A patient-support apparatus that comprises a base, a patient-support deck having a longitudinal length and a transverse width, and a deck-positioning assembly coupling the patient-support deck to the base. The patient-support deck is supported with respect to the deck-positioning assembly for longitudinal movement. The deck-positioning assembly includes an actuator having a first portion and a second portion that moves transversely relative to the first portion. The deck-positioning assembly includes a transmission assembly configured to convert transverse movement of the second portion relative to the first portion into longitudinal movement of the patient-support deck relative to the base.

Apparatus for positioning a patient-support deck

A computer controlled hydraulic resistance device for apparatus such as a prosthetic knee for above knee amputees, includes a solenoid actuated valve connected to control the flow of hydraulic fluid to and from a hydraulic actuator which applies resistance to the prosthetic knee or other apparatus through a coupling. Hydraulic pressure is sensed on the high and low side of the actuator and is used by a micro-controller in a closed-loop manner to compensate automatically for variations in the device and in the hydraulic fluid viscosity. The device also senses the position of the apparatus and feedsback to the micro-controller for applying a predetermined resistance profile to the apparatus.
