    摘要: An apparatus for clock generation is presented. In one embodiment, the apparatus comprises a phase interpolator that generates an output with a phase value within reference phases associated with two input clocks. Logic units are coupled to determine a number of phase settings for the phase interpolator. A divider is coupled to the phase interpolator to generate an output clock based on a modifiable divider setting.

    摘要: A braking system for a movable unit which travels along a cable includes a plate of conductive material extending from the cable to define a braking zone having a start and an end along at least a portion of the cable. There is a brake unit movable along the cable and positionable at the start of the braking zone. The brake unit has magnets positionable on opposite sides of the conductive material. The brake unit is engagable by the movable unit when the movable unit reaches the start of the braking zone to couple the two units together. The movable unit acts to push the brake unit through the braking zone such that movement of the magnets of the brake unit relative to the conductive material induces eddy currents in the conductive material to create a braking force between the brake unit and the plate of conductive material to brake the brake unit and the movable unit. In an alternative arrangement, the magnets are installed directly in the movable unit to eliminate the separate brake unit. The braking system provides for reliable, low ‘g’ force, high energy absorption operation in all weather conditions with minimal maintenance.
