  • Processes, apparatuses and system for measuring a measured variable
    Patent number: 11921070
    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.

  • SYSTEM AND METHOD FOR THREE-DIMENSIONALLY REPRESENTING A HAIRCUT, AND ELEMENT FOR SYMBOLICALLY REPRESENTING A HAIR LENGTH
    Publication number: 20100169055
    Abstract: The invention relates to a system for three-dimensional representation of a haircut including a model head (1), and a plurality of elements (2, 2a, 2b, 2a?, 2b?) variable in length for symbolic representation of hair lengths. The invention also relates to a corresponding method as well as an element for symbolic representation of a hair length.
