  • Patent number: 6408290
    Abstract: One aspect of the invention is the construction of mixtures of Bayesian networks. Another aspect of the invention is the use of such mixtures of Bayesian networks to perform inferencing. A mixture of Bayesian networks (MBN) consists of plural hypothesis-specific Bayesian networks (HSBNs) having possibly hidden and observed variables. A common external hidden variable is associated with the MBN, but is not included in any of the HSBNs. The number of HSBNs in the MBN corresponds to the number of states of the common external hidden variable, and each HSBN is based upon the hypothesis that the common external hidden variable is in a corresponding one of those states. In one mode of the invention, the MBN having the highest MBN score is selected for use in performing inferencing.

  • Patent number: 6389090
    Abstract: For a digital communications receiver, a clock and data signal recovery circuit and method use an all digital delay locked loop timed by an on-chip transmit clock signal. The digital delay locked loop includes a phase detector and loop filter. The phase detector determines, for each data signal rising or falling edge, if the current delay of a reference clock signal leads or lags the data signal edge. The loop filter examines the stream of such lead/lag indications, performs a nonlinear filtering process thereon, and in response increases or decreases the clock signal phase appropriately.

  • Patent number: 6377110
    Abstract: Apparatus, specifically a circuit (100, 200), for a highly accurate, low cost temperature sensor, particularly one using silicon thermometry and which can be implemented by an application specific integrated circuit, that also possesses a high degree of linearity and a wide dynamic range. The inventive circuit advantageously utilizes either a mixed-signal approach or a digital core and provides independent adjustment, through two point calibration, of slope and ambient output offset values, with a zero offset adjustment advantageously accomplished through use of a digital tear. Specifically, given the inherent linearity of silicon thermometry, zero offset and desired output voltage are set, independently of each other, at a first predefined ambient calibration temperature as effectively two separate offset values, while slope (span) is set at a second predefined calibration temperature (typically a full scale temperature) different from the first temperature.

  • Patent number: 6373305
    Abstract: A digital PLL's stability and immunity to jitter are improved by deriving the correction to the state machine count from an average over several computations of the phase error, and re-initializing the computation of the phase error to the residual error remaining after the correction. The PLL stability is improved by retaining all of the phase errors measured during a succession of plural phase measurement intervals and by retaining the residual error in the next cycle of cumulative phase error. The plurality of phase errors thus obtained are averaged together starting from the residual error left over from the previous cycle, and the state machine internal count is corrected (updated) in accordance with this average, rather than according to an instantaneous phase error. As a result, the performance of the PLL is less susceptible to jitter-induced temporary excursions in the phase error, a significant advantage.

  • Patent number: 6369723
    Abstract: In rows (1) of data elements (11, 12), there may occur special data elements, such as control characters. By replacing each special data element (12) by a replacement data element (14), which contains a positional indication of a next special data element (12′) and which does not correspond to a special data element (12), it is possible to reproducibly remove all special data-elements from the row (1) without the length of the row increasing essentially. only one single supplementary data element (13) is required for transmitting the positional indication of the first special data element.

  • Patent number: 6363065
    Abstract: Apparatus, and accompanying methods for use therein, for a telephony gateway intended for use, e.g., paired use, at opposite ends of a data network connection, in conjunction with at each end, e.g., a private branch exchange (PBX) for automatically routing telephone calls, e.g., voice, data and facsimile, between two peer PBXs over either a public switched telephone network (PSTN) or a data network, based on, among other aspects, cost considerations for handling each such call and called directory numbers, monitoring quality of service (QoS) then provided through the data network and switching (“auto-switching”) such calls back and forth between the PSTN and the data network, as needed, in response to dynamic changes in the QoS such that the call is carried over a connection then providing a sufficient QoS. To support auto-switching, the apparatus embeds, using call independent signaling, certain call-specific information, as non-standard data, within various conventional H.

  • Patent number: 6356970
    Abstract: In a system having an DSP, an ASIC and a memory, in which the ASIC generates a number of different competing interrupts for the DSP to service, the ASIC has an interrupt request control module which automatically provides the DSP with a vector pointing to the memory location of the interrupt service routine for the currently pending interrupt request having the highest priority of all pending requests. The DSP reads this vector and uses it to access the interrupt service routine in the memory. Reading of this vector causes the interrupt request to be de-asserted, which causes the next highest priority pending interrupt request to become the highest priority pending interrupt request. As a result, a new vector is presented for the next read by the DSP.

  • Patent number: 6356306
    Abstract: A digital camera includes a CPU. The CPU releases a bus according to a bus-release request from a memory control circuit, and supplies a bus grant signal to the memory control circuit. Accordingly, the image data from a first signal processing circuit is written into a VRAM according to DMA. When the writing of the image is ended, the memory control circuit cancels the bus release request. The CPU accesses to the VRAM through the bus, to utilize the VRAM as a working memory.

  • Patent number: 6353813
    Abstract: Matching (e.g., via correlation or similarity process) entities having attributes, some of which have associated values. The values of the attributes may be adjusted based on number of entities that have values for a particular attribute so that the values decrease as the number increases. The attributes of the entities may be harmonized and provided with default values so that entities being matched have common attributes defined by the union of the attributes of the entities being matched. The attributes of the entities may be expanded and provided with default values so that the entities being matched have attributes that neither had originally. Match values may be normalized to provide a weight value which may be used to predict an attribute value of a new entity based on known attribute values of known entities. The weight values may be tuned such that relatively high weights are amplified and relatively low weights are suppressed.

  • Patent number: 6336108
    Abstract: The invention performs speech recognition using an array of mixtures of Bayesian networks. A mixture of Bayesian networks (MBN) consists of plural hypothesis-specific Bayesian networks (HSBNs) having possibly hidden and observed variables. A common external hidden variable is associated with the MBN, but is not included in any of the HSBNs. The number of HSBNs in the MBN corresponds to the number of states of the common external hidden variable, and each HSBN models the world under the hypothesis that the common external hidden variable is in a corresponding one of those states. In accordance with the invention, the MBNs encode the probabilities of observing the sets of acoustic observations given the utterance of a respective one of said parts of speech. Each of the HSBNs encodes the probabilities of observing the sets of acoustic observations given the utterance of a respective one of the parts of speech and given a hidden common variable being in a particular state.
