A dynamic fixation device is provided that allows the vertebrae to which it is attached to move in flexion within the normal physiological limits of motion, while also providing structural support that limits the amount of translation motion beyond normal physiological limits. The present invention includes a flexible portion and two ends that are adapted for connection to pedicle screws. In at least one embodiment of the present invention, the normal axis of rotation of the vertebrae is substantially duplicated by the dynamic fixation device. The flexible portion of the dynamic fixation device can include a flexible anterior-posterior segment, an anterior-posterior segment bounded by one or more zones with cuts in the rod portions, a flexible accordion-like segment, and/or a hinge portion.

An orthopedic A/P cutting guide device, including a cut guide member, a support member and a positioning member for permitting both (i) rotational, and (ii) translational movement after the A/P cutting guide device has been attached to the distal femur by quick pins or other securing devices, is disclosed. Rotational movement may occur by loosening a knob thereby releasing the positioning member and the cut guide member from the support member, which may be fixed in position by the quick pins, and rotating the positioning member and the cut guide member together. Translational movement may occur by loosening a plurality of knobs thereby releasing the cut guide member from the support member and the positioning member, and moving the cut guide member anteriorly or posteriorly. After the device has been rotated and translated, the knobs may be tightened, thus securing the device from further movement.

This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to controlling tension in such continuous webs during the processing operation. Tension is controlled in a dancer control system by connecting a corresponding dancer roll to an actuator apparatus or the like, sensing variables such as position, tension, velocity, and acceleration parameters related to the web and the dancer roll, and providing active force commands, in response to the sensed variables, to cause translational movement, generally including a target acceleration, in the dancer roll to control tension disturbances in the web. In some applications of the invention, the dancer control system is used to attenuate tension disturbances. In other applications of the invention, the dancer control system is used to create tension disturbances.

A patient support structure includes a pair of independently height-adjustable supports, each connected to a patient support. The supports may be independently raised, lowered, rolled or tilted about a longitudinal axis, laterally shifted and angled upwardly or downwardly. Position sensors are provided to sense all of the foregoing movements. The sensors communicate data to a computer for coordinated adjustment and maintenance of the inboard ends of the patient supports in an approximated position during such movements. A longitudinal translator provides for compensation in the length of the structure when the supports are angled upwardly or downwardly. A patient trunk translator provides coordinated translational movement of the patient's upper body along the respective patient support in a caudad or cephalad direction as the patient supports are angled upwardly or downwardly for maintaining proper spinal biomechanics and avoiding undue spinal traction or compression.

The invention discloses a flexible display device. The flexible display device comprises a flexible display screen and a folding mechanism. The folding mechanism comprises at least two supporting pieces and at least one connecting piece, each supporting piece is movably connected with the corresponding connecting piece, and each supporting piece can rotate and conduct translational movement relative to the corresponding connecting piece, so that when the two supporting faces of each two adjacent supporting pieces are in a folded state; each two supporting pieces can move on the contrary to enlarge the gap between each two supporting faces, therefore the bending radius of a bending part is increased, and the time that a crack and a bending mark are generated on the bending part after the bending part is bent for a long time is delayed; and further the service life of the bending part is prolonged, and the using stability of the flexible display screen is improved.

The present invention relates to a method for moving a piston rod in an injection device, the piston rod being operatively connected to a motor shaft of an electrical motor so that a rotational movement of the motor shaft is transformed to a translational movement of the piston rod, the piston rod being adapted to be moved between two end positions, the method comprising the steps of providing a first supply voltage level to the electrical motor, measuring sets of corresponding values of current provided to the motor and a corresponding position of the piston rod, and providing a second supply voltage level to the electrical motor when the measured position of the piston rod equals predetermined positions, the second supply voltage level having a RMS value being smaller than the RMS value of the first supply voltage level.

A belt and tread drum having an annular shell comprising a plurality of circumferentially spaced segments, each of which is mounted on a carrier which disposed in circumscribing relationship to a generally cylindrical actuator rotatably connected with a reciprocating piston disposed within a cavity defined between the actuator and a hub fixed to a central core of the drum. Translational movement of the piston between extended and retracted positions in a direction parallel to the rotational axis of the drum is converted into selected rotational movement of the actuator relative to the hub. A plurality of sets of links interposed between the segments and the actuator and hub have their first ends commonly pivotally pinned to a segment. The second end of one link of each set of links is pivotally pinned to the actuator and the second end of the other link of each set of links is pivotally pinned to the hub. Rotation of the actuator relative to the hub controls the arcuate separation of these second ends such that bringing these second ends toward contiguity moves the segments radially outwardly, and conversely, moving these second ends arcuately apart serves to move the segments radially inwardly of the drum. A hand wheel establishes maximum and minimum rotational movement of the actuator and provides a visual indication of the radial positions of the several segments, i.e. the diameter of the drum.
