Abstract: More customization and adaptation of coded data streams may be achieved by processing the information signal such that the various syntax structures obtained by pre-coding the information signal are placed into logical data packets, each of which being associated with a specific data packet type of a predetermined set of data packet types, and by defining a predetermined order of data packet types within one access unit of data packets. The consecutive access units in the data stream may, for example, correspond to different time portions of the information signal. By defining the predetermined order among the data packet types it is possible, at decoder's side, to detect the borders between successive access units even when removable data packets are removed from the data stream on the way from the data stream source to the decoder without incorporation of any hints into the reminder of the data stream.

Abstract: A method and a device are for an automated comparison of at least two sets of measuring values. The measuring values of the two sets are assigned respectively to one class from a finite number of classes defined by indices so that a frequency distribution is defined respectively for each of the two sets, which frequency distribution indicates for each class a frequency of the measuring values assigned to this class. A distance measure reflecting a similarity or dissimilarity between the two sets of measuring values between these frequency distributions is calculated as a function of a final value of a first auxiliary value termed here match by way of example. The first auxiliary value match is calculated by an algorithm using two sets of variables in that, with a given maximum distance dmax?1 for all integral distances d with 0?d?dmax, beginning with d=0 and continuing to larger distances d, respectively for all indices i and j at a distance from each other by the distance d.

Abstract: The invention relates to a high-temperature fuel cell system having a start burner. Such fuel cell systems are in particular operated at temperatures between 650° C. and 1000° C. due to the ion-conductive properties of the electrolytes used. It is necessary for this reason to carry out a heating before the actual operation of the systems, which takes place by an external supply of energy. The exhaust gas of a start burner of the high-temperature fuel cell system is supplied to a heat exchanger or to two heat exchangers in a series connection for the preheating of an oxidizing agent which can be supplied to at least one fuel cell at the cathode side.

At least a join area of the oxygen permeable ceramics is subsequently heated, under loading through forces, to a temperature up to 250 K below a customary sintering temperature of the oxygen-permeable ceramics. The join area is held under the loading at the temperature for 0.5 to 10 hours.

Abstract: In one embodiment, C input audio channels are encoded to generate E transmitted audio channel(s), where one or more cue codes are generated for two or more of the C input channels, and the C input channels are downmixed to generate the E transmitted channel(s), where C>E?1. One or more of the C input channels and the E transmitted channel(s) are analyzed to generate a flag indicating whether or not a decoder of the E transmitted channel(s) should perform envelope shaping during decoding of the E transmitted channel(s). In one implementation, envelope shaping adjusts a temporal envelope of a decoded channel generated by the decoder to substantially match a temporal envelope of a corresponding transmitted channel.

Abstract: It is an object of the present invention to provide a compact and low-cost system for generating ultra short high energy laser light pulses that does not use the known CPA scheme. The proposed approach is based on spectral filtering of laser light pulses of a mode locked laser source. The used mode locked laser source can be of any kind as long as its filtered residual pulse bandwidth supports pulse durations longer than 20 ps and up to 1 ns. After filtering the laser light pulses are directly amplified in an amplification element consisting of one or more amplification stages. At the same time or just after amplification the light pulses are spectrally broadened through a spectral broadening element, for example a fiber of suitably chosen core diameter and length to achieve a spectral bandwidth that is wide enough to support sub 10 ps pulses. Finally, the spectrally broadened laser light pulses are compressed by a compact dispersive element consisting of one or more Bragg gratings or a grating pair.

Abstract: A scalable information signal is protected in a more efficient and/or safe way by adopting the inter-relationship among the plurality of portions of different levels within the information signal in FEC protecting the information signal. In particular, portions of the information signal representing the information content at a higher level should have associated therewith redundancy information which is dependent not only on that part of this portion being disjoint to a respective overlapping lower level portion. Rather, redundancy information should also be dependent on the latter part so as to increase the chances of success of forward error correcting an error within the lower level portion at the reception side.

Abstract: In an X-ray computer tomograph and a method for examining a component by means of X-ray computer tomography, the component carries out a movement relative to a radiation source detector unit in at least two degrees of freedom of movement, so at least one trajectory can be produced which spans a three-dimensional space. Since the X-radiation has a three-dimensional radiation geometry, volume data can be rapidly obtained and precisely reconstructed to form a three-dimensional X-ray image. The component can be geometrically measured by means of a geometry detection unit.
