Abstract: A nebulizer is proposed which receives a container with a fluid and an indicator device. The indicator device stops further use of the container in a locked state when a predetermined number of uses has been reached or exceeded. In the locked state, a locking device locks the nebulizer against rotation in a partially tensioned state and, thus, against further use. After replacement of the container including the indicator device, the nebulizer can be used again.

Abstract: A method for detecting in-vivo properties of a biosensor. In the inventive method, a sensitivity-to-admittance relation is provided and a raw current in the biosensor is measured. An in-vivo current response is also measured at first and second operating points. A time constant ? is determined by the electrical capacitance C of the working electrode and the electrical resistance RM of the membrane by ?=RM·C. The first and second operating points are selected below and above ?, respectively. An analyte value in a sample of a body fluid is determined by using the raw current and compensating sensitivity drift in the biosensor, which in turn is compensated by using the measured value for the raw current and a corrected value for the sensitivity. The failsafe operation of the biosensor is monitored by using the in-vivo current response measured at the first and second operating points.

The invention further concerns a formed body made of a polymer which is doped with a conductive substance, which has at least one contactable area, within which a contact material is applied onto the polymer, which has a lower specific resistance at 23° C. than the polymer.

Abstract: For weaving pattern formation of a woven fabric with weft threads (3), warp threads (1) and effect threads (2), data sets (20) are produced according to a method in which data values are derived from weft sequence numbers (30) and from positions of interlacing points (P) of an effect thread (2) with the weft threads (3) in the pattern repeat (29). These data sets (20) are supplemented by further data values (31, 32, 33, 34) derived from the weaving pattern, in such a manner so that they form a pattern draft (28) for a weaving pattern with additional weft effects. In a weaving machine with devices for slidingly displacing effect threads (2) in the weft direction (12), the weaving pattern formation is derived from the data sets (20) of this pattern draft (28).
