Patents by Inventor Ruurd A. Vanderleest

Ruurd A. Vanderleest has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20140152009
    Abstract: A controller for a power generating system that includes an engine and a generator, wherein the engine provides mechanical force to the generator, which converts the mechanical force to electrical energy that is distributed via a distribution network. The controller includes a complementary filter that applies a low-frequency response to changes in the monitored power output and a high-frequency response to changes in the monitored grid frequency. The complementary filter combines outputs of the high-frequency response and low-frequency response to generate a process variable. A feedback controller generates a fuel flow value in response to the process variable.

  • Patent number: 7825721
    Abstract: Systems and methods for filtering analog signals corresponding to sensed parameters are provided. In this regard, a representative method includes: sampling the analog signal to acquire a sequential series of data points; determining a first cumulative change in value with respect to a first of the data points relative to at least two subsequent data points in the series, the subsequent data points including a second of the data points; determining a second cumulative change in value with respect to the second of the data points relative to at least two data points adjacent to the second of the data points in the series, the at least two adjacent data points including an immediately preceding and an immediately succeeding one of the data points relative to the second of the data points; comparing the first cumulative change and the second cumulative change to respective data thresholds; and outputting a filtered analog signal based, at least in part, on results of the comparing.
