Title: Schaltung zur Erzeugung eines Ausgangssignals in Abhängigkeit von zwei Eingangssignalen
Inventor: JOHNSON BRET
IPC: G11C7/22
Filed: 1998-09-30
Abstract: Durch eine Schaltung (SG) zur Erzeugung eines Ausgangssignals (output clock) in Abhängigkeit von zwei Eingangssignalen (clock, data valid) wird eine Ausgangstreiberschaltung eines getakteten integrierten Halbleiterspeichers vom Typ DRAM angesteuert. Durch die Ansteuerung mit Hilfe eines Gültigkeitssignals (data valid) wird sichergestellt, daß die auszugebenden Daten im gültigen Zustand sind, bevor der Ausgangstreiber freigeschalten wird. Dadurch wird verhindert, daß beim Speicherzugriff unterschiedliche Laufzeiten von Eingangssignalen der Ausgangstreiberschaltung zu mehrfachen Schaltvorgängen des Ausgangstreibers innerhalb eines Zugriffszyklus führen. Durch eine ereignisorientierte Steuerung der Freigabe des Ausgangstreibers wird die Funktionalität auch bei variablen Frequenzen der Taktsteuerung (clock) gewährleistet.

Title: Fuel injection system for internal combustion engine
Inventor: HOSOKAWA KOUJI
IPC: F02D41/34
Filed: 1998-12-01
Abstract: The fuel injection system has a control which generates reference pulses of set width to which the fuel injection pulses and the air inlet pulses are matched. The computed fuel injection pulses are retarded and the air input pulses are enhanced to match the two for an optimum burn with maximum efficiency.  The required fuel/air ratio and the amounts of fuel/air are determined by the dynamics of the engine and the control settings. Monitors measure the air flow into the engine and the length and volume of the fuel pulses.

Filed: 1999-07-15
Abstract: Flooding apparatus for dental sample comprises a controlled flooding channel (6). Apparatus to flood dental samples (1), with a controlled fluid, has a flooding channel (6) over the samples with a defined width, height and length. The samples are subjected to a laminar flow at a defined flow volume and speed.

Patent DE-19941635-A1 (DE)
Inventor: MUELLER REINHARD
IPC: G08G3/02
Filed: 1999-09-01
Abstract: The invention relates to a method for the self-organising resolution of traffic conflicts between mobile objects on the surface of water. Using electronic locating receivers and communications receivers installed on board the objects and transponders that are operated in the broadcasting procedure, special onboard computers evaluate the object data that are received in terms of potential traffic conflicts. In the event that a conflict is identified, the status of the onboard computers of the relevant vehicles is temporarily divided in order to establish and organise a resolution to the conflict. The movements of the vehicles are co-ordinated within a master-slave structure of the onboard computers involved by transmitting way-point lists with the co-ordinates for the non-conflicting routes. The master-slave structure of the onboard computers is dissolved when the conflict characteristics are eliminated.
