Kent Allen Casey 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: 7206681
    Abstract: A vibration management system for a work machine may include at least one machine component configured to respond to input commands from an operator of the machine. One or more vibration sensors may be configured to output a signal indicative of a vibration level experienced by the operator. A controller may be configured to monitor the output signal from the one or more vibration sensors and determine an average vibration level experienced by the operator. The controller may also be configured to monitor the input commands from the operator and calculate a predicted response of the at least one machine component to at least one of the input commands. The controller may also be configured to determine a predicted vibration effect on the operator based on the predicted response and adjust an actual response of the at least one machine component to the at least one operator input command based on the predicted vibration effect and the average vibration level.

  • Patent number: 7099722
    Abstract: A control system is provided for a work machine having a plurality of removably attachable work tools. The control system has at least one operator input device that is configured to control a movement speed of the work machine. The control system also has a tool recognition device configured to generate a signal corresponding to each of the removably attachable work tools and a controller in communication with the at least one input device and the tool recognition device. The controller is configured to change a ratio of a work machine movement speed to actuation position of the input device in response to the signal.

  • Patent number: 7076954
    Abstract: A system for controlling intake pressure of a combustion engine operably coupled to a power generation system includes a sensor configured to output a signal indicative of a pressure in an intake system of the combustion engine and a sensor configured to output a signal indicative of a load on the power generation system. The system further includes a turbocharger operably coupled to the intake system. The system also includes an electric machine operably coupled to the turbocharger. The electric machine is configured to supply torque to the turbocharger. The system further includes a turbocharger controller operably coupled to the electric machine. The turbocharger controller is configured to control operation of the electric machine such that the turbocharger supplies a desired intake pressure to the combustion engine based at least partially on the signal indicative of a pressure in the intake system and the signal indicative of a load on the power generation system.
