Title: Ignition system for a spark-ignition internal combustion engine
Inventor: VONDERAU JOSEF
IPC: F02P11/02
Filed: 1987-04-03
Abstract: The ignition system for a spark-ignition internal combustion engine comprises a high-voltage ignition arrangement (31) which is triggered by a trigger pulse transmitter (43) with trigger pulses in accordance with the position of the pistons of the internal combustion engine. A trigger-pulse control circuit (47, 49) which responds to the speed of revolution of the internal combustion engine suppresses the trigger pulses at speeds of revolution greater than a first predetermined limit speed of revolution and feeds the trigger pulses to the high-voltage ignition arrangement (31) in a delayed fashion at speeds of revolution in a range between the first limit speed of revolution and a second smaller limit speed of revolution. By retarding the ignition time, the power of the internal combustion engine is reduced as it approaches the first limit speed of revolution, as a result of which speed-of-revolution limitation with true running of the internal combustion engine is obtained. The trigger-pulse control circuit expediently comprises a timing element (49) which is to be started as a function of the control of the crankshaft and suppresses any trigger pulses by means of an inhibiting circuit (47) for the duration of its operating time. The high-voltage ignition arrangement (31) can be triggered in this case by leading edges of the ignition pulses, the overlap in terms of timing of the trigger pulses and the operating time of the timing element (49) delaying the leading edges of the trigger pulses. <IMAGE>

Inventor: CASTLEBERRY DONALD EARL
IPC: G09G3/20
Filed: 1988-05-27
Abstract: In a thin film transistor matrix addressed liquid crystal display, a constant RMS voltage on the data lines is assured. This eliminates uncertainty in the voltage levels on a pixel element caused by parasitic capacitance effects between the data lines and the pixel electrodes. The present invention is applicable to both binary level and gray scale level devices. In a period of time (T1 or T3) between the beginnings of successive scan line enabling signals (line n), a desired data voltage level is impressed on the data lines (line m) during a first portion of that time period, and then during a second portion of that time period a corrective voltage level is applied to the data lines such that an approximately constant RMS voltage is applied to the data lines. Alternatively successive desired data voltage levels may be applied to the data lines over an extended period of time and a corrective voltage level is applied in a subsequent period to maintain the overall RMS voltage approximately constant. <IMAGE>
