| 20100186527 | CENTRIFUGAL SYSTEM - A centrifugal system transmits a centrifugal force from a favorably positioned rotational object with a mass element to an arm that is coupled to an output axle or directly to the axle or a structure on the system, so as to provide output torque or force. The centrifugal system uses rotational motion of one or more mass elements in an object to create a centrifugal force that drives the mass elements radially outward, so that the centrifugal force creates a tangential force which acts at an angle on an arm to provide a significant amount of torque to rotate an output axle of the system. The centrifugal force of the system may also be used to create force output for the system. The angle is the angle between a connection element and the arm or axis of rotation. The angle determines the magnitude of the effective force for torque or force creation. The objects—particularly, their mass elements—of the centrifugal system are designed to drive the arms of the torque system mechanically or create a force on the force system. Objects may have adjustable connection elements or connection element configurations, such that the objects impart energy for the arms to rotate centrifugal system. The torque achieved in a torque system or the force achieved in a force system can be controlled by adjusting the amount of centrifugal forces created by the objects. The centrifugal system may be in open space or enclosed. Various considerations of system configuration, object configuration, object mass, connection locations, location of mass to the axis of rotation, torque arm length, and angle of centrifugal force are design parameters that can be tuned to achieve high performance. The torque created can be used to drive rotary motion of an output axle, for example. The force created can be used to drive linear motion on an output axle or the system, for example. | 07-29-2010 |

| 20140123787 | GEARED INFINITELY VARIABLE TRANSMISSION - An infinitely variable transmission (IVT) to provide a continuous output-to-input speed ratio from zero to a certain value is designed, and its working principle is illustrated. It is a geared IVT (GIVT), since its function to achieve the continuously varied speed ratio is implemented by gears. Crank-slider systems are used in the GIVT; the output-to-input speed ratio is changed with the crank length. Racks and pinions, whose motion is controlled by planetary gear sets, are used to change the crank length when the cranks are rotating. One-way bearings are used to rectify the output speeds from different crank-slider systems to obtain the output speed of the GIVT. Since the crank-slider systems can introduce variations of the instantaneous speed ratio, a pair of noncircular gears is designed to minimize the variations. A direction control system is also designed for the GIVT using planetary gear sets. Finally, a vehicle start-up simulation and a wind turbine simulation to maintain a constant generator speed are developed based on a GIVT module in the Matlab Simulink environment. | 05-08-2014 |
