Abstract: A hand-held light treatment device configured with interchangeable emitter heads that are pre-programmed with desired treatment protocols and updated from a remote store of treatment protocols. The device comprises a handpiece, a plurality of emitter heads, and a base. The removable emitter heads each contain one or more treatment LEDs, a tracking light, a task light, a proximity sensor, and a control module. A tip is attached to the emitter head, either removably or integral therewith. In one embodiment, the tip is integral with the emitter head and emits light to the side of the device, perpendicular to the handpiece. The device is prohibited from emitting light when too far from a surface. Some embodiments have disposable tips of various shapes that attach to the emitter heads, which permits a single device to direct the emitted energy at nearly any direction and be used in a variety of applications.

Abstract: An apparatus for exposing laundry to ultraviolet (UV) light comprises a mobile unit having a housing and at least one UV light carried by the housing and directed exteriorly therefrom. An activation module is located in the housing and configured to supply electrical power to the at least one UV light only when at least one activation criterion is satisfied. A battery power unit located in the housing supplies the electrical power to the at least one UV light via the activation module. The mobile unit can be connected to a base unit located on an interior surface of a laundry machine door. A UV light-sensitive laundry sheet can be used to gage UV light exposure to the laundry.

Abstract: A light housing is provided. Housing comprises plate with light communication for LED luminaire attached to upper surface of plate, annular base having a rim, plurality of supports connecting plate to annular base, slots in each of plurality of supports; and retention clips engaged within slots. Housing includes j-box rotatably secured by support to plate with mounting brackets which include locking detents to maintain support in upper or lower positions. Also provided is fixture assembly comprising housing with LED light attached thereto. Further methods for installing assembly are provided and include positioning assembly through hole in ceiling substantially within above-ceiling space, locking retention clips against plurality of supports to maintain assembly in position relative to ceiling; and engaging upper rim of reflector with deflection clips attached to bottom surface of plate of assembly.

Abstract: An extension ladder includes a pair of nested outer and inner ladder rails. Ladder rungs connected between and the inner rails define a plurality of supporting openings and the inner rails include outer bearing surfaces associated with the supporting openings. An extension latch mechanism having a pivoting dog is coupled to an outer rail and engages the supporting openings and outer bearing surfaces to support the ladder in an extended position.

Abstract: A folding ladder includes a hinge assembly having first and second ladder hinge plates each defining a plate opening and a plurality of locking slots. A housing is associated with the first ladder hinge plate and extends through the plate openings to provide a rotation axis for the plates, and the second plate is operable to rotate relative to the first plate about the rotation axis to selectively align slots of the first and second plates. A key outside the housing selectively engages aligned slots to selectively prevent rotation of the ladder hinge plates about the rotation axis and is operated by a manual rotation member. An extension ladder includes a pair of nested outer and inner ladder rails. Ladder rungs connected between and the inner rails define a plurality of supporting openings and the inner rails include outer bearing surfaces associated with the supporting openings.

Abstract: The present invention discloses a method of preventing acute pulmonary cell injury associated with ALI or ARDS and a method of inhibiting an inflammatory response in pulmonary cells by increasing levels of HSP70 protein.
