Abstract: The invention pertains to a building, particularly in the context of a nuclear installation. The building is formed with an outer shell and an inner shell which form an intermediate space therebetween. A sealing element is disposed in the intermediate space. The sealing element is gas tight, it envelopes the inner shell, and it is largely freely movable perpendicularly to the surfaces of the shells defining the intermediate space. Pressure fluctuations, particularly pressure waves, originating on the inside of the building are received and equalized by the sealing element, while the gas-tightness of the sealing element is largely assured.

Abstract: The method is for testing classes of an object oriented program available for the first time.Classes are tested in that the tester interactively inputs test commands with which method calls are possible. The checking of the test results is likewise possible in interactive fashion.The testability is achieved in that the required call parameters are calculated in advance for all methods allowed in the class and in that precautions are undertaken in the computer memory in order to store and modify the possible parameters.The advantages are that testing can be interactively carried out and not that the test program must be corrected, translated and linked again after the test evaluation in a time-consuming fashion.The method is advantageously utilized in the development of communications software.

Abstract: In a transmission method for simultaneous synchronous or asynchronous transmission of K data sequences consisting of data symbols, before transmission a specific signal form allocated to the data sequences is modulated on each of the data symbols of the K data sequences transmitted via a channel or K generally distinguishable channels, in order to generate the K transmission signals, which are all distorted by the one channel, or one of the K channels. In the receiver, continuous-valued provisional estimated values are calculated for some or all of the data symbols of the K input sequences according to a linear method, and a confidence level for the estimated values is calculated.

Abstract: A method is provided for improving the localization of a robot autonomous mobile unit. A slippage is predicted along a path that the unit is to traverse may be predicted, in that a simplified absolute path trajectory is determined, and based on the unit geometry and motion behavior of three-wheel kinematics, an imaginary slippage derives in the end position. This imaginary slippage can be calculated for various end positions and the most beneficial travel path can thus be selected from a starting point.

Abstract: The method is for controlling performance features of an exchange. In step a) a static table of performance feature object codes, having corresponding code values, is transmitted from the exchange to a terminal equipment during an equipment initialization. The static table of performance feature object codes is specific for the exchange and contains all performance features available in the exchange. Information for the specification of the performance feature object is allocated to each performance feature object code value. In step b) the static table of performance feature object codes is stored in the terminal equipment. In step c) a dynamic table of performance feature object codes, which correspond to the performance features that can be activated in the respectively current switching-oriented state of the terminal equipment, is transmitted from the exchange to the terminal equipment.

Abstract: Different bonus values and penalty values are allotted for each partial task of the unit such as, for example, drive from A to B, hold your positional uncertainty below a specific threshold, or draw up a map of the surroundings and add landmarks to it. Performance weightings for the individual tasks are yielded, in conjunction with a need to carry the latter out, after analysis of the bonus values and penalty values, and are evaluated in a control unit. Furthermore, in the context of the method a local planning horizon is specified in which the surroundings of the unit are subdivided into grid cells. Preferred directions, which lead the unit by the shortest path to already known or unconfirmed landmarks are stored for these grid cells, with the aim of reducing the positional uncertainty, or of being able to confirm a landmark. All the different routes which are possible within the framework of this grid are then investigated as to what contribution they make to enable the unit to reach the goal.

Abstract: A differential current protective device for a transformer arranged in a multi-phase power supply system and having at least one star-connected winding arrangement with a grounded star point. The differential current protective device receives currents proportional to the system currents via current transformers provided on the high and low voltage sides of the transformer. A computing circuit of the protective device determines a differential phase-related current from the currents measured, taking into account a current parameter that corresponds to the zero system current based on the phase and whose intensity is monitored. The differential current protective device includes an auxiliary current transformer having its primary winding in the connection between the star point and ground. The computing circuit processes the secondary current of the auxiliary current transformer as the current parameter corresponding to the zero system current.

Abstract: Crack stops for substantially preventing cracks and chips produced along the dicing channel from spreading into the active areas of the ICs are described. The crack stops are formed by creating discontinuities in the thickness of the dielectric layer in the dicing channel near the chip edges. The discontinuities can result in increasing and/or decreasing the thickness of the dielectric layer.

Abstract: An adaptation method for correcting tolerances of a transducer wheel includes determining a correction factor for each individual tooth or each segment of the transducer wheel by measuring angular speed while taking into account both production tolerances and variations from one manufactured part to another of its kind as well as noncentral support of the transducer wheel on the shaft. The correction factor also compensates for a mass moment caused by a piston and a connecting rod. In an adaptation algorithm, a periodic disturbance by a gas moment caused by varying cylinder pressures and a moment fed back from the road are taken into account.

The contact areas comprise end areas that form a contact plane that is coplanar to the substrate during assembly and soldering.

Abstract: Direct voltage and alternating voltage signals are decoupled from a first and a second pair of leads. The pairs of leads each carry an alternating voltage signal and they are subject to a direct voltage between them. A capacitive connection of the leads with the inputs of a signal receiving device allows decoupling of the alternative voltage signal. For decoupling one pole of the direct voltage signal, diodes are provided that are connected to the leads of the respective pair of leads. The diodes are each connected via a respective current source transistor to one terminal for the pole of the direct voltage. The control terminals of the current source transistors are controlled by the center tap of a voltage divider connected between the diodes. The embodiment for direct voltage decoupling is readily integratable.

Abstract: In order to avoid uncontrolled secondary damage to a fuel rod, in particular a fuel rod being formed of Zircaloy and having a liner on the inside, in which the secondary damage may be generated by coolant that enters the fuel rod in the event of primary damage, a nucleus is deliberately provided in a cladding tube. The nucleus, although passivated in an undamaged fuel rod and not impeding the serviceability of the fuel rod, is activated by coolant which enters the fuel rod in the event of primary damage or by hydrogen or other reaction products produced in reactions of the coolant in the interior of the fuel rod and results in a small-area perforation. This prevents an aggressive atmosphere, which may result in unintentional large-area secondary damage at other points, from accumulating in the cladding tube after primary damage.
