A magnetic-based sensor is disclosed which can detect a linear and rotary position of a shaft whose movement is to be measured. Such sensor can operate to yield linear displacement as well as rotation. A position magnet is mounted on the shaft for measuring linear motion. A spirally wound magnet is mounted on the shaft to detect rotational motion. Both of such motions are detected by a single magnetic-based sensor.

Linear and rotary magnetic sensor

A vehicle suspension apparatus according to the invention includes a vehicle suspension strut and a continuous position sensor coupled to the vehicle suspension strut and adapted to provide information indicative of a continuous position of a first portion of the vehicle suspension strut relative to a second portion of the vehicle suspension strut. The continuous position sensor includes a magnet coupled to the first portion of the vehicle suspension strut and a sensing mechanism coupled to the second portion of the vehicle suspension strut and responsive to the magnet to provide an output indicative of the continuous position of the first portion relative to the second portion.

A shock absorber includes a housing having a chamber and a piston slidably disposed in the chamber. A piston rod is connected to the piston and extends out of the housing. The piston rod includes a bore extending longitudinally therein. A magnetostrictive transducer provides an output signal indicative of the piston with respect to the housing. The magnetostrictive transducer includes a magnetostrictive waveguide disposed in the bore and a magnet joined to the housing that is operably coupled to the magnetostrictive waveguide.

A magnetostrictive position sensing device is disclosed where a probe assembly surrounding a waveguide is anchored at one end to the bottom of a tank and terminates in a transducer assembly attached to the top of the tank. The probe assembly compensates for differential coupling between two sections of the probe assembly. The sensing device also includes one or more fluid level floats movably surrounding a portion of the probe.

A graphic display system, including a uniquely designed three or four element structure, forming a semi-graphic display and associated electronic components, such components being mounted in fixed relation to the semi-graphic display, for permitting the use of high density, non-illuminated, semi-graphic displays while retaining the information capability of a full functional graphic. The system includes a frame designed to support structural elements therein and to protect electrical wiring connected between electrical components mounted upon one of the elements, a matrix board. These electrical components include light sources such as light emitting diodes. In a first and second embodiment a circular polarizer screen and a transparent screen are located in front of the matrix board. The circular polarizer, which may be located in direct contact with the transparent screen, is adapted to block incident light transmitted through the polarizer from being reflected. The transparent front screen is sized to protect the polarizer and is embossed, etched or silk screened with semi-graphic information to be displayed by the system. In a third embodiment, only a transparent screen is located in front of the matrix board. The transparent screen is back silk screened in an opaque color, leaving only the semi-graphic portion transparent. The semi-graphic portion may then be back pointed in other colors, leaving transparent portions or holes for the light sources. A photoelectric device may also be used to regulate the intensity of the light sources.

A simple but effective means for employing alternating polarity current in a discrete inputs can system is disclosed. The system permits scanning of a field contact for open mode, closed mode and for the presence or absence of spurious ground contacts.

A deviation indicator interface for simultaneously providing an indication of the deviation of the process value from the set point for each loop of a multi-loop controller is disclosed. The deviation indicator interface includes a plurality of deviation indicators, each deviation indicator providing an indication of the loop deviation of a single loop. Each deviation indicator includes a first, second and third indicator portion. The first indicator portion produces a visible signal whenever the loop process value exceeds the loop set point by at least a first amount, the first amount being adjustable. The second indicator portion produces a visible signal whenever the loop process value is less than the loop set point by at least a second amount, the second amount being adjustable. The third indicator portion produces a visible signal whenever the loop process value (1) is equal to the loop set point, (2) exceeds the loop set point by an amount less than the first amount, or (3) is less than the loop set point by an amount less than the second amount.

Controller deviation indicator

A housing for printed circuit cards or modular assemblies that provides for easy access to the cards or assemblies as well as to interconnection buses and other equipment mounted in the housing is disclosed. The housing includes a cabinet having two fixed, substantially flat plates. The housing further includes a chassis having two substantially rectangular rotating plates. Each fixed plate of the cabinet has a rotating plate of the chassis connected to one side of it by means of two removable hinge pins such that the axis extending from the front to the back of the rotating plate extends perpendicular to the axis extending from the top to the bottom of the fixed plate when both hinge pins are in place. Orientation of the pins is such that by removing one pin, the rotating plate is rotatable about the other pin with respect to the fixed plate. The rectangular rotating plates are connected together by a system of bars forming the chassis on which printed circuit cards and other equipment can be mounted. By using bars of different lengths, any number of cards or assemblies can be accommodated.

Rotatable and expandable chassis and cabinet

A signal conversion system wherein variable amplitude alternating current signals from instrument sensors, which represent the magnitude of measured physical variables or control signals by amplitude modulated alternating current voltage signals, are converted to variable amplitude direct current or voltage signals (FIG. 1). The input signal is filtered for normal mode noise and capacitor isolated for common mode noise. The conversion process also includes magnitude scaling of the variable amplitude input signal, including but not limited to, square root extraction and linear amplitude adjustment.
