Abstract: A high-throughput automated preprocessing method and a system are applied to a nucleic acid preprocessing apparatus including a control system, a sample transfer area, a nucleic acid extraction area, and a reagent setup area. The control system includes a user interface and guides a user to set up on the user interface. In the sample transfer area, the method includes steps of: a user selecting a sampling tube type, a test protocol and an extraction protocol on the user interface, and the control system performing a sample transfer task. In the nucleic acid extraction area, the method includes steps of: the control system performing a nucleic acid extraction task based on the selected extraction protocol. In the reagent setup area, the method includes steps of: the control system performing a reagent deployment task based on the selected test protocol, and the control system performing a nucleic acid transfer task.

Abstract: There is provided an optical engine assembly including a bench, at least one optoelectronic unit, at least one optical waveguide and a mount. At least one support groove and a positioning groove are formed on the bench and connected with each other, and the support groove perpendicularly extends outward from one side of the positioning groove. The optoelectronic unit is disposed at the other side of the positioning groove and aligned with the support groove. One end of the optical waveguide is placed inside the support groove and the other end thereof penetrates through at least one through hole of the mount.

Abstract: A frame includes a plurality of L-shaped elbow members and tubes. Each elbow member includes two extension tubes and each extension tube has an open end and a hole is defined through a wall proximate to the open end. Each tube includes two open ends so as to be inserted into the open ends of the extension tubes of the elbow members. Each open end of each of the tubes has a hole defined through a wall proximate to the open ends. A C-shaped connection member is biased in the open end of each tube and has a protrusion which is inserted in the aligned holes of the tubes and the extension tubes.

Abstract: A coupler for a sport practice net rack includes a first angular tube having a first flat section and a first angular section, and a second angular tube pivotally mounted on the first angular tube and having a second flat section and a second angular section. The second angular section of the second angular tube is detachably received in the first angular section of the first angular tube.
