  • Patent number: 7287052
    Abstract: A condition on a client that is communicating with a server is determined by issuing a challenge to the client, causing the client to produce a response indicative of the condition. The server compares the response to an expected response to determine if the condition is as expected, and if not, takes appropriate action, such as terminating the connection with the client. The challenge preferably includes parameters and a code segment that causes the client to produce the response by executing the code segment. The code segment could perform a one-way hashing algorithm of a portion of memory indicated in the parameters. The server can thus determine if the client is using a modified basic input output system, modified software, pirated software, or whether other conditions exist on the client. The challenge can be changed to prevent the client from returning a false, predetermined response to the challenge.

  • Patent number: 7278126
    Abstract: To fix hold time violations, timing analysis is initially performed on a circuit design for each set of timing constraints to determine a setup slack and a hold slack for each signal path for that set of timing constraints. The slack for a signal path indicates the amount of timing margin or the amount of timing violation for that signal path. Signal paths with hold time violations (or “hold paths”) are identified and retained, and other signal paths without hold time violations are discarded. For each hold path, signal paths with at least one node in common with the hold path (or “related setup paths”) are identified and retained. Related setup paths with large setup slacks may be pruned. The hold time violations for the hold paths are then fixed based on the hold slacks for the hold paths and the setup slacks for the related setup paths.

  • Publication number: 20070171278
    Abstract: A multimedia greeting card comprises a speaker, a memory unit, a power supply, a controller, a button, a rectangular frame and a paperboard having multiple folding pages and wrapping around the frame. The frame has multiple holders for holding the speaker, the button, and a circuit board on which the memory unit, the power supply and the controller are installed. An outer folding page of the paperboard has one set of speaker openings and a button opening faced to the speaker and the button, respectively. An adhesive can be alternatively used to obtain secure attachment of the paperboard with the frame. The multimedia greeting card further comprises an LCD device held on a holder of the frame, and the paperboard has a LCD window faced to the LCD device. When pressing the button, it playbacks multimedia files stored in the memory unit through the speaker and the LCD device.

  • Patent number: 7218739
    Abstract: A console-based multi-user authentication process allows multiple users of a game console to be authenticated together in a single request/reply exchange with an authentication entity. The results of which is the possession of a single ticket that can be used to prove authenticity of multiple authentication principals to one or more online services. Also described is a handshake process that can be used to initially establish an authentication account for each game console, in which the account creation server can trust that a genuine game console is making the request.

  • Patent number: 7203835
    Abstract: An architecture is described to manufacture console-based gaming systems in a manner that allows them to be authenticated to a remote entity for online participation. The architecture involves placing pre-established secrets on the game console during console manufacturing that may be subsequently used to guarantee the authenticity of the game console during registration time.

  • Publication number: 20070023335
    Abstract: A cooling water recycling filter comprises a supersonic and electromagnetic wave limescale processor installed inside a main water recycling system of water storage tank and a sub water recycling system installed outside a main water recycling system. The sub water recycling system comprises a water quality control unit, a limescale processor unit, a limescale separation and filter unit and a high level oxidization and processing unit. An electric conductivity sensor, a PH value sensor, and an ORP oxidization and reduction potential meter of water quality control unit are used to measure the values of water quality. A limescale processor and impurities separator is used to filter impurities of the cooling water. After the cooling water is filtered precisely by the limescale separation and filter unit, the cooling water is sterilized by a copper and silver sterilizing and algae-killing unit of a sterilization unit.

  • Patent number: 6907522
    Abstract: Machine instructions comprising a bootstrap code are buried within a critical component of an electronic game console where they cannot readily be accessed or modified. A preloader portion in a read only memory (ROM) is hashed by the bootstrap code and the result is compared to an expected hash value maintained in the bootstrap code. Further verification of the boot-up process is carried out by the preloader, which hashes the code in ROM to obtain a hash value for the code. The result is verified against a digital signature value that defines an expected value for this hash. Failure to obtain any expected result terminates the boot-up process. Since the bootstrap code confirms the preloader, and the preloader confirms the remainder of the code in ROM, this technique is useful for ensuring that the code used for booting up the device has not been modified or replaced.

  • Publication number: 20040224771
    Abstract: Controlling access to secure data and services by versatile computers outside a secure environment, which communicates with limited dedicated devices such as game consoles, over a secure network such as a virtual private network. The versatile computing devices obtain access over an insecure network, such as the Internet, through a trusted partner Web site that authenticates users of the site and relays requests to the secure environment. The Web site uses a certificate for a predefined level of secure access to the secure environment. A link is established between a user's Web ID authenticated by the Web site and a gamer tag used within the secure environment. Access is limited as a function of the Web ID, gamer tag, and a Web site partner ID. A Web cache stores and provides some secure data, minimizing disruption to the secure environment's primary function to service the dedicated devices.
