Abstract: A microfluidic chip capable of being used for capturing target particles, the chip comprising a convergence and shunt unit, the convergence and shunt unit being capable of converging target particles in a liquid sample to the centre of a liquid flow, and simultaneously splitting off a certain proportion of the liquid flow that does not contain target particles, thereby effectively reducing the flow and speed of the liquid flow inputted to the chip; when used for capturing target particles, the chip also comprises a capturing unit, and implements capture of the target particles by means of the capturing unit.

Abstract: A computing device is connected to a measurement machine. The measurement machine measures an object to obtain images of measured elements of the object by using a measurement program. The computing device divides the measurement program into two or more program segments. An icon for each program segment is generated according to a type of the program segment. The computing device generates a title state and an opened state for each program segment. If a program segment is in the title state, the icon, a name, and a first line of program codes of the program segment is displayed on an interface provided by the electronic device. If the program segment is in the opened state, the computing device displays all program codes of the program segment on the interface.

Abstract: A method of optimizing measurement paths analyzes one or more measurement points for each of the measurement elements of a product and generates relation arrays, each of the relation arrays storing the name and the one or more measurement points of one measurement element. The method selects a measurement point which is the nearest to the origin of an coordinate system of the product, computes distances between the measurement points from the selected measurement point using the relation arrays, and orders the measurement points according to the computed distances to generate a first ordered array. The method generates an optimal measurement path according to the first ordered array.

Abstract: In a method for extracting data of a product, an electronic design document related to the product and point cloud created using actual measurements of the product are received. The point cloud includes points of the product. The method aligns the curved surface of the product with the corresponding portion of the point cloud using a best-fit method, creates a maximum space box for a feature element of the product, and deletes points that are not within the maximum space box. According to an average distance between two neighboring points of the point cloud, the maximum space box can be divided into many small space boxes. Using the small space boxes, the points are filtered to form a feature element.

Abstract: A computing device is connected to a measurement machine to measure an object to obtain an image of measured elements of the object. The computing device generates a tree structure to display all of the measured elements. Icons at nodes of the tree structure are generated corresponding to the measured elements. If a cursor points to a particular node of the tree structure, the computing device determines a coordinate range in which the cursor falls. An icon corresponding to the node is determined as being the icon selected according to the range. The computing device displays a measurement program corresponding to the icon.

Abstract: In a computing device having a computerized method and a non-transitory storage medium, one or more highlighting modes are constructed, each of which defines which sections in a measuring program need to be highlighted. One of the highlighting modes is selected to highlight a measuring program in a particular way. Then, the highlighted measuring program is displayed on a display unit of the computing device.

Abstract: A method of optimizing measurement paths computes a minimum bounding box for the measurement elements on a product, and computes a capturing range of a lens of a measurement machine. The method divides the minimum bounding box into M*N partitions according to the capturing range, and assigns a number to each of the M*N partitions. The method puts the number of a partition which exclusively encloses a measurement element into a first array, and puts a number set that includes the numbers of the partitions which all enclose a measurement element into a second array, and lists the numbers of the partitions in order according to the first array and the second array to generate a measurement path.
