Beschreibung
Zusammenfassung:	An apparatus for detecting the activity of persons or the state of infrastructures or objects influenced by persons by means of acceleration measurement. The device has an acceleration sensor which is arranged to react to a preset threshold value of a measured acceleration and, when the threshold value is exceeded, to trigger at least one of the actions of data storage, modification of a counter or transmission of a data telegram by radio. The apparatus further comprises an energy converter for converting a primary energy into electrical energy for operating the apparatus or the acceleration sensor. The energy converter is arranged to obtain the primary energy independently of an energy resulting from a measured acceleration.
