Abstract: A magnetostrictive sensor (200) to sense force (212) or torque applied to a structural element (204) to which the magnetostrictive sensor is non-invasively attached by a fixed, intimate contact therewith. The sensor consists of a magnetostrictive layer (210) in intimate contact with a coil (206) excited source of magnetic flux. A force or torque applied to the structural element produces a stress transferred to the magnetostrictive layer, thereby varying the magnetic permeability of the magnetostrictive layer. The change in the magnetic flux (224) produces a change in the inductance and impedance of the coil, and thereby a detectable change in the voltage V' s across the coil.

Abstract: A rotary position sensor (20, 20 ) featuring a magnetized rotor (10, 10 ) which produces a magnetic flux density that varies sinusoidally with respect to the angular position of the rotor, which may be either a selectively magnetized ring (10 ) or disk (10). The magnetic flux density produced by the rotor is measured by a sensor (30, 30a) that responds in a linear fashion to the magnitude of the radial component of the magnetic flux density. Typical embodiments would use magnetic flux density sensors, as for example either linear Hall sensors or magnetoresistive type sensors. The measured magnetic flux densities are then used as in a traditional resolver to compute position or used to directly generate control signals to operate, for example, a motor.

Abstract: A magneto-rheological damping device comprises a piston (112) and a case element (116), both capable of acting to carry a magnetic flux. A passage (146) exists between the piston and the case element, and an amount of MR fluid (144) is positioned between the piston and the case element to flow within the passage.
A first magnetic flux generator and a second magnetic flux generator cooperate to generate a net flux that is disposed to act upon the MR fluid in the passage to affect the flow of fluid in the passage.
One of the flux generators comprises a permanent magnet (150) to generate a bias flux between the piston and the case element, and the other flux generator comprises a means (134) for providing a controllable magnetic flux between the piston and the case element.
