Patents by Inventor Charles C. Frayman

Charles C. Frayman 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: 8814103
    Abstract: A aircraft control system is provided that provides tactile feedback between control columns of the aircraft relating to discrepancies in the control inputs to the sticks of the respective control columns. In one implementation, the sticks each have an associated feedback assembly that is adjustable relative to mechanical ground to adjust the feedback profile applied to the corresponding stick. The position of each feedback assembly is adjusted based on a relative displacement between the other feedback assembly and its corresponding stick to provide active feedback relating to the control of the other control column.
    Type: Grant

  • Patent number: 8659403
    Abstract: A control stick system for simulating a detent mechanism in an aircraft is provided. The detent mechanism is simulated by a motor operably coupled to a lever and configured to bias the lever such that the user experiences the feel of a traditional detent mechanism. A controller operates the motor that provides the simulated detent by receiving data from multiple sensors regarding the position and the speed of the lever and the position and the speed of a rotor assembly of the motor. Using the position and the speed measurements, the controller is able to detect when the lever is entering a specific zone of a simulated detent range. Depending on what zone the lever is in, within the simulated detent range, the controller is configured to provide a different drive current to the motor.
