Abstract: An example electrical contact includes a primary contact portion configured to contact a mating electrical contact to form an electrical connection: and two or more protrusions extending from a forward portion of the electrical contact that is forward of the primary contact portion along a longitudinal disconnect direction, wherein the two or more protrusions are configured to receive external arcing from the mating electrical contact during a disconnect event.

Abstract: Cleaning implement apparatus for cleaning boreholes formed within various different substrates, such as, for example, concrete slabs, concrete blocks, bricks, or the like, comprises a first embodiment for use within a power-operated tool, such as for example, a roto-hammer type power tool for drilling boreholes within concrete or brick substrates, while a second embodiment of the apparatus comprises a manually-operated tool. The first embodiment comprises a bit member having a slotted drive shank (SDS) connection for mounting within the chuck mechanism of the roto-hammer type power tool. In this manner, the same roto-hammer type power tool can be used for both drilling the borehole within the substrate as well as for cleaning the borehole by exchanging the cleaning implement for the drill bit.

Abstract: A sternal closure device is provided, comprising a first plate having a bone fixation region with at least one countersunk aperture for receiving a fastening means for affixing the first plate to one side of the sternum, and a locking region with at least one protruding aligning member; a second plate having a bone fixation region with at least one countersunk aperture for receiving a fastening means for affixing the second plate to the opposite side of the sternum, and a locking region dimensioned to contact at least a portion of the locking region of the first plate; and a rotating member that engages with the aligning member(s) on the first plate for holding the first and second plates together to secure the opposite sides of the sternum. The first and second plates can be separated by reversibly disengaging the rotating member from the aligning member(s).

Abstract: A threaded anchor which comprises a threaded shank portion, a tip portion defined upon one end of the threaded shank portion, and a head portion disposed adjacent to the opposite end of the threaded shank portion. The head portion comprises a hexagonally configured drive section for threadedly driving the threaded anchor into a substrate. An axially extending lug-type projection is integrally connected to the hexagonally configured drive section of the head portion, and a transversely oriented throughbore is defined within the axially extending lug-type projection so as to accommodate any one of a structural or fixture support wire or cable, a power cable, a fiber optic or telephone cable, a turnbuckle wire assembly, a support strap, a safety or guy wires, a tie down wire or cable, and the like.

Abstract: An optical film for use in transparent displays, such as reflective LCDs. The optical film has three-dimensional, prismatic structures that reflect incoming light. The prismatic structures are configured so that the reflecting facets orient the reflected light in desired reflective light pattern. The pattern shape and intensity can be controlled by the shape and dimensions of the various reflecting facets. In one embodiment, the height of the prismatic structure varies along two dimensions of the structure.

Abstract: An energy absorber for use in a personal fall arresting system. The absorber contains upper and lower webbings which are each two ply members. The back ply of the upper webbing is mounted adjacent to the face ply of the lower webbing with said webbing being of about equal length and width. Exterior tear elements run back and forth sinusoidally between attachment points on the face ply of the upper webbing and the back ply of the lower webbing. Interior tear elements run back and forth sinusoidally between attachment points on the back ply of the upper webbing and the top ply of the lower webbing.

Interior tear elements run back and forth sinusoidally between attachment points on the back ply of the upper webbing and the top ply of the lower webbing. The attachment points are formed by transverse wefts of at least one of a polyester and a para-aramid yarn in which the tensile strength of the attachment points is greater than the tensile strength of the exterior and interior tear elements.

Abstract: An actuator for actuating a gear shift mechanism in a vehicular transmission system, the actuator comprising: an actuator body (40) having an opening (43) for the transport of fluid into and out of the actuator body; an actuating member (42) within the actuator body, moveable by the fluid; and a control device (410, 416) operable to control independently the pressure of the fluid and the flow of the fluid.

Abstract: Illumination assemblies and systems using same are disclosed. The illumination assembly can include a reflective substrate, and a light source unit including one or more light sources capable of producing illumination light. The assembly can further include a first light extraction surface including an azimuthal beam widening topography, where the first light extraction surface is positioned such that the light source unit is between the first light extraction surface and the reflective substrate. The first light extraction surface can face the light source unit.
