ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a novel way to use twelve button telephone keypad labeling arrangement for alphanumeric data entry. This invention also relates to a method of alphanumeric data entry using short duration or long duration binary key actuations using a simultaneous coding system and/or sequential coding system for communicating on a standard twelve key push-button telephone keypad. Two binary keys are used for an all capital letter mode or two binary keys for a lower-case letter mode, along with three binary keys for an upper-case letter mode, for producing full alphanumeric text, including punctuation, symbols and control. This TTY/TDD replacement computer terminal invention would be properly classified in the U.S. Patent classification system under:

DESCRIPTION OF PRIOR ART
The twelve button touch-tone telephone keypad arrangement and twelve pairs of tones produced by independently depressing any one of the twelve buttons have become the standard throughout the world. Since the advent of the twelve key push-button telephone arrangement, many have tried to produce alphanumeric text and control means using only twelve buttons. In the telephony industry, the twelve binary key (four high/three wide) push-button telephone keypad arrangement with twenty-four letters of the alphabet, excluding the “Q” and “Z”, arranged in groups of threes, located on the faces of the keys numbered two “2” through nine “9”, or the twenty-six letters of an alphabet arranged in groups of threes, located on the faces of the keys numbered one “1” through nine “9” has become the world standard. The actuation of any one of the twelve binary keys, produces an analog, dual tone multifrequency signal (DTMF), which is a combination of two analog voice frequency tones. The telephone system hardware then converts the analog DTMF tones into a digital signal for processing, digital phones being the exception. In the past, the “Q” and “Z” have been located on the face of the keys in a few different locations. The most common way in the past, is where the “Q” and “Z” are located on the “1” key. Usually the “Q” and “Z” are located next to each other above the “1”.
U.S. Pat. No. 3,675,513 to James Flanagan, et al. discloses a communication system for exchanging alphanumeric information. Flanagan positions from left to right; The “Q”, “Z” and period “.” on the “1” key. The “Q” is produced by actuating the “1” key, followed by the actuation of the “0” key. The “Z” is produced by actuating the “1” key twice, followed by the actuation of the “0” key. The period “.” is produced by actuating the “1” key three times, followed by the actuation of the “0” key.
U.S. Pat. No. 4,012,599 to Jerome Meyer discloses a communicator and encoding scheme. Meyer positions from left to right; The period “.”, “Q” and “Z” on the “1” key. The period “.” is produced by actuating the “*” key, followed by the actuation of the “1” key. The “Q” is produced by actuating the “0” key, followed by the actuation of the “1” key. The “Z” is produced by actuating the “#” key, followed by the actuation of the “1” key.
U.S. Pat. No. 4,427,848 to Peter Tsakanikas discloses an alphanumeric data transmission system. Tsakanikas positions from left to right; the “Q”, “Z” and hyphen “-” on the “1” key, although there is no coding scheme to layout to figure out actuation combinations for data representation. Single actuation is used for the left data position, double actuation is used for the middle data position and triple actuation is used for the right data position to produce the desired alphabetic data.
U.S. Pat. No. 4,440,977 to John Pao, et al. discloses a sequential twelve key apparatus. Pao positions from left to right; the period “.”, “Q” and “Z” on the “1” key. The period “.” is produced by actuating the “1” key, followed by the actuation of the “*” key. The “Q” is produced by actuating the “1” key, followed by the actuation of the “0” key. The “Z” is produced by actuating the “1” key, followed by the actuation of the “#” key.
U.S. Pat. No. 4,532,378 to Yasunoba Nakayama, et al. discloses a telephone apparatus for alphanumeric data entry. Nakayama positions from left to right; the “Q”, “Z” and period “.”. on the “1” key. Single key actuation for the left data position, double actuation for the middle data position and triple actuation for the right data position, followed by the actuation of the “0” key,
