| 4617905 | Electronic ignition system for an internal combustion engine A mechanically timed ignition system for an internal combustion engine has a variable reluctance transducer mechanically operated by the engine to produce an output waveform having zero crossings coinciding with the desired instants of sparks. A comparato... | 10/21/1986 |
| 4356808 | Low-speed compensated ignition system for an internal combustion engine A switching transistor (7, 9) is serially connected with the primary (5) of an ignition coil; current flow therethrough is controlled from an a-c signal generator (16) with respect to an ON threshold level (Ue) to store electromagnetic energy, and an OFF ... | 11/02/1982 |
| 4301778 | Electronic ignition device An electronic ignition device for use with an internal combustion engine is coupled between an ignition coil switch and a magnetic pick-up. The pick-up produces a cyclical signal A which is integrated and applied to a first comparator, the other input of ... | 11/24/1981 |
| 4153850 | Circuit for producing a series of substantially square wave output signals A source of alternating current signals is applied across the inverting and non-inverting input terminals of a voltage comparator circuit through a series bias resistor. Electrical circuitry including a supply potential source and the comparator circuit o... | 05/08/1979 |
| 4095179 | Locating system to determine the position of movable bodies with respect to a reference The movable body is supplied with at least two marker elements to move therewith, the reference being at a fixed location at which a stationary transducer is located responsive to the marker elements and to provide output signals staggered in time as the ... | 06/13/1978 |
| 3938490 | Internal combustion engine ignition system for generating a constant ignition coil control signal An ignition system for use with an ignition coil and a source of alternating distributor pickup signals within an internal combustion engine. The system includes a zero crossing detector responsive to the distributor pickup signals and operative to genera... | 02/17/1976 |
| 3937193 | Electronic ignition system An electronic ignition system for a spark-ignition internal combustion engine. The ignition system is of the inductive type and includes an ignition coil having at least a primary winding and a switching device connected in series with it to control its c... | 02/10/1976 |
| 3933141 | Zero crossing circuit for electronic ignition system A temperature controlled ignition circuit includes a high voltage coil, ignition circuitry connected thereto and a magnetic generator for controlling the operation of the ignition circuitry and the production of a high voltage at the coil. A transistor in... | 01/20/1976 |
