Abstract: An electronic package and a manufacturing method thereof are provided, in which an electronic element stacking structure is disposed on a carrier structure to integrate multiple chips into a single package, so that the electronic package can meet with the requirements of miniaturization without increasing the layout area of the carrier structure.

Abstract: A method for analyzing abnormal network behaviors and isolating computer virus attacks comprises network equipments controlled by an automatic program so as to have a serious of processes of a packet analyzing, an identity locking and an instant isolating. By using a network monitoring module or/and a network identity module involved in the automatic program to simultaneously deal with the processes of the packet analyzing and the identity locking, and then by using an automatic locking module also involved in the automatic program to execute the process of the instant isolating, the viruses are appropriately isolated and then antivirus softwares scan the infected computer so as to have a problem solving, thereby obtaining a restoring.

Abstract: A height adjusting device for a chair consists of an inner tube having a top end fixedly connected to a chair seat and a bottom end fixedly connecting with a bushing, a positioning tube extending upwardly from a chair base, having an upper end mounted with a sleeve for receiving the inner tube and a base plate defining a plurality of downward protrusions, a screw having a threaded upper section for threadedly engaging with the bushing and a reduced lower section defining an annular stepped edge and a bottom end extending through the base plate to fixedly attach with an engaging member defining a plurality of upward protrusions for releasably engaging with the downward protrusions of the base plate, the threaded upper section of the screw defining a top projection and a bottom projection for limiting the traveling of the bushing therealong, a spring and a bearing assembly being mounted around the reduced lower section of the screw and located between the base plate and the threaded upper section of the screw.
