    摘要： Methods, systems, and apparatus, including computer program products, for calculating or applying a gradient over a region in a multi-dimensional space. A boundary defines the shape of the region. A gradient specifies a value transition between a starting position and an ending position. The following actions are performed to calculate a gradient value at any point in the selected region: determining an interpolation vector extending from an effective origin included in the starting position through the point to the ending position and defining a gradient value for the point according to the gradient and based on the position of the point along the interpolation vector relative to the effective origin and an intersection point where the interpolation vector meets the boundary.

    摘要： A simple, reliable, compact and inexpensive automobile engine misfiring detection system includes a basic capacitive pressure transducer, attached to a bleeder pipeline equidistantly from each point where the exhaust manifold is attached to the engine, and made of two closely spaced insulating plates whose opposed faces contain conductive layers, and one of which plates is a flexible diaphragm of low mechanical hysteresis. The transducer is thus coupled to a variable exhaust gas pressure source which under normal operating conditions remains at a substantially constant pressure level. The output signal from the transducer has its high-frequency AC component attenuated by a low-pass filter, whose output in turn has its DC component substantially removed by capacitive blocking, after which the remaining AC output is then amplified by a circuit including an operational amplifier. This AC-amplified signal is then compared with a "reduced-magnitude average" reference signal (produced by an AC-to-DC conversion side-circuit followed by magnitude-level adjustment). The comparator output triggers a one-shot monostable multivibrator used to produce an on-off switching signal which operates an LED alarm signal notifying the driver of engine misfiring and also sends an electronic signal to the car's central processor.
