This invention presents light maximization method for LED systems. Derived from a general theory that links the photometric, electric and thermal behaviours of LED systems together, the method provides the rules to design LED systems with maximum light output. Its main contribution is to provide cle.....

The universal rate control scheme can be adapted to various transuding purposes including real-time video transcoding. A new rate-distortion (RD) model is established for better characterization of the real RD feature of transcoding. A level-window rate control (WRC) algorithm is proposed for provid.....

The technology complements the on-chip monitoring of cellular reactions by exposing cells, isolated in a sandbag structure, to different concentrations of analytes or drugs in a one-step operation. The tapering microchannel structure controls the concentration and dosage of the analytes. Another maj.....

During the turn-on and turn-off switching processes, power converters have to withstand high voltage and current, leading to high switching losses and stresses. The invention is a passive lossless snubber cell with minimum stress and wide soft-switching range. The energy reset / recirculation proces.....
