A self-compensating control circuit for use with a magneto-resistive sensor. The control circuit includes a first stage amplification and offset function that removes a DC component from the input signal and maximizes an AC component of the input signal within the dynamic range of the control circuit. Subsequent stages remove the remaining DC component, if any, and provide suitable additional amplification. A comparator provides a digital output based on the processed input signal and a threshold signal.

A non-contacting, magnet-based, rotary and linear travel absolute position sensor each include a stationary galvanomagnetic sensing element disposed in an air gap or slot of a movable magnet/flux concentrator assembly. The assembly has a first flux concentrator comprising ferromagnetic material having opposing magnet ends, and a second flux concentrator also comprising ferromagnetic material having opposing magnet ends but that is spaced apart from the first flux concentrator by a pair of magnets to form the air gap or slot. The magnet ends of each flux concentrator have a respective magnet area configured to engage a corresponding magnet and is configured in size and shape to cover the magnet. Additionally, the flux concentrators are configured in geometry to decrease in cross-sectional area from the inboard side of the magnet ends towards the center region of the concentrators, specifically the center of travel together provide improved linearity and signal to noise ratio of the output position signal.

Sensor and method for encoding and detecting a plurality of discrete positions are provided. The sensor comprises an array of electromagnetic assemblies. Each assembly may be made up of a magnet, and a flux-sensing switch electromagnetically coupable to the magnet to generate a signal having a respective logical state in response to the presence or absence of flux from the magnet. A flux mask is movably interposed between each magnet and flux-sensing switch. The flux mask includes a window array configured to pass or block flux from each magnet. The window array is further configured so that each flux-sensing switch can generate in response to whether or not flux passes therethrough, a signal set encoded to uniquely identify each of the discrete positions as the flux mask is set at any of the discrete positions.

A camshaft phaser system includes an oil control spool valve having two opposing springs to center the spool at a rest position to lock the phaser rotor by blocking supply/vent to both the C1 and C2 chambers, obviating a conventional locking pin mechanism. A double-acting solenoid actuator moves the spool to first and second positions, supplying or venting C1 and C2, respectively. The rotor may be locked hydraulically at any position between full advance and full retard. A system for monitoring the rotational positions of the crankshaft and camshaft includes magnets disposed on opposite sides of the shaft axis. A magnetic sensing element senses the rotational direction of the magnetic field for each position of the shaft. An engine control module uses the position signal and an algorithm to lock the rotor at a desired position.

A fuel sensor includes a cylindrical, one-piece plastic body that has an inlet, an outlet and a fuel passage in between. The body further includes three sensing, thin-walled plate holders that extend from the cylindrical body into and across the fuel passage. Three parallel sensing plates are disposed in the holders for use in forming a pair of parallel plate devices. The thin-walled plate holders surrounding the plates provide isolation of the plates from contact with the fuel. The body also includes a cavity to house a printed circuit board (PCB), which includes signal processing circuitry. The PCB is also isolated from exposure to the fuel. The sensing plates have leads that extend into the cavity for connection to the PCB. An interface connector for connection to an engine controller is also provided. The sensor achieves isolation from exposure to fuel without the use of any coatings.

A fuel level sensor assembly includes a magnetic sensor for sensing a magnetic field corresponding to fuel level. The magnetic sensor includes a magnetic sensing element packaged within a hermetically sealed non-magnetic metal case. The magnetic sensing element may be a Hall effect, giant magnetoresistive (GMR), or anisotropic magnetoresistive (AMR) sensor. The case may correspond to the dimensions of a standard transistor outline (TO) package such as TO-3, TO-5, TO-8, TO-18, TO-39, TO-46, TO-52, or TO-72.

A magnetostrictive sensor for outputting a signal representative of torque on a shaft includes one or more excitation coils that generate magnetic flux which permeates the shaft and pickup coils that detect the flux after the flux passes through the shaft. Torque on the shaft affects the magnetic flux passing through the shaft. A coupling member such as plural rollers or powder metal poles are disposed in the flux path and touch the shaft such that no air gap exists in the flux path. Consequently, the sensor is comparatively sensitive, and is not unduly effected by shaft run-out.

A sensing apparatus for determining a property of a fuel such as a gasoline and ethanol blend known as flex fuel includes an acetal plastic tube with an inlet, an outlet and a fuel passage in between. One property of the fuel is a dielectric constant. A pair of sensing plates are placed on opposite sides of the tube leaving the fuel passage unobstructed. A processing circuit on a printed circuit board (PCB) is located near to and is connected with the sensing plates. The circuit applies an excitation signal, senses a capacitance, and generates an output signal indicative of a property of the fuel. The sensed capacitance will increase with increasing concentration of ethanol in the fuel flowing through the passage. A shield for reducing EMI surrounds and encloses the sensing plates and the PCB. An interface connector allows the sensing apparatus to output the capacitance indicative signal to an engine controller or the like.
