Abstract: Electrolysis cell comprises, in one embodiment, a proton exchange membrane (PEM), an anode positioned along one face of the PEM, and a cathode positioned along the other face of the PEM. A multi-layer metal screen for defining a first fluid cavity is placed in contact with the outer face of the anode, and an electrically-conductive, compressible, spring-like, porous pad for defining a second fluid cavity is placed in contact with the outer face of the cathode. The porous pad comprises a mat of carbon fibers bound together with one or more, preferably thermoplastic, resins, the mat having a density of about 0.2-1.5 g/cm3. Cell frames are placed in peripheral contact with the metal screen and the compression pad for peripherally containing fluids present therewithin. Electrically-conductive separators are placed in contact with the metal screen and the compression pad for axially containing fluids present therewithin.

Abstract: An optical receiver is provided with inputs for receiving two fiber optic lines. The two fiber optic lines carry redundant data. An optical interface passes the respective signals therein to a comparison unit. The comparison unit compares the signals and determines which has the better quality and passes the better quality signal on to a processing interface. Clock data for operating the comparison unit is extracted from the optical signals.

Abstract: The present invention discloses a method for portioning foodstuffs in three dimensions. A step in portioning according to the present invention includes scanning the foodstuff to be portion. Followed by a step of generating a three-dimensional map of the foodstuff. Followed by a step of comparing the generated three-dimensional map of the foodstuff with the desired shape which is stored in the memory of a computer. The computer will then be able to determine the particular cutting path in three dimensions in order to arrive at the predetermined shape. Followed by a step of cutting in one direction to fix at least one dimension of the foodstuff. Followed by a step of determining whether the foodstuff is within the tolerance limits or whether the foodstuff portion has moved during the first cutting operation. If the foodstuff portion has moved, the foodstuff will be rescanned. Followed by a step of generating a two-dimensional image of the foodstuff.

Abstract: A wavelength conversion apparatus and method uses four wave mixing of a first wavelength and a control wavelength in an optical fiber to convert the first wavelength to a desired wavelength. Four wave mixing is produced by operating the optical fiber at a predetermined input power density and by using a fiber length which provides substantial Raman gain. The first wavelength is converted to a higher wavelength by using the higher wavelength four wave mixing signal and converted to a lower wavelength by using the lower wavelength four wave mixing signal.

Abstract: A chromatic dispersion measurement technique for optical components using baseband amplitude response of RF modulated optical signals and a dispersion reference in providing a measurement both of the magnitude of the dispersion and whether the dispersion is positive or negative.

Abstract: An improved compact disk player device is provided which has compact dimensions and results in reduced cost of manufacturing. The compact disk player device achieves the above described advantages by providing a unique construction whereby multiple compact disks can be loaded onto a retractable tray along parallel, spaced apart planes. In doing so, compact disks to be loaded onto the receiving tray are positioned so as to overlie one another. An angularly rotatable pick-up is provided which reads disk data from a selected one of the compact disks and which rides along a tilted guide which compensates for differences in height between respectively selected disks. The overlying disk construction results in a compact design which will ultimately reduce cost of manufacture. Clamping elements are also used to stabilize, control and protect a rotating disk during a read operation.

Abstract: Improved PMD performance is achieved in fiber optic cable fabricated in accordance with the principles of the invention by twisting each of a plurality of optical fibers in a controlled manner as the cable is being formed. A controlled amount of twist is imparted to each optical fiber uniformly along its entire length. Uniformity of twist reduces twist-induced strain and promotes optimum PMD reduction.
