The invention relates to a pressurized gas container, having an internal volume for storing gas under pressure comprising a valve for distributing fluid, a pressure sensor for measuring the pressure of the gas and delivering at least one measurement signal, a microprocessor for processing the measurement signal delivered by the pressure sensor and a digital display. The microprocessor converts the measurement signal delivered by the pressure sensor into a measured pressure value, and compares the measured pressure value with at least one preset threshold-pressure value. The digital display displays at least one predefined term reflecting the amount of gas in the container, which is dependent on the comparison performed by the microprocessor.

The monitoring of a technical system using sensor data. In the event of the failure of a sensor, in this case, for the failed sensor, virtual sensor data are created on the basis of the remaining functional sensors. In this case, the sensors for the calculation of the virtual sensor data are selected in two stages. In a first step, firstly, possible candidates of sensors are ascertained on the basis of a knowledge-based approach and the topology of the system. A second step involves calculating a mathematical relationship between the sensor data of a faulty sensor and the possible candidates of sensors for the calculation of the virtual sensor data. Those sensors which form a suitable basis for the calculation of the virtual sensor data can be identified in this way.

A device may receive sensing data that is produced by an environment associated with a fiber optic cable. Based on the sensing data, the device may determine a sensing profile, which indicates a measure of vibration as a function of distance along the fiber optic cable and as a function of time. The device may receive new sensing data produced by the environment. The device may determine that the new sensing data satisfies a vibration deviation criteria, relative to the sensing profile, for a duration threshold. By satisfying the vibration deviation criteria for the duration threshold, the new sensing data may indicate that the environment includes an activity associated with an increased likelihood of damage to the fiber optic cable relative to the sensing data. The device may perform one or more actions based on the new sensing data satisfying the vibration deviation criteria for the duration threshold.
