Abstract: In a pattern recognition system, a pattern which is to be recognized later is prescribed in a learning phase. This pattern is detected sequentially, that is to say the informative areas of the pattern are detected and, moreover, the spatial relationship between the areas is also stored. In the recognition phase, a hypothesis which indicates a presumed pattern and, furthermore, indicates where such further prominent areas should be located in the pattern to be recognized if the presumption is correct, is generated on the basis of the acquired data of a first area of a pattern to be recognized, and on the basis of the stored data. Thus, patterns are learned through their location information, on the one hand, and through their spatial relationship to each other, on the other hand, stored and then re-recognized.

Abstract: The invention provides for the automatic control of features, especially of a call diversion feature, of a communications system according to the position (POS) of a mobile terminal (ME). The mobile terminal (ME) can be treated to a certain extent as an indicator of the position of a user carrying said mobile terminal (ME) with him/her. The position (POS) of the mobile terminal (ME) is determined by means of a global positioning system (GPS) of the mobile terminal (ME) and is compared with a stored reference position (RPOS). One or more features of the communications system are then controlled according to the results of this comparison.

Abstract: The invention relates to a method for regulating the transmission power of a transmitter (BS) in a radio system, for a transmission of data (D) to a receiver (MS) by means of a radio interface. The receiver (MS) determines an actual value (PR) for a qualitative parameter of the received signal, makes a comparison with a set value (Psoll) and, thereafter, transmits comparison information (TPC) on the result of the comparison to the transmitter. Adjustment of the transmission power (PT) of the transmitter (BS) is made based on a correction value for the set value (Psoll) of the qualitative parameter of the received signal, in addition to comparison information (TPC) from the receiver (MS).

Abstract: In order to evaluate a radio signal in a radio receiver, comprising an antenna device with several antennae elements (A1, . . . , AM), each of which delivers a received signal (U1, . . . , UM), a number N of first weighting vectors w(k,1), w(k,2), which represent a selection of the eigen vectors for the time-determined spatial covariant matrix, for a user station (MSk) are determined. The symbols contained in the user signal Ik, obtained by the formation of a product of the form SWU are assessed. W is the M×N matrix for the first weighting vectors, S is a selection vector with N components and U is the vector for the received signals (U1, . . . , UM). The selection vector is cyclically fixed in the working phase. A device for the evaluation of a radio signal, comprises, amongst others, a memory element (10) for the storage of N weighting vectors for each one same sender (MSk) and a beam formation network (1) with a control input of the selection vector (S).

Abstract: A synchronization method for a redundant automation system composed of at least two subsystems is provided, where these subsystems execute functionally identical sequences of machine instructions, said sequences of functionally identical machine instructions having increment instructions at corresponding locations for incrementing a synchronization counter. Synchronization is performed on the basis of the value of a synchronization counter at least when one subsystem registers a special event. To do so, a synchronization counter target value is determined so that the subsystems interrupt the execution of the sequence of machine instructions on attaining a synchronization position at which the values of the respective synchronization counters attain the synchronization counter target value.

According to one aspect of the present invention, a method for reducing outdiffusion within an integrated circuit includes forming a gate oxide layer over a substrate, and further forming a silicon plug over a portion of the gate oxide layer. A silicon dioxide layer is then formed over the gate oxide layer, and is arranged around the silicon plug. A first barrier film is formed over the silicon plug, and a dielectric layer is formed over the silicon dioxide layer. In one embodiment, forming the first barrier film includes forming a first oxide layer over the silicon plug, nitridizing the first oxide layer, and etching the nitridized first oxide layer.

Abstract: A once-through steam generator includes a gas flue formed of steam generator tubes welded to one another in a gas-tight manner through fins. The steam generator tubes are connected in parallel for the throughflow of a flow medium, they have a surface structure on their inside for generating a high flow turbulence in the medium flowing through them and they are disposed approximately in a spiral coil in a firing region of the gas flue. The steam generator tubes are constructed in such a way that, when they are in operation, the geodetic pressure loss of the medium flowing through them is at least 0.5 times their pressure loss due to friction. This ensures that such a once-through steam generator can also be operated in low load states of, for example, about 20% of the design load, without excessive thermal stresses occurring.

The temperature is determined recursively as a spatially and time-dependent function of the catalytic converter from the operational parameters of the exhaust gas and structural parameters of the catalytic converter. Catalytic activity in the catalytic converter is determined from the derived temperature and the reagent is metered as a function of the catalytic activity.
