Abstract: A fiber optic cable includes a cable core of core elements and a protective sheath surrounding the core elements, an armor surrounding the cable core, the armor comprising a single overlap portion when the fiber optic cable is viewed in cross-section, and a jacket surrounding the armor, the jacket having at least two longitudinal discontinuities extruded therein. A method of accessing the cable core without the use of ripcords includes removing a portion of the armor in an access section by pulling the armor away from the cable core so that an overlap portion separates around the cable core as it is being pulled past the cable core. A protective sheath protects the core elements as the armor is being pulled around the cable core.

Abstract: A personal thermoelectric-cooling and heating case includes a first rigid chamber and a temperature regulated second rigid chamber. The first rigid chamber accommodates electronic circuitry. The first rigid chamber also extends lengthwise along a longitudinal axis and includes a first end portion, a second end portion, and a thermoelectric-cooling device. The temperature regulated second rigid chamber includes a bay structure configured to accommodate an item that is subject to temperature regulation. The temperature regulated second rigid chamber (i) extends lengthwise along a longitudinal axis and includes a first end portion and a second end portion, (ii) is coupleable to the first rigid chamber in a lengthwise direction, and (iii) includes a direct heating element thermally coupled to the bay structure. The first rigid chamber and the temperature regulated second rigid chamber together form a housing.

Abstract: A luminaire includes a lightguide, end caps on respective ends of the lightguide, a contact block with a pair of apertures for receiving a pair of suspension cables, one or more light emitting diodes (LEDs) disposed within each end cap to project light into an edge of the lightguide, and a pair of suspension cables to support the luminaire and provide electrical power to the LEDs. A configurable power supply box, to be mounted to a ceiling or above a drop ceiling to provide power to the luminaire via the suspension cables, is also disclosed.

Abstract: A direct-indirect luminaire including a pair of sockets for receiving at least one tubular fluorescent lamp; a louver, arranged on one side of the lamp socket, for controlling downlight from the lamp; and a shutter, arranged on an opposite side of the lamp socket, for controlling uplight from the lamp. The shutter may include a plurality of adjustably sizeable apertures which may be formed by adjacent members that are slidable relative to each other, with matching patterns of overlapping openings. The adjacent members may further include nested concave surfaces facing the lamp, such as channel-shaped members with openings that are arranged on at least two walls of the channel. A positioner may also be provided for designating a size of the apertures. For example, the positioner may include a protuberance on one of the adjacent members for engaging a hole in the other of the adjacent members.
