Abstract: A linear lighting device may include an elongated housing that defines a cavity. The linear lighting device may include plurality of emitter printed circuit boards configured to be received within the cavity. Each of the plurality of emitter printed circuit boards may include a plurality of emitter modules mounted thereto. Each of the plurality of emitter printed circuit boards may include a control circuit configured to control the plurality of emitter modules mounted to the respective emitter printed circuit board based on receipt of one or more messages. The linear lighting device may include a total internal reflection lens for each of the plurality of emitter printed circuit boards. The total internal reflection lens may be configured to diffuse light emitted by the emitter modules of the plurality of emitter printed circuit boards.

Abstract: A rack system for housing electronic and/or electrical equipment is provided comprising a rectangular base frame, a rectangular top frame, and four elongated vertical support members each extending along a longitudinal axis between and joined to two associated corners of the rectangular base frame and the rectangular top frame. The rectangular base frame, rectangular top frame, and the four elongated vertical support members may be constructed from members having the same substantially A-frame cross-section. Each support member may be constructed from an elongated sheet material extending along a longitudinal axis by bending the sheet material about an axis parallel to the longitudinal axis of the sheet material to form at least three elongated sections, where a first section and a second section are adjacent and substantially perpendicular to each other and a third section extends between approximately mid-point of the first section and approximately mid-point of the second section.

Abstract: An umbrella having a sprinkler device comprises an umbrella body and a sprinkler device. The umbrella body comprises a plurality of upper spokes and lower spokes, an upper spoke holder, a lower spoke holder and a shaft portion. One end of each upper spoke and lower spoke are respectively engaged with the upper and lower spoke holder such that the upper and lower spokes are radially disposed respectively. The other end of each lower spoke supports the corresponding upper spoke. The sprinkler device comprises a multi-link nozzle, a main hose, a plurality of tubes and spouts. One end of the main hose connects with the primary nozzle of the multi-link nozzle. One end of each tube connects with its corresponding secondary nozzle of the multi-link nozzle, and the other end thereof connected with a spout. Water is channeled through the multi-link nozzle to each tube and sprayed by each spout.
