Abstract: A modular patient support apparatus includes mechanisms, which provide advanced kinematics for moving portions of the patient support apparatus. The patient support apparatus includes a releasing assembly connected to the head deck section that assists in the raising and lowering of the head deck section by unlocking an adjustable-length strut. The patient support apparatus includes an over-center calf deck section mechanism that assists the user in pulling or holding calf deck section up when at or near a flat position, reducing the amount of input force needed to articulate the calf deck section, and self-retracting the calf deck section down when the calf deck section is at or near the fully articulated position.

Abstract: Each of an optical component, a laser apparatus that includes the optical component and a method for operating the laser apparatus uses a particular reflective material layer located and formed over a substrate at a particular thickness for providing the optical component, the laser apparatus and the method for operating the laser apparatus with sufficient imperviousness to laser filaments under particular energy density fluence considerations. A particular reflective material layer comprises gold or a gold alloy. Other reflective materials may include silver, copper, aluminum and palladium reflective materials and related alloys.
