Abstract: In a method for operating a respiratory gas analysis device with at least one gas sensor, once a respiratory gas analysis has been carried out, the gas sensor is heated to a temperature that lies above a predefinable temperature threshold value.

Abstract: A mouthpiece for a device for measuring analytes in exhaled air includes a gas path configured to convey exhaled air to the device and a film arranged so as to block the conveying of the exhaled air through the gas path. A system, in one embodiment, includes the mouthpiece and a device configured to measure analytes in the exhaled air. The mouthpiece is configured to be releasably connected to the device. The device includes a pressure sensor and, in one embodiment, a pump configured to pump air via the mouthpiece when connected to the device. The device is configured to be enabled to measure predefined analytes in the exhaled air when a pressure curve measured via the pressure sensor satisfies one or more predefined conditions.

Abstract: A monitoring device for monitoring inactive behavior of a monitored person in a monitored zone includes a plurality of monitoring sensors configured to record sensor data. The monitoring sensors are positioned in at least two spatially separated monitored subzones of the monitored zone. The monitoring device further includes an evaluation device including a model module and a test module. The model module produces a first inactivity model in a spatially anonymized manner for a first time period with reference to sensor data in the first time period. The model module produces a second inactivity model for a second time period. At least portions of the second time period are formed later than the first time period. The test module compares the first inactivity model and the second inactivity model and provides a change notification if there is a deviation between the first inactivity model and the second inactivity model.

Abstract: An emergency telephone has an emergency call button and is designed to place an emergency call to a target address when and/or after the emergency call button is actuated. The emergency telephone includes a housing that is designed to be opened and closed at least partially without the use of tools and/or in a non-destructive manner. The emergency telephone includes a memory device for storing functions and data and which is designed to be removed and reinstalled in the housing or to be replaced by a different memory device.

Abstract: Keypad devices have become commonplace in everyday life. They are part of our everyday life, in the form of pocket calculators, telephones, remote control devices, and cellular phones. Cleaning these keypad devices is problematic, since they have a large number of actuatable keys, due to the functions to be performed. As a mechanical interface in the keypad device, each key is a critical weak point in terms of maintaining a tight seal. An easy-to-clean keypad device, in particular an emergency call device, has a main body, an electronic assembly—which includes circuit elements and is installed in main body—a closing shell and keys, which are installed in closing shell and are designed to mechanically actuate the circuit elements. Closing shell with installed keys is a first preinstalled assembly, and main body with installed electronic assembly is a second preinstalled assembly. The first and second preinstalled assemblies are interconnected such that they may be separated.
