Step counting device and method
First Claim
Patent Images
1. Apparatus for counting the steps taken by a subject wearing said device comprising:
- (a) a shoe,(b) a support member mounted on said shoe, at a location which is subjected to compressive forces while walking,(c) a fatigue life gauge bonded to an area of the support member which is normally relaxed and is strained in response to steps taken on the device by the subject, whereby said fatigue life gauge is strained and the number of steps taken by said subject may be ascertained by measuring the properties of said fatigue life gauge.

Abstract
The number of steps taken while walking are counted by straining a fatigue life gauge to change its electrical resistance each time the device is stepped on by a subject. The change in resistance of the fatigue life gauge is measured to ascertain the approximate number of steps taken.

9. A device for counting the steps taken by a subject wearing said device comprising:
-
(a) a support member, (b) a fatigue life gauge bonded to an area of the support member which is normally relaxed and is strained in response to steps taken on the device by the subject, whereby said fatigue life gauge is strained and the number of steps taken by said subject may be ascertained by measuring the properties of said fatigue life gauge, (c) a housing enclosing said support member, said housing including oppositely facing first and second cups, each of said cups having a circular base and a cylindrical sidewall, said sidewalls being telescopically related to permit relative linear movement between said bases.
