  • MULTI-SPECTRAL IMAGING SYSTEM AND METHOD OF SURFACE INSPECTION THEREWITH
    Publication number: 20120242826
    Abstract: A multi-spectral imaging system includes a first light source that emits a first wavelength and a second light source that emits a second wavelength different than the first wavelength. The system further includes a camera having a lens, a beam splitter downstream of the lens and a pair of sensors downstream of the beam splitter. The lens is configured to focus the first and second wavelengths onto separate ones of the sensors, and the beam splitter allows one of the first wavelength or the second wavelength to pass through the beam splitter, and the other of the first wavelength or the second wavelength to be reflected off the beam splitter. One of the pair of sensors is configured to receive the first wavelength to produce a first image and the other of the sensors is configured to receive the second wavelength to produce a second image different from the first image.

  • MIXED SIZE DATA PROCESSING OPERATION
    Publication number: 20120233444
    Abstract: A data processing system 2 includes a processor core 4 and a memory 6. The processor core 4 includes processing circuitry 12, 14, 16, 18, 26 controlled by control signals generated by decoder circuitry 24 which decodes program instructions. The program instructions include mixed operand size instructions (either load/store instructions or arithmetic instructions) which have a first input operand of a first operand size and a second input operand of a second input operand size where the second operand size is smaller than the first operand size. The processing performed first converts the second operand so as to have the first operand size. The processing then generates a third operand using as inputs the first operand of the first operand size and the second operand now converted to have the first operand size.

    Abstract: A conveyor chain comprising rigid segments which extend over a width of the chain and are configured at least in part as plates of a uniform thickness and density. The segments are connected together in a loop and have elements to couple each segment to a following segment and a preceding segment. Neighboring segments may flex against each other from a substantially straight line to a convex angle in relation to the loop, so that the chain is adapted to conform to rollers or sprockets, but is resistant to flexing in the opposite direction. The segments overlap each other to form a transport area of substantially uniform thickness and density to provide at least one substantially gapless band of substantially uniform transmissivity to radiation in the transport area, wherein the connector elements are located outside the transport area. A system comprising the chain is also provided.

  • PRODUCTION OF 2-KETO-L-GULONIC ACID
    Publication number: 20120058563
    Abstract: The present invention relates to the production of recombinant microorganisms, in particular of the genus Gluconobacter, for production of 2-keto-L-gulonic acid (2-KGA) and/or L-ascorbic acid (hereinafter also referred to as Vitamin C), wherein the microorganism has been modified to overexpress L-sorbose dehydrogenase (SDH). This overexpression has been achieved by introducing of one or more copies of a polynucleotide encoding SDH into the genome of the host microorganism resulting in enhanced yield, production, and/or efficiency of 2-KGA production and/or Vitamin C compared to a non-modified microorganism. Expression of said one or more extra-copies of sdh is dependent on the integration site. The invention also relates to genetically engineered microorganisms and their use for the production of 2-KGA and/or Vitamin C.
