Abstract: A method of interrogating a phase based transducer by providing a pulsed input including two different wavelengths. The different wavelength components can be used to derive a phase change experienced by a synthetic wavelength, and by arranging for the synthetic wavelength to be significantly greater that the component wavelengths, the phase so detected has a reduced sensitivity, and is less susceptible to overscaling effects.

Abstract: A control apparatus can electronically control the operation of a multi-cylinder engine in a precise manner. A first signal generator 1 and a second signal generator 2 are provided on a camshaft operatively connected with a crankshaft for generating a cylinder identifying signal SC and a reference position signal ST, respectively, in synchronism with the rotation of the camshaft. A pulse signal generator 6 or 12 is provided on a crankshaft for generating a pulse signal P of a high frequency in synchronism with the rotation of the crankshaft. The reference position signal ST contains a series of pulses each indicative of a first and a second reference position for each cylinder which are modified by counting the number of pulses in the pulse signal P to provide exact reference positions. A microcomputer 5 or 15 controls the engine based on the exact reference positions of each cylinder thus obtained. In a modified form, instead of two signal generators 1, 2, a single signal generator 11 is employed which is provided on the camshaft for generating a single signal SCT which contains a series of pulses having different pulse widths corresponding to different cylinders. The signal SCT and the pulse signal P are input via an AND gate 17 to a counter 16 where the number of pulses in the pulse signal P during the pulse width of each pulse of the SCT signal is counted for cylinder identification.

Abstract: For the purpose of knowing an angular position and a rotational speed of a rotary body, according to an encoding pattern on an encoder mounted to and synchronously rotated with the rotary body, rotational angular position signals consisting of n-phase rectangular waves and sensing pulses occurring at a predetermined rotational angle interval are generated. In response to the issue of each sensing pulse, levels of the respective rotational angular position signals are detected, a variation pattern of a combination of the detected n levels is compared with a reference variation pattern, and it is determined whether an abnormal condition has arisen or not, and if the condition is normal, whether the variation pattern is a forward traveling pattern or a backward traveling pattern. In the case of the forward traveling pattern, (+1) is added to a rotational angle counter, while in the case of the backward traveling pattern, (-1) is added to the rotational angle counter.

Abstract: A method for measuring a distance between connectors of different line cards is described. A first measurement component configured on a first line card sends a measurement signal to a second connector configured on a second line card using a first connector configured on a first line card, and determines a distance between the first connector and the second connector based on the measurement signal. The second connector receives the measurement signal and sends a response result of the measurement signal back to the first measurement component, to enable the first measurement component to determine the distance between the second connector and the first connector. The distance between the first connector and the second connector being determined based on the measurement signal enhances flexibility, universality, and accuracy.
