摘要： An oil level sensor for a vehicle includes a receiver tube oriented upright in the oil pan of the vehicle. A level tube is disposed in the receiver tube and below the level tube is a reference tube. A circuit is electrically connected to the tubes for outputting a signal representative of oil level in the oil pan. As the engine oil level decreases within the level tube, the output of the sensor drops. When the engine oil level is below the bottom of the level tube but higher than the top of the reference tube, the output reaches the lowest value. As the engine oil level continuous decreasing (below the top of the reference tube), the output increases for a first circuit configuration (i.e., level with reference tube), and will stay constant for the second configuration level.

摘要： The Solenoid Valve For A Vehicle Carbon Canister includes a housing with an outlet end and a inlet end. A portion of the inlet end of the housing extends around an inlet port formed in the inlet end to create an air inlet tube. Inserted in the outlet end of the housing is an end cap formed with an outlet port. The end cap extends around the outlet port to form an air outlet nipple having an internal portion and an external portion. Formed around the internal portion of the air outlet nipple is an annular cavity. Disposed within the housing is a solenoid mechanism slightly smaller than the housing to form an annular air passage having sufficient area to provide the proper air flow, but also having a thickness small enough to prevent carbon particles from passing through the annular air passage. A continuous air passage is formed by the air inlet tube, the annular air passage, and the air outlet nipple. A plunger is included to block the flow of air through the air outlet nipple. When the plunger is in the open position, the internal geometry of the present invention, such as the thickness of the annular air passage and the drastic increase in volume between the annular air passage and the annular cavity, minimizes contamination by carbon particles.

摘要： A device for determining the viscosity of a liquid has a temperature sensor and a heater disposed in spaced relation within a channel. When the device is immersed in a liquid, the heater heats the liquid and the temperature sensor detects the change in temperature of the liquid in response to heating of the liquid by the heater. A controller coupled with the temperature sensor receives a signal corresponding to the temperature of the liquid and determines an index value corresponding to the change in temperature with respect to time. The index value may be compared with a stored value to evaluate the relative change in viscosity, or it may be used to determine an actual value of viscosity of the liquid.

摘要： An evaporative control valve includes a plunger reciprocable between a valve stop and a valve seat to open and close a controlled port. The plunger has a body, a flexible support member mounted on one end of the body and a resilient tip positioned on the support member for sealing engagement with the valve seat. When the resilient tip of the plunger impacts the valve seat, the flexible support member absorbs substantially all of the force of impact by deflecting in the direction opposite the plunger movement, increasing impact time and reducing noise which may be generated. The resilient tip may be positioned on the flexible support member to further define a stop cushion to further reduce impact of the plunger against the valve stop.

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.

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.
