Abstract: An apparatus and method for reducing lumen depreciation caused by other than lamp lumen depreciation. In one aspect, manufacturing and assembly of the fixture uses clean-room light techniques. In another aspect of the invention, materials that have a propensity to outgas are shielded from direct exposure to light energy. Other aspects of the invention include other methodologies to eliminate causes for lumen depreciation.
Abstract: A system for cooling includes a surface to be cooled and at least one film-cooling hole within the surface for allowing a film cooling jet of coolant to reach the surface, each of the at least one film-cooling hole having a diameter. The at least one film-cooling hole is shaped to preserve momentum of the coolant and assist in preventing entrainment of the hot gases. A method of cooling a surface proximate hot gas includes providing coolant through a w-shaped film-cooling hole to form a cool film between the hot gas and the surface and preserving momentum of the coolant using the w-shaped film-cooling hole to assist in preventing entrainment of the hot gases.

Abstract: The tub is mounted to a frame for alternative movement from a position wherein the tub is centrally located with respect to the longitudinal axis of the frame. The tub may be tilted from a position centrally located to a side dump position which is offset with respect to the longitudinal axis of the frame. The apparatus for moving the tub from its centrally located position to its side dump position is a barrel pivotally mounted to the tub and an extension rod which is pivotally mounted to the frame.
Abstract: The present invention provides an overhead support apparatus for assisting a user while performing rehabilitation physical activities and includes a track assembly supported by the ceiling and a suspension device that depends from the track assembly and is attached to the user so that the apparatus acts to prevent the user from falling down during physical activities. The suspension assembly includes a trolley adapted to traverse the track assembly, a locking snap assembly attached to the trolley and associated with a swivel, and an adjustable lanyard that is connected to the swivel at one end and to a body harness at its opposite end, which body harness has straps for encircling the torso and legs of a user.
Abstract: The present device enables measurement of the susceptibility of corn plants to root lodging. The device is used to push over a corn stalk and the force used to push over the stalk, and the vibration of the stalk caused by the push are recorded. As material breaks in the stalk, an accelerometer, measures stalk vibration response to the breaking events; the data is then recorded to allow quantitative measurements of the susceptibility of corn plants to root lodging. This allows meaningful comparisons of various hybrids at early stages of hybrid evaluation and advancement.

Abstract: The present invention relates to a new liner for repairing a damaged portion of a pipe. A lining tube formed from a non-resin absorbent material has an exterior surface adapted to receive a curable resin and contact an interior wall of the pipe. The present invention also includes a main/lateral liner assembly for repairing the junction between main and lateral pipes using a non-resin absorbent liner for at least a portion of the lining.
Abstract: A method, apparatus and system for illuminating a large area with plural high power lighting fixtures. The method includes identifying fixtures having a likelihood of affecting playability or glare or spill light relative to a point of view on or off the large area. The method includes steps to identify such fixtures for the purpose of adding a component which improves lighting or decreases glare or spill light for the point of view. A further method does so for multiple points of view relative to the large area, whether on or off the large area. One component is a long visor that would be added only to identify fixtures.
Abstract: The present invention provides for a methods, system, and apparatus relating to data transmission. One method of the present invention includes representing data using at least one ultra wideband pulse, sending the at least one ultra wideband pulse over an electrically conductive guided media, and recovering the data from the at least one ultra wideband pulse. The present invention can be used in conjunction with telephony applications, cable TV applications, power line applications, fiber optic applications, and data bus applications.

Abstract: Described herein is an improved tool and method for installing undermount drawer slides in a cabinet. The undermount drawer slides are of the type commonly used to conceal the drawer slide from a user for improved aesthetics. The tool is designed so that the drawer slide fits snugly and securely to the tool and the drawer slide may be adjusted horizontally or vertically without moving or becoming displaced easily. The method of using the tool provides a means for securely attaching the drawer slide within the cabinet without variation, thereby ensuring that drawers open and close smoothly and securely.
Abstract: A method, system and type of database for transmitting data is disclosed in which the data is organized into a structured linear database. The structured linear database includes a routing header portion, a file allocation table, a data portion and a tailbit portion. The structured linear database may be transmitted over any type of network, such as a TM-UWB system or a fiber-optic system. Once the data to be transmitted is identified, a corresponding field is identified in the field allocation table giving the location of the data within the transmission. This field is then referenced by the user to access the specific type of data desired at the given location of the transmission. this process may be repeated enabling data to be stored on transmission lines and accessed at any point at any time providing an always on network.

Abstract: A method of laying out a grid of points across an area comprises designating a starting reference point; projecting with the laser beam a first reference line intersecting the first reference point and extending in a first direction relative to the area; designating the set of first line reference points along the first reference line; projecting with a laser beam a second reference line from each of the set of first reference line points in a direction at least partially across the area; designating a set of second line reference points at or near the area along each of the second reference lines, so that a grid of points across the area correlated to at least one laser beam projection is created. In this manner, the laser provides a quick and accurate straight line for referencing points in the grid. The method could be used to just lay out a grid of lines.

Abstract: One aspect of the present invention is a non-electronic method of controlling the power provided to the lamp through use of multiple secondary taps off the secondary side of the HID ballast. This allows for a base capacitor to be used, along with the multiple secondary taps of the ballast, to vary the power to the lamp for purposes of providing constant light output, dimming capabilities, or to hold the power constant, or any combination of such.
Abstract: A liner tube is provided for repairing either a single pipe line or a main pipe line having a lateral pipe line connected thereto. The liner tube assembly includes a liner tube impregnated with a liquid material capable of curing and hardening. The liner tube includes a gasket or band positioned about the juncture of the pipe lines. The gasket or bands form a tight seal between the liner tube and the pipe line.
Abstract: An apparatus, method, and system for lighting target areas with bollard or pagoda style or type lights in a controlled and efficient manner. The apparatus includes a housing with a light source, optic system, and a control circuit. The light source and optic system are configured to produce a highly controlled output beam pattern and shield from normal viewing angles direct sight of the source. This enables control of glare and spill light which can improve effectiveness, efficiency, and energy usage.
