Claim 11:
12. A method for detecting the activity of persons or the state of infrastructures or objects influenced by persons by means of
acceleration measurement or
evaluating at least two different physical quantities, the method comprising:
measurement of
an acceleration by an acceleration sensor of an apparatus or
at least two different physical quantities by at least two different sensors of an apparatus,

reaction of
the acceleration sensor to a preset threshold value of the measured acceleration or
one or more or all of the at least two sensors to a preset threshold value of the respective measured physical quantity,

triggering of at least one of the following actions by
the acceleration sensor or
at least one responsive sensor

when the threshold value is exceeded:
data storage,
modification of a counter or
transmission of a data telegram by radio,, wherein the apparatus comprises an energy converter which converts a primary energy into electrical energy for operating the apparatus or
the acceleration sensor or
the at least two sensors,, wherein
the acceleration sensor or
one or more or all of the at least two sensors, is/are operated via the electrical energy obtained from the primary energy and the energy converter obtains the primary energy independently of an energy resulting from
the measured acceleration or
the respective measured physical quantities,, wherein the apparatus has an energy storage device which stores the electric energy converted from the primary energy via the energy converter, wherein the energy storage device comprises a first energy storage and a second energy storage, wherein the first energy storage has a higher storage capacity than the second energy storage and wherein the second energy storage has a lower internal resistance than the first energy storage, and wherein the first energy storage and the second energy storage store the electrical energy converted from the primary energy via the energy converter,, wherein the first energy storage and the second energy storage are connected via one or more diodes such that electrical energy can be transferred from the first energy storage to the second energy storage, but not from the second energy storage to the first energy storage.
