| abstract |
ALPHANUMERIC KEYPAD FOR DATA ENTRY ABSTRACT OF THE INVENTION The data entry system includes a keypad having twelve data entry keys and three shift keys. In the first mode of the data entry system numeric characters are entered by a single keystroke. The other modes are activated by a combination of sequential keystrokes of a respective function key and a data key. The shift keys are color coded with respect to the alpha characters entered by a particular key. The keypad is in bus communication with a keypad driver which in turn is in bus communication with a microprocessor. |
