  • Patent number: 12110624
    Abstract: A sewing machine includes a main body and a quick release needle plate module. The main body includes a base seat having an inner frame, and an outer case that is mounted to the inner frame and that defines an accommodating compartment. The quick release needle plate module includes a catch member, and a needle plate that covers the accommodating compartment, that is detachably pivoted to a rear section of the inner frame, and that engages the catch member. The quick release needle plate module further includes a press member inserted through the outer case and the inner frame, and operable to push the catch member to disengage the catch member. The needle plate has a plate body that covers the accommodating compartment, and a resilient member mounted between the inner frame and the plate body for driving pivot action of the plate body away from the inner frame.

  • Patent number: 10450603
    Abstract: The fluorescence detection device includes an illumination module and a detection module. The illumination module includes a light source and a first filter. The light source is configured with the first filter to pass a first light beam at a first particular bandwidth along a first optical axis for exciting a targeted fluorescent probe and generating a fluorescent light. The detection module includes a second filter and a photo-detector. The second filter receives the fluorescent light and passes a second light beam at a second particular bandwidth along a second optical axis. The photo-detector receives the second light beam at the second particular bandwidth and converts the second light beam at the second particular bandwidth to an electrical signal. The first optical axis is tilted from the second optical axis at a specific angle ranged from 4.5 degrees to 9.5 degrees.
