  • Publication number: 20080243514
    Abstract: A user interface, and associated techniques, that permit a fast and efficient way of correcting speech recognition errors, or of diminishing their impact. The user may correct mistakes in a natural way, essentially by repeating the information that was incorrectly recognized previously. Such a mechanism closely approximates what human-to-human dialogue would be in similar circumstances. Such a system fully takes advantage of all the information provided by the user, and on its own estimates the quality of the recognition in order to determine the correct sequence of words in the fewest number of steps.

  • Patent number: 7054958
    Abstract: In a data processing system including a plurality of digital signal processor subsystems, selected peripheral components are shared by the digital signal processor subsystems. In particular, the high level data link controller is shared by the subsystems. Using a first interrupt signal after each transfer of signal groups from the peripheral direct memory access unit, the data can be efficiently transferred from a channel memory of the peripheral direct memory access unit to the high level data link controller. A second interrupt from the high level data link controller when a last word of a packet is transferred thereto causes a new channel memory to be accessed. An abort signal is generated when a signal group for a packet being processed by the high level data link controller is not available in a timely manner.

  • Patent number: 6823402
    Abstract: In a data processing system including a plurality of digital signal processor subsystems, selected peripheral components are shared by the digital signal processor subsystems. In particular, the high level data link controller is shared by the subsystems. When a packet is received by a shared high level data link controller, the data signal groups are processed and placed in a temporary storage unit. The address signal group of the received packet is applied to channel block unit where the digital signal processor subsystem, to which the packet is directed, is identified and an INTERRUPT signal corresponding to the identified digital signal processor subsystem is generated. The INTERRUPT signal is applied to a switch. The switch, which receives the signal groups from the temporary storage unit, directs the signal groups to a buffer memory in the channel associated with the identified signal processing subsystem.

  • Patent number: 5468401
    Abstract: A carrier-free pulverulent metalworking lubricant composition. In one preferred form, the composition contains at least two lubricant components one of which comprises a resin having a highly polar functional group the composition being formed by a method comprising the steps of: (a) forming a dry mixture of said particulate lubricant components, and (b) agglomerating said admixture to form agglomerated particles. The application of the composition as a metal working lubricant significantly reduces smoke and oily waste generation in hot forging operations by eliminating the use of oils or volatile organic compounds as carriers, while providing acceptable performance, cleanability, and sprayability.

  • Patent number: 5081645
    Abstract: A system comprising apparatuses and methods for encoding and decoding spread spectrum signals is disclosed. Signals are encoded by modulating numerical sequences selected from an orthonormal basis of numerical sequences to provide channel coding. The modulated sequences are then combined to form an encoded signal. Because of the orthonormal character of the sequences, the encoded signal may be easily decoded using a matched filter. A method for generating long sequences from the product of shorter sequences is also disclosed.
