Abstract: A cantilevered rotatable carcass carrier includes a main carcass and two secondary carcasses. The two secondary carcasses are pivotally connected to two sides of the main carcass through two first cantilevers. The secondary carcasses are further pivotally connected with second cantilevers. The secondary carcasses further pivotally connected with an airtight cabin through the second cantilevers. By turning the secondary carcasses, the airtight cabin can be located under the main carcass to form a submarine mode or located above the main carcass to form a watch mode, broadening the recreation space on the water, such that the recreation space on the water is not limited to the type of two-dimensional space on the water. The present invention provides a novel water recreational carrier for the demands of different situations.

Abstract: A water craft able to offer fast rescue includes a water craft provided with a pressurization pump and a high pressure air reservoir to have air pressurized and poured into the high pressure air reservoir and stored therein. The water craft is formed with a concealed storage space having an uninflated rescue device received therein. The rescue device communicates with the high pressure air reservoir so that the rescue device can be inflated via the high pressure air reservoir. Thus, before inflated, the rescue device can be entirely received in the concealed storage space, letting the water craft have good maneuverability and, after inflated, the rescue device will be ejected out of the concealed storage space for carrying many persons thereon, thus advantageous to carry out rescue mission.

Abstract: There is disclosed a programmable memory emulator capable of emulating unspecified memory devices. A smart I/O interface is provided in the emulator for being programmed to conform to the interface specifications of different memory devices. An emulation look-ahead memory is employed to replace conventional two-port RAM. Furthermore, the memory of a host is utilized to emulate the functionality of system memory. Thus, the memory emulator is able to emulate various kinds of memory device, and the memory space is only restricted by the host.
