Abstract: An apparatus for locally recognizing an instruction of a given set of instructions. The apparatus includes an acoustic sensor configured to convert acoustic signals into electric signals and includes an electronic circuit configured to switch from a first state to a second state based on first acoustic signals that are converted into electric signals and configured to ignore second acoustic signals that are converted into electric signals when the electronic circuit is in the first state and to assign the second acoustic signals to the instruction when the electronic circuit is in the second state.
