Abstract: A scanning camera includes a camera assembly associated with curved scan paths. Each camera assembly includes an image sensor and a lens, and has a camera optical axis. Also included are a scanning mirror, and a drive to rotate the scanning mirror about a spin axis, which is tilted relative to the camera optical axis, according to a spin angle. The scanning mirror is tilted relative to the spin axis. For each camera assembly, the scanning mirror is tilted relative to the camera optical axis, and is positioned to reflect an imaging beam into the lens. A viewing angle and a viewing direction of the imaging beam relative to the object plane varies with the spin angle and a pointing direction of the camera optical axis. Each lens focuses the imaging beam onto its respective image sensor, which captures each image along a respective scan path.

Abstract: A system and method for positioning an article under a person are provided. The system includes an apparatus having a first cover structure and a second cover structure, each having a first surface and a second surface opposite the first surface. The first surface is movable in a first direction and the second surface moves in a second opposite direction. A coupling structure couples the first cover structure and the second cover structure, spacing them to enable the article to be positioned therebetween. The first and second directions of the first and second cover structures are substantially aligned. Movement of the first surfaces of the first and second cover structures in the first direction causes the second surfaces of the first and second cover structures to move the article positioned therebetween in the second direction by the second surfaces.
