  • Publication number: 20100197259
    Abstract: A method and an apparatus for producing a signal for verifying performances of a standard radio receiver. The apparatus includes a control module adaptable for controlling data processing, a program module for controlling and storing a digital simulation signal, a conversion module carrying out D/A conversion for the digital simulation signal, and a simulation module. When validating whether the standard radio receiver is compliant to IEEE 802.15.4-2006 standard, a verifier only needs to set up parameters defining types and signal strengths of a data frame w/o noise signals, time intervals for sending out the data frame, and a count of times of sending the data frame. Based on predefined parameters, the simulation module generates a digital simulation signal which is then processed by successive hardware devices to generate a simulated verification signal needed for validating the standard radio receiver.

  • Patent number: 7531225
    Abstract: The present invention belongs to the field of polymerization and processing of polymer and relates to the preparation of a kind of functional polyolefin master batch. The functional master batch is produced by liquid phase, melt phase, or solid phase reaction after mixing the polyolefin resin, polyamine and guanidine salt oligomer, olefin monomer and initiator. The molecular structure of functional polyolefin master batch is shown below: wherein R is a polyamine and guanidine salt oligomer bonded onto polyolefin molecular chain by covalence bond, while S is one selected from hydrogen, chlorine, methyl, or phenyl group. Blending mentioned functional master batch with the corresponding polyolefin, the various antimicrobe products, such as fibers, film, pipe and other plastic articles can be obtained. Besides endowing products with excellent permanent antimicrobe property, it also provides fibers with good-dyeable and antistatic ability and bumpers with easy-paintable ability.

  • Publication number: 20080139441
    Abstract: Polysaccharide fibres, such as cellulose or starch, modified by grafting an amino-containing antimicrobial polymer (ACP) onto the fibres or starch using a co-polymerization reaction, exhibits high antimicrobial activity. For example, the presence of 1.0% by weight grafted polymer in the cellulose fibres or starch fibres results in excellent antimicrobial activity (over 99% inhibition). The application further discloses that including triclosan or butylparaben into a novel cationic ?-cyclodextrin polymer or nanocapsule yields a bacteriostat.
