Abstract: It is an object of the invention to improve processes, apparatuses and systems for measuring a measured variable. To this end, a measured variable is measured in a measuring process on the basis of an NV center as a quantum sensor. The NV center has a plurality of quantum states and is optically excitable on the basis of an occupancy of one of the quantum states into at least one excited state of the quantum states by means of an excitation light. The at least one excited state can decay at least with emission of emission light of the NV center. In the measuring process, the NV center is irradiated by the excitation light, the excitation light having a time periodic modulation, and a respective occupancy probability and/or a respective lifetime of the quantum states depending on the measured variable and the excitation light.

Abstract: A circuit housing having a printed circuit board and a circuit and holes in which peg-like positioning elements projecting away from the housing engage for positioning the PCB relative to the housing, at least one positioning element projecting without play into one circular hole, another positioning element, accommodated in another hole, having spreading fingers separated from one another by at least one recess, projecting into/through the further hole, elastically transverse to the direction of an imaginary connecting line of the holes and a cross-section such that a) in the direction of the imaginary connecting line, there is play between the spreading fingers and a radially inner circumferential surface of the another hole on both sides, but b) the spreading fingers make contact by their diametrically opposite side faces with the inner face of the another hole perpendicular to the connecting line without play only along a contact line/point.
