  • Portable devices for different control interfaces
    Patent number: 7133921
    Abstract: A communications interface system and method for a plasma generator is provided. The communications interface system includes a power delivery system component that has a standard POD interface for communicating information that complies with a first protocol. A portable device is coupled between the standard POD interface and a second communication interface for communicating information therebetween. The second communication interface communicates information in a format that complies with a second protocol. The portable device is detachable from the standard POD interface and the second communication interface. A first communication link couples the standard POD interface to the portable device. A second communication link couples the portable device to the second communication interface.

  • Pulsing intelligent RF modulation controller
    Patent number: 6700092
    Abstract: A method of controlling an output of a generator is provided. The output provides an output signal having a settling time to a load having an impedance. The settling time of the output signal is determined. The output signal is amplitude modulated with a modulation waveform. A sense signal is generated that is representative of the modulated output signal. The sense signal is sampled at a sampling time based upon the settling time of the output signal. A digital representation of the sampled sense signal is generated. The amplitude modulation of the output is controlled based upon the digital representation of the sampled sense signal.
