摘要:
An overhead LED light fixture including a base member with a vertical sleeve secured to the top of the base member for alignment with a pass-through opening. The fixture has a driver-tray assembly with a bottom member engageable with the base member at the pass-through opening, a vertical driver-support structure extending upwardly therefrom, at least one driver secured to the support structure, and the driver-tray assembly is slideably received within the vertical sleeve. When used as a canopy light, the driver-tray assembly is removable from below the canopy to facilitate servicing, upgrading or replacing of components.

The inventive LED-illuminated sign structure includes a frame, an outer shell and a plurality of separate LED emitters. The frame includes two opposite main support panels each having an upright outward surface, and shell-supporting members. The outer shell has a pair of opposite translucent sidewalls each extending along and is spaced from the respective outward surface. The LED emitters are spaced on each outward surface such that the translucent sidewalls are illuminated substantially entirely. The frame defines an open region for passing reflected light within the frame structure to and through the opposite translucent sidewall. The LED illuminator includes an LED emitter on a mounting surface, a one-piece lens member over the LED emitter and including a lens portion and a flange portion, and a gasket between the flange portion and the mounting surface. The lens member has a restraining ridge positioned to press the LED-emitter wires and the gasket against the mounting surface such that the wire portions between the ridge and the LED emitter remain in substantially fixed position regardless of wire movement beyond the restraining ridge.

An air cooled double ended high pressure sodium lamp fixture for growing plants in confined indoor spaces. The fixture seals the lamp and heat generated by the same to a reflector interior. Flow disruptors create turbulence in a cooling chamber thereby enhancing thermal transfer into a cooling air stream that flows over and around the reflector's exterior side thereby convectively cooling the lamp using the reflector as a heat sink. The lamp is effectively maintained at operational temperatures and the fixture housing is insulated from the hotter reflector by a gap of moving cooling air, allowing use of the double ended HPS lamp in confined indoor growing spaces.

The present disclosure provides a divider for packaging applications. The divider can separate products in the package into a plurality of groups, and can also contain relevant information about the products, as is required in the case of packaging tampons. The present disclosure also provides a method of packaging a plurality of products, using the divider.

A vehicle suspension system having radius arms that are connected to axle brackets through vertically arranged bushings. A third link of the suspension system is a track bar that connects one end of the axle to a laterally spaced point on the frame of the vehicle. The radius arms are sheet metal fabricated members that are assembled in a clam shell arrangement.

A method of processing magnetic field measurements to obtain magnetic dipole density image data is provided. The process involves making measurements of total magnetic field at a plurality of locations over an area of interest, dividing the area of interest into a plurality of narrow parallel strips, performing a strip integral and forming and solving a system of linear equations to obtain a generalized projection. The process is then repeated to produce a plurality of generalized projections from the original measured data by performing strip integrals for a plurality of different orientations of the strips. The process is then completed by performing an inverse Radon transformation on the generalized projections to obtain the magnetic dipole moment density image data.

Total wrist prosthesis comprising a radial component with a stem for fixation into the radius, a carpal component with one or more stems for fixation into the capitate and an intermediate bearing component which articulates with the radial component and allows rotational movement of the carpal component relative to the radial component plus hinged movement in two transverse planes. The radial component body may have a concave or convex surface to articulate with a matching surface on the intermediate bearing component. The carpal body may have a projection which is received in a recess in a base surface of the intermediate bearing component, and which has a pair of lugs that are received in an annular groove in the recess for an axially secure connection that allows small relative rotational movement as permitted by tendons and ligaments of the wrist.
