Between the switching protection device and method for increasing operational reliability

摘要

For increasing operational reliability in the case of computer-assisted systems (2) with locally connected peripheral input devices (3), on the one hand a between the computer-aided system (2) and at least a single one of the local peripheral input devices (3) in an unauthorized physically unremovable from the computer-aided system (2) switchable between switching protection device (1) is proposed, which is provided internally with a filter mechanism for an autonomous rule-based filtering of the inputs of the connected peripheral input devices (3). It is used for the same purpose, on the other hand, a method is proposed in which, by means of a between the computer-aided system (2) and at least one single locally connected peripheral input device (3) physically difficulty kbar and prepared in an unauthorized unremovable switched between switching protection device (1) a rule-based, self-sufficiently operating filtering of the by the locally connected input devices (3) is carried out, produced inputs.
