Abstract: A combinable nucleic acid pre-processing apparatus includes a sample transfer chamber transferring a sample from a sampling tube to a nucleic acid extraction kit, a nucleic acid extraction chamber performing a nucleic acid extraction of the sample in the nucleic acid extraction kit for obtaining a nucleic acid extract, an assay setup chamber preparing reagents and transferring reagents and the nucleic acid extract to an assay plate, and at least two bridging modules respectively disposed between the sample transfer chamber and the nucleic acid extraction chamber and between the nucleic acid extraction chamber and the assay setup chamber. The sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber are separated and operated independently. Three chambers are connected through the bridging modules, so the nucleic acid extraction kit can be sequentially moved in the sample transfer chamber, the nucleic acid extraction chamber and the assay setup chamber.

Abstract: The present invention discloses an interactive projection system including a pointing device and a projector. The pointing device is used to generate a light spot. The projector includes a projecting module, an image capturing module, and a processing module, and the projector includes a built-in operating system. The operating system includes a plurality of applications with graphical user interfaces. The projecting module projects a projected image being present of the operating system onto a screen. The image capturing module captures an image generated by projecting the light spot onto the screen. The processing module calculates a coordinate of the light spot according to the above-mentioned image, and determines whether the light spot has stayed on the graphical user interface associated with one of the applications on the projection screen, so as to execute the application corresponding to the light spot.

Abstract: An orientation-adjusting device for adjusting an orientation of a wireless transceiver is disclosed. The transceiver is mounted in a PC via a USB adapter. The orientation-adjusting device includes a first housing for accommodating therein the transceiver, a second housing pivotally connected to the first housing to allow the first housing to rotate in a first direction relative thereto, and a third housing for accommodating therein the USB adapter, pivotally connected to the second housing to allow the second housing to rotate in a second direction relative thereto. By this way, the orientation of the transceiver accommodated in the first housing can be adjusted in two dimensions to perform communication functions well even when it is fitted into a confined space in the PC.
