Device for sensing the activity of people or the status of infrastructures or objects influenced by people

An apparatus for detecting the activity of persons or the state of infrastructures or objects influenced by persons,

• wherein the apparatus comprises at least two sensors which are set up to measure different physical quantities,
• wherein one or more or all of the sensors are set up to react to a preset threshold value of the respective measured physical quantity and to trigger at least one of the following actions when the threshold value of the measured physical quantity is exceeded:
• data storage,
• modification of a counter or
• transmission of a data telegram by radio, and
• wherein the apparatus comprises an energy converter for converting a primary energy into electrical energy for operating the apparatus or one or more or all of the sensors, wherein the energy converter is arranged to obtain the primary energy independently of an energy resulting from the respective measured physical quantity,
• wherein the apparatus comprises an energy storage device adapted to store the electrical 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 are arranged to 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.

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.
