  • Publication number: 20120220414
    Abstract: The invention relates to a continuously variable transmission (CVT) system, governed by an inertia mechanism that provides an additional degree of freedom, conferring dynamic properties on the transmission. The complete system includes three distinct subsystems. The first subsystem transforms the rotating movement from the drive system into a movement with oscillating angular speed and regulates the amplitude of said movement. The oscillating rotation at the output of the first subsystem is used to drive the second subsystem, which acts as a regulating element by means of the inertia mechanism. In this manner, the second subsystem acts as a torque-regulating element, providing a signal representing the oscillating angular speed at the output shaft thereof. The oscillating rotation at the output of the second subsystem is rectified in the third subsystem, thereby providing a signal representing angular speed in a single direction of rotation at the output shaft.

    Abstract: A mechanical device including two concentric space frame structures is used to enhance plant growth. Essentially identical in shape but with the inner space frame smaller than the outer by a 4:5 relationship the space frame structures independently rotate about a common axes line. Each space frame consists of a right square pyramid of rods with its apex pointing upward and a second similar pyramid directly below it by a distance approximately two and one half times the length of each rod comprising the pyramid. The second, lower pyramid however has its apex pointing downward and is turned 45-degrees about a line connecting the two apex points. Eight additional rods complete each space frame. They each, respectively connect a corner of the upper pyramid base to a corner of the lower pyramid base in a manner that is symmetric.

  • Publication number: 20110252819
    Abstract: An output-side swing arm is adapted to be swung about a swing axis thereof when the output-side swing arm is urged by a corresponding part of an input-side swing arm, which is driven by a force transmitted from an input shaft. An adjusting mechanism adjusts an amount of swing of the output-side swing arm by changing a location of a point of action of the input-side swing arm relative to the output-side swing arm in a radial direction of the swing axis of the input-side swing arm.

    Abstract: A steerable vehicle lighting system includes a steerable platform assembly and a control assembly. The steerable platform assembly has a body adapted to be mounted to a vehicle, a platform adapted to receive a payload and adapted to rotate with respect to the body, an actuator at least partially placed in the body, and an actuator rod rotatably mated to the actuator and rotatably mated to the platform. A rotation of the actuator rotates the platform. The control assembly includes a first wheel adapted to be placed on a rotating portion of a steering apparatus, a transducer adapted to be mated to a stationary portion of the steering apparatus, a second wheel mated to a rotatable portion of the transducer and adapted to be rotated by the first wheel, and an elastic member that elastically urges the transducer and the second wheel towards the first wheel.

    Abstract: An actuator includes an inner member that defines an inner space within which a motor is supported. An outer member is supported for rotation about the inner member. A drive slot in the inner member is shaped to cause rotational movement responsive to axial movement of a motor without relative axial movement of the outer member relative to the inner member. A drive pin moved by the motor moves within the drive slot and is engaged to a drive channel of the outer member to facilitate rotation of the outer member about the axis.
