摘要： An apparatus monitors at least one fuel quality characteristic of fuel passing through a fuel delivery system of a motor vehicle. The apparatus includes a fuel rail assembly connectable to the fuel delivery system of the motor vehicle. A fuel rail assembly has at least one housing associated with either a pressure regulator or an accumulator. A sensor is associated with the fuel rail assembly for measuring at least one characteristic of fuel quality of fuel passing through the fuel rail assembly.

摘要： A system for measuring oil condition in large engines includes a bypass valve that is installed in a lubrication system along a fluid line between an oil pan and an engine. The bypass valve communicates with a measurement chamber and when energized by a control module, the bypass valve diverts oil from the lubrication system to the measurement chamber. An oil condition sensor is disposed within the measurement chamber and is used to determine the condition of the oil that is diverted to the chamber. After the condition of the oil is determined, the bypass valve is energized to release the oil from the measurement chamber back into the lubrication system.

摘要： An actuator housing isolator plate is used in an actuator array having two or more actuator assemblies connected to each other by a flexible circuit. The isolator plate prevents the actuator housings, in which the actuator assemblies are disposed, from contacting the flexible circuit. Thus, the likelihood of the actuator housings shorting out the flexible circuit is eliminated. The isolator plate further includes isolator posts that prevent the flexible circuit from contacting itself when it is folded over on top of the actuator housings.

摘要： A steering column differential angle position sensor includes an upper target wheel and a lower target wheel. Each target wheel forms a plurality of similarly shaped slots that are equally spaced radially around the target wheels. Two receiver coils and a excitation coil are coaxially aligned with the target wheels. A hollow housing surrounds the target wheels and the coils. The excitation coil generates an alternating current magnetic field around itself, and this alternating current magnetic field generates eddy current in the target wheels. The receiver coils receive an alternating current signal that is a combination of the alternating current magnetic field generated by the excitation coil and the eddy current. The receiver coils sense changes in the alternating current signal due to differential slot alignment of the target wheels, and hence, the torque on a steering column that is mechanically coupled to the sensor.

摘要： A steering column differential angle position sensor includes an upper flux shutter and a lower flux shutter, both of which form a plurality of similarly shaped openings. Receiver and transmitter coils are coaxially aligned with the shutters. The transmitter coil provides a magnetic field around the shutters, with changes in the field being sensed by the receiver coil upon differential motion of the flux shutters. Using the output of the receiver coil, the torque on a steering column that is mechanically coupled to the shutters can be obtained.

摘要： A method for altering engine ignition timing includes removing a centered gear tooth sensor from an engine. The centered gear tooth sensor is replaced with an offset gear tooth sensor. The offset gear tooth sensor includes a sensing element that forms a sensing angle, &agr;, with respect to a center diametric axis defined by a target wheel. The engine ignition timing is altered by an angular amount equal to the sensing angle, &agr;, of the sensing element.

摘要： Linear velocity sensor and method for reducing non-linearity in the output signal of the sensor are provided. The sensor comprises a ferromagnetic housing including an opening. The sensor further comprises a spool disposed in the housing. The spool includes a bore for receiving a slidable ferromagnetic rod. The ferromagnetic rod may be extendable through the opening in the housing. A magnet is mounted at the one end of the rod distal from the opening when the rod is substantially inserted in the bore. A coil is wound on the spool. The number of turns of the coil is arranged to taperingly increase as the coil progresses from an end of the spool proximate the opening in the housing to the opposite end of the spool. The tapering arrangement for the number of turns of the coil is selected to reduce non-linearity of an output signal of the coil indicative of linear velocity.

摘要： An oil level/condition sensor includes a first level sensing tube, a common tube, and a second level sensing tube. The tubes are concentric to each other around a central axis. Moreover, the tubes are separated by plastic spacers which insulate the level sensing tubes from the common tube and maintain the concentricity of the tubes. Installed in the end of the first level sensing tube is a coupling/plug and disposed around the coupling/plug is a first condition sensing tube. The coupling/plug insulates the first level sensing tube from the first condition sensing tube and prevents fluid communication therebetween. A second condition sensing tube is attached to the second level sensing tube around the common tube and the first condition sensing tube. A ring-shaped insulator electrically isolates the second condition sensing tube from the second level sensing tube. The multiple tube configuration provides increased sensing surface area without increasing the length of the sensor or dramatically increasing the overall diameter of the sensor package. As such, the increased sensing surface area increases the signal strength and the accuracy of the sensor. Thus, the sensor is used in relatively shallow oil pans where the length of the sensor is constrained by the depth of the oil pan.

摘要： An analog angle encoder having a simply constructed magnet assembly, wherein rotation of a magnetic field relative to a magnetosensitive device provides a varying output of the magnetosensitive device that varies sinusoidally with the angle of relative rotation. The simply constructed magnet assembly is of a closed-path geometry composed of a single piece of magnetic material wherein only a first portion thereof is magnetized for providing the aforesaid magnetic field for the sensor. The remaining portion of the magnet material (the second portion) remains unmagnetized and does not substantially influence the magnetic field produced by the first portion any more than, for example, air would cause.

摘要： A flexible circuit film oil sensor includes a flexible circuit film surrounded by a flexible border. A core support flap and a weld flap are attached to opposite ends of the flexible border. The flexible circuit film includes an oil level sensing electrode surface, an oil condition sensing electrode surface, a resistive temperature device, and a common electrode surface. The flexible circuit film engine oil sensor is wrapped around a core structure so that a spiral oil chamber is formed. Accordingly, the spiral oil chamber is at least partially filled with oil and electrical signals are provided across the electrode surfaces in order to monitor the level and condition of oil within the sensor. Additionally, the resistive temperature device provides a signal representative of the temperature of the oil within the sensor.
