Abstract: A detection device to detect analytes includes a sensor array and a controller. The sensor array includes a plurality of sensors, the plurality of sensors includes a sensing element, a heating element, and a lighting element. The controller is communicatively coupled to the sensor array, the heating element, and the lighting element, and configured to adjust at least one of the heating element or the lighting element based on a temperature profile of the heating element and an illumination profile of the lighting element.

Abstract: A rivet with improved structure for forming flat-bottom riveting of plates, which comprises a rivet cover, a rivet shoulder and a rivet body; specifically, the rivet cover is provided with a torque transmission structure and a positioning structure for driving the rivet to rotate; the rivet body comprises an inner cavity of the rivet body, an outer wall of the rivet body and an end of the rivet body; with the present invention, the bottom surface of the joint can be flush with the surface of the connected plates, which facilitates the subsequent processing of the coverage on the bottom surface, reduces the wind resistance coefficient of the joint, and broadens the application range of the process.
