Operating device and method for detecting an enabling act

摘要

The device comprises an evaluation unit that evaluates a change in capacitance of the capacitive sensors (1-3) and outputs the temporal output waveforms (11-13). An evaluation unit detects a characteristic time course of the output signals and a release control action of an operator at an input panel. The evaluation unit generates an enable signal based on the control action. A release unit receives the enable signal to validate a subsequent operator action within a predetermined time period. An independent claim is included for a method for operating machine accumulating conductive liquids or pasty materials.
