Abstract:
TOF and color sensing detector structures have x-axis spaced-apart y-axis extending finger-shaped gate structures with adjacent source collection regions. X- dimension structures are smaller than y-dimension structure and govern performance, characterized by high x-axis electric fields and rapid charge movement, contrasted with lower y-axis electric fields and slower charge movement. Preferably a potential barrier is implanted between adjacent gates and a bias gate is formed intermediate a gate and associated source region. Resultant detector structures can be operated at the more extreme gate voltages that are desirable for high performance.
Abstract:
Bei einer Kraftstoffeinspritzdüse mit einem im brennraumseitigen Endbereich des Gehäuses (1) angeordneten Kühlkanal (6) wird eine, gute Kühlung der thermisch hoch beanspruchten Bereiche dadurch erreicht, dass der Kühlkanal (6) näher zur Düsennadelbohrung (2) als zur Außenseite des Gehäuses (1) angeordnet ist und eine Querschnittsfläche aufweist, deren Breite höchstens gleich der sich in Achsrichtung der Düse erstreckenden Höhe bemessen ist.

Abstract:
Effective differential dynamic range in a differential pixel detector is increased by avoiding saturation effects due to common mode contribution in optical energy to be detected. Photocurrent generated by each photodetector pair is directly integrated by an associated capacitor over an integration time T. Within time T, before either integrated capacitor voltage reaches Vsat for the photodetector, at least one of the capacitors is reset to a voltage such that the desired differential detector signal is still determinable. Reset may be generated externally or internally to the differential pixel detector.
Abstract:
The invention relates to an injection valve comprising a housing (2), a retaining nut (1) and a nozzle body (3), said retaining nut prestressing the nozzle body against the housing (2). The surface mating (9, 10) between the retaining nut (1) and the nozzle body (3) is optimized in such a way that an intense prestressing force is exerted on the nozzle body without damaging the retaining nut. At the same time, the prestressing force optimizes the support of the pressure chamber (5) in such a way that a nozzle body which is resistant to high-pressure is provided.
Abstract:
The invention relates to a fuel injection valve comprising a nozzle body (300) which has a central guiding bore hole (312) and a supply channel (338) located to the side of the guiding bore hole (312). Both the bore hole and the supply channel open into a pressure chamber (334). A parting wall (346) having a smallest possible wall thickness is situated between the bore hole and the supply channel. The nozzle body (300) has a shoulder on the front end thereof, whereby the supply channel (338) projects more steeply into the pressure chamber (334), resulting in an increased wall thickness. As a result, the nozzle body (300) exhibits a greater resistance to pressure.
Abstract:
In a simple manufacturing process, the piezoelectric actuator is inserted into a pre-fabricated hollow profile which is then sealed with a passivating layer. The hollow profile is configured in such a way that the contact pins, which are connected to the piezoelectric actuator by means of contact lugs, are arranged in a precisely defined position.
Abstract:
Rapid calibration of a TOF system uses a stationary target object and electrically introduces phase shift into the TOF system to emulate target object relocation. Relatively few parameters suffice to model a parameterized mathematical representation of the transfer function between measured phase and Z distance. The phase-vs-distance model is directly evaluated during actual run-time operation of the TOF system. Preferably modeling includes two components: electrical modeling of phase-vs-distance characteristics that depend upon electrical rather than geometric characteristics of the sensing system, and elliptical modeling that phase-vs- distance characteristics that depending upon geometric rather than electrical characteristics of the sensing system.
