Patents by Inventor Keith Calhoun

Keith Calhoun 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).

  • Patent number: 10941725
    Abstract: The disclosure includes a system that includes an adaptive control module for an engine. The adaptive control module is configured to receive a power input signal and receive, from an engine vibration sensor, a vibration signal indicative of an operating condition of the engine. The adaptive control module is further configured to determine, using a set of control laws, a power demand signal based on inputs including the power input signal and the vibration signal. The adaptive control module is further configured to output the power demand signal to at least one component of the engine.

  • Publication number: 20130116937
    Abstract: In one embodiment, a method is provided for detecting a fault condition in a drivetrain, including the steps of monitoring torque oscillations at a location along a drivetrain, and detecting at least one fault condition associated with a drivetrain component by evaluating torque oscillation data acquired during the monitoring. In another embodiment, a system is provided for detecting a fault condition in a drivetrain including a torque sensor coupled to a drivetrain component and configured to measure torque at a location along the drivetrain and to generate a torque oscillation signal corresponding to the measured torque, and a controller configured to receive the torque oscillation signal and evaluate the torque oscillation signal to identify at least one fault condition associated with the drivetrain component.
