20100097017 | SYSTEM AND METHOD FOR CONTROLLING POWER BALANCE IN AN ELECTRICAL/MECHANICAL SYSTEM - An electrically commutated actuator and control system has a stator and a shaft that is movable with respect to the stator. A plurality of magnets movable with the shaft provide a first magnetic flux, and an electric current in at least one coil defined on the stator provides a second magnetic flux. The second magnetic flux is controlled in response to the first input so that the second magnetic flux has a predetermined phase with respect to the first magnetic flux. The second magnetic flux is controlled in response to the second input so that the phase of the second magnetic flux with respect to the first magnetic flux varies from the predetermined phase. | 04-22-2010 |
20110160959 | Surface Vehicle Vertical Trajectory Planning - An active suspension system for a vehicle including elements for developing and executing a trajectory plan responsive to the path on which the vehicle is traveling. The system may include a location system for locating the vehicle, and a system for retrieving a road profile corresponding to the vehicle location. | 06-30-2011 |
20130221625 | Actuator Assembly - An actuator assembly for use in an active suspension includes a drive assembly having a first portion and a second portion configured to translate relative to each other. The first portion is coupled to a sprung mass and the second portion is coupled to an unsprung mass. The actuator assembly includes an air spring assembly disposed about the drive assembly having a first portion disposed in proximity to the sprung mass and a second portion disposed in proximity to the unsprung mass, the air spring assembly defining an air volume pressurized at an air pressure greater than atmospheric pressure. The actuator assembly includes a cooling assembly having a set of drive assembly channels disposed within the air volume and in thermal communication with the drive assembly and a pump disposed in fluid communication with the set of drive assembly channels. | 08-29-2013 |
20130249464 | Actuator Assembly with Preloaded Ball Screws - An actuator assembly includes a first motor having a first transmission mechanism, a second motor having a second transmission mechanism, and a drive shaft operatively coupled to the first transmission mechanism of the first motor and the second transmission mechanism of the second motor. The actuator assembly includes a torque application system disposed in operative communication with the first motor and the second motor, the torque application system configured to direct an application of a translation torque and a preload torque between the first motor and the first transmission mechanism and between the second motor and the second transmission mechanism. | 09-26-2013 |

20140316661 | Seat System for a Vehicle - A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. One or more sensors can each measure an aspect of motion. A processor can (i) receive input from each of the one or more sensors, (ii) determine from this input a measure of rotation of the vehicle away from a nominal, level horizontal orientation, and (iii) utilize the input to determine a desired rotation of the seat. An angle that the seat has been rotated away from a nominal, level orientation is more than insubstantially larger than an angle that the vehicle has rotated away from a nominal, level horizontal orientation. | 10-23-2014 |
