Abstract: An appliance is disclosed for measuring at least one gas analyte in exhaled air. In at least one embodiment, the appliance includes an inlet opening for the introduction of exhaled air (mouthpiece), at least one measuring chamber for receiving a sensor unit, and a conduit which provides a fluid connection from the opening to the measuring chamber, and wherein, depending on the gas analyte that is to be measured, a sensor unit with a suitable gas sensor can be introduced into the receiver.

Abstract: The present embodiments relate to a monitoring system for a medical device, wherein the medical device comprises a robot and an image recording part which can be moved by the robot. Provision is made for a radiation source which is attached to the medical device, and for a radiation receiver which is situated remotely from the medical device and is for receiving radiation that is emitted from the radiation source. A comparison entity compares the point of impact of radiation on the radiation receiver with one or more predetermined points of impact of radiation on the radiation receiver. The invention further relates to a corresponding method for monitoring a medical device.

Abstract: Example embodiments relate to a device for measuring nitrogen monoxide in exhaled air by a gas sensor unit with at least one gas sensor. A device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide may be included. The device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide includes a non-consuming catalyst for catalyzing the oxidation of nitrogen monoxide to nitrogen dioxide.

Abstract: An x-ray system is provided. The x-ray system includes an x-ray emitter which can be adjusted by at least one arm as a first x-ray component and a recording system which can be adjusted independently of the at least one arm. The recording system may be adjusted by at least one additional arm as the further x-ray component. The two arms can be pivotably mounted about a common axis of rotation.
