Abstract: A display-based user illumination system includes a memory that is configured to store program instructions and one or more processors operably connected to the memory. The program instructions are executable by the one or more processors to control a display device to display content to a user of the display device on a first area of a display screen of the display device. The program instructions are executable by the one or more processors to control the display device to provide an edge light along a different, second area of the display screen by emitting a constant light from the second area for an extended period of time to illuminate the user of the display device.

Abstract: A computing device can include a chassis; a circuit board coupled to the chassis; a processor operatively coupled to the circuit board; and memory accessible by the processor; where the chassis includes a first end, an opposing second end, a first side that includes feet, and an opposing second side that includes feet, and where at least one of the first end and the second end includes an electrical component that is positioned closer to one of the first side and the second side.

Abstract: A computer system having an opening configured to accept a device, the device assembly including at least one engagement surface. 3The computer system comprises a locking mechanism disposed in the opening to releasably latch the device assembly in the opening at a preselected position. The latching mechanism includes a hand actuated assembly movable in the opening for releasably engaging the engagement surface of the device assembly when the device assembly is located in the opening. The invention also contemplates the combination of the device assembly and the computer.

Abstract: An apparatus, system, and process for demarking a control object using direct non-visible light is disclosed. A non-visible light reactive compound is applied to the control object. In one embodiment, the non-visible light reactive compound forms a designator. A non-visible light source directly radiates the non-visible light reactive compound. The non-visible light reactive compound reacts to the non-visible light by radiating visible light, illuminating the non-visible light reactive compound. The illuminated non-visible light reactive compound demarks the control object. In one embodiment, the non-visible light source is an ultraviolet light source and the non-visible light reactive compound is an ultraviolet reactive compound.
