Abstract
A full range of alphanumeric characters is obtained with two different modes upon a twelve key telephone keypad. Numerics are obtained with single keystrokes in one mode and English alphabetics obtained with single and paired keystrokes in another mode. Memory is provided in which a plurality of telephone numbers can be stored, organized, identified and retrieved by a combination of alphanumeric characters including names and abbreviations. A visual display facilitates storing and retrieval of any telephone number. Alphanumeric messages can be transmitted to, and received from, other remote telephonic devices. Any language is encompassed and use of two languages on one keypad is facilitated. Characters in one language such as English are obtained as above in one mode and characters of another language possessing considerably more characters, e.g. Chinese or Japanese, are obtained in another mode with use of sequential key pairs in which the order of the sequence determines which of two different characters is obtained. Both sets of alphabetic characters are printed upon the keypad. Single and dual keystrokes are differentiated with an interval threshold which can utilize a threshold algorithm for customized interval threshold settings.
