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.

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

A device for the wire-free determination of a position of a mechanical force-transmitting device, having at least one storage device for storing electrical energy, at least one sensor element which detects the position and is monitored by at least one sensor electronic unit, including at least one radio transmitter, and at least one photovoltaic energy supply device supplying the storage device with electrical energy.

A heating control system, monitoring system and predictive maintenance radio sensor system. The heating control system comprises at least one temperature transducer element having a downstream voltage transformer; an energy storage device which is electrically coupled to the at least one voltage transformer; a logic assembly coupled to the energy storage device and having sequence control; a data transmission unit coupled to the logic assembly; and a sensor, coupled to the logic assembly, for measuring ambient parameters.

Heating control system

An energy-autonomous sensor for detection of physical environmental parameters, having at least one sensor element, one storage element and one control circuit, with a timer circuit which is activated on reaching a predetermined electrical voltage on the storage element, activates the sensor and the control circuit at predetermined time intervals, and deactivates them after a predetermined operating time, such that this results in a time duration of sensor operation and a sensor operation pause.

A sensor system has a least one voltage generator for conversion of non-electrical energy to electrical energy. At least one energy store is connected downstream from the voltage generator. At least one voltage converter is connected to the energy store such that its output signal is suitable for operation of a processor controller. At least one sensor is provided, and at least one transmitter enables wire-free transmission of transmission messages produced by the processor controller and containing at least one measured value from the at least one sensor. A timer circuit is triggered as a function of a voltage level of the at least one energy store, and activates the sensor system to transmit at least one transmission message after a specific time interval.

The transmitter which can be fed thermally has at least one heat transducer element () with a downstream voltage transformer () and logic assembly () as well as a data transmission unit (), and is characterized in that the logic assembly () is designed on a ULP basis, and the data transmission unit () transmits a broadband signal.

Thermally feedable transmitter and sensor system

A sensor system (S, S') having a least one voltage generator () for conversion of non-electrical energy to electrical energy. At least one energy store () is connected downstream from the voltage generator (). At least one voltage converter () is connected to the energy store () such that its output signal is suitable for operation of a processor controller (). At least one sensor () is provided, and at least one transmitter () enables wire-free transmission of transmission messages which can be produced by the processor controller () and which contain at least one measured value from the at least one sensor (). A timer circuit () is provided, which can be triggered as a function of a voltage level of the at least one energy store (), and which activates the sensor system (S) in order to transmit at least one transmission message after a specific time interval.

A coding scheme is specified which, compared to the prior art and with the system having a structure resolution of the same magnitude, allows an enlarged code size for the same number of code elements, and/or by which fewer code elements are required per code for a predetermined code size. The code elements are disposed with basic values in a matrix defined in a novel manner, with the matrix having a finer subdivision of the basic values than the subdivision corresponding to the structure resolution. Further development with mean-value formations are possible.

An encapsulated installation, in particular a switching installation for high or medium voltage, includes a plurality of sensors located in an interior of an encapsulation. A central monitoring device is provided for information interchange with the surface acoustic wave sensors. An antenna element of the monitoring device is disposed at the encapsulation and is directed towards the interior. The sensors can be interrogated selectively.

Encapsulated installation

An encapsulated tubular conductor having at least two antenna elements disposed on the capsule thereof for maintaining therebetween wireless information transmission in a transmitting-receiving direction, and a transmitting-receiving device located outside the capsule and assigned to one of the antenna elements includes another transmitting/receiving device also disposed outside the capsule and assigned to the other of the antenna elements, the antenna elements being directed towards an interior space of the capsule, the interior space serving as a transfer path via which information is transferable between the transmitting-receiving devices.

Encapsulated tubular conductor

A method for detecting the position of a switching device and an encapsulated switching installation having at least one switching device. A transmitted signal is emitted into the interior of an encapsulation to make it possible to easily detect the position of a switching device in an encapsulated switching installation. A resultant reflection signal is received and stored. After a repetition of this process, the two received reflection signals are compared with one another. In the event of any discrepancy, a message signal is produced for the new switching state.
