摘要： The present application describes various embodiments of systems and methods for internal components for portable computing devices relating to keyboard components and keyboard backlighting. In one embodiment, a keyboard module can include a rectangular light guide panel and a driver board including discrete light sources mounted on the driver board where the driver board is disposed along one edge of the light guide panel and light emitted for the discrete light sources is captured by the light guide panel and distributed to predetermined locations.

摘要： A polyolefin production system, comprising a polymerization reactor (such as a polyethylene loop slurry reactor) and a fractionation system that receives reactor effluent processed in a diluent/monomer recovery system for recycle to the reactor and to suppliers. A conduit diverts a portion of a reflux flow comprising monomer, such as ethylene, from within the fractionation system to the polymerization reactor, providing for less venting of monomer, such as ethylene, to the supplier. Accordingly, monomer yield is advantageously increased, as the monomer returned to the reactor displaces monomer feedstock to the reactor. The reflux flow may originate from a condensed overhead lights from a diluent recycle column disposed in the fractionation subsystem. The diluent recycle column may receive a stream comprising diluent and monomer as feed from the diluent/monomer recovery subsystem, and may receive the non-diverted portion of the reflux flow as reflux.
