  • Patent number: 12216115
    Abstract: The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

  • Patent number: 10950267
    Abstract: The present disclosure relates to a magnetic recording medium for a magnetic media drive. Absorbing smears can develop on magnetic recording heads during operation. The absorbing smears lead to shortened drive lifetime. Transparent smears, on the other hand, do not have as deleterious of an impact on drive lifetime as compared to absorbing smears. By doping the medium with a dopant that can lead to development of transparent smears, the formation of absorbing smears can be reduced or even eliminated, which leads to a longer drive lifetime. The dopant can be disposed in the capping layer of the medium or in the absorbing overcoat layer. The dopant will migrate through the medium to the top surface of the medium during operation. From the top surface of the medium, the dopant will deposit on the magnetic head and form a transparent smear.

  • Patent number: 8771484
    Abstract: The present invention discloses a device for detecting blood cells and a microscopic hole sensor assembly thereof. The device includes a microscopic hole sensor assembly positioned between a front pool and a back pool. The microscopic hole sensor assembly further includes a microscopic hole plate with a microscopic hole positioned thereon for communicating the front pool and the back pool. The end surface of the inlet is a flow-guiding surface gradually narrowing from the front pool to the back pool. The end surface of the outlet is a downstream surface gradually distending and extending towards the back pool. A straight effective orifice area is formed connecting the ends of the flow-guiding surface and the downstream surface.
