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: A unique call mapping and routing device combines Voice over Internet protocol (VoIP) and public switched telephone network (PSTN) technologies such that mobile device users are able to dial international calls that are automatically and transparently directed through local access numbers using the mobile carrier PSTN network.

Abstract: A machine tool includes a machine frame, a worktable, and a spindle unit. The worktable is movable on the machine frame along a first horizontal direction, a second horizontal direction perpendicular to the first horizontal direction, and a vertical direction. The spindle unit is movable on the machine frame along the vertical direction.
