Abstract: A LED light fixture and a luminous flux monitoring system for a light fixture. The light fixture includes a housing defining an interior space including an interior surface and a transmissive panel. A light source is coupled to the interior surface. The system includes a light sensor coupled to the interior surface and aligned to receive light from the transmissive panel, light source, and/or interior surface. The light sensor is configured to measure luminous flux in the interior space. A controller is coupled to the light source and the light sensor. The controller is configured to determine if a light sensor measurement of luminous flux in the interior space is more or less than a reference value of the luminous flux. If the measurement of luminous flux is less than the reference value, the controller is configured to activate an end-of-life indicator. The reference value equals (total flux?internal ambient flux)×depreciation factor.

Abstract: A cable protection system protects a cable, such as an insulated conductor, data line, fluid or gas conduit, power cord, communication line or the like. The cable passes through a pair of ferrules that are separated by a segment of the cable. A protective jacket made of braided metal strands or the like encloses the ferrules and the cable segment and is held in place to the ferrules by jacket securing means. In one embodiment, support collars surround a portion of the braided jacket and a portion of each ferrule so that the braided jacket is securely held between each ferrule and support collar combination when a loading force, such as a gravitational loading or suspension force, is applied to the cable segment, typically in an axial orientation. The braided jacket has a diameter that constricts when an axial loading force is applied, protecting the cable segment from damaging stress by gripping the ferrules and the cable segment.

Abstract: A lighting fixture housing includes two end caps, a reflector assembly, and a ballast box cover. The two end caps further include top and bottom flanges and mounting brackets having support tabs extending thereon. The lighting fixture housing is installed by first sliding the end caps into position at opposite ends of an opening in a suspended ceiling formed of a T-bar grid, and then attaching the reflector assembly to the end caps. The reflector assembly may be temporarily suspended from the end caps so that electrical connections to the assembly are made and the ballast box cover installed.

Abstract: The present invention provides for an ECG electrode system that includes the use of electrodes adapted to attach to the body via suction. The invention includes a lightweight and compact air pump in combination with air connection hoses, a lightweight air distribution unit, associated electrode tubes, and respective electrodes adapted to be positioned by the Venturi principle, and corresponding electrical leads and recorders/monitors. The electrode leads can each be positioned within respective air connections hoses, e.g., in a manner that is concentric or coaxial with the axis of the connection hoses, in order to both protect the leads themselves and facilitate their positioning.

Abstract: A contactor for establishing electrical Communication with organic tissue, the contactor including a cup-shaped housing of one-piece rubbery material including a closing end-wall connected across an annular sidewall with rice defining an open mouth into a main recess. An electrode in the recess corgi a contact plate with first side facing the mouth to contact organic tissue, and a second side with a pair of leg-like extensions and a center limiter post ail of one-piece molded plastics coated with a thin layer of conductor preferably silver/silver chloride to be electrically conductive on the exterior surface of the electrode. The legs of the electrode snap fit against to physically and electrically connect with an electrically conductive venturi tube mounted extending through the housing, the venturi tube having a suction port positioned such that when high pressure gas is passed through the venturi tube, a vacuum is created within the housing recess.
