Devices consisting of both curved mirrors and conventional lenses systems are known as catadioptrics. Catadiopotrics can shorten the overall optical path length and therefore are popular in telescopes and telescopic camera lenses. This invention aims to develop catadioptric systems capable of genera.....

Worldwide electricity demand will rise to 30,116 billion kilowatt-hours in 2030 which is more than double the 2003 level. To control the energy demand and increase the electricity generation efficiency, we have developed a ZigBee wireless sensor network for advanced metering infrastructure. The syst.....

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......
