Abstract: To avoid an over-adaptation of a current acoustic model (CAM) to certain and frequently occuring words for speech phrases during on-line speaker adaptation of speech recognizers it is suggested to count adaptation numbers (aj) for each of said speech phrases (SPj) as numbers of times in that a distinct speech phrase (SPj) has been used as a basis for adapting said current acoustic model (CAM) and further to make the strength of adaptation of the current acoustic model (CAM) on the basis of said distinct speech phrase (SPj) dependent on its specific adaptation number (aj) so as to decrease the influence of frequent speech phrases (SPj) in the received speech flow on the adaptation process.

Abstract: There is proposed a method that may be universally used for controlling a man-machine interface unit. A learning sample is used in order at least to derive and/or initialize a target action (t) to be carried out and to lead the user from an optional current status (ec) to an optional desired target status (et) as the final status (ef). This learning sample (l) is formed by a data triple made up by an initial status (ei) before an optional action (a) carried out by the user, a final status (ef) after the action taken place (a).

Abstract: To provide a higher data rate service on one link, it is possible to use more than one scrambling code per link. In this way, the same channelization code can be reused and a higher data rate can be supported because the highest data rate is restricted by the set of channelization codes with the shortest length. When reusing one and the same channelization code for spreading the two different data streams transmitted in one link and scrambling these two data streams by two different scrambling codes, the complexity of the receiver will be reduced. Therefore, the two data streams are spread with one and the same channelization code. After this, each of these data streams is scrambled with a different scrambling code.

Abstract: A method for post-processing compressed image data for reducing blocking artifacts is suggested, in which a set of primary image data (PID) is decomposed into data sets (IID1, IID2) containing the fine structure of the image with structure being smaller than the blocking artifacts and without the blocking artifacts and structures being larger than or comparable to the blocking artifacts as well as the blocking artifacts, respectively. In the decomposition of the primary image data (PID) a non-linear filtering process (F1) is involved. After decomposition of the primary image data (PID) a filtering process (F3) can be applied to the set of intermediate image data (IID2) containing larger details of the image as well as the blocking artifacts. Therefore, in the process of filtering out the blocking artifacts, the fine structure of the image is not influenced.

Abstract: A light orientation film and a liquid crystal thin film are formed adjacent to each other. Light is irradiated to the light orientation film and the liquid crystal thin film, so as to cause the light orientation film to be orientated while viscosity of the liquid crystal thin film is lowered by a temperature increase by the light irradiation, so that an intermolecular force on the boundary between the light orientation film and the liquid crystal thin film causes the liquid crystal molecules in the liquid crystal thin film to the orientation of the light orientation film. By this orientation of the liquid crystal molecules, recording information is maintained. Thus, it is possible to realize a sufficient signal amount while using the light orientation film as well as to obtain a thermal stability and a stability against light irradiation.

The universal platform is based on the linear operation of the devices. Thus, the DC offset problem may be solved. It is also possible to support very wide bandwidths compared with conventional I/Q receivers. Therefore, the present universal platform is suitable for multimode and multiband communications.

Abstract: A packet synchronization detector for an incoming digital signal which includes a regularly repeated predetermined synchronization pattern which repetition rate defines the length of one transmission packet according to the present invention comprises a synchronization pattern detector (1) and several synchronization state machines (2, 31, . . . , 3n) which respectively determine whether or not one detected synchronization pattern with a respective position in regard to the length of one transmission frame has the correct repetition rate to determine whether or not lock has been achieved. Therefore, a very fast lock is achieved, since also in case of bit patterns that match to the synchronization byte, but that are not the synchronization byte no penalty time occurs to lock to the incoming digital signal.

Abstract: A demodulator for modulated RF signals comprises a passive four port structure (1). The four port structure (1) has a first input (3) for supplying a modulated RF signal to be demodulated. A second input (2) is supplied with a RF signal from a local oscillator (21). Two output terminals are connected to power sensors (4, 5). The RF signal from the local oscillator (21) is supplied to the second input (3) of the four port structure (1) without being RF switched by an RF switch. The demodulator is particularly useful for modulation schemes with a finite number of magnitude states (nQAM modulation).

Abstract: To prevent adaptation to misrecognized words in unsupervised or on-line automatic speech recognition systems confidence measures are used or the user reaction is interpreted to decide whether a recognized phoneme, several phonemes, a word, several words or a whole utterance should be used for adaptation of the speaker independent model set to a speaker adapted model set or not and, in case an adaptation is executed, how strong the adaptation with this recognized utterance or part of this recognized utterance should be performed. Furtheron, a verification of the speaker adaptation performance is proposed to secure that the recognition rate never decreases (significantly), but only increases or stays at the same level.
