Abstract: Disclosed is a method for in vitro culture under laminar flow, including the steps of: providing a flow chamber, loading a tissue sample onto a first loading position in the flow chamber, culturing the tissue sample under a laminar cell culture medium flow in the flow chamber, wherein a part of the tissue sample becomes necrotic, and harvesting at least a portion of the tissue sample after the culturing by separating the portion from necrotic tissue. Also disclosed is a flow chamber for in vitro culture under laminar flow according to this method. The flow chamber including a first loading position for a tissue sample and preferably a second loading position for a cell sample.

Abstract: The invention relates to a molding tool (1, 51) for the extrusion of cellulosic molded bodies (4) from a spinning dope (2), having an entry side (6, 56) and an exit side (7, 57) for the spinning dope (2), with at least one nozzle body (8, 58a, 58b, 58c) including a planar carrier (9, 59a, 59b, 59c) with extrusion openings (10, 60) that penetrate the carrier from the entry side (6, 56) to the exit side (7, 57) and have a mouth diameter (12, 62) at the exit side (7, 57) and through which the spinning dope (2) is extruded into the cellulosic molded bodies (4).

Abstract: A method for locating an animal using radio waves. In radiolocation, a large number of possible calculation results for the location of the animal arise. Using the results of previous measurements and calculations with regard to the possible locations of the node to be located, stochastic calculations are used to filter out, from the plurality of the current location calculation results, that result which in fact applies with the highest probability. Acceleration values which are measured at the animal are used in the stochastic calculations. It is assumed that with increasing measured acceleration values the probability increases that there can also be relatively large distances between temporally successive locations of the node to be located.

Abstract: A connection head for a filter cartridge, which is easy and safe to handle. The connection head comprises a housing that has an inlet and an outlet, wherein said inlet and outlet have a port to which a detachable adapter piece for water conduit can be mounted. The adapter piece is attachable by a quick-release fastener. The quick-release fastener comprises a locking element, which locks the adapter piece by being rotated by about less than 90°.

Abstract: A method for determining the state of access control devices and sales or payment machines of an access control system by detecting sound profiles emitted during operation by a component or component group by at least one microphone. Based upon the recorded sound profile, an acoustic identification signature is created in a server or a central computer, which identification signature is based on the frequency spectrum of the recorded sound profile and/or the temporal change thereof. The acoustic identification signature is compared with a reference identification signature(s) stored in the server and assigned to a component or a component group. In the event of the detecting an acoustic identification signature which exceeds a predetermined first threshold value, increased wear of the component or the component group is detected, while if the deviation exceeds a second threshold value, a defect of the component or the component group is defected.

Abstract: A method is described for detecting a rotating wheel of a vehicle that is travelling on a roadway in a travel direction, the wheels of which are at least partially exposed laterally, the method comprising: emitting an electromagnetic measurement beam having a known temporal progression of its frequency onto a first section above the roadway in a direction in a slant with respect to the vertical and normally or at a slant with respect to the travel direction; receiving a reflected measurement beam and recording the temporal progression of its frequencies, relative to the known progression, as a reception frequency mixture progression; and detecting a frequency band, which is continuously inclining or declining over a period of time, in the reception frequency mixture progression as a wheel. A device for conducting the method is also described.

Abstract: The invention relates to a method for increasing the location accuracy for unsynchronized radio subscribers, in which phase evaluation is used to ascertain the position of a transmitter which is to be located. The transmitter to be located and a further transmitter, whose location is known, respectively send a sequence of N signals to at least two receivers, wherein the transmission channel to be used for transmitting a signal is varied, in line with the invention, on the basis of a prescribed, symmetrical hopping scheme. The advantageous characteristics of the hopping scheme and the additional application of the TDOA (time difference of arrival) principle mean that highly accurate location is possible.
