A system and method for reducing vibration of a cantilevered patient support surface are provided herein. A system includes a spring and roller coupled with the spring. The spring creates an upwards spring bias on the patient support surface. The roller is coupled with the spring via a roller lever arm. A frictional resistance at the roller arm and an upward directed spring bias enables the roller to maintain constant contact with the patient support surface.

Reducing vibration of a cantilevered patient support surface

Systems, methods and apparatus are provided through which, in some embodiments, an extending column is comprised of a plurality of stacked slides that are mounted to each other through linear bearing assemblies that allow the extending column to telescope inward and outward. Some embodiments of the extending column have a synchronization mechanism between each slide to extend each slide in equal distances relative to each other.

Systems, methods and apparatus of an extending column

A deployable crossed log periodic dipole array is made up of a plurality of bays spaced along a feed transmission line arrangement. Each bay includes a support centered on the array axis. Each bay also includes as antenna elements four long, straight, flat or slightly bowed springs or spring-like tape elements, each fastened at one end to a transmission line conductor. A retainer associated with each bay is rotatable about the cylindrical support and engages the spring elements, so that rotation of the retainer winds the spring elements against the spring resistance and stores energy therein. A locking arrangement simultaneously engages or disengages all the retainers. Simultaneous unlocking of the retainers allows the springs of all the bays to rotate the retainers and to unwind. As the springs unwind, they deploy. The transmission line arrangement includes two open two-wire transmission lines on a common axis. To reduce torques during deployment, each bay contrarotates relative to an adjacent bay. The locking arrangement is a longitudinal rod with projecting pins which can simultaneously engage the support structure and the rotatable retainer. The rod is actuated by a cam in a hinge.
