  • Patent number: 8213999
    Abstract: A controlling method and a controlling system for a handheld communication device are provided. In the present method, a tilting state of the handheld communication device is detected by using a G-sensor when a notice is activated. Then, whether the tilting state is changed from a face up state to a face down state is determined. The handheld communication device is controlled to perform a function when the tilting state is confirmed to be changed from the face up state to the face down state. Accordingly, the handheld communication device may be controlled to perform a function timely according to the positioned state of the device without going through complicated procedures, so as to provide a more intuitive and convenient way to control the handheld communication device.

  • Publication number: 20110299210
    Abstract: A serially connected surge suppression optimization device has an input terminal, an output terminal, a plurality of surge suppression units. The surge suppression units are serially mounted between the input terminal and the output terminal. Each surge suppression unit has at least one pair of parallel inductors and a plurality of surge absorption units respectively connected with one end of each of the pair of inductors. The pair of parallel inductors mounted in the surge suppression unit in a pre-stage and the surge suppression unit in a post-stage have different conductance values. Accordingly, the surge suppression optimization device connected in a path from which surges pass can significantly reduce energy of a surge flowing in and a residual surge voltage. The different conductance values of the surge suppression units in a pre-stage and a post-stage smoothen an intruding surge to secure better safety protection without abruptly generating a peak rise.

  • 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: 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.
