A micromechanical structure, particularly for an acceleration sensor, includes a substrate, which has an anchoring device, and a centrifugal mass, which is connected to the anchoring device via a flexible spring device, so that the centrifugal mass is elastically deflectable from its rest position. A predicate state associated with a packet of data is to be compared to an instruction associated with the predication criteria. The reflected IR radiation is received by an IR camera as IR receiver. A pawl is pivotally mounted in a transverse groove in the body and includes two toothed sides.
