Abstract

The present invention incorporates unique methods and components for data entry and typing using the components including an ergonomic keyboard with substantially and uniformly low-profile key elevation in combination with built-in germicidal, non-germicidal light-emitting diodes (LEDs) and laser lights to disinfect and illuminate surface of the lowly situated key caps and adjacent affected surfaces.

Claims

1. A keyboard comprising:

adjustable, attachable, detachable feet having a first mounting opening configured to receive an edge of the keyboard to hold the keyboard at a first height and a second mounting opening recessed into the feet opposite the first mounting opening and configured to receive the edge of the keyboard and hold the keyboard at a second height as an alternative configuration;

the feet having curved edges;

wherein said first and second mounting openings provide various tilt adjustments to a modular keyboard housing of the keyboard via different configurations of said feet mounted to the modular keyboard housing, said modular keyboard housing is at lowest elevation by having said feet mounted to said modular keyboard housing using the first opening, said modular keyboard housing is at middle elevation by having said feet mounted to said modular keyboard housing using the second opening, and said modular keyboard housing is at highest elevation by having said feet mounted to said modular keyboard housing using the first opening when said feet is flipped vertically, wherein said feet are mounted to the front of said modular keyboard housing to provide negative tilt to an operator'"'"'s hands and wrists, or positive tilt to said hands and wrists as said feet are mounted to the rear of said keyboard housing, and said hands and wrists are in neutral angle as said feet are dismounted from said modular keyboard housing; and

one or more LEDs for transmitting visible, invisible wavelengths, short-wavelength ultraviolet radiation (UV-C), germicidal UV, and non-germicidal lightwaves onto the surface of said key caps/keycaps of the keys of the keyboard and periphery.
