  • Patent number: 6776160
    Abstract: An intake valve includes a bladder having a face piece coupled to one end and an opening formed in the other end, a cover attached to the other end of the bladder and having a port coupled to an air reservoir and having a hub coupled to a container, which may be used for pumping air into the bladder when the air in the air reservoir has been consumed. The cover has a check valve for air to flow into the cover when the container is expanded, and for pumping air into the bladder when the container is squeezed. Another check valve may be used for outward flowing of excess air.

  • Publication number: 20020133451
    Abstract: A dynamic price changing web marketing system, which comprises a commodity database, a commodity data providing module, and a trade processing module. The commodity database stores at least one commodity datum. The commodity providing module provides commodity data in a specific format. The trade processing module receives consumer's order for purchasing commodities. It is further characterized in that it contains a dynamic price changing module that gradually lowers the commodity price from an initial price. The commodity data providing module immediately provides the lowered price to the consumer. The trade processing module receives the consumer's order for purchasing the commodity when the price is lowered to a specific value. The invention also discloses a corresponding dynamic price changing web marketing method.

  • Publication number: 20020111871
    Abstract: A method for implementing contract stores on a network. This method determines whether a consumer is a member of a specific group according to the data entered by the consumer when he logs in. When the consumer is a member of a specific group, he is viewed as a special member and a special price is provided when he quotes the price. The invention also provides a system for implementing this method.

  • Publication number: 20020065705
    Abstract: The invention relates to a method for modifying questionnaire contents, comprising a recording procedure, an analysis procedure, and a modification procedure. The method is applied to a questionnaire with a plurality of questions, each of which having a plurality of options. The recording procedure stores in a questionnaire database the selection results of all questions obtained from the investigation using the questionnaire beforehand. The analysis procedure analyzes the selection ratios of all options according to the selection results. The modification procedure deletes a particular question from the questionnaire when the selection ratio of an option in the question is higher than a predetermined value. The specification also discloses a corresponding system of modifying questionnaire contents.

  • Patent number: 5876942
    Abstract: A rapid, highly reproducible and sensitive technique has been successfully developed for sexing the cow embryos, by method of polymerase chain reaction (PCR) against the amelogenin (bAML) genes located on both X- and Y-chromosomes of the Holstein dairy cattle. Results from DNA sequence analysis showed that there was only 45% homology between the intron 5 of AMLX and AMLY genes. Based on these sequences a pair of sex-specific primers, pbAML5XY(+) and pbAML5XY (-),were designed allowing to amplify a single fragment of 476-bp from the female cattle and two fragments of 476-bp and 341-bp from the male ones, respectively. The most important feature is that the precise sensitivity of sex-determination was confirmed to be reached as minimum template as trace amount of genomic DNA content in either a single lymphocyte or a single blastomere isolated from cow embryo at day-6 to day-7.
