摘要： A combustible gas sensor that uses a resistively heated, noble metal-coated, micromachined polycrystalline Si filament to calorimetrically detect the presence and concentration of combustible gases. The filaments tested to date are 2 .mu.m thick.times.10 .mu.m wide.times.100, 250, 500, or 1000 .mu.m-long polycrystalline Si; some are overcoated with a 0.25 .mu.m-thick protective CVD Si.sub.3 N.sub.4 layer. A thin catalytic Pt film was deposited by CVD from the precursor Pt(acac).sub.2 onto microfilaments resistively heated to approximately 500.degree. C.; Pt deposits only on the hot filament. Using a constant-resistance-mode feedback circuit, Pt-coated filaments operating at ca. 300.degree. C. (35 mW input power) respond linearly, in terms of the change in supply current required to maintain constant resistance (temperature), to H.sub.2 concentrations between 100 ppm and 1% in an 80/20 N.sub.2 /O.sub.2 mixture. Other catalytic materials can also be used.

摘要： An arc magnet assembly with a virtual radial magnetization is established by placing a series of small trapezoidal-shaped magnet segments having axial magnetizations side by side to form an arc.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A contactless latch engagement detector for a mechanical fastening system operating on the principle of magnetosensitivity. A magnetosensitive switch composed of a magnetosensitive device and at least one biasing magnet adjacent the magnetosensitive device are located in a buckle. Within or external to the buckle is an electronic circuit for driving the magnetosensitive device, and a flux bar composed of a ferromagnetic material having a high magnetic permeability is associated with a movable component of the system. In operation, the electronic circuit drives the magnetosensitive device, wherein its output is responsive to position of the flux bar relative to the magnetosensitive device. The flux bar moves responsive to position of a tongue within the buckle, whereby the fastened state of the mechanical (ie., seat belt) fastening system is detected when a predetermined output occurs.

摘要： 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.

摘要： 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.
