A resonant power converter for ultra-efficient radio frequency transmission and associated methods. In one exemplary embodiment, the invention is digitally actuated and uses a combination of a noise-shaped encoder, a charging switch, and a high-Q resonator coupled to an output load, typically an antenna or transmission line. Energy is built up in the electric and magnetic fields of the resonator, which, in turn, delivers power to the load with very little wasted energy in the process. No active power amplifier is required. The apparatus can be used in literally any RF signal application (wireless or otherwise), including for example cellular handsets, local- or wide-area network transmitters, or even radio base-stations.

Resonant power converter for radio frequency transmission and method

This invention relates to an improved method and apparatus for the detection and measurement of concentrations of foreign substances in a fluid, particularly atmospheric gas. Transducers and signal modifying devices are electronically connected in a predetermined arrangement so as to determine the concentration of foreign matter and display this concentration as a linear function determined by the amount of foreign matter found.
