Embodiments of a peripheral backlighting system for keyboards are shown and described, which include one or more light-emitting panels exterior to the keyswitches of the keyboard. The panels are preferably electroluminescent material or light-emitting chemical cells and surround at least two sides, and preferably all sides, of the actuation portion of a keyswitch or the space in which the actuation portion slides up and down during use. Alternatively, the panel(s) may extend substantially continuously between and underneath a plurality of keyswitches. The panels extend closely adjacent to the actuation portion or actuation path, or under the keyswitch, to be as far under the key cap as possible without extending into the keyswitch. Preferably, the keyswitch is translucent or partially translucent, and the housing plate over the light-radiant panels, if any, is at least partially translucent or transparent. This way, the light from the light-emitting panels radiates upward through, and preferably around the outer surface of, the translucent keycaps, rather than up through an aperture or lightpipe in the center of the keycaps.

Computer keyboard backlighting

Embodiments of a peripheral backlighting system for keyboards are shown and described, which include one or more light-emitting panels exterior to the keyswitches of the keyboard. The panels are preferably electroluminescent material and surround at least two sides, and preferably all sides, of the stem of a keyswitch or the space in which the stem slides up and down during use. Alternatively, the electroluminescent panel(s) may extend substantially continuously between and underneath a plurality of keyswitches. The panels extend closely adjacent to the stem or stem path, or under the keyswitch, to be as far under the key cap as possible without extending into the stem or cap of the keyswitch. The EL panels are preferably powered by the computer keyboard port, via voltage inverters. Preferably, the keyswitch is translucent or partially translucent, and the base plate over the EL panels, if any, is at least partially translucent or transparent. This way, the light from the light-emitting panels radiates upward through, and preferably around the outer surface of, the translucent keycaps, rather than up through an aperture or lightpipe in the center of the keycaps.

Backlighting for computer keyboard

The present invention comprises a heating wrap for placement against an injured/painful area of a person's body and an analgesic cream being placed between the heating wrap and the injured/painful area. The invented cream is formulated specifically for use with a heating wrap to be heat-compatible. The added heat from the heating wrap enhances the permeability of the skin and the tendency of the cream to permeate into the skin. The cream preferably includes an ingredient pharmaceutically categorized as an analgesic agent and an ingredient pharmaceutically categorized as an anti-inflammatory agent. Preferably, the cream does not include ingredients at levels that irritate human skin at the elevated temperatures of the heating wrap, that is, at about 110-140 degrees F. wrap temperatures. The heat wrap may be a pad that includes a flexible sleeve for receiving and surrounding the pad, plus a set of straps for holding the pad or pad/sleeve combination on the body area that is to be treated. Also, the preferred heating wrap includes a thin sheet that will absorb water, which sheet may be dampened with water and inserted between the heating pad and surrounding flexible sleeve, for providing moist heat treatment.
