  • Patent number: 11959911
    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.

  • Publication number: 20230113709
    Abstract: A transmitter circuit, an optical module, and a communications device is disclosed. A transmitter circuit includes a driver and a directly modulated laser DML. A positive electrode of the driver is connected to a positive electrode of the DML, a negative electrode of the DML is connected to a voltage terminal, and the negative electrode of the DML is connected to a ground terminal through a capacitor. The driver is configured to generate a drive current based on an input signal, and output the drive current to the DML through the positive electrode of the driver. The DML inputs a first part of current of the drive current to the ground terminal through the capacitor, and the DML inputs a second part of current of the drive current to the voltage terminal.

  • Patent number: 10685925
    Abstract: Systems and methods that facilitate resistance and capacitance balancing are presented. In one embodiment, a system comprises: a plurality of ground lines configured to ground components; and a plurality of signal bus lines interleaved with the plurality of ground lines, wherein the interleaving is configured so that plurality of signal bus lines and plurality of ground lines are substantially evenly spaced and the plurality of signal bus lines convey a respective plurality of signals have similar resistance and capacitance constants that are balanced. The plurality of signals can see a substantially equal amount ground surface and have similar amounts of capacitance. The plurality of signal bus lines can have similar cross sections and lengths with similar resistances. The plurality of signal bus lines interleaved with the plurality of ground lines can be included in a two copper layer interposer design with one redistribution layer (RDL).
