  • Patent number: 6219420
    Abstract: A processor (22) of an encryption system (20) receives plain text (24) and operates an encryption algorithm to convert the plain text (24) to cipher text (26). A state monitor (30) confirms a conversion sequence within each of a plurality of conversion cycles performed by the encryption algorithm. The state monitor (30) produces a first enablement signal (38) when the conversion sequence is confirmed. An encryption activity monitor (34) determines a number of blocks of cipher text (24) that are not encrypted. The encryption activity monitor (34) produces a second enablement signal (42) when the number of unencrypted blocks of cipher text (26) is less than a predetermined failure threshold (86). A monitor gate (36) enables output of the cipher text (26) in response to the first and second enablement signals (38, 42).

  • Patent number: 6215780
    Abstract: In a code division multiplexed system, a subscriber unit (260, FIG. 1), which includes a pseudonoise code generator (70), is synchronized with the pseudonoise code generator (220) of a communications node (200). Synchronization between the pseudonoise code generators (70, 220) is achieved through measuring the time delay of a signal transmitted from the communications node (200) to the subscriber unit (260) and advancing the code generator of the subscriber unit in accordance with the time delay. This permits transmissions from the subscriber unit (260) to be received synchronously at the satellite. The synchronization is maintained through the periodic transmission from the communications node (200) to the subscriber unit (260) of a message which commands the subscriber unit (260) to adjust the timing of its pseudonoise code generator. The resulting synchronous code division multiplexed system offers increased capacity over conventional systems.

  • Patent number: 6199040
    Abstract: System efficiently communicates a perceptually encoded speech spectrum signal from a transmitter to a receiver. The transmitter includes a speech analyzer which accepts a speech signal input and generates a parameterized speech signal. The transmitter also includes a vector quantizer for generating the perceptually encoded speech spectrum signal from the parameterized speech signal. The receiver decodes the perceptually encoded speech spectrum signal to produce decoded spectral parameters to further produce a synthetic speech output. The vector quantizer performs a method for partitioning a vector quantizer (VQ) codebook to produce perceptually organized sub-codebooks. The vector quantizer performs a second method for quantizing a vector based on the perceptually organized sub-codebooks. The second method identifies a vector, from one of the perceptually organized sub-codebooks, to perceptually model the speech signal input.

  • Patent number: 6192353
    Abstract: An improved method and system for training and classifying using a low complexity and high accuracy multiresolutional polynomial classifier (412) is presented. A method of training an multiresolutional polynomial classifier which reduces the complexity of existing classifiers allows models representing subgroups of classes to easily be created. The models which represent subgroups of classes are applied to an unidentified input to produce a coarse classification of the unidentified input using a low order classifier. Once a coarse classification of the unidentified input is performed, a more detailed classification is performed using another low complexity classifier.

  • Patent number: 6185408
    Abstract: A method and apparatus for rapidly characterizing a communications channel is used to mitigate the effects of the communications channel as present in a received signal. A satellite (20) transmits a data signal (40) and a pilot signal (50). The data signal (40) and the pilot signal (50) are substantially orthogonally polarized. A user terminal (30) receives the orthogonally polarized data signal (40) and pilot signal (50). The user terminal includes a channel information recovery circuit (250) and a channel effects mitigation circuit (240). The channel information recovery circuit (250) characterizes the communications channel by analyzing the pilot signal (50), and then provides the channel information (260) to the channel effects mitigation circuit (240) which then mitigates the effects of the channel.

  • Patent number: 6166451
    Abstract: A distributed airbag firing system (10) includes a controller (12) receiving sensor signals from a sensor (20) over a two-wire bus (18). The controller provides a firing command over to the two-wire bus to a squib driver circuit (26), which provides the firing current necessary to detonate a squib device (32) and inflate the airbag. The squib driver circuit includes a rectifier (42) with its first and second inputs interchangeably connected to the two-wire bus. The rectifier circuit converts the voltage orientation on the first and second conductors to a positive potential on a first output conductor and a negative or ground potential on a second output conductor. The interchangeability of the first and second inputs of the rectifier to the two-wire bus makes the connection arbitrary and fail-safe.
