20130147205 | INTEGRATED ENERGY GENERATING DAMPER - A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of to the energy harvesting apparatus can be dynamically altered. In another mode, the apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators. | 06-13-2013 |

20140288776 | ACTIVE VEHICLE SUSPENSION - A method of on-demand energy delivery to an active suspension system is disclosed. The suspension system includes an actuator body, a hydraulic pump, an electric motor, a plurality of sensors, an energy storage facility, and a controller. The method includes disposing an active suspension system in a vehicle between a wheel mount and a vehicle body, detecting a wheel event requiring control of the active suspension; and sourcing energy from the energy storage facility and delivering it to the electric motor in response to the wheel event. | 09-25-2014 |
20140294625 | CONTACTLESS SENSING OF A FLUID-IMMERSED ELECTRIC MOTOR - A method and system for measuring rotor position or velocity in an electric motor disposed in hydraulic fluid. The system comprises a contactless position sensor that measures electric motor rotor via magnetic, optical, or other means through a diaphragm that is permeable to the sensing means but impervious to the hydraulic fluid. An electronic sensor is positioned outside the operating fluid, whereas the motor is located in the fluid volume. | 10-02-2014 |
20140297113 | ACTIVE STABILIZATION SYSTEM FOR TRUCK CABINS - An active suspension system for a truck cabin that actively responds to and mitigates external force inputs between the truck chassis and the cabin. The system greatly reduces pitch, roll, and heave motions that lead to operator discomfort. The assembly is comprised of two or more self-contained actuators that respond to commands from an electronic controller. The controller commands the actuators based on feedback from one or more sensors on the cabin and/or chassis. | 10-02-2014 |
