Novel methods for improving compression efficiency by compressing and encoding images are proposed in this patent. The image to be compressed is partitioned into blocks, which will then be individually analyzed to determine suitability for discrete wavelet transform pre-processing. The blocks are al.....

The invention relates to a method of manufacturing ballasts for high voltage discharge lamps. The method provides the passive LC ballast with an inductance and capacitance derived from a non-linear model. The purpose is to ensure that the lamp operates at a pre-determined lamp power. The ballast is .....
