Parallel alarm processor
InactiveUS7355512B1Waste caregiver resourcesReduce false alarm rateEvaluation of blood vesselsSensorsLower limitOxygen Saturation Measurement
A parallel alarm processor has a threshold detector, a pattern extractor, a predetermined reference pattern, a first alarm and a second alarm. The threshold detector has a first output responsive to relatively long duration oxygen desaturations. The pattern extractor has a second output responsive to relatively short duration oxygen desaturations. The predetermined reference pattern is indicative of a series of intermittent oxygen desaturations. A first alarm is triggered when the first output crosses a lower limit threshold. A second alarm is triggered when the second output matches the predetermined reference pattern. In an embodiment, an integrator inputs smoothed oxygen saturation measurements to the threshold detector, and a predictor inputs predictive oxygen saturation measurements to the pattern extractor.

Method and apparatus for automatically recognizing input audio and/or video streams
InactiveUS7194752B1Improve accuracyMinimal timeSpeech analysisAnalogue secracy/subscription systemsSingle sampleFeature set
A method and system for the automatic identification of audio, video, multimedia, and / or data recordings based on immutable characteristics of these works. The invention does not require the insertion of identifying codes or signals into the recording. This allows the system to be used to identify existing recordings that have not been through a coding process at the time that they were generated. Instead, each work to be recognized is “played” into the system where it is subjected to an automatic signal analysis process that locates salient features and computes a statistical representation of these properties. These features are then stored as patterns for later recognition of live input signal streams. A different set of features is derived for each audio or video work to be identified and stored. During real-time monitoring of a signal stream, a similar automatic signal analysis process is carried out, and many features are computed for comparison with the patterns stored in a large feature database. For each particular pattern stored in the database, only the relevant characteristics are compared with the real-time feature set. Preferably, during analysis and generation of reference patterns, data are extracted from all time intervals of a recording. This allows a work to be recognized from a single sample taken from any part of the recording.

X-ray inspection system for detecting explosives and other contraband
InactiveUS7092485B2Rapidly and accurately discriminates among different substancesQuick checkUsing wave/particle radiation meansMaterial analysis by transmitting radiationX-rayExplosive material
A baggage scanning system and method employ combined angular and energy dispersive x-ray scanning to detect the presence of a contraband substance within an interrogation volume of a baggage item. The interrogation volume is illuminated with penetrating, polychromatic x-rays in a primary fan beam from a source such as a tungsten-anode x-ray tube. An energy-dependent absorption correction is determined from measurement of the attenuation of the fan beam at a plurality of different energies. Radiation coherently scattered by substances in the interrogation volume is detected by an energy-resolved x-ray detector operated at a plurality of scattering angles to form a plurality of scattering spectra. Each scattering spectrum is corrected for energy-dependent absorption and the corrected spectra are combined to produce a scattering pattern. The experimental scattering pattern is compared with reference patterns that uniquely characterize known contraband substances. The system and method can locate and identify a wide variety of contraband substances in an accurate, reliable manner. The system provides for automated screening, with the result that vagaries of human performance are virtually eliminated. False alarms and the need for hand inspection are reduced and detection efficacy is increased.

Self-clocking n,k code word without start or stop
InactiveUS7124947B2Enhance casino-style game playEasy to processCharacter and pattern recognitionApparatus for meter-controlled dispensingProgramming languageCoding conventions
A referenceless self-clocking (n,k) bar code word allows conveyance of information without the need of any start and / or stop code pattern or other reference; a code word pattern is repeated at least in part without space therebetween according to a given n,k coding convention so that any k pair of adjacent data code elements sensed by any sensing means according to the n,k coding convention will consist of n units (e.g., bar code modules), thus allowing the data code elements of the code word to be decoded most accurately without any reference pattern. One application of this coding is on round or cylindrical objects like coins, casino chips and the like, and this coding is also well suited for linear or other coding applications wanting to convey coded information without the use of a start / stop code or reference pattern using n,k coding. This coding may or mayn't include error control, for example, as disclosed herein.

Method and system for exploiting parallelism on a heterogeneous multiprocessor computer system
InactiveUS20060123401A1Frees the application programmerSpecific program execution arrangementsMemory systemsProgramming complexityMulti processor
In a multiprocessor system it is generally assumed that peak or near peak performance will be achieved by splitting computation across all the nodes of the system. There exists a broad spectrum of techniques for performing this splitting or parallelization, ranging from careful handcrafting by an expert programmer at the one end, to automatic parallelization by a sophisticated compiler at the other. This latter approach is becoming more prevalent as the automatic parallelization techniques mature. In a multiprocessor system comprising multiple heterogeneous processing elements these techniques are not readily applicable, and the programming complexity again becomes a very significant factor. The present invention provides for a method for computer program code parallelization and partitioning for such a heterogeneous multi-processor system. A Single Source file, targeting a generic multiprocessing environment is received. Parallelization analysis techniques are applied to the received single source file. Parallelizable regions of the single source file are identified based on applied parallelization analysis techniques. The data reference patterns, code characteristics and memory transfer requirements are analyzed to generate an optimum partition of the program. The partitioned regions are compiled to the appropriate instruction set architecture and a single bound executable is produced.

Command interface using fingerprint sensor input system
InactiveUS7239227B1Enhances and securityElectric signal transmission systemsDigital data processing detailsReference patternsFinger movement
A substrate having a fingerprint sensing system usable as a command interface using finger movements. A user's fingerprint pattern is recognized and compared to previously stored reference patterns. If the fingerprint pattern matches a previously stored pattern, the user is then permitted to enter certain commands via the same interface system. For example, in the case of an automobile, a user may identify themselves with their fingerprint, and then perform such functions as unlocking the doors, setting the seat to a selected location, or even pre-starting the car prior to their entering the automobile. The very same devices which perform the fingerprint identification and sensing are also used for the input sensing and command recognition to perform the various commands. A user is thus able to securely control desired functions in an automobile, while being assured that an unauthorized user will not have access to the automobile, even as they were able to obtain the command interface device.

Systems and methods for combining subword recognition and whole word recognition of a spoken input
InactiveUS6985861B2Build accuratelyEfficient productionSpeech recognitionPhoneme recognitionSpoken language
A computer-based detection (e.g., speech recognition) system combines a word decoder and subword decoder to detect words (or phrases) in a spoken input provided by a user into a speaker connected to the detection system. The word decoder detects words by comparing an input pattern (e.g., of hypothetical word matches) to reference patterns (e.g., words). The subword decoder compares an input pattern (e.g., hypothetical words matches based on subword or phoneme recognition) to reference patterns (e.g., words) based on a word pronunciation distance measure that indicates how close each input pattern is to matching each reference pattern. The subword decoder sorts the source set of reference patterns based on a closeness of each reference pattern to correctly matching the input pattern based on generated pattern comparisons. The word decoder and subword decoder each provide an N-best list of hypothetical matches to the spoken input. A list fusion module of the detection system selectively combines the two N-best lists to produce a final or combined N-best list. The final or combined list has a predefined number of matches.
