摘要:
A bus system includes at least two data buses, the first data bus having a first number of users and the second data bus having a second number of users. At least two TTCAN buses, which are interlinked by users connected simultaneously to both TTCAN buses, are used as the data buses. Fewer users than the sum of the number of users of the first TTCAN bus and the number of users of the second TTCAN bus are connected to the two TTCAN buses at the same time. A generating arrangement is included to generate a scalable fault tolerance in the bus system as a function of the number of users connected to the at least two TTCAN buses at the same time.

The invention provides a method of processing protein peptide data obtained from healthy or pathological samples for analysis, comprising the steps of: providing a list of peptide sequences and associated auxiliary information representing an input data set; compiling from the input data set a new peptide sequence list by removing peptide sequence redundancy in the peptide sequence list, said new peptide sequence list representing a peptide data set; and grouping together members of the peptide data set originating from the same protein thus generating a protein data set.

A method and a device for performing switchover operations and for comparing signals in a computer system having at least two processing units, a switchover device being provided, and switchover operations being carried out between at least two operating modes, a comparator being provided, and a first operating mode corresponding to a comparison mode, and a second operating mode corresponding to a performance mode. At least two analog signals of the processing units are compared in such a way that, as a function of these signals, a difference is formed.

The invention relates to a plain bearing composite material comprising a steel carrier layer and a bearing coating which is applied to the carrier layer in such a way that it cannot be removed and consists of lead-free aluminium bearing alloy consisting of between 4.4 and 6 wt. % of zinc, between 2.5 and 6 wt % of bismuth, between 1 and 2 wt. % of silicon, between 0.8 and 1.2 wt. % of copper and between 0.2 and 0.8 wt. % of magnesium, optionally a maximum of 0.2 wt. % each of titanium, nickel, manganese, and tin, optionally a maximum of 0.6 wt. % of iron, and also optionally respectively a maximum of 0.1 wt. % of impurity related additives, the total quantity thereof not amounting to more than 1 wt. % of the sum of the constituents. The aluminium bearing alloy forms an aluminium solid solution supersaturated with zinc, said zinc being finely distributed by solution annealing and subsequent chilling.

A method and a device for exchanging data in messages between at least two stations connected via a bus system, the messages containing the data being transmitted by the stations over the bus system and the messages being controlled over time by a first station in such a manner that the first station repeatedly transmits a reference message over the bus at at least one specifiable time interval and the time interval is divided into time windows of specifiable length, the messages being transmitted in the time windows, a reference message and the subsequent time windows until the next reference message being combined into a first cycle, and the first station interrupting the transmission at the end of a first cycle due to a stop request, in particular, a message of the at least second station.
摘要:
A method, a device, and a bus system for synchronizing at least two buses having at least one bus user, a global time being determined in each bus, and the deviations in the global times of the buses being determined from the global times, the buses being connected via at least one user and the deviations in the individual global times being transmitted to at least one bus user, and the global times of the buses connected via at least one user being adjusted to one another as a function of the deviations in the global times, so that the buses are synchronized with respect to the global times. The buses may include TTCAN buses.

A method for operating a mixed-potential exhaust-gas probe for an internal combustion engine having a heatable probe ceramic 1.3 with a first electrode 1.5, which is arranged in a chamber 1.6 and is subjected to the reference atmosphere and with a second electrode 1.4 which detects gas molecules and is arranged in the exhaust gas of the internal combustion engine, a pump voltage being applied between the first and second electrodes by means of a pump voltage source, so that, in the interior of the chamber 1.6, a somewhat reduced oxygen partial pressure is adjusted by the electrochemical pumping off of the oxygen molecules, characterized in that one applies a constant external voltage to the electrodes (1.4, 1.5) with this voltage deviating from the thermodynamic equilibrium voltage of the wanted reaction, measuring and evaluating the current dropping across the electrodes (1.4, 1.5).

An apparatus for detecting the angular position of a first rotatable body (10, L) has a number n of uniform angle markings or teeth (11), with at least two rotatable gear wheels (12, 13, 14, 15), which respectively have n1, n2, n3, n4 uniform angle markings or teeth. The angle markings of the at least two rotatable gear wheels (12, 13, 14, 15) cooperate with the angle markings (11) of the first rotatable body (10) in such a way that by detecting the angular positions &thgr;, &psgr; of the at least two rotatable gear wheels (12, 13, 14, 15), the angular position a of the first rotatable body can be determined. When there are two of the at least two rotatable gear wheels (12, 13; 12, 14; 12, 15; 13, 14; 13, 15; 14, 15), ¦ni-nj¦>1 and (ni, nj)=1 or ni, nj are relatively prime and when there are more than two of the at least two rotatable gear wheels, (ni, nj)=1, where 1=i
