  • Patent number: 11953312
    Abstract: The invention includes a system and method for obtaining high-resolution 3D images of objects. The system includes three cameras and three light sources that have different wavelengths (e.g. a red light source, a blue light source and a green light source). Each camera simultaneously captures a color image of the object. A processor separates each of the red light images, the blue light images and the green light images into separate monochrome images using each of the red light source, blue light source and green light source. The quality of the images are not subject to limited resolution of conventional RBG images. Because three different wavelengths of light are used, the surface can be accurately imaged, regardless of its characteristics (e.g. reflectivity and transparency). The system is well suited for industrial uses that require a high volume of objects, particularly those of mixed material, to be rapidly inspected for defects as small as a few microns.

  • Publication number: 20090204562
    Abstract: The present invention provides a configurable multi-lingual advisory system (100). The advisory system include a database (110) a rule builder (120) and a rule analyzer (130). The rule builder (120) operationally receives and processes pre-defined inputs (160) for storing in the database (110). Upon receiving attribute value inputs (170), the rule analyzer (130) processes the attribute value inputs (170) based on the pre-defined input (160) and outputs an advisory report (150) according to an expert domain.

  • Patent number: 6921222
    Abstract: A high-speed printer is provided. The printer includes a media assembly for supporting a media roll that supplies the sheet of media and also for controlling a flow rate of the sheet of media through the printer. The sheet of media is received by the feedback control system, which is used to detect a slack position of the sheet of media. The slack position is used by the media assembly to determine a flow rate of the sheet of media through the printer. In addition, the printer also includes a roller system for receiving the sheet of material from the feedback control system and to feed the sheet of media to a print carriage.
