ActiveUS20050013479A1Easy to detectImprove efficiencyCharacter and pattern recognitionPattern recognitionFace detection
Face detection techniques are provided that use a multiple-stage face detection algorithm. An exemplary three-stage algorithm includes a first stage that applies linear-filtering to enhance detection performance by removing many non-face-like portions within an image, a second stage that uses a boosting chain that is adopted to combine boosting classifiers within a hierarchy “chain” structure, and a third stage that performs post-filtering using image pre-processing, SVM-filtering and color-filtering to refine the final face detection prediction. In certain further implementations, the face detection techniques include a two-level hierarchy in-plane pose estimator to provide a rapid multi-view face detector that further improves the accuracy and robustness of face detection.

Reactor in deposition device with multi-staged purging structure
InactiveUS20130337172A1Easy to disassembleChemical vapor deposition coatingEngineeringVenturi effect
Embodiments relate to a structure of reactors in a deposition device that enables efficient removal of excess material deposited on a substrate by using multiple-staged Venturi effect. In a reactor, constriction zones of different height are formed between injection chambers and an exhaust portion. As purge gas or precursor travels from injection chambers to the exhaust portion and passes the constriction zones, the pressure of the gas drops and the speed of the gas increase. Such changes in the pressure and speed facilitate removal of excess material deposited on the substrate.

Parallel network processor array
InactiveUS6854117B1Account can be blockedDigital computer detailsMultiprogramming arrangementsMultiple contextParallel processing
A method and system performs parallel processing of asynchronous processes on ordered entities. A system focuses on the average time and variance of the variable time process. Each processor can run multiple contexts. The processing may be divided into a number of stages, each of which can be performed by each of the processors. A system also needs to ensure that the order of the entities is preserved as desired. This order may be maintained by performing some type of pre-processing on the entities to determine their order, and then not starting processing on an entity until the processing of any entity which must precede that entity has been completed. For processing of packets in a network, it may be needed to ensure that packets in the same flow maintain their order after processing. A system also may determine the number of processors that optimally are needed in order to process an incoming stream of entities at a desired speed. This computation may depend on how many different contexts each processor runs. In addition, this computation also may depend on whether there is an input buffer available to store the incoming entities, and the capacity of such an input buffer.

Exhaust aftertreatment system using urea water
InactiveUS20070036694A1Avoid depositionReduced responseCombination devicesInternal combustion piston enginesHandling systemMultiple stages
An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.

InactiveUS7579153B2Minimizes amplification biasThe process is fast and accurateMicrobiological testing/measurementFermentationReverse transcriptaseNucleotide
The present invention provides for amplification of one or more polynucleotides by multi-staged linear amplifications using one or more RNA polymerases. At each stage RNA transcripts are accumulated at a linear rate, so that multiple stages provide for faster than linear transcript accumulation. In one aspect, the invention provides for polynucleotide amplification by ligating hairpin adaptors to an end of polynucleotides wherein the hairpin adaptors each contain a promoter sequence oriented so that transcription proceeds in the direction of the loop of the hairpin adaptor. Upon transcription through such loop region and to the complementary strand a replicate is made of the promoter sequence as well as the polynucleotide, thereby permitting exponential amplification upon reverse transcription, second strand synthesis, and repetition of the above cycle. Preferably such amplification is carried out under isothermal reaction conditions.

Scheduling the dispatch of cells in multistage switches
InactiveUS7173931B2Improve throughputAvoid switchingTime-division multiplexData switching by path configurationSecondary stageMulti phase
A multiple phase cell dispatch scheme, in which each phase uses a simple and fair (e.g., round robin) arbitration methods, is described. VOQs of an input module and outgoing links of the input module are matched in a first phase. An outgoing link of an input module is matched with an outgoing link of a central module in a second phase. The arbiters become desynchronized under stable conditions which contributes to the switch's high throughput characteristic. Using this dispatch scheme, a scalable multiple-stage switch able to operate at high throughput, without needing to resort to speeding up the switching fabric and without needing to use buffers in the second stage, is possible. The cost of speed-up and the cell out-of-sequence problems that may occur when buffers are used in the second stage are therefore avoided.
