  • Publication number: 20060018314
    Abstract: The present invention is to provide a method of downloading data from a PC to a PHS or vice versa, which comprises the steps of commanding a PC to edit data (e.g., phonebook, picture, or ring data) by a PHS, sending the edited data complying with the data requirements of the PHS to a data packet sending mechanism of the PC, and dividing the data into a plurality of data packets, sequentially sending the data packets to the PHS via a transfer interface of the PC, assembling the data packets for verification and storing the data packets in a corresponding area of the PHS.

  • Patent number: 6869771
    Abstract: A method for distributing an equal volume of attached confluent living cells in each well of a multi-well plate used in a bioassay, comprising the following steps: (a) growing attached living cells on a medium until the cells are confluent; (b) treating the attached confluent living cells with an enzyme solution, whereby the solution and the attached confluent living cells make a cell suspension; (c) filtering the cell suspension with a filter; (d) collecting a cell suspension filtrate containing uniformly distributed attached confluent living cells therein; and (e) distributing an equal volume of the cell suspension filtrate into wells of a plate whereby each well has an equal volume of cells for use in any bioassay.

  • Patent number: 6429021
    Abstract: The present invention provides an assay for detecting the presence of an array or a profile of antioxidant activity in any sources or products. In particular, the invention provides a method in which a sample is extracted with a polar, a non-polar and a semi-polar solvent to obtain three extracts; the extracts are chromatographed to get a chemical profile; and the profile is analyzed to determine the presence of antioxidants by directly reacting to a free-radical.
