Abstract: In order to effectively error-correct decode a plurality of data frames transmitted over a noisy transmission channel, control data is applied to a maximum-likelihood decoder such as to change decoding parameters thereof.  The control data is generated based on frame characteristic information obtained from at least one data frame which precedes a data frame currently decoded at the maximum-likelihood decoder. Thus, the error-correct decoding is implemented using estimated correlation between at least two consecutive data frames one of which is under error-correct decoding. Further, a cyclic code decoder is provided in a receiver for checking a transmission error in the output of the maximum-likelihood decoder.  The cyclic code decoder issues a check result which is used to change the contents of the control data.

Abstract: Dispositif de co-exécution servant à exécuter des fonctions déchargées à partir d'unités centrales (UC) dans un système de traitement des données, tel que demandé par un ou plusieurs programmes de commande d'exécution. Ce dispositif inclut un système d'exploitation central ainsi que des programmes et des applications de sous-système fonctionnant au moyen de ce même système. Les fonctions déchargées sont incluses dans des modules de code. Ces modules exécutent un traitement dans le dispositif de co-exécution, en parallèle avec des fonctions non déchargées étant exécutées par les UC. Ces dernières n'ont pas besoin d'exécuter des fonctions qui peuvent être exécutées par le dispositif de co-exécution. Dans les demandes des UC acheminées au dispositif de co-exécution, on précise les modules de code auxquels le dispositif accède à partir d'une mémoire commune d'unité, selon les mêmes contraintes et limites d'accès que les programmes de commande. Le dispositif de co-exécution peut émuler une traduction dynamique d'adresse centrale, et peut utiliser une clé de protection centrale pour accéder à la mémoire centrale. L'état d'exploitation de réserve pour le dispositif de co-exécution maintient l'intégrité des données. Les dispositifs de co-exécution peuvent être de la même architecture que les UC, ou être d'une architecture totalement différente, afin de fournir un environnement de traitement efficace pour les fonctions déchargées. Les interfaces de co-exécution reçoivent des logiciels qui fournissent les demandes au dispositif de co-exécution. Les modules déchargés, une fois que le dispositif de co-exécution y a accédé, peuvent être mis en antémémoire dans la mémoire locale de co-exécution pour être utilisés lors de demandes futures, afin de permettre que des appels subséquents puissent être traités sans avoir à attendre pour charger de nouveau le même module.

Title: Speech recognition method using a two-pass search
Inventor: GUPTA VISHWA NATH
IPC: G10L15/14
Filed: 1994-05-18
Granted: 2000-01-25
Abstract: A speech recognition method uses a two-pass search to match an unknown utterance to a vocabulary word. Words in the vocabulary are represented by concatenated allophone models and the vocabulary is represented as a network. On the first pass of the search, a one-state duration constrained model is used to search the vocabulary network. The one-state model has as its transition probability the maximum observed transitional probability (model distance) of the unknown utterance for the corresponding allophone model. Words having top scores are chosen from the first pass search, and rescored using a full Viterbi trellis with the complete allophone models and model distances. The rescores are sorted to provide a few top choices. Using a second set of speech parameters these few top choices are again rescored. Comparison of the scores using each set of speech parameters determines a recognition choice. Post processing is also possible to further enhance recognition accuracy. Test results indicate that the two pass search provides approximately the same recognition accuracy as a full Viterbi search of the vocabulary network.

Abstract: The invention relates to computationally efficient sophisticated perceptual models which can provide a basis for adaptive bit allocation and quantization of encoded information useful in high-quality low bit-rate coding systems. In one embodiment, an audio split band encoder splits an input signal into frequency subband signals, quantizes the subband signals according to values established by an allocation function, and assembles the quantized subband signals into an encoded signal. The allocation function establishes allocation values in accordance with psychoacoustic principles based upon a masking threshold. The masking threshold is established by estimating the power spectral density (PSD) of the input signal, generating an excitation pattern by applying a spreading function to the PSD, adjusting die excitation pattern by an amount equal to a signal-to-noise ratio (SNR) offset sufficient to achieve psychoacoustic masking, comparing the level of the adjusted pattern to the threshold of hearing and generating a masking threshold which is equal to the larger of the two. The spreading function may be implemented by applying one or more non-recursive filters to the input signal PSD. In forward-adaptive coding systems, allocation values are explicitly conveyed to a decoder by information assembled into the encoded signal. In backward-adaptive coding systems, allocation values an implicity conveyed to a decoder by information assembled into the encoded signal from which a decoder allocation function may derive the allocation values. In hybrid-adaptive coding systems, basic allocation values are conveyed implicitly with modified allocation values conveyed explicitly.

Abstract: It is possible by means of this device to fill a shell body with sub-projectiles in a defined geometric arrangement in a very short time without errors being created by shifting.  Prior to filling, the sub-projectiles (20) are combined into layers (40) for this purpose, which are as thick as the length of the sub-projectiles (20) and which extend in planes transversely to the longitudinal axis (43) of the shell body.  The sub-projectiles (20) take up a position in the layer (40) which corresponds to their geometric arrangement in a hollow chamber (42) of the shell body.  During the combination, the circumference of the layers (40) is shaped in such a way that, following the insertion of a layer (40) into the hollow chamber (42), the sub-projectiles (20) are held therein fixed against relative rotation while maintaining the previously formed geometric arrangement.  In accordance with a preferred embodiment, the circumference of the layers (40) has the shape of a regular hexagon, wherein the axes of the sub-projectiles (20) consisting of cylinders extend parallel with the longitudinal axis (43) of the shell body.
