Title: Angular position sensor for an internal combustion engine fitted with an electronic ignition system
Inventor: MENARD CHRISTIAN
IPC: F02P5/15
Filed: 1979-09-27
Granted: 1982-10-14
Abstract: An internal combustion engine with M cylinders having an electronic ignition system, a pistons position sensor having a set of M+1 identical conductive members, which are synchronous with rotation of the engine's crankshaft. M of the conductive members are regularly spaced. Two fixed detectors adjacent the rotating members sense the members and supply identical electrical signals. The detectors are spaced to provide the signals out of phase by an amount that is substantially higher than the maximum ignition advance of the engine. Electronic circuits process the signals from the two detectors, include a first circuit that supplies a synchronization signal for the cycle igniting the engine, and a second circuit, which supplies two representative synchronization signals of the static advance and of the maximum dynamic advance during ignition.

Title: Circular raster sweep generator
Inventor: KING DON G
IPC: H04N3/16
Filed: 1981-06-16
Granted: 1984-12-13
Abstract: A sweep generator (10) for producing a circular raster (16) of curved scanning lines (18) on the target surface of a video camera is disclosed. Each curved trace follows a substantially circular path through a scanning angle of 360 The circular raster is generated by horizontal and vertical scanning signals (28, 30) which are synchronized with the horizontal line frequency of a video receiver. The horizontal scanning signal (28) is characterized by a constant amplitude component (28A) followed by a sine wave component (28B), and the vertical scanning signal (30) is characterized by a composite waveform including a constant amplitude component (30A) followed by a sine wave component (30B) which is shifted 90° in phase with respect to the sine wave of the horizontal scanning signal.The constant amplitude components of each composite waveform are synchronized with the horizontal blanking pulse (32) which occurs during horizontal retrace of the scanning beam in the receiver, and the phase shifted sine waves are synchronized with the forward trace of each horizontal line in the receiver. This produces a one-to-one correspondence of each circular trace in the video camera with each horizontal forward trace in the receiver. The composite scanning signals are amplitude modulated by a sawtooth signal (36, 38) which is synchronized with the receiver field frequency, thereby producing the circular raster of concentric scanning lines. According to a preferred embodiment, each composite waveform is produced by a read only memory (ROM) (40,42) which is synchronously cycled at the line frequency while driving a digital-to-analog converter (44, 46). The modulating signal is generated by a sawtooth oscillator (60) which is synchronized with the receiver field frequency.
