Number	Title	Issue Date
7382208	Operating method for the resonant operation of high-pressure lamps in longitudinal mode, and an associated system and electronic ballast The operating method is based on the simultaneous application of FM and AM. In this process, the fundamental frequency of the AM is derived from at least one, preferably the second, longitudinal mode. In continuous operation of the lamp, the color temperature is set...	06/03/2008
7359472	Method and apparatus for wireless data transmission A method and apparatus for wireless data transmission between a base station and one or more, in particular, passive and/or backscatter-based transponders, in which the base station modulates a carrier signal with a modulation signal, to generate synchronization mar...	04/15/2008
5896182	Amplitude modulator Amplitude modulator comprising a differential input pair receiving a modulating input signal, and a Gilbert cell multiplying a carrier signal by the modulating input signal; and a second differential pair of transistors receiving the carrier signal, and t...	04/20/1999
