| 1 | Illuminated keyboard with illuminated patterns displayed on top surface of keyboard | US11049170 | 2005-02-03 | US07214897B2 | 2007-05-08 | Cheng Hua Chuang |
| An illuminated keyboard with illuminated figures being formed on the top surface of the keyboard including: a top cover, a bottom cover, a plurality of keys and an electroluminescent board. The top cover accommodates the keys and is combined with the bottom cover. The electroluminescent board is installed between the top cover and the bottom cover. The electroluminescent board includes at least one figured pattern to be displayed on a top surface of the keyboard on the top cover when the electroluminescent board is electrified to give light. | ||||||

| 3 | Adjustable ergonomic keyboard for use with stationary palm and elements thereof | US10169654 | 2001-01-03 | US07324019B2 | 2008-01-29 | David J. Levenson |
| An ergonomic keyboard as shown in FIG. 3A for use with a stationary palm wherein the keys (15) of the keyboard are actuated only by motion of the joints in the digits. The keyboard may have a thumb region (20), a palm rest region (8) and a hypothenar rest region which are discrete parts and are adjustable relative to one another along a longitudinal axis. Some keys may be actuated by the back surface of the digits. The keyboard may be on an upper portion (2) which is mounted on a base (1) such that three dimensional rotational adjustment is possible between the upper portion and base. The position of the keyboard relative to a user may be adjusted. The spacing of the keys on the keyboard may be spaced at different intervals and have different forces for actuation. | ||||||
