The base station includes a second wireless data interface which receives the sensor data transmitted by the first wireless data interface at arbitrary times, a first data storage which stores the sensor data received by the second wireless data interface, and at least one readout data interface which transmits the sensor data stored in the first data storage to an external readout device.

A data management apparatus (20) includes a data acquisition unit (210), a municipality information generation unit (220), and a storage processing unit (230). The data acquisition unit (210) acquires data generated by a sensor apparatus installed along a road in association with sensor identification information capable of identifying the sensor apparatus. The municipality information generation unit (220) generates, by using the sensor identification information, municipality information indicating a municipality that manages a location where the sensor apparatus is installed. The storage processing unit (230) stores the data acquired by the data acquisition unit (210) in a data storage unit (232) in association with the municipality information generated by the municipality information generation unit (220).

A data processing apparatus is provided comprising a data acquisition unit configured to acquire sensor data of a sensor that is capable of measuring physical quantities of a measurement target, an interpretation unit configured to attempt to interpret, in accordance with a definition for each field of the sensor data, sensor data in the respective fields, and an output unit configured to output the sensor data interpreted by the interpretation unit for a field of which a definition is known, and to output the sensor data acquired by the data acquisition unit as is for a field of which a definition is unknown along with an indicator indicating unidentified. The data processing apparatus further comprises a confirming unit configured to later confirm a definition for at least one field among fields of which the definition is unknown.

An autonomous device for measuring at least one characteristic of a fluid circulating in a conduit in a flow direction comprises a permanent magnetic field source, a magneto-electric converter and a processing circuit capable of using the electric charges supplied by the converter to supply a measurement of a characteristic of its environment. The source and the converter are placed in a stator and a rotor forming the device. The autonomous device further comprises attachment means allowing the stator to be fixedly placed in the conduit or at one end of the conduit, in a configuration in which the axis of rotation of the rotor is parallel to the flow direction. A control system may employ at least one such autonomous device.

The test lab set-up includes a test flow bench for mounting one or more test devices, an adjustable nozzle for simulating urine flow, and a sensor for collecting data associated with the simulated urine flowing through the test device(s). A computing device for measuring and/or calculating various parameters associated with the simulated urine flow may also be included. The test device may have a shape corresponding to a handheld uroflowmeter subject to testing. The angle of the adjustable nozzle may be adjusted to test for various angles of urine flow. Similarly, the angle, pitch, and roll of the test device may be adjusted to test for various angles at which a uroflowmeter is held. As fluid flows through the test device, the sensor collects information such as, for example, flow rate, duration, volume, and the like. The sensor transmits the data collected to a computing device for additional processing.
