    Abstract: A flexible voltage transient detector circuit is disclosed. The detector circuit includes an initialization unit, a first comparator, and a second comparator. The output of the initialization unit decides the operational modes of an integrated circuit. When the power voltage suddenly falls below the lower reference voltage, the first comparator will give an output to reset the initialization unit and force the integrated circuit into the initialized mode. Once the power voltage rises back above the higher reference voltage, the second comparator will order the counting of the initialization unit to start. The integrated circuit remains in the initialized mode until the counting stops after a period of delay time which can be flexibly set as needed and then returns the normal situation. This circuit design prevents the unpredictable operation of the integrated circuit.

    Abstract: A method of forming a capacitor for DRAM or other circuits is described which avoids the problem of weak spots or gaps forming between a polysilicon contact plug and the first capacitor plate. A layer of first dielectric is formed on a substrate, A layer of second dielectric is formed on the layer of first dielectric. A layer of third dielectric is formed on the layer of second dielectric. A first hole is formed in the first, second, and third dielectrics exposing a contact region of the substrate. The first hole is then filled with a protective material and a second hole is formed in the layer of third dielectric using the layer of second dielectric as an etch stop. The first hole lies within the periphery of the second hole. The protective material prevents re-deposition of the third dielectric. The remaining protective material is then removed and a layer of conducting material is formed on the top surface of the layer of third dielectric, the sidewalls of the second hole, the sidewalls of the first hole, and the contact region of the substrate thereby forming a first capacitor plate.

    Abstract: The present invention provides a system for detecting and removing resonance from crankshaft speed measurements comprising signal demodulation and deconvolution processing. According to the invention, a crankshaft speed sensor sends an appropriate signal corresponding to crankshaft speed to an engine controller. The input signal with resonance noise is subjected to a demodulation operation in N demodulation subsystems for resonance detection and identification. Also, the input signal with resonance noise is subjected to a deconvolution operation in N deconvolution subsystems for resonance noise removal. The demodulated signals are compared to a given set of criteria for selecting a desired signal subsystem. The desired demodulated signal subsystem is then used to screen the deconvolved signal so that only a matching deconvolved signal exits the system as the system output. Accordingly, the signal from a deconvolved signal subsystem matching the selected demodulated signal subsystem is selected as the system output. By properly identifying the desired signal subsystem during demodulation and suppressing resonance noise during deconvolution, the system output signal has an enhanced signal-to-noise ratio. Hence, the output signal is better suited for further processing, such as engine misfire detection, than according to the prior art.

    Abstract: The present invention provides a method of detecting internal combustion engine misfiring. The method includes mixed rate sampling of crankshaft angular velocity for a plurality of cylinder firing events to generate a crankshaft angular velocity signal and a cylinder firing synchronization signal. The apparatus for executing the method comprises a crankshaft in operative relation with the internal combustion engine. A crankshaft sensor wheel is rotatably triggered by the crankshaft and includes a plurality of predetermined sensor indicators disposed at least at two different angular widths. A sensor is positioned adjacent to the wheel for sensing the passage of each indicator in producing a signal pulse having a duration corresponding to the angular width of the sensed indicator in response thereto. A counter determines the time intervals between signal pulses generated by the sensor including a synchronization signal time interval and an RPM signal time interval. The synchronization signal time interval is then utilized to calculate a plurality of crankshaft angular velocities for a plurality of RPM indicators replaced by a synchronization indicator. A misfire detector then determines if a misfire has occurred by interpreting a series of data points developed from the plurality of crankshaft angular velocities.
