Abstract: A blood detection method and a blood detection device are disclosed. When a count number of platelet in a blood sample is less than a predetermined value, a detection solution of the blood sample is prepared. A cell statistical amount of the detection solution of the blood sample is increased to obtain the platelet detection result. The cell statistics amount of the detection solution of the blood sample may be increased in an impedance detection area to perform PLT-I detection, or in an RET detection area; or performing both of RET detection and PLT-O detection simultaneously. Thus, the accuracy of platelet detection can be improved when the number of platelets in the blood sample is low.

Abstract: The invention relates to method for displaying the search results of the component e-commerce platform by classification. The method comprises the following steps of: S1, receiving a search keyword and sending the search keyword to a website server; S2, inquiring to obtain the data files containing the search keywords and gathering the data files with the same type labels into an aggregation column; S3, calculating the file weight value of each data file and sorting all the data files in each aggregation column from large to small according to the file weight value; S4, taking the maximum file weight value in each aggregation column as a column item weight value of the aggregation column, and all the aggregation column are sorted from large to small according to the column item weight values; and S5, sending the query results of the classification and sorting to a webpage for display by the website server.

Abstract: A camera module of reduced overall height includes multiple electronic components embedded in a PCB, multiple first holes defined on the PCB, each first hole enables a connection with one electronic component. A sensor chip is attached to the PCB by anisotropic conductive adhesive, multiple conductive balls on the sensor chip enter the multiple first holes and connect with the multiple electronic components. The embedded electronic components and the PCB form an integrated and single structure, avoiding multiple installations of electronic components one by one into the board and simplifying the manufacturing process of the camera module. The multiple conductive balls sinking into the multiple first holes reduce overall size of the camera module. A method for manufacturing the camera is also disclosed.

Abstract: An automatic leveling device of a 3D printer, and a 3D printer is provided. The automatic leveling device includes a photoelectric switch, an electromagnetic assembly and a probe assembly. The photoelectric switch is arranged in a housing and defines a photosensitive groove. The electromagnetic assembly is arranged in the housing and defines a sliding hole. The probe assembly is slidably engaged in the sliding hole, and an end of the probe assembly is engaged in the photosensitive groove. The electromagnetic assembly is capable of driving the probe assembly to make the end of the probe assembly move out of the photosensitive groove. The automatic leveling device has the advantages of simple structure, low manufacturing difficulty, low production cost, simple and stable leveling mode, high detection repetition accuracy and no complex circuit and software cooperation.

Abstract: A synchronous rectification control circuit has a turn-on detection circuit. The turn-on detection circuit has a slope detection circuit and a threshold generation circuit. The slope detection circuit generates a slope representation signal representing a falling slope of the detection signal. The threshold generation circuit generates a threshold signal by selecting one of threshold reference signals according to a driving signal. The turn-on detection circuit generates a comparison result signal by comparing the slope representation signal and the threshold signal for controlling the switch state of the synchronous rectification transistor.

Abstract: An image coloring method includes: acquiring first color a priori information about an image-to-be-colored; transforming the first color a priori information to obtain second color a priori information aligned with the image-to-be-colored; downsampling the image-to-be-colored to obtain a first image feature; performing modulation coloring processing on the first image feature based on the second color a priori information to obtain a second image feature; and upsampling the second image feature based on the second color a priori information to obtain a first colored image, where the first colored image is aligned with the image-to-be-colored.
