摘要： A sensor apparatus and method that can measure either a linear position or an angular position of a device. A linear array of galvanomagnetic sensing elements is fixedly mountable adjacent the device. A target is connectable to the device such that the target moves adjacent a surface of the linear array in response to movement of the device and is shaped so that a magnetic flux density curve resulting from excitation of the sensing elements includes a peak and/or a valley. A first circuit excites each of the sensing elements, and a second circuit measures a magnetic flux density value at each of the sensing elements. A maximum and/or a minimum of the flux density curve indicates the position of the device.

摘要： A magnetoresistor voltage divider includes a bottom layer disposed on a substrate. A middle layer is disposed on the bottom layer. A top layer is disposed on the middle layer. The bottom and top layer are resistive layers and the middle layer is an insulating layer. A common terminal is connected to the bottom layer and the top layer. A reference resistor terminal is connected to the bottom layer only. Moreover, a sensing MR terminal is connected to the top layer only. Accordingly, a sensing MR is established between the common terminal and the sensing MR terminal and a reference resistor is established between the common terminal and the reference resistor terminal. Thus, the sensing MR is stacked on top of the reference resistor.

摘要： An adaptive driver circuit which uses a modified conventional current mirror circuit to provide a current source employing an automatically adjustable current to compensate for decreased SMR device sensitivity at higher temperatures and large air gaps without the need for an active feedback circuit. The adaptive driver circuit according to the present invention is a unique modification of a current mirror circuit in that an SMR device is used as the reference resistor and a fixed resistor in the mirrored circuit to generate an output voltage. A modification is also possible whereby two adaptive driver circuits are used in a differential mode.

摘要： A target wheel sensor assembly includes a target wheel, a magnet, and two or more sensing elements placed therebetween. The magnet and the sensing elements are configured so that as the target wheel rotates each of the sensing elements outputs a respective asymmetric signal relative to the direction of rotation of the target wheel or an object mechanically connected to the wheel. Each of these asymmetric signals is differentially combined with one another to determine the direction of motion of the target wheel, and, if optionally desired, the position of the target wheel.

摘要： A method by which contaminant (soot) content in Diesel engine oil is determined using electrical conductivity measurements of the Diesel oil at a high frequency, or by which contaminant (soot and/or water and/or anitfreeze) content is determined using the ratio of electrical conductivity measurements of the Diesel oil at a high frequency to the electrical conductivity measurements of the Diesel oil at a low frequency. Both the conductivity ratio and the high frequency conductivity are essentially independent of the brand of oil. High frequency is defined to be above 2 MHz whereas low frequency is defined to be D.C. to about 1 kHz.

摘要： A strain sensor includes a load carrying body configured to strain in response to a load applied along a load path. The sensor further includes a magnetostrictive electrical conductor affixed to the body but out of the load path. Application of the load causes the body to strain, which in turn results in a proportional stress being imparted to the magnetostrictive conductor, altering its magnetic permeability. A circuit is coupled to the conductor to detect such changes in permeability, which are indicative of the applied load.
