摘要： A movement actuator includes an elongate filament made of a flexible material, and a strip of shape memory alloy disposed on the surface of one side of the filament. The shape memory alloy is responsive to actuation signals, heat or electrical signals, for changing its shape and when its shape changes, it causes the filament to move, i.e., bend, to accommodate the change in shape of the alloy. Also included is a signal supply device for selectively applying heat signals or electrical current to the strip of shape memory alloy to cause the alloy to change its shape and cause the filament to bend. Other patterns for the shape memory alloy could be disposed on the filament to cause other kinds of movements. For example, a helical pattern of the shape memory alloy about the filament would cause the filament to twist when the helical pattern were caused to shorten or lengthen.

摘要： The present invention is an inertial rate of turn sensor of the vibratory type employing force feed back techniques for maintaining the free end of a cantilever in a nulled lineal path, constant with respect to the casing of the instrument. The current required to maintain the constant lineal path is then a measure of the amplitude of the rate of turn of the case and the phase sense of that current defines the sense of rotation of the case and therefor of the craft.

摘要： A sensor system for sensing movement comprises a rod anchored at one end to a base and plurality of strain gauges circumferentially disposed about the rod. The free end of the rod may be subject to forces in various directions. The strain gauges produce signals whose magnitudes are an indication of the degree of strain occurring at the location of the strain gauges. The use of three or more strain gauges spaced circumferentially about the rod provide both direction and degree of bend of the rod.

摘要： Controlled bending movement of a flexible elongate rod or filament in response to a bend signal indicative of a desired amount of bending is effected by a strip of shape-changing material disposed on a first side of an elongate rod element, the shape changing material changing shape in response to an actuation signal, thereby causing the filament element to bend, and a sensor including a strain gauge disposed on the rod element on a second side opposite the first side, said sensor sensing the amount of bend in the rod element from strain indicated, and a feedback control comparing the amount of bend of the filament sensed to a desired amount of bend defined by said bend signal and altering the actuation signal as required to make the amount of bend sensed the same as the amount of bend desired.

摘要： A system for determining acceleration by measuring the movement of a rod within a housing. The rod is an elongate flexible rod disposed in the housing with one end being attached to the housing and the other end being free to move when the housing is accelerated. Movement of the rod is measured with field detectors disposed on an inside wall of the housing. The field detectors are used for determining the direction and degree of movement of the rod when the housing is accelerated.

摘要： Methods and apparatus for measuring gravitational and inertial forces, magnetic fields, or wave or radiant energy acting on an object or fluid in space provide an electric tunneling current through a gap between an electrode and that object or fluid in space and vary that gap with any selected one of such forces, magnetic fields, or wave or radiant energy acting on that object or fluid. These methods and apparatus sense a corresponding variation in an electric property of that gap and determine the latter force, magnetic fields, or wave or radiant energy in response to that corresponding variation, and thereby sense or measure such parameters as acceleration, position, particle mass, velocity, magnetic field strength, presence or direction, or wave or radiant energy intensity, presence or direction.
