Yukinobu Kohno 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: 10520079
    Abstract: A transmission controller comprises an actuator which changes a roller position of a toroidal CVT to adjust the tilt motion angle of a power roller; a tilt motion angle information generation unit which generates information of the tilt motion angle; a position estimation unit which derives an estimated value of the roller position; and a position control unit which derives an operation command value of the actuator so that a deviation between a command value of the roller position and the estimated value of the roller position is cancelled. The position estimation unit is configured to derive the estimated value based on the information of the tilt motion angle which is generated by the tilt motion angle information generation unit, and the operation command value, and to compensate the estimated value based on an environment parameter which affects an operation of the power roller.

  • Patent number: 7366593
    Abstract: A movable object maneuver method wherein a destination point is set; wherein a thrust value is calculated in real time which minimizes or maximizes a performance index associated with one or more state variables and thrust required for a movable object to reach the destination point and which takes into account non-linear conditions inherent to the movable object; and wherein the movable object is moved based on the calculated thrust value.

  • Patent number: 7006905
    Abstract: Force balance and moment balance associated with thrust of air and water craft equipped with thrust generators are preset in view of non-linear characteristics and dynamic characteristics of thrust generators. A performance index for minimizing thrusts generated by the thrust generators is defined. Using the balance as restricting condition, propeller thrusts of the thrust generators and rudder angles and changing speeds of rudders that minimize the performance index are calculated.
