Abstract: Machine elements having Release Coatings that are Electromagnetic Wave Energy Cured, Highly Abrasion Resistant, Flexible, Low Friction, Release Coatings for Compliant Elastomeric Substrates used on Bowed Rolls and Press Rolls. 100% solids, highly abrasion resistant release coatings  which are polymerization cured with electromagnetic wave energy in  the wave length range of 5500 .ANG. to.006 .ANG.. These coatings will bond securely to commonly used structural and elastomeric,  rigid  and flexible, substrates; including metallic and non-metallic materials.  The coatings are compositions of varying percentages of  2-Phenoxyethyl Acrylate, Tetraethylene Glycol Diacrylate, Isobutyl Benzoin Ether, 1,6 Hexanediol Diacrylate,  Cycloaliphatic Bis A Epoxide, Polyurethane Acrylate, Methyl Methacrylate, Polysiloxane and other Acrylics, Tertiary Amines, Epoxidized Novolac, Fluorinated Alkyloxylate, Electromagnetic Wave Energy sensitive Photoinitiators, and Electromagnetic  energy  absorbers.          Multiple coating layers and multiple frequencies of  wave  energy are employed to cure the coatings in order to achieve optimum adhesion to substrates combined with optimum release, flexibility hardness, low friction, and abrasion  resistance  of coatings.          The useable electromagnetic wave lengths range from long wave ultraviolet down to short wave gamma rays (i.e.  5500  .ANG. to .006 .ANG.).

Patent CA-2200111-A1 (CA)
Title: Mechanical/electrical displacement transducer
Inventor: JACOBSEN STEPHEN C
IPC: G08C21/00
Filed: 1990-10-03
Abstract: Displacement measuring apparatus for measuring the displacement and movement of an object includes a sensor having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the area of the operative surface covered by an electrical/magnetic field producing member.  The apparatus also includes an elongate, flexible band capable of producing an electric/magnetic field, where the band is attached at one end to the sensor to roll over and cover or unroll from over and uncover the operative surface as the object whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is thus dependent upon the area of the operative surface covered by the band and thus by the position and movement of the object.

Abstract: In all-pixel reading image sensor or a noninterlaced output image sensor, an interlaced signal can selectively be output without the use of a frame memory or the like as an external circuit.         For outputting an interlaced signal from a three-layer three-phase drive all-pixel reading CCD image sensor, vertical shift registers 2 are supplied with first through third vertical transfer pulses to transfer signal charges in the pixels of an nth line, for example, to a horizontal shift register 4, and then the horizontal shift register 4 is supplied with horizontal transfer pulses to transfer (shift) the  signal charges of the nth line stored in the horizontal shift register 4 by two pixels, for example, to an output unit.  Thereafter, the vertical shift registers 2 are supplied with first through third vertical transfer pulses to transfer signal charges in the pixels of an (n + 1)th line to the horizontal shift register 4, in which the signal charges of the nth line and the signal charges of the (n +1)th line are mixed with each other.

Filed: 1997-11-05
Abstract: A loss-less optical cross-connect advantageously employs a plurality of optical rare earth-doped fiber optical amplifiers as gain-switched optical connections, for example, gain-switched optical distributors and gain-switched optical selectors. Each of the optical rare earth-doped fiber optical amplifiers acts as an ON/OFF switch. Also, both the gain-switched optical distributors and selectors employed in the optical cross-connect arrangement of this invention are a natural fit into today's optically amplified optical communication systems. In one embodiment, this is realized by employing a pump select circuit in conjunction with a plurality of pumps and the plurality of corresponding rare earth-doped fiber optical amplifiers. The particular pump and corresponding optical amplifier are selected by use of a control circuit arrangement to determine which output port or ports is (are) connected to the input port. The rare earth-doped fiber optical amplifiers and the corresponding pumps are employed advantageously for both the gain-switched optical distributors and the gain-switched optical selectors. In another embodiment, a so-called tuned pump arrangement is employed in conjunction with aplurality of filters and a corresponding plurality of rare earth-doped fiber optical amplifiers. A pump tuning arrangement is employed to control the tunable pump in order to select the appropriate one of a plurality of optical amplifiers to be activated, thus routing the input signals at any of a plurality of given wavelengths to the corresponding output line (or lines if broadcasting capability is employed). Again, the rare earth-doped fiber optical amplifiers and the corresponding pumps are employed advantageously for both the gain-switched optical distributors and the gain-switched optical selectors.
