    摘要: The present invention refers to a surface ionization detector comprises an emitter, a heating rod, a collecting electrode, a reducing liner and a housing. The emitter is made of molybdenum, platinum or alloy, and in the form of cylinder or a wire spiral. The heating rod heats and supports the metal emitter. When the heating rod is heated to 300-500° C., organic amine compounds collide with the surface of the emitter, generating positive ions through surface thermal ionization and thus are detected. The lowest detecting limit value of tertiary amine by the detector in the present invention can achieve to 10−14 g/s. The response to other hydrocarbons, ketones, etc., is 5-6 orders of magnitude lower than that of organic amines. The detector can selectively detect amines, hydrazines and their derivatives, and so on. The detector can be used as a detector for a gas chromatography system adopting capillary column or packed column, or alternatively be used alone as a sensor.

    摘要: A method and apparatus for frame classification and rate determination in voice transcoders. The apparatus includes a classifier input parameter preparation module that unpacks the bitstream from the source codec and selects the codec parameters to be used for classification, parameter buffers that store previous input and output parameters of previous frames, and a frame classification and rate decision module that uses the source codec parameters from the current frame and zero or more frames to determine the frame class, rate, and classification feature parameters for the destination codec. The classifier input parameter preparation module separates the bitstream code and unquantizes the sub-codes into the codec parameters. The frame classification and rate decision module comprises M sub-classifiers and a final decision module. The characteristics of the sub-classifiers are obtained by a classifier construction module, which comprises a training set generation module, a learning module and an evaluation module.

    摘要: A method of removing a motion vector from a group of motion vectors used in an encoding process includes providing a list of motion vectors, selecting an initial motion vector from the list of motion vectors, and providing an intermediate motion vector using a motion vector refinement process. The motion vector refinement process uses, in part, the initial motion vector. The method also includes forming a region defined by one or more parameters associated with the initial motion vector and one or more parameters associated with the intermediate motion vector, selecting an additional motion vector from the list of motion vectors, determining that the additional motion vector points into the region, and modifying a state of the additional motion vector.

    摘要: A variable rate compressed voice signal domain transcoder that transcodes a bitstream representing frames of data encoded according to a first voice compression standard to a bitstream representing frames of data according to a second voice compression standard; the second voice compression standard defines a variable-rate voice codec. The method includes unquantizing a bitstream into a first set of parameters compatible with a first compression standard. The first set of parameters in addition to external control commands are then used to determine the frame class and rate for the second compression standard. Next, the first set of parameters are transformed into a second set of parameters compatible with a second compression standard according to the frame-classification and rate determination decision without converting the first set of parameters to an analog or digital voice waveform representation. The transformation approaches can be varied and further optimized based on the characteristics of the pair of first compression standard and the second compression standard. Lastly, the second set of parameters is packed into a bitstream compatible with the second compression standard.

    摘要: The present invention provides a resin composition consisting of a functionalized polypropylene (PP) and a functionalized styrenic thermoplastic elastomer (TPS). The functionalized PP is a PP grafted with N-vinyl pyrrolidone (NVP) and glycidyl methacrylate (GMA), and the functionalized TPS is a TPS grafted with acrylamide or methacrylamide. The functionalized PP and the functionalized TPS are subjected to melt blending to obtain the resin composition with a slight cross-linking structure due to the reaction between GMA and acrylamide or methacrylamide, therefore the resin composition presents good physical properties. Besides, the resin composition without additional plasticizer or other small molecular organic compounds can be utilized in blood bags, blood transfusion and collection apparatuses, etc. Thus, it does not release small molecular substances which are of potential harm to human body during use.
