  • Patent number: 6240386
    Abstract: A multi-rate speech codec supports a plurality of encoding bit rate modes by adaptively selecting encoding bit rate modes to match communication channel restrictions. In higher bit rate encoding modes, an accurate representation of speech through CELP (code excited linear prediction) and other associated modeling parameters are generated for higher quality decoding and reproduction. For each bit rate mode selected, pluralities of fixed or innovation subcodebooks are selected for use in generating innovation vectors. The speech coder distinguishes various voice signals as a function of their voice content. For example, a Voice Activity Detection (VAD) algorithm selects an appropriate coding scheme depending on whether the speech signal comprises active or inactive speech. The encoder may consider varying characteristics of the speech signal including sharpness, a delay correlation, a zero-crossing rate, and a residual energy.

  • Patent number: 6071400
    Abstract: The invention relates to a method and device for the electrochemical treatment of electrically mutually insulated, electrically conductive areas on an item to be treated by means of a treatment liquid. Insulated, for example etched structures on circuit boards cannot be treated electrochemically with known methods since there exists no electrical connection to the bath current source from individual areas. According to the invention, this connection is produced by brushes which touch the structured surfaces to be treated with their electrically conductive and thin fibres. A large number of brushes which are arranged transversely to the direction of transportation take care of the fact that all the electrically conductive areas on the item to be treated which are arranged in an insulated manner from one another are contacted electrically at least one after another and that the achieved contact time is sufficiently long.

  • Patent number: 5186797
    Abstract: Disclosed is an in-line electrolytic deflash system and method for removing resin bleed and other materials from the leads of an encapsulated electronic component. An encapsulated electronic component is carried on a continuous belt through the system. The component first passes through an electrolytic deflash station which includes tanks filled with a deflash solution for loosening the resin bleed. The component is then rinsed in a low pressure rinse station, and then carried through a high pressure rinse station where the loosened resin bleed is removed from the component. The component is then further rinsed with both tap water and a deionized water. Once the component has been sufficiently rinsed any remaining moisture is blown off the part in an air knife station and the component is then passed through a dryer which completely removes any moisture remaining on the component.
