  • Patent number: 11961777
    Abstract: A package structure and a method of forming the same are provided. The package structure includes a first die, a second die, a first encapsulant, and a buffer layer. The first die and the second die are disposed side by side. The first encapsulant encapsulates the first die and the second die. The second die includes a die stack encapsulated by a second encapsulant encapsulating a die stack. The buffer layer is disposed between the first encapsulant and the second encapsulant and covers at least a sidewall of the second die and disposed between the first encapsulant and the second encapsulant. The buffer layer has a Young's modulus less than a Young's modulus of the first encapsulant and a Young's modulus of the second encapsulant.

  • Patent number: 9674299
    Abstract: A standby agent apparatus includes an interface and a standby agent controller. The interface is arranged for receiving at least first account information of a first system. The standby agent controller is coupled to the interface. When the first system is operating in a standby mode, the standby agent controller is arranged for keeping an account of the first system on-line in a first application server according to the received first account information of the first system. A connection handling method includes the following steps: receiving first account information of a first system; and when the first system is operating in a standby mode, keeping an account of the first system on-line in a first application server according to the received first account information of the first system.

  • Publication number: 20100042580
    Abstract: An object table is provided between a file system interface of a host and a multimedia device so that the host is capable of accessing objects stored in the multimedia device regardless of incompatibility between file formats respectively used in the file system and the multimedia device. At least one index of the stored object is stored in the object table. A file accessing architecture is constructed in the object table, where the file accessing architecture has at least one API recognizable for the file system interface. Therefore, the host is capable of accessing the objects stored in the multimedia device though the file system interface and the constructed file accessing architecture.
