With a total of 3 patents to her name, her work has had a meaningful impact on the industry.
Latest Patents
One of her latest patents is titled "Modified trimmed mean filtering for misfire detection." This invention involves a modified trimmed mean filtering method and apparatus for misfire detection, which includes acquiring a time-continuous series of acceleration data samples representative of the acceleration behavior of a reciprocating engine. The method provides a filtered acceleration data sample dependent on an average acceleration magnitude of a portion of the acceleration data samples bounded within a range of amplitudes. A misfire condition can be indicated based on the magnitude of the filtered acceleration data sample. Another significant patent is "Detrending engine positional data for rotating position encoders." This method includes acquiring positional encoder data over a plurality of consecutive engine revolutions as the engine is decelerating. It identifies a trend in the acquired positional encoder data consistent with behavior occurring at less than a frequency of one cycle per engine revolution and generates corrected positional encoder data by removing the identified trend.
