  • Ignitor spark status indicator
    Patent number: 8747102
    Abstract: An ignitor spark indicator 100 is described that monitors RF signals within a flame rod 25 located near a spark rod 23. The signal from the flame rod 25 is processed to provide a waveform that indicates when electrical arcing is occurring. The indication when arcing is occurring is also provided to flame-detecting equipment. The flame-proving device 60 only operates when the arcing is not produced so that the flame-detecting device 60 does not confuse the arcing with a flame reducing the false positive determinations.
    Type: Grant

  • Digital-storage filter
    Patent number: 4046997
    Abstract: An apparatus is disclosed for realizing analog signal filters with very long time constants. In order to avoid the losses inherent in conventional energy-storage devices such as capacitors and inductors, an analog signal is converted into digital form for storage, thereby eliminating losses, and the digital quantity is continuously converted back to analog form for use in the analog circuit.
