Signal input control e.g. for computer keyboard, requires all signals from adjacent keys of keyboard not to be passed on as keyboard signals

摘要

A method for controlling the input of signals via a keyboard, including the reception of the successive signals from the depressed keyboard keys, and their further transfer as signals from the keyboard. For all keys, excluding the keys which should function with others (Shift, Ctrl, Alt, Alt Gr, Caps, Lock), after reception of a signal from any key(Depression of key) and up to the end of the signal from this key (release of key) all subsequent signals from the adjacent keys on the keyboard are not passed on as keyboard signals.
