The electronic device includes a device housing, an emitter, a receiver, and a reflection structure. The polymerization is catalyzed with a mixture of double metal cyanide catalyst complex and certain magnesium, group 3-group 15 metal or lanthanide series metal compounds. In a second operation state, the refresh control apparatus turns off the power supply to at least one circuit block using the power switching circuit. A second radiation reflector is designed in the form of a second hollow mirror for the reflection of a second part of the ray beam emitted from the laser source as a reference beam into a reference gas cuvette containing the reference gas sample for the gas to be measured. Generally, such a reduction can be achieved by combining a first binder that has a high glass transition temperature and a second binder that has a low glass transition temperature with conventional joint compound compositions.
