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： An optical scanning device for scanning a document to produce image signals related to the density of the image on successively scanned document areas includes a platen for supporting a document and a surface of substantially uniform reflectivity extending along the edge of the platen. A bar of light is directed such that it strikes the document and the surface of substantially uniform reflectivity and moves across the document in synchronization with optical scanning of the document. Light reflected from the surface of substantially uniform reflectivity is directed to a plurality of reference transducers which sense the position of the bar of light. A servo control loop, responsive to the reference transducers, positions a reflector during the scanning operation such that the area on the document being scanned is properly illuminated.

摘要： In one embodiment, a system for determining maximum available engine output torque includes an engine speed sensor and a control computer produce a fueling command for fueling an internal combustion engine. The computer is configured to produce a maximum available engine output torque value as a function of the engine speed signal and the fueling command. In an alternate embodiment, the system includes a control computer configured to produce the maximum available engine output torque value as a function of engine speed, at least one engine intake parameter associated an intake manifold coupled to the engine, and an engine exhaust parameter associated with an exhaust gas structure coupled to the engine. In either case, an application control strategy is responsive to the maximum available engine torque value to control an engine-driven accessory as a function thereof.

摘要： An optical scanner for scanning an image on a document to produce an electrical signal representing the image density of the image at successively scanned points positioned along a scan line on the document includes a platen for supporting the document in a scan plane. A rotatable mirror in the scanner optical system is rotated at a non-uniform angular velocity to scan the document at a controlled scan rate which may be selected as a uniform scan rate. Rotation of the mirror is controlled by means of a servo control loop responsive to a reference signal and to the output of a reference transducer which receives light from a reference grating as the mirror is rotated.
