Abstract: A powered ambulance cot and methods of raising and lowering the cot as well as loading and unloading the cot are disclosed. The cot includes a support frame and legs, each leg having a wheel. An actuator of an actuation system interconnects the frame and legs, and is configured to effect changes in elevation of the frame relative to the wheel of each of the legs. A control system controls activation of the actuation system, and detects both the actuator at a first location relative to the frame, where the first location is remote from a second location and which situates an end of the actuator that is remote from each wheel closer to the frame, and a presence of a signal requesting a change in elevation of said support frame to thereby cause the legs to move relative to the support frame.

Abstract: A high-speed sectional overhead door covers a door opening with panels stacked in a single plane and lifted from the bottom-most panel. As panels are lifted, each rolls in its own individual track. As the panels move into the head area, they run through curved tracks and are nested there. The stored panels stacked horizontally one atop another with the door open. This design utilizes a dedicated panel-track pairing as well as a unique hook/cam device which allows for the upper panel to be both locked in the closed position and pushed away for separation and storage in the open position.

Abstract: Embodiments of a method of operation of a roll-in push cot for transport onto a first surface comprising initially loading the roll-in cot onto a first surface thereby releasing automatically at least one leading leg, continuing of loading the roll-in cot onto the first surface to move a front carriage member toward a front actuator, such that movement of the front carriage member triggers the front actuator that releases a middle release lever, thereby initiating the release of at least one trailing leg, supporting the weight of the cot at least partially in order to disengage a locking mechanism for the at least one trailing leg, and loading the cot in order to move a rear carriage member in conjunction with folding of the at least one trailing leg and thereby trigger a reset actuator and release a latch pin to engage the rear carriage member when the trailing and leading legs of the roll-in push cot are in a fully folded position on the first surface.

Abstract: Embodiments of a roll-in push cot may comprise a support frame comprising a pair of lateral sides extending between a front end and a rear end, and a pair of slidable tracks disposed in the lateral sides; a pair of leading legs and a pair of trailing legs pivotally connected to the support frame; a front carriage member slidingly disposed within the pair of slidable tracks at the front end of the support frame, and a mechanical loading system coupled to the support frame and connecting the pair of leading legs with the pair of trailing legs, wherein the mechanical loading system comprises a front actuator disposed on the support frame in the motion path defined by the front carriage member, such that movement of the front carriage member triggers the front actuator and thereby initiates the release of the trailing legs.

Abstract: A garage door has pivotally connected door panels, with each of the door panels including an outer skin having an outer surface. The outer skin has a metal, such as steel, having a first coefficient of thermal expansion. An overlay element, such as a decorative element, is coupled to the outer surface of at least one of the outer skins. The overlay element includes a fiber-reinforced thermoset material having a second coefficient of thermal expansion. In one specific embodiment, the first and second coefficients of thermal expansion are substantially equal. In one embodiment, the overlay element includes a pultruded fiber-reinforced thermoset material. In yet another aspect, the overlay element is adhesively coupled to the outer surface. Adhesive coupling may, for example, include a hot-melt adhesive, a two-part glue, or double-sided adhesive tape.
