  • Patent number: 12235180
    Abstract: The present invention discloses a phase alignment system and method of oscillating mirror. The present invention utilizes the reciprocating scanning symmetry feature of the simple harmonic oscillation motion of the oscillating mirror to construct scanning pattern data with complementary pixel brightness and darkness. When the phase difference parameter applied by the scan controller is consistent with the actual phase of simple harmonic oscillation of the oscillating mirror, the scanning pattern data with complementary pixel brightness and darkness and the reciprocating motion of the oscillating mirror are accurately matched, and a perfect stitched continuous scanning line with uniform brightness is obtained on the projection plane, thereby achieving the effect of being clearly distinguishable, easy to detect, and convenient for alignment operation.

  • 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.
