  • Publication number: 20150012060
    Abstract: The remote electrical treatment system contains an authentication server, a prescription server, a backup server, a prescription access device, and an electrical treatment device. A user can requests an electrical treatment prescription anywhere and anytime from the authentication server through the prescription access device, and conducts electrical treatment either when the user is on-lined or off-lined. The present invention therefore frees the user from time and space constraints, provides greater usage flexibility and application support, thereby achieving superior treatment density and enhanced medical quality.

  • Patent number: 6279141
    Abstract: A preburn-in DRAM module circuit board is provided, which allows a plurality of DRAM modules to be constructed directly thereon, and which can be directly connected to a large burn-in oven so as to perform a burn-in process concurrently on the DRAM modules mounted thereon to check for any defected IC chips that are to be reworked. After the burn-in process, each of the DRAM modules can be cut apart from the circuit board to serve as a single memory module. The preburn-in DRAM module circuit board allows the manufacturing process for the DRAM modules to be reduced in schedule and manufacturing cost. Material cost can also be saved since the burn-in circuit and the module circuit are arranged on the same circuit board.
