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 panoramic stereo imaging system is capable of providing 3D visual information in all directions with depth information. The system, installed with a camera coaxially combined with a fisheye lens and mirror, provides stereo vision over a 360-degree horizontal field of view and the entire vertical.....

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.....

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.....

The invention concerns a method and apparatus for controlling the output phase of a voltage controlled oscillator (VCO) for use in antenna arrays for receiving radio signals. Such arrays can converge energy, receive signals, and reject interference. Beam-forming techniques using phase shifters are u.....
