  • Patent number: 7151620
    Abstract: A lid for an imaging device is disclosed. The lid comprises a cover having a first side and a second side. The first side of the cover is adapted to retain an object to be imaged proximate to an imaging plate of the imaging device. At least one storage compartment is disposed on the second side of the cover.

  • Patent number: 6960753
    Abstract: Information is encoded, within a photosensor array, into photosensors which are not used for imaging. Some information encoding photosensors are permitted to receive unimpeded light, and for other photosensors the light is at least partially blocked or filtered. Alternatively, some photosensors may be disabled. When the photosensors are exposed to light, the resulting photosensor signals provide information. Alternatively, some photosensors may accumulate charge in the absence of light, and the resulting photosensor signals in the absence of light provide information. The information can be binary, or multiple-bit per pixel. Information can also be encoded into each individual color channel. Identification of vendor, part type, or other information can be encoded.

  • Publication number: 20030076550
    Abstract: A lid for an imaging device is disclosed. The lid comprises a cover and a reflector having a first side and a second side. The first side of the reflector is adapted to retain a first object to be imaged by the imaging device proximate to an imaging plate. The second side of the reflector is coupled to the cover, the cover being adapted to display at least a portion of a second object disposed between the cover and the reflector.

  • Publication number: 20030076547
    Abstract: A method for scanning an object, for example a document, by an image scanner is disclosed. The method comprises performing an initial scan of the object by displacing a carriage carrying a light source and at least one photosensitive device from a home position to an end position and performing a final scan by then displacing the carriage from the end position to the home position.
