of the squares of acceleration data for each of the three axes of motion. This value is compared to a threshold value. If greater than the threshold value, the square root value is stored and added to a second measured intensity value. In this manner, a sum of intensity values throughout a stroke is calculated. If the sum of intensities is above or below a predetermined range, appropriate signalling will so indicate.
