Abstract: An advanced wireless projector presentation system with network management control includes a LAN; an intranet wireless router connected to the LAN; an administrator computer connected to the LAN via the router; and multiple workgroups, each of which includes at least one projector and at least one presenter computer. The projectors each is connected to the LAN via an RJ45 network cable, and allows the administrator computer to access the projectors for presenting images and to control the on, off, and standby of the projectors. The presenter computers are connected to the LAN via the router, so as to use the projectors in the same workgroup to project images. Meanwhile, the administrator computer can also directly control the projectors in every workgroup. Therefore, the projector presentation system can be conveniently used in a wide working environment through good network management control without the need of complicated wiring.

Abstract: The preferred embodiment the invention presents pertains to a type of high-quality, non-flickering three-dimensional image projection method and its system, which mainly entails integrating a digital micromirror device (DMD) capable of processing 120 frames per second (120 fps) and a 120 fps three-dimensional analogical or digital image content to form a single surface DMD digital image projector for achieving a realistic, high-quality, non-flickering three-dimensional image viewing.

Abstract: A monitor includes a display mechanism having a display screen located on a front side thereof, and a video retrieving unit and an audio retrieving unit located at predetermined positions in the vicinity of the display screen; an adjusting mechanism connected to and located behind the display mechanism, and including a rotating unit connected to a rear lower portion of the display mechanism, and an elevating unit connected at an upper end to the rotating unit; and abase being fixedly connected to a lower end of the adjusting mechanism and provided at a bottom surface with a rotary disc. With these arrangements, the video and audio retrieving units of the display mechanism may be adjusted to a desired vertical height, inclination angle, and/or horizontal angle via the adjusting mechanism and the rotary disc of the base.
