Abstract: A method and apparatus are disclosed for reducing flow induced vibration in at least one subsea structure. The method comprises the steps of, via at least one subsea acoustic sensor (190), detecting at least one characteristic associated with acoustic energy in sea water proximate to the sensor (190), responsive to the detected characteristic, varying at least one operational parameter of a fluid flowing along a fluid flow pathway associated with a pipe member (160).

Abstract: This disclosure is directed to wraps, including vinyl wraps, that can be placed around an industrial site including an oil and gas site and/or tank to camouflage the site. The wraps may contain landscape scenes or custom pictures that enable the industrial site, or the oil and gas site and\or tank, to blend in with the surrounding environment.

Abstract: An apparatus for dispensing an amount of fluid is disclosed where the amount of fluid and the pressure thereof is controlled by the height of the fluid relative to the spray mechanism that can dispense the fluid. A reservoir is positioned above the spray mechanism such that a column of fluid constitutes the reservoir of fluid. The height of the fluid reduces upon actuation of the spray mechanism. A controller detects the initial height of fluid and the height of the fluid after the dispensing operation to determine the amount of fluid dispensed. The controller is programmed with a parameter for the amount of fluid to be dispensed. If the determined amount of fluid dispensed is not within the parameters, the controller operates an iterative process to refill the reservoir to an amount such that during subsequent spraying operations, the amount dispensed approaches the parameter amount of fluid.

Abstract: Disclosed is control circuitry for providing controlling a motor responsive to feedback signals. The control circuit includes a velocity sensor for coupling with the motor for providing a velocity feedback signal responsive to the velocity of the motor, and circuitry for providing a feedback signal responsive to a voltage associated with the motor, such as the back emf of a coil associated with the motor. The control circuitry can be used enhance the Z-axis control of a tool of a work apparatus for performing work operations on a work material, such as a cutting apparatus for cutting a sheet of vinyl having a releasable backing for generating graphic products.

Abstract: An apparatus and method for printing graphic images by laser thermal transfer uses a laser source and a programmable pulse generator to transmit a pulsed infrared laser beam in accordance with a printing program of image data to print graphic images on sheet material. The pulsed laser beam is transmitted through a focusing lens, and the focused beam is in turn scanned by a scanning device through a laser window assembly into an ink web along a line of laser impingement. The ink web contains a layer of printing ink and overlies the sheet material supported on a roller platen. The laser window presses the ink web into the sheet material against the roller platen along the line of laser impingement to facilitate the transfer of ink from the web to the sheet in accordance with the printing program of image data.
