    摘要: An engine control system includes a speed sensor apparatus for providing signals to an engine control module (ECM) indicative of the speed and timing of an internal combustion engine. The apparatus includes a primary and a secondary Hall device affixed to one pole of a dipole magnet. Independent flexible circuits connect each of the Hall devices to an output connector adapted to receive a cable connected to the ECM. The magnet, primary and secondary sensors and primary and secondary flexible circuits are potted and encased within a sensor housing that is configured for sealed mounting to a housing surrounding the timing wheel of the engine. The outputs from the two sensors are independent of each other and are simultaneously provided to the ECM. The ECM includes means for providing the output from the primary sensor to engine control routines utilizing speed and timing information while the primary sensor is operational. Means are also provided that derive a phase difference value between the primary and secondary outputs. In the event that the primary sensor fails, the ECM modifies the secondary sensor output by the phase difference value and provides the modified output to the engine control routines. In this manner, the engine control routines are provided with a consistent and continuous speed and timing signal even when one sensor fails.

    摘要: A position sensor is disclosed having a transducer formed by a Hall-effect device and permanent magnet secured within a housing on either side of a low permeability gap. A target secured to an active member, such as an EGR valve plunger moves within the gap. The target has a flux modulating property that varies with position along a direction of travel. In one embodiment, the reluctance of the target varies with position. Variable reluctance is achieved in some embodiments by varying the cross section of the target with position. In some embodiments, a second target having substantially constant reluctance secures to the active member and moves within a gap defined by a second transducer. The output of the second transducer is used to normalize the output of the first transducer and compensate for anomalies such as drift and movement other than in the direction of travel of the active member.

    摘要: A process, system, and component configuration are described that discourages customer acceptance/use of will-fit, reconditioned, and counterfeit product components, by determining whether or not a serviceable product component is genuine. If a component is determined to not be genuine, then appropriate action may be taken to warn operators and document such findings. For example, one or more markers are disposed or otherwise put on the subject serviceable product component and serves as a targeted feature, and/or a particular characteristic of the filter itself is identified as the targeted feature. A sensor is used to detect the targeted feature and obtain information unique to the serviceable product component. The targeted feature(s) identifies the particular serviceable component as genuine and forms the basis for determining whether a genuine component has been installed. In some circumstances, a fluid filter product is the component that is the subject detection.

    摘要: A method and system for improving sensor accuracy of diesel emissions is disclosed. The method and system change the sensor reading as a function of sensor age to provide a more accurate measure of the diesel emissions. By estimating the degree of sensor error and then providing a gain correction factor as a function of sensor age, a more accurate measure of the diesel emissions is provided.

    摘要: A non-oriented direct coupled sensor for gear teeth or similarly shaped discontinuities of a ferrous magnetic or magnetic target uses a single magnet and a direct coupled Hall cell integrated circuit to detect the presence or absence of gear teeth. The sensor incorporates techniques for flux steering and flux reversals independent of the orientation of the sensor to the target to overcome the operate or release point of a Hall switch, latch or other device. The use of spaced apart, offset flux concentrators provides a sensitive device with favorable tolerances in temperature and air gap.
