摘要： A magnetostrictive strain sensor (10) includes a magnetostrictive core (12) comprising a magnetostrictive material, such as a nickel-iron alloy, able to conduct a magnetic flux and whose permeability is alterable by application of a strain. A conductive coil (14) is proximate the magnetostrictive core (12) to generate the magnetic flux when electrically excited. A shell (16) surrounds the conductive coil (14) and the magnetostrictive core (12) for providing a conductive return path for the magnetic flux. An excitation source (18) is electrically connected to the conductive coil (14) for electrically exciting the conductive coil (14) with an alternating current having a constant magnitude. An in-phase voltage circuit (22) is electrically connected across the conductive coil (14). The in-phase voltage circuit (22) senses an in-phase voltage that is in-phase with the alternating current. The in-phase voltage varies correspondingly to the strain subjected to the magnetostrictive core (12). A processor (24) is operatively connected to the in-phase voltage circuit (22) to determine the strain applied to said magnetostrictive core (12) by comparing the in-phase voltage to a predetermined relationship between strain and in-phase voltage.

摘要： A harmonic drive linear actuator includes a first annular member defining a longitudinal axis and lying on a plane, which is perpendicular to the longitudinal axis. The first member is relatively flexible along a direction parallel to the plane. A second member is substantially coaxially aligned with the first member to define opposed substantially cylindrical surfaces and are fixed for non-relative rotation about the longitudinal axis. An actuator is provided for flexing the first annular member into at least two spaced-apart points of contact between the opposed surfaces and for sequentially flexing the first member to rotate the at least two points of contact circumferentially about the axis. The first and second surfaces define cooperating thread-forms thereon, which selectively engage to effect controlled, bidirectional relative axial displacement between the members in response to sequential flexure of the first member. The linear actuator can be conjoined with an actuator piston of a vehicle brake caliper assembly.

A pair of accelerometers sense relative acceleration across the mount between the engine and the frame and generate a relative acceleration signal. A control unit is electrically connected to the accelerometers. The control unit is adapted to generate an electronic control signal in response to the relative acceleration signal. The control device is responsive to the electric control signal for controlling the damping force of the hydraulic mount.

摘要： A hydraulic engine mount includes an orifice track formed in a partition between an elastomer body and a base member of the mount, the partition being formed by two separable orifice plates. An annular fluid filled tuning chamber is disposed adjacent the orifice track and separated therefrom by a flexible membrane. An actuator is in communication with the tuning chamber for forcing pressure fluid into or out of the chamber to selectively deflect or distend the membrane to modify the cross sectional area of the orifice track and the vibration damping characteristics of the mount.
