摘要:
The invention relates to a bus system for transmitting data between data processing units (20) in a network, by means of a bus (14) that consists of two signal lines. The signals at said bus (14) are analog signals which lie within a plurality of non-overlapping frequency bands assigned to the individual data processing units (20), and these data processing units (20) use a digital communication protocol to communicate with a signal processor unit (24) that comprises a polyphase filter bank, a D/A Converter (26) and a bus-coupling unit (30) being connected downstream of said bank in order to couple the data signal into the bus (14) in a galvanically-isolated manner. The proposed bus system has a simple design with regard to cabling, allows the use of a Standard communication protocol such as Ethernet for the data processing units (20), and additionally allows data to be transmitted between all network subscribers simultaneously and without restriction.

The invention relates to a self-cleaning self-regenerating surface structure and/or a self-cleaning self-regenerating coating. For improving the cleaning function, the invention proposes a self-regenerating surface structure, especially coating, comprising biocatalytic and/or anti-icing molecules on an exposed surface of said surface structure, especially coating, and biocatalytic and/or anti-icing molecules embedded or contained in said surface structure, especially coating. Further, the invention relates to an object provided with such surface structure or coating and a method for producing the same.

The invention discloses a method for detecting at least one antigen, comprising the following steps: providing magnetic beads, which are coated with antibodies specific for at least one antigen to be detected; bringing the magnetic beads in contact with a washing buffer that comprises at least 8% BSA and incubating the mixture with a sample; isolating the magnetic beads by means of a magnetic separator; and detecting the antigens bound to the magnetic beads by the antibodies. Washing buffers, primers, kits and devices that can be used for said method are also disclosed.

摘要:
In an electrophoresis device with numerous separation channels S loadable with samples, samples are loaded by applying samples in a shared injection channel I intersecting the separation channels S near a point where the injection channel I crosses one of the separation channels S. During exposure to a voltage in the injection channel, the samples are transferred to the separation channels S, and there electrophoretically separated.

The present invention provides for devices and methods for the transmission of data over nodes of a specific network. A device may comprise at least two network nodes, a bus having a transmitting line and a receiving line for interconnecting the network nodes. The respective network node has a fault protection circuit which is to bypass the network node in the event of a fault and is capable of reversing the polarity of the transmitting line and of the receiving line, a detection means for detecting a reverse in polarity of the transmitting line and of the receiving line by the respective upstream network node, and a fault-locating means for locating a fault in the upstream network node when a reverse in polarity of the transmitting line and of the receiving line has been detected.
摘要:
An apparatus and a method for automatic detection of particles, in particular, biological particles such as micro-organisms. The apparatus has a device for binding the particles to separating particles which can be bound selectively to the particles. The apparatus further includes a separating device for extraction of the separating particles with bound particles from a collecting fluid, and a detection unit for detecting a number and/or concentration of the particles separated in this manner. The device for binding the particles to the separating particles includes a collecting device for collecting a collecting fluid including the separating particles and the particles that are provided by a particle-fluid mixture.
