    Abstract: A fastening assembly, used for fixedly fastening a first and a second structure (1100, 1200) of a device together, comprises an anchoring block (1500), an insert plate (1400), and a screw (1300). The first structure is provided with a hole (1110). The anchoring block, fixedly arranged on the second structure, includes two parallel holding flanges (1510, 1512) and two parallel protruding ribs (1520), wherein the holding flange (1510) further includes a slot (15101). The protruding ribs extend approximately perpendicular to the two holding flanges on two sides thereof. The insert plate is held between the holding flanges, and is provided with a threaded hole (1410) and a pair of hooked clamping members (1420) that respectively tightly clamp the protruding ribs. The screw extends through the hole of the first structure and engages in the threaded hole of the insert plate to fixedly fasten the first and second structures of the device together.

    Abstract: The present invention provides a method and system for detecting engine misfire with an optimal compensation of the RPM signal in an internal combustion engine in which the data signal containing a plurality of groups of sample data points is generated. Each of the groups of sample data points represents a cylinder firing event. The data signal is then conditioned for misfire detection processing. The data engine cycle compensation vectors for the RPM zone is then multiplied to the sample data of the RPM. Each group of sample data points is processed using signal processing techniques and then mapped into a single mapped data point. The mapped data points are further processed and then compared to a misfire detection dynamic threshold. A misfire detection signal is then output if any of the mapped data points fall outside the dynamic threshold. The misfire detection system achieves high degree of accuracy through a signal processing and statistical detection technology. The on-line RPM signal compensation reduces the effects to misfire detection caused by the RPM error from various sources and it further enhances the detection performance.

    Abstract: A process of opening, a stack of large diameter via holes, in a multiple levels of insulator layers, to be used for access of a laser repair procedure, applied to underlying integrated circuit shapes, while simultaneously opening small diameter via holes, in the same multiple levels of insulator layers, to be used to accommodate metal plug structures, has been developed. The process features the use of a polysilicon stop layer, used at the bottom of the stack of large diameter via holes, protecting underlying components of the underlying integrated circuit, from the dry and wet etching procedures used for the creation of the stack of large diameter via holes. The process also features the formation of metal spacers, on the sides of the large diameter via holes, created simultaneously during the formation of metal plug structures, and used again to protect the multiple levels of insulator layer, that would have been exposed, if left unprotected, during a wet etching procedure.

    Abstract: A method and system for detecting engine misfire in an internal combustion engine. A data signal containing a plurality of groups of data points generated from sampling crankshaft rotational displacement over three pre-determined angular sampling windows; is generated. Each of the plurality of groups of sampled data points represents a cylinder firing event. The data signal is conditioned, and the plurality of groups of sampled data points are, mapped into single misfire data points. The mapped single misfire detection points are then compared to a misfire detection dynamic threshold, and a misfire detection signal is output if the misfire detection points fall outside the dynamic threshold. The misfire detection system achieves high degree of accuracy through a multi-stage signal conditioning, multi-rate signal processing and statistical decision technology and a mixed size of window sampling strategy, and is capable of being installed on a large scale in motor vehicles through use of existing on board automotive microcontroller technology.

    Abstract: An engine system and method for variable valve lift (VVL) diagnostic techniques are provided. In one exemplary implementation, the techniques include receiving, at a controller, a camshaft position signal indicative of detected edges of teeth of a camshaft toothed member that is coupled to a camshaft of an engine. The camshaft is configured to actuate a VVL system, which is configured to control a lift of a valve of the engine. The techniques also include calculating, at the controller, a camshaft speed signal indicative of a rotational speed of the camshaft based on the camshaft position signal. A valve stuck index (VSI) value is then calculated, at the controller, based on the camshaft speed signal. The techniques also include determining, at the controller, whether the valve is stuck based on a comparison of the VSI value to a predetermined threshold.
