Abstract: In a method for operating a communication system having a plurality of nodes which have access to a shared channel, a transmission process for transmitting a message via the channel is monitored for bit errors, and when a bit error occurs, a signaling message is transmitted via the channel in order to signal the bit error. In order to allow communications processes between the nodes to be controlled as a function of a bit error rate of the channel, a signaling rate of the signaling messages is measured and a bit error rate of the channel is determined as a function of the signaling rate.

Abstract: A data processing device and a method for error detection and error correction. The data processing device includes an error detection arrangement and an error correction arrangement. The error detection arrangement is able to detect correctable error and uncorrectable error in the data stored in a memory cell of the memory. The error detection arrangement then determines the neighboring memory cells or memory cells that are physically adjacent to the memory cell for which the correctable error was detected and generates a signal indicating a fault depending on the correctable errors detected in the neighboring physically adjacent memory cells. If a signal indicating a fault is not generated, then an error correction arrangement is used to correct the correctable error detected by the error detection arrangement.

Abstract: A nuclear magnetic resonance (NMR) spectroscopy probe has a sample cell into and out of which a room temperature liquid sample may be directed. The cell is surrounded by a radio frequency coil that is used to perform NMR measurements of the liquid sample, and which is maintained at cryogenic temperatures. The coil is separated from the sample cell by a thermally insulative boundary, such as a vacuum. The sample may enter the cell through an input path, and may exit through an output path. The input path, output path and sample cell may be surrounded by a sheath through which flows room temperature gas. The ends of the sample cell may be tapered to promote thorough flow through the cell, and flow diverters may be included in the sample cell adjacent to the input and output paths to force flow to the outer wall of the sample cell.

In accordance with the invention a rapid and homogeneous mixing-together of the two reaction liquids is achieved in milliseconds.
