US 2014/0152236 A1 · DEVICES AND METHODS FOR DETECTING RATES OF CHANGE OF TORQUE

Abstract

Sensors for outputting signals indicative of a rate of change of torque experienced by a magnetized member in response to a change in torque experienced by the member are described. Such sensors include at least one sense element capable of detecting a change in a magnetic parameter of a magnetized region of the member positioned proximate to the sense element in response to a change in torque applied to the member. Devices for detecting and/or measuring rates of changes in or of torque that employ one or more of these sensors are also described, as are various applications for such devices.

Dependent claims

A sensor for detecting a rate of change of torque experienced by a member capable of transmitting torque, comprising:

a. a sense element configured to output a signal indicative of a rate of change in torque experienced by a member carrying or subjected to a time-varying torque, wherein the sense element is capable of detecting a change in a magnetic parameter of a magnetized region of the member positioned proximate to the sense element in response to a change in torque experienced by the member;
and at least one of a processor according to part (b), below, or a memory according to part (c), below;
and
b. a processor operatively associated with the sense element and configured to process signals output from the sense element to determine a rate of change of torque experienced by the member;
or
c. a memory operatively associated with the sense element and configured to store data representing information in the signal output from the sense element.
