Abstract: A method for determining whether a variable valve actuation (VVA) device or subsystem is operating in an improper mode of operation is performed in real-time by an embedded engine or powertrain controller configured to monitor and evaluate an already-available knock sensor output signal. The knock sensor output is captured during a predefined sampling window, defined to include a valve closing event when the VVA device is operating in a proper mode. The captured knock sensor output signal is processed to detect the presence (or absence) of a valve closing event. The absence of a valve closing event when one is expected is indicative of a malfunctioning VVA device.

Abstract: A method for diagnosing an operational state of a variable valve lift (VVL) device in an engine, wherein the VVL device is capable of operating in two modes of operation. The method includes measuring a rotational speed of an engine crankshaft while the engine is running or cranking, correlating the measured crankshaft speed with an estimated engine cylinder pressure or torque, comparing the estimated engine cylinder pressure or torque with an expected range of engine cylinder pressure or torque values for the two modes of operation for the VVL device, determining if the estimated engine cylinder pressure or torque falls within the expected range of engine cylinder pressure or torque values, and activating an alert if the estimated engine cylinder pressure or torque falls outside the expected range of engine cylinder pressure or torque values to provide notification that the VVL device is operating in an improper mode of operation.

Abstract: An arrangement for smoothing a coherent laser beam of a limited yet substantial coherence length due to the presence of several discrete optical frequencies therein is operative for subdividing the coherent laser beam into a plurality of partial beams of substantially the same intensity. Each of the partial beams is then conducted in a different path, the length of at least one of which differs from that of another path by a distance amounting to a fraction of the coherence length. At least some of the partial beams are subsequently combined into a coherent output beam in which the partial beam issued from the one path is shifted by the distance relative to that issued from the other path.

Abstract: A method for operating an oil control valve in an internal combustion engine is provided. The oil control valve controls a camshaft phaser disposed at an output side of the control valve and includes a spool disposed in a spool housing. The camshaft phaser controls the phase relationship between a crankshaft of the internal combustion engine and a camshaft of the internal combustion engine. The method includes positioning the spool within the spool housing to substantially block oil flow between the camshaft phaser and the internal combustion engine when the engine is temporarily not running.

Abstract: A multi-port optical coupler applies the transition loss principle to exchange light among optical fibers through optical fiber bends. In a four-port embodiment, the coupler includes first and second injector fibers located in precise optical alignment on a substrate. A continuous fiber segment is configured so that a portion thereof is positioned on the substrate between and in optical alignment with the injector fibers. This portion of the fiber segment can be moved to a second position out of alignment with the injector fibers. First and second depressors impart first and second bends to portions of the fiber segment adjacent to and in optical alignment with the first and second injector fibers. Light can be injected into or extracted from the fiber segment through these bends by the injector fibers when the fiber bend is severe enough to create a transition loss and when the bends are in optical alignment with the injector fibers. The depressors can be adjustable to allow independent adjustment of the first and second bends and, therefore, the respective transition loss. When the bends are moved out of alignment with the injector fibers or are relaxed so that the transition loss is extinguished, the coupler is in effect turned off.

Abstract: An optical fiber is bent to form a discontinuous curve through which light can be injected into the fiber or extracted from the fiber. The bend can be formed by securing a portion of the optical fiber in a fixture and laterally displacing a portion of the fiber outside the fixture using a depressor. The depressor can be an integral part of the securing fixture or a separate device. The securing fixture can be adjustable so that the degree and location of the bend can be varied. Injected light can be sourced from a second optical fiber, and extracted light can be supplied to a second optical fiber which can have a lens at its free end.
