Abstract: A method for analyzing the contact assignment of a contact element of a cell module for a vehicle battery to charge or discharge individual cells. A module charger charges/discharges the cell module and includes a diagnosis function for the contact assignment of the contact element. A method is disclosed for operating a module charger, which allows for charging and discharging cells of different cell modules with different contact assignments and automatically prevents incorrect operation. The method includes connecting a contact element of a diagnosis unit corresponding to the contact element to establish an electrical connection with each contact. A voltage measurement is taken of a contact against all other individual contacts, and the voltage values assigned to the contacts are saved. Then, based on the assigned voltage values, the contact assignment with respect to the individual cells is determined and, finally, the cell module is charged or discharged.

Abstract: An attenuation device for attenuating sound waves, and a corresponding system and method, generated by a source emitting sound waves having frequencies between f1 and f2 and wherein the pressure levels are between n1 and n2. The attenuation device comprising at least one acoustic absorber comprising at least one non-linear membrane; the attenuation device being configured in such a way that the first face of the absorber is in acoustic communication with the source. The attenuation device also comprises at least one coupling element for coupling the second face with the source, the coupling element being configured to transmit to the second face sound waves according to the sound waves emitted by the source, and of which the phase and/or the amplitude leads to a pressure differential of the sound waves arriving respectively on the first and second face at the same time.

Abstract: The present invention provides optical network methods and systems. In one example, a method for handling packets in a node coupled to a ring and star subnetwork may include (a) receiving in the given node a data packet on the ring subnetwork, (b) detecting a failure on the ring subnetwork, (c) determining a new transmission path to the destination node, and (d) sending the data packet along the new transmission path. In another example, an EPON may include (a) a root coupled to a ring and star subnetwork, (b) ONUs coupled to the root via a splitter/combiner and a first fiber link, (c) a second fiber link coupled to a subset of ONUs and the star subnetwork, and (d) a WDM coupler on the first fiber link that separates a first waveband of wavelengths from a second waveband of wavelengths and guides the first waveband to the star.

Abstract: A method for supporting customized tokenization of domain-specific text acomprises the steps of: loading domain-specific tokenization rules corresponding to the customized tokenization of the domain-specific text; tokenizing the domain-specific text using the loaded domain-specific tokenization rules; and, further tokenizing the domain-specific text using general purpose tokenization rules. The loading step of the inventive method can comprise: loading a speech recognition vocabulary; and, loading domain-specific tokenization rules corresponding to the speech recognition vocabulary. In addition, the tokenizing step can comprise identifying each substring in the domain-specific text matching a regular expression having a corresponding replacement pattern in the loaded domain-specific tokenization rules, and replacing each substring identified in the identifying step with the replacement pattern corresponding to the matched regular expression.
