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: The present invention relates to an enclosure that protects an operational data storage device (preferably a common disk data storage devices with an IDE interface) from fire, flood or other hazards. The preferred embodiment comprises an enclosure which is water resistant and heat transfer protected to preserve the disk data storage device in the event of disaster involving flood or fire. Insulation, including phase change materials, are used to maintain internal temperature during normal operation and during fire conditions, so as to meet the thermal test portion of UL 72, Class 125, one hour, and the disk data storage device temperature does not exceed 125° C. The enclosure of the preferred embodiment manages humidity to an internal RH at 80% or below.
