  • Patent number: 8612507
    Abstract: A computing device includes: a deciding unit which, in computation of values of nodes on a lattice in a direction where a value of m representing a horizontal axis coordinate of the lattice increases, decides dummy nodes to be added to m=n?1, so as to enable values of nodes on m=n to be calculated by adding the dummy nodes to m=n?1 and executing a vector operation through the use of the SIMD function by using values of nodes on m=n?1 and values of the added dummy nodes; an adding unit adding the dummy nodes decided by the deciding unit to m=n?1; and a calculating unit calculating the values of the nodes present on m=n by executing the vector operation through the use of the SIMD function by using the values of the nodes on m=n?1 and the values of the dummy nodes added by the adding unit.

  • Patent number: 8597952
    Abstract: A method for analyzing platelets is described. In the method, a measurement sample is prepared by mixing a sample and a dye for staining platelets. The dye is selected from the group consisting of Capri blue, Nile blue and brilliant cresyl blue. Upon irradiating cells in the measurement sample with light, scattered light and fluorescence emitted from the cells are measured. The platelets are detected on the basis of the scattered light and the fluorescence. A reagent kit and a reagent are also described.
