Abstract: A system for measuring a current intensity of a current flowing through an electrical conductor (10), where the system includes a first component (1), which has the electrical conductor (10), and a second component (2), which is separate from the first component (1) and has an evaluation device (23), and a magnetic field-sensitive sensor element (3) and a connection line (4). The connection line (4) is a light guide. The sensor element (3) is non-releasably connected to the first end of the connection line (4) and/or to the first component (1). In the operating state, the two components 1(, 2) are DC-isolated from one another and are releasably connected to one another by means of the connection line (4) by way of a light-guiding connection, where the power supply to the magnetic field-sensitive sensor element (3) by the second component (2) and/or transmission of sensor data from the magnetic field-sensitive sensor element (3) to the evaluation device (23) is ensured by the light-guiding connection.

Abstract: An article of clothing, in particular a jacket, comprising a plurality of cut parts each cut to size from a fabric and sewn together, the article of clothing including electronic components. As electronic components, the article of clothing comprises at least one sensor unit for detecting a presence of an external object, a control unit 4, and an electronic signal generator unit, wherein the control unit is designed to receive measured values from the sensor unit during an operating phase of the article of clothing and to transmit control signals generated as a function of the read measured values to the signal generator unit, the signal generator unit being designed to output a predefined signal which can be perceived by a wearer of the article of clothing and/or by an external observer of the article of clothing on receipt of a predefined control signal.
