A patient support surface comprises a cover defining an interior region, a modifiable support layer situated in the interior region and having at least one air bladder, and a sensor layer situated in the interior region and having at least one sensor configured to detect a physiological parameter of a patient atop the patient support surface. The voting cart includes portable voting booth trays that can be deployed from the voting cart with privacy shields that are formed integral and can be erected for privacy. The visual guide may include one or more shot arrow and corresponding clubface lines for different types of shots. An alternate embodiment of the present invention utilizes a combination of a cylindrical container with the wrapped munition device. An x-ray image having multiple energy differentiable characteristics is generated in response to the x-ray beam. The interferometric modulators have a plurality of states, wherein selected ones of the interferometric modulators are configured to be actuated depending differing electrostatic forces in the interferometric modulators.
