Title: Control system for ignition of fuel-air mixture in IC engine
Inventor: SCHWARZ SIEGFRIED
IPC: F02P5/15
Filed: 1996-10-23
Abstract: An ignition timing/control system for an IC engine employs a pre-ignition knock sensor in each cylinder to monitor the prevailing combustion characteristic and thereby set limits to permissible flame speed/peak pressures for storage by the electronic engine controller under all conditions of operation as identified by measurements of rpm, air induction, fuel injection, ignition timing, temperature etc.. The system is particularly effective when igniting a lean fuel/air mixture and achieves an efficient combustion performance by control of the intensity and duration of the igniter source which may be linear or rotary spark or high intensity laser.

Title: Pulse inverter with improved efficiency
IPC: H02M7/48
Filed: 1997-06-28
Abstract: A pulse inverter has several inverter blocks working with chokes (2) assigned to a current node.  The pulses from the individual blocks are displaced in time so that with equal amplitude of the current waveforms at the node, the efficiency of the inverter is improved by reducing the end stage clock frequency and so that a uniform distribution of current, and therefore power, results.  Each inverter block has its own controller, and one of these controllers handles all control tasks as a master control (11), with the other controllers acting as slaves to undertake the synchronous but time shifter pulse width modulation.
