Abstract: A device for detecting a sensory perception with regard to an analyte, having a sensor system and an organic receptor cell for detecting the sensory perception. The organic receptor cell is designed to assume a cellular state, which depends on the analyte in contact with the receptor cell. The sensor system is designed to determine the cellular state and to output it to the cellular state signal, which indicates the cellular state.

Abstract: A method for monitoring a process consists of repeatedly acquiring at least two different pieces of information of the process, performing a component transformation using the acquired information to calculate a main component measurement vector in a main component space, calculating a process indicator quantity by using the calculated main component measurement vector with one or several main component measurement vectors of a previous acquisition, and detecting a process end by using the process indicator quantity. Apparatus for monitoring a process is also disclosed.

Abstract: The method according to the invention for determining characteristics of a sample liquid including a plurality of substances includes the recording current-voltage measurement data of a liquid with at least one known characteristic, the transforming of measurement data of the liquid into a feature space to obtain a first plurality of feature values, the recording of current-voltage measurement data of the sample liquid, the transforming of measurement data of the sample liquid into the feature space to obtain a second plurality of feature values, and the determining of at least one characteristic of the sample liquid based on the feature values of the sample liquid in relation to the feature values of the liquid with the at least one known characteristic.

Abstract: An apparatus for monitoring a process comprises an acquisition means for repeatedly acquiring at least two different pieces of information of the process. A means for performing a component transformation uses the acquired information to calculate a main component measurement vector in a main component space. An evaluation means calculates a process indicator quantity by using the calculated main component measurement vector with one or several main component measurement vectors of a previous acquisition. Further, the evaluation means is formed to detect a process end by using the process indicator quantity.

Abstract: An encapsulating device having a material encapsulated therein comprises a asic body provided with a recess for receiving therein the material and formed by microsystem technology in such a way that the material is fully arranged within the recess. A diaphragm extends across the basic body and is implemented in microsystem or thin-film technology. The diaphragm is used for encapsulating the material in the recess of the basic body in such a way that the diaphragm extends in spaced relationship with the material. An electrically actuable heating means is provided for destroying the diaphragm so as to expose the material.

Abstract: A description is given of sensors in in the form of field effect transistors and capacitors which are suitable for qualitatively and quantitatively determining species to be analyzed, for example molecules or ions, in liquid or gaseous media. A special field of application is the selective determination of the presence and concentration of gases. The sensors are defined in that they have a sensitive layer consisting of a heteropolysiloxane.
