  • Publication number: 20240088890
    Abstract: A method of driving a transistor between switching states includes controlling a transition of a gate voltage at a gate terminal of a transistor during each of a plurality of turn-off switching events to turn off the transistor, wherein the transistor is configured to be turned off according to a desaturation time during each of the plurality of turn-off switching events; measuring a transistor parameter indicative of a voltage slew rate of the transistor for a first turn-off switching event during which the transistor is transitioned from an on state to an off state; and regulating a duration of the desaturation time for a next turn-off switching event based on the measured transistor parameter.

  • Patent number: 7693344
    Abstract: A method and a device for image processing and for a night vision system for motor vehicles, in which a standard camera that is sensitive in the near infrared delivers images which are displayed on a display arrangement having a lower resolution than the camera. In addition, the image processing method improves the raw images of the sensor using image-sharpening methods and/or contrast-enhancing methods, so that display on a display arrangement is made possible for viewing by a viewer.
