Latest Patents

One of his latest patents is titled "High sensitivity brush arcing monitor for a dynamoelectric machine." This invention discloses high noise immunity instrumentation for monitoring brush arcing in dynamoelectric machines. The instrumentation includes a stabilized variable threshold discriminator that operates in conjunction with a feedback network and a non-linear high-frequency amplifier. This setup provides a discriminator threshold that increases with rising background noise levels, ensuring that only the arc indicative portions of the signal are passed. This results in a substantial increase in the signal-to-noise ratio. The feedback network features a relatively long time constant integrator and buffer amplifier. Additionally, an alarm network is included to alert users upon the occurrence of brush arcing, continuously comparing the arc indicative signal with a reference signal that adjusts automatically for changes in the average signal level.

Another significant patent is the "Apparatus for monitoring arcing of brushes in a dynamoelectric machine." This apparatus monitors arcing of brushes used in transferring current signals to and from the field of a generator. It analyzes electrical signals from the brushes, which may include brush arcing signals and high-amplitude noise spikes. A two-stage clipping network is incorporated to enhance the brush arcing/noise ratio, mitigating the masking effect of noise spikes without losing sampling intervals during arcing occurrences. The monitor also features discriminator diodes biased for constant threshold sensitivity, an alarm system to indicate and record brush arcing occurrences, and a reference signal generator that adjusts for changes in generator noise levels.
