Abstract: A support pad comprises a first surface layer, a second surface layer and an airbag structure. The first surface layer is disposed on the first surface of the support pad. The second surface layer is disposed on the second surface of the support pad and connected to the first surface layer. An edge of the first surface layer is connected to an edge of the second surface layer to cover the airbag structure. The airbag structure has a plurality of hollowed portions and a first connecting portion of the first surface layer is connected to a second connecting portion of the second surface layer through a space provided by the hollowed portions.

Abstract: A hospital bed comprises gas mattress units, connecting pipe devices and a gas supplying-releasing device. The gas mattress units each have an inner layer and an outer layer. The inner layer is an airbag. The outer layer is a laminated fabric. The laminated fabric encloses the airbag. The airbag internally defines a first gas receiving space. A second gas receiving space is defined between the laminated fabric and the airbag. The connecting pipe devices and the gas supplying-releasing device are in communication with the gas mattress units, allowing a gas to be introduced into and released from the first gas receiving space. The first and second gas receiving spaces enable the hospital bed to bear high internal pressure and thus be durable, thereby lessening the durability requirement of the laminated fabric.

Abstract: In a method for testing a redundant array of independent disks (RAID) of a computer, the RAID includes two or more hard disk drives. A RAID volume is created for the RAID. One of the hard disk drives in the RAID is disabled while the RAID volume is in an optimal state. The RAID volume is in a degraded state when one of the hard disk drives in the RAID is disabled. The disabled hard disk drive in the RAID is then enabled while the RAID volume is in the degraded state. Then an attempt to rebuild the RAID volume is made. The RAID works normally once each of the hard disk drives in the RAID is disabled and enabled, and the RAID volume is successfully rebuilt after each enablement and the optimal state is achieved.

Abstract: A tent with improved structure is disclosed. The present invention includes a tent body with several covering portions, several sleeve pipes disposed among the covering portions, an opening disposed in one of the covering portions and a supporting structure with a connecting portion comprises a main encapsulation and several complementary encapsulations. The encapsulations are worn through the sleeve pipes, and every complementary encapsulation comprises an opening end and a closing end. The opening ends of the complementary encapsulations are connected respectively to the connecting portion of the main encapsulation, wherein6 an air hole is disposed in one of the encapsulations. A sleeve bag is combined from a plurality of sleeve tubes and it is utilized to slide onto the supporting structure, the connecting portion of the main encapsulation and the complementary encapsulations in order to increase the reliability and toughness of the connecting portions of the tent structure.
