摘要： A method for compensating the output of an angular position sensor assembly includes placing a first magnetic field sensor such that it is oriented ninety degrees from a second magnetic field sensor. A magnet is placed so that it is equidistant from the sensors. The magnet is rotated, and as it rotates, the signals output by the sensors are sinusoidal waves that are out of phase with each other by ninety degrees (90°). Accordingly, the signals can be squared and summed to determined a temperature compensation signal.

摘要： A method for compensating signals from an absolute angular position sensor assembly is used in conjunction with an absolute angular position sensor assembly having an input gear coupled to a rotating shaft. The input gear is meshed with an output gear that rotates as the input gear and the shaft rotate. The sensor assembly includes an input gear sensor and an output gear sensor placed in proximity to the input gear and output gear, respectively. The gears are configured so as to be sensed by the sensors. The method includes determining an angular position compensation value that is used to adjust an absolute position of the input gear, which in turn is used to compute the absolute position of the rotating shaft. The angular position compensation value for the revolution N+1 is determined as APCVN+1=(APRSN−AAPIGN)/&agr;+APCVN, wherein APCVN+1 is the angular position compensation value for the revolution N+1, APRSN is the angular position of the rotating shaft for the revolution N, AAPIGN is the adjusted angular position of the input gear for the revolution N, &agr; is a compensation factor that is greater than one, and APCVN is angular position compensation value for the revolution N.

摘要： A transmission clutch position sensor includes two Hall sensors located at opposite ends of a flux concentrator outside the casing of the transmission to sense a magnetic field generated by a magnet attached to the clutch piston. To reduce sensitivity to magnet-to-sensor gap tolerances, a ratio of the voltage of one Hall sensor to the sum of the voltages from both Hall sensors is used to correlate to the piston and, hence, clutch 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 capacitive pressure sensor includes a electrically conductive, generally piston shaped diaphragm with a flexible base wall configured to deflect under pressure. The diaphragm is generally U-shaped in cross section. The base wall includes an upper, flat sensing surface which acts as a capacitive electrode. The diaphragm further includes a step around a radially-outermost perimeter which is elevated from the flat sensing surface. A sensing electrode body is located on top of the step and creates a capacitive sensing cavity between the sensing surface and the bottom surface of the electrode body. On the bottom surface of the electrode body is formed a center, circular electrode and a ring electrode that surrounds the center electrode. The center electrode and the sensing surface form a variable capacitor which changes with pressure and the ring electrode and the sensing surface form a reference capacitor. A circuit determines a differential capacitance between the variable capacitor and the reference capacitor and generates a pressure signal indicative of the fluid pressure applied to the diaphragm. A spring ring holds the sensing electrode body against the diaphragm when assembled. The diaphragm can be a machined metal part or a sheet metal cup. The sensing electrodes and signal generating circuit can take the form of a hybrid circuit.

摘要： MOSFETs are provided to connect the sensor input terminals of a ratiometric output sensor to a pair of power terminals, and the gate of each MOSFET is coupled to the opposite power terminal so that both MOSFETs are rendered conducting to power the sensor when a supply voltage of a predetermined polarity is connected across the power terminals but one of the MOSFETs is rendered non-conducting when a voltage of the opposite polarity is so applied. The MOSFET that is rendered non-conducting is oriented so that any internal source-drain diode does not bypass current around the MOSFET when voltage of the opposite polarity is applied. Optionally, over-voltage protection is provided by an input voltage sensor controlling the other MOSFET through a third MOSFET.

摘要： A viscosity measurement apparatus, or viscometer, including a fluid flow channel, a heating element disposed at least around an exterior portion of the fluid flow channel near an inlet end, and a temperature sensor disposed within the fluid flow channel downstream from the heating element. The viscometer may also include a thermally insulating jacket disposed around the heating element and the fluid flow channel. A method of measuring viscosity with the viscometer includes immersing a fluid flow channel in the fluid, heating a portion of the fluid in the fluid flow channel near the inlet end of the fluid flow channel, and measuring a temperature of the fluid in the fluid flow channel at a position downstream from the inlet end of the fluid flow channel. The method further includes recording temperature changes of the fluid for a time period and comparing recorded temperature change characteristics to known fluid viscosities to determine viscosity.
