  • Patent number: 11635437
    Abstract: Disclosed herein is a method for verifying the primary structure of a protein through comparative analyses between ion clusters observed in mass spectra and a series of simulated ion clusters deduced from its putative chemical formula. The method comprises the steps of: preparing a protein sample for mass spectrometric analyses; collecting mass spectra of the protein sample; obtaining master ion cluster from a plurality of ion clusters in the mass spectra; producing a series of simulated ion clusters according to the chemical formula of the protein; finding the best fit for the master ion cluster among the series of simulated ion clusters; and verifying if said best-fit simulated ion cluster corresponds to the chemical formula of the protein.

  • Publication number: 20180157891
    Abstract: A fingerprint flash drive includes a circuit board, an enclosure and a fingerprint recognizer. The enclosure encloses the circuit board. An insertion direction of the fingerprint flash drive is defined as a front-to-rear direction. The enclosure has a top surface extending along the insertion direction of the fingerprint flash drive, and a front surface connected with a front edge of the top surface. The front surface and the top surface of the enclosure are noncoplanar. A rear end of the enclosure cooperates with the circuit board to form a plug. The fingerprint recognizer is electrically connected with the circuit board and fastened to the front surface of the enclosure. A front surface of the fingerprint recognizer is exposed outside.

  • Publication number: 20150241932
    Abstract: A storing device includes a storing unit, a first cap, a second cap and a hollow housing. The storing unit has a storing module and a processing module which are disposed in the storing unit. The storing unit includes a first inserting port and a second inserting port which are oppositely positioned in two opposite sides of the storing unit. The first cap removably covers the first inserting port of the storing unit. The second cap removably covers the second inserting port of the storing unit. The hollow housing sheathes the storing unit therein and is located between the first cap and the second cap. The first inserting port and the second inserting port oppositely project beyond two end faces of the hollow housing. The hollow housing has a first connecting arm connected to the first cap and a second connecting arm connected to the second cap.
