Abstract: A device and a process detect a leak during artificial ventilation of a patient. A measurement system with a sensor arrangement and a sensor fluid guide unit is monitored. A fluid connection is established between a patient-side coupling unit and a medical device with a patient fluid guide unit. A gas sample is branched off from the patient fluid guide unit and guided through the sensor fluid guide unit to the sensor arrangement. A thermal conductivity time course of the gas sample reaching the sensor arrangement is determined with sensor arrangement measured values. Depending on a temporal change in the determined thermal conductivity, a decision is made as to whether there is an indication of a leak between the patient's fluid-guiding unit and the sensor arrangement. The leak establishes a fluid connection between the sensor fluid guide unit and/or the sensor arrangement and the environment.

Abstract: A method for tuning a radio transponder having an antenna, a transceiver unit and a resonant circuit connected to the antenna, wherein the resonant circuit includes a plurality of capacitors arranged in parallel, where each capacitor is arranged in series with a fuse, where a capacitor is switchable via a fuse arranged in series to tune the resonant circuit, and where a control unit associated with the resonant circuit is configured to produce a switching signal for a respective fuse of the resonant circuit based on a control signal transmitted by a radio transponder reader.

Abstract: An apparatus and method for automatic presence monitoring in a passenger compartment, wherein the apparatus includes at least a first user medium that has a first transceiver unit and at least one detector module that has a second transceiver unit, where at least a first sensor and a second sensor are arranged on the at least first user medium, the first and second sensors having different operating principles and being configured to be mutually redundant in order to provide advantageous design conditions such that a presence of at least the first user medium in the passenger compartment is thereby detected with great reliability.

Abstract: A sensing element for a measurement system suitable for dielectric impedance spectroscopy, wherein the sensing element, at least in one operating state of the sensing element, includes at least a first one microstrip conductor, which has a first conductor strip for a measurement signal, a first dielectric substrate and a first ground surface, where the first conductor strip may be applied from the outside and over an area to a container containing a dielectric material sample to be measured.

Abstract: The invention relates to the tuning of a radio transponder having an antenna, a transceiver unit and a resonant circuit connected to the antenna. The resonant circuit comprises a plurality of capacitors arranged in parallel, each capacitor being arranged in series with a fuse. In this arrangement, a capacitor is switchable by means of a fuse arranged in series for the purpose of tuning the resonant circuit. A control unit associated with the resonant circuit is designed and set up to produce a switching signal for a respective fuse of the resonant circuit on the basis of a control signal transmitted by a radio transponder reader.

Abstract: A method of preparing potato fibres includes the steps of: a) washing potatoes; b) optionally removing solid impurities and rinsing water adhering to the potatoes; c) grinding the potatoes into a pulp; d) separating potato fruit water; e) removing starch and optionally residual potato fruit water in order to obtain raw fibres; f) refining the raw fibres; g) mixing in potato fibres which have previously been dried; and h) drying the fibres; as well as potato fibres obtainable by that method and use thereof.
