Abstract: The invention relates to a method and device for fiber optic temperature measurement. The invention also relates to a multimode quartz glass fiber with nanocomposite (NK) containing a polymer and quantum dots (QDs) and its manufacture. These are based on temperature-dependent emission of quantum dots on the surface of optical fibers.

Abstract: A method for operating a digital assistant of a vehicle includes receiving a command to change an operating mode of the digital assistant from a first mode to a second mode using the digital assistant. The method further includes changing the operating mode in response to the received command, and identifying first, vehicle-specific context information for the second mode. The method also includes providing a message having an operator prompt to a user depending on the first, vehicle-specific context information identified by the digital assistant, and receiving user input in response to the operator prompt. The method also includes executing an operation corresponding to the user input at least in part using the digital assistant depending on the first, vehicle-specific context information in the second operating mode. A second message is provided to the user depending on the first user input and the first, vehicle-specific context information.
