  • Patent number: 11717246
    Abstract: In a medical image generation method, projection data of a scanned object is acquired during rotation of a radiographic source, and a scout image of the scanned object is generated in one scanning direction using corresponding projection data in two opposite scanning directions in the projection data. The scanning direction is used to represent a relative position relationship between the radiographic source and the scanned object. Using projection data in two opposite directions to generate a scout image in one direction during rotary scanning of a radiographic source can significantly shorten the generation time of the scout image.

  • Patent number: 11137119
    Abstract: A tubular solid state lighting device has a pin safety circuit electrically connected to connection pins of the one end. The pin safety circuit comprises two protection components, of different types. In one set of examples, there is an electrically controlled isolation switch and an electronic switch which functions as a high voltage isolation barrier. The switch provides full galvanic contact separation, whereas the isolation barrier provides current protection if the isolation switch is not functional. In another set of examples, there is a mechanically controlled isolation switch and an electrical or electronic isolation barrier. This provides two levels of protection, but requiring only a single manual operation by the installer of the lighting device. It avoids end-of-life protection circuitry being triggered during the installation of the lighting device.
