A sensor management unit according to an aspect of the present invention includes: a sensing data acquisition portion configured to acquire sensing data obtained by a sensor observing a target; a metadata generating portion configured to generate, for the acquired sensing data, metadata indicating an attribute of the sensor; an identification code generating portion configured to generate a first identification code for identifying the sensing data, and a second identification code for identifying the metadata; and a communicating portion configured to transmit, to an external device, at least one of the sensing data to which the second identification code is added and the metadata to which the first identification code is added.

A wearable article incorporates a sensor device (10) which comprises a sensor module (101) and an input-output interface (105) arranged to send and receive data over a bidirectional line (11). A buffer (103) is arranged to store time-series sensor data. A programmable and erasable non-volatile memory (109) receives and stores an identifier for the sensor device (10). The sensor module (101) generates an inference using the sensor data. The sensor device (10) is arranged to switch between sending, over the bidirectional line (11), data sensed by the sensor module (101) and the generated inference. The sensor device (10) is a single-wire sensor device. The input-output interface (105) is a single-wire input-output interface. The sensor module (101) is a motion, electropotential, electroimpedance, chemical, or optical sensor module. The sensor device (10) is provided in a system comprising a master device.

A radio sensor module having a sensor base module having at least one sensor circuit board that has a sensor, and/or having a terminal for connection to a sensor external to the radio sensor module; a process terminal and/or an extended sensor terminal; a housing portion that accommodates the sensor base module and the sensor circuit board; and a radio sensor unit having a structural carrier that carries therein a radio circuit board and an energy store that supplies the radio circuit board with electrical energy. The energy store has an electrical battery and an electrical condenser which are electrically connected in parallel. A modular system is also provided for forming such a radio sensor module.

A gas meter control system is adapted for use in gas meters having a plurality of different sizes (e.g., ability to measure different flowrates and/or different gas volumes per billing cycle) and different functional capabilities. In an example, the gas meter control system is configured to recognize and identify a metrology unit, sensor(s), switch(es), valve(s), valve motor(s), and/or other device(s) within a gas meter. Having identified devices present within a gas-environment and an air-environment of the meter, the control system selects and executes appropriate software to operate the identified devices. Addition of an additional component to the meter (e.g., an earthquake sensor or a tamper sensor) results in identification of the added component and execution of appropriate control software. Accordingly, the gas meter control system replaces a number of control systems configured to operate a single specific meter and/or configuration.

An apparatus for charging fees to a renter of equipment based upon wear to an item of equipment is disclosed herein.

The invention relates to a sensor module (10) comprising a first submodule (101) comprising an electronic unit (105) for measuring and transmitting movement data, and a first structure (103), and a second submodule (201) comprising a fastening means for fastening the second submodule (201) to a wearer, and a second structure (205), wherein the first structure (103) can form a reversible mechanical connection with the second structure (205), with the result that the first submodule (101) and the second submodule (201) are reversibly connected to one another.

A method monitors a sensor clock signal in a sensor unit, which is generated and output for a data transfer between the sensor unit and a control unit with a predefined period duration. A reference clock signal having a predefined reference period duration is received. The sensor clock signal is compared to the reference clock signal. Based on the comparison, a deviation of the current period duration of the sensor clock signal from a target period duration is detected. Based on the detected deviation, a counting pulse or a reset pulse is emitted.
