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.....

Existing methods for multi-string applications require many windings in the isolation transformers because each converter output needs one winding. This invention, a dimmable LED driver, can reduce the number of windings. It also possesses a two-secondary-winding structure to generate several source.....

To accommodate the minimization of electronic devices, a novel process for the assembly of electronic devices on flexible substrates has been developed. The technology accommodates chip-on-flex (COF) technology which is well suited to portable display applications. The manufacturing method comprises.....

Base station antennas, set up to support wireless communications, abound in our surroundings but they are regarded by many as a health threat and therefore avoided. To mitigate the aversion felt towards base station antennas, the antennas are often hidden or camouflaged from the sight of passers-by......

Axial mode helix antennas are used as RFID base station antennas but the number of winding of helix antennas are at least 10, making them too high for use as base station antennas. To address the problem, an integrated wire elliptical helical antenna with novel cuboids dielectric resonator loading f.....
