Abstract

Abstract A device for detecting the forces acting onto a ski binding or a shoe held in such a binding comprising at least one feeler emitting electrical signals in dependency from the occurring forces and an evaluating circuit processing the signals. In order to be able to calculate the state of fatigue of the skier and, if necessary, the condition of the binding, it is provided that an integrator circuit constructed as a counter is connected after the evaluating circuit, which integrator circuit is connected to an indicating device and which can be reset merely by means of a manually operable switching device. The counter can thereby count either signals of the evaluating circuit corresponding with predetermined impacts, or digital signals corresponding with impacts having an energy content, or signals which correspond with those impacts, the rising and dropping speed of which exceed a limit value.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 77 words
In a device for detecting the forces which act onto a ski binding or a shoe held in such a binding, said device having at least one feeler emitting electric signals in dependency from occurring forces and an evaluating circuit processing said signals, the improvement comprising an integrator circuit connected after the evaluating circuit, which integrator circuit is connected to an indicating device and which can be reset only by means of a manually operable switching device.
Claim 2
Dependent Claim 77 words
In a device for detecting the forces which act onto a ski binding or a shoe held in such a binding, said device having at least one feeler emitting electric signals in dependency from occurring forces and an evaluating circuit processing said signals, the improvement comprising an integrator circuit connected after the evaluating circuit, which integrator circuit is connected to an indicating device and which can be reset only by means of a manually operable switching device.
Claim 3
Dependent Claim 49 words
The device according to claim 1, wherein the integrator circuit connected to the evaluating circuit is constructed as a counter which counts the signals of the evaluating circuit, which signals correspond with the impacts acting onto the binding or the shoe, and, if necessary, exceeding an adjustable limit value.
Claim 4
Dependent Claim 47 words
The device according to claim 1, wherein the integrator circuit connected after the evaluating circuit is constructed as a counter which counts the digital signals coming from the evaluating circuit and corresponding with the impacts having an energy content lying above an, if necessary, adjustable limit value.
Claim 5
Dependent Claim 48 words
The device according to claim 1, wherein the integrator circuit connected after the evaluating circuit is constructed as a counter which counts the signals of the evaluating circuit, which signals correspond with those impacts, the rising and dropping speed of which exceeds an, if necessary, adjustable limit value.
Claim 6
Dependent Claim 44 words
The device according to claim 1, wherein the integrator circuit connected after the evaluating circuit is formed by a divider and at least one counter connected after said divider, which counter is connected to an indicating unit and can be read into said unit.
Claim 7
Dependent Claim 89 words
The device according to claim 5, wherein the divider is connected to two parallel connected counters which can be connected through a selector switch selectively with the indicating unit such that one of the counters can be reset with the manually operable switching device which is assembled with said counter and is constructed as a key and the other counter is connected with a digital comparator, the second input of which is connected to a digital limit-value transmitter and the output of which is connected to a control indicator.
