    Abstract: A method for multiple wireless power transfer, capable of transmitting power wirelessly to multiple receivers, by using a time division scheme, includes the steps of: (a) allotting exclusive power transmission time for at least one of the multiple receivers; and (b) transmitting the power wirelessly to each of the at least one of the receivers; wherein, during the exclusive power transmission time allotted to an i-th receiver, which is one of the multiple receivers, the receiving state of the i-th receiver is set to ON and those of the other receivers to OFF. In accordance with the present invention, the following effects can be achieved: the PTE of the multiple receivers may be increased and the PTE of each of the receivers may be kept similarly because the power is transmitted only to one receiver by using the time division scheme and thus interference among multiple receivers is eliminated.

  • Method for determining isotopic clusters and monoisotopic masses of polypeptides on mass spectra of complex polypeptide mixtures and computer-readable medium thereof
    Patent number: 8321153
    Abstract: Disclosed herein is a method of finding an isotopic cluster in a polypeptide and determining the monoisotopic mass of the cluster. The method comprises an algorithm for finding an isotopic cluster based on a probabilistic model, defined by each of peaks in the isotopic cluster, and determining the monoisotopic mass of the isotopic cluster. The probabilistic model of the isotopic cluster includes characteristic functions for mass, that is, a function of the ratio of two peak intensities, and a function of the product of two ratios obtained from three peaks. These characteristic functions for mass define the shape of peaks acceptable in an actual isotopic cluster for the mass of any isotopic cluster. The algorithm of finding the isotopic cluster based on the functions uses the characteristics to score the degree of the approximation of any isotopic cluster to the spectral shape of a theoretical cluster.
