  • Patent number: 10069253
    Abstract: The present disclosure provides a filter and a radio frequency coaxial connector, to implement fast blind-mate of various signal ports. The filter includes: a filter cavity body and a coaxial connection component. The coaxial connection component is embedded in the filter cavity body in a self-clinching manner. The coaxial connection component includes a socket outer conductor and a main rod. The main rod penetrates the socket outer conductor, and one end of the main rod is connected to a signal end disposed in the filter cavity body. The coaxial connection component is in socket joint with a radio frequency coaxial connector by using the socket outer conductor, and the coaxial connection component matches the radio frequency coaxial connector.

  • Patent number: 9970857
    Abstract: This disclosure provides automatic compensation methods, corresponding devices and a corresponding flow cytometer. The automatic compensation method includes: determining a base cell population and a reference cell population in the cell populations according to positions of the cell populations in a dot plot that needs to be compensated, where the base cell population is a double negative cell population and the reference cell population is a single positive cell population adjacent to the base cell population in a compensating direction (S10); calculating automatically a compensation value through a progressive approximation algorithm according to a position of the base cell population, and updating the dot plot with the compensation value, so that the position difference between the reference cell population and the base cell population both in the dot plot in the compensating direction is within a predetermined range (S16).

  • Patent number: 9632086
    Abstract: A method and kit for determining antibody sensitivity and quality of a clone cell stain. The method comprises: obtaining a solid-phase carrier, cells and an antibody; adsorbing the antibody on the solid-phase carrier; incubating the cells and the antibody; preserving cells bound with the antibody; and dyeing and counting the cells bound with the antibody, so as to determine the antibody sensitivity or the quality of the clone cell stain based on the cell count. The kit comprises components used in the method.

  • Patent number: 9612180
    Abstract: A dyeing device of a smear machine may include a dyeing tank, a transmission mechanism and a work position set in an enclosed delivery channel of the transmission mechanism. The work position may include a blocking and separating mechanism, a reagent supplying and discharging mechanism, and a driving mechanism for driving the blocking and separating mechanism. The blocking and separating mechanism can operate for blocking a dyeing tank to be treated in a current work position, separating a treated dyeing tank and transmitting a separated dyeing tank to a next work position along the enclosed delivery channel. The reagent supplying and discharging mechanism can inject and/or discharge reagent into/from the dyeing tank. Various embodiments of this disclosure can transmit the dyeing tank within the enclosed transmission channel, block and separate the dyeing tank in the work position, and inject/discharge the dyeing solution into/from the dyeing tank as needed.
