  • Infinitely variable transmission hydraulic hybrid for on and off highway vehicles
    Patent number: 7793496
    Abstract: An infinitely variable transmission for use with an internal combustion engine is provided. Specifically, a prime mover is provided for driving a first hydraulic machine. The first hydraulic machine is arranged to drive a second hydraulic machine via a fluid line that connects the first and second hydraulic machines. The second hydraulic machine is operatively connected with an output element, such as a wheel to drive a vehicle. Each of the first and second hydraulic machines have electronically controllable valves for varying the speed and/or the torque of the first and second hydraulic machines thereby providing an infinitely variable transmission.

  • Method and apparatus for calibrating a variable force solenoid
    Patent number: 6631633
    Abstract: A variable force solenoid valve assembly generally includes a coil, magnetic pole, armature, and one or more variable size air gaps that are disposed within the solenoid. The solenoid may be calibrated by first energizing the solenoid coils and determining a corresponding desired hydraulic pressure, measuring the actual hydraulic pressure, and adjusting the magnetic flux until the desired output pressure is achieved.
