A single-hand interdigit-coordinated mobile keyboard input device has a chassis configured to conform to human fingers with a plurality of articulating finger frames connected adjacent to each other, a plurality of user input elements, a processing device, and a signal transmitter. The plurality of user input elements is connected around the chassis in order to capture flexion, extension, adduction, and abduction movements of the plurality of articulating finger frames. The processing device interprets signals received from the plurality of articulating finger frames into desired output communication elements such as text characters. The signal transmitter sends the interpreted output to a computing device.

An electronic pointing device includes a housing. In addition, the electronic device includes a position transducer coupled to the housing. Further, the electronic pointing device includes a plurality of electrical switches coupled to the housing. Still further, the electronic pointing device includes a cover plate removably coupled to the housing. The cover plate includes a plurality of holes, each hole aligned with one of the plurality of electrical switches. The electronic pointing device also includes a plurality of button members. Each button member is removably disposed in one of the holes of the cover plate and disposed to engage the corresponding, aligned electrical switch to actuate that electrical switch.

An X-ray fluoroscopic imaging apparatus includes a table, an imaging system including an X-ray source and a detector, and an operation panel unit including a plurality of operation input units. The plurality of operation input units include an emergency stop unit and a stop state release unit. The emergency stop unit and the stop state release unit are provided separately from each other at different positions.

An apparatus for entering alphabetic data into a computer or other electronic or mechanical devices with a keyboard, wherein the keys are placed in an ordered arrangement. The vowels AEIOU are grouped together and arranged on a left side of the keyboard. The vowels are arranged in alphabetic order vertically across the three rows of keys with letters AE on the top row, the letters IO on the middle row, and the letter U on the bottom row. Each of the vowels has a same color. Consonants are arranged in consonant groups comprised of BCD, FGHJK, LMNPQ, RST, and VWXYZ. The consonant groups are arranged from left to right in alphabetic group order. The consonants in each of the consonant groups are arranged vertically across the three rows of the keys. The key groupings may also be differentiated by color.
