  • Publication number: 20070101124
    Abstract: A method for retrieving an encrypted image of an object from a server site (22), caching it at a client site (24), and providing a decrypted image of the object to an authorized requester. When the requester is not authorized to access a decrypted image of the source data object, the encrypted image of the object cached at a client site (24) may be deleted, and/or, an authentication failure message may be sent to the server site, a security monitoring agency, the object's owner, and/or any other designated entity that can be contacted via any network accessible to the site that has detected the authentication failure.

  • Publication number: 20060168145
    Abstract: An upstream NDC site accesses a file that is alternatively accessible through at least two downstream NDC sites. The downstream NDC sites belong to a DDS domain which is a sub-domain of a domain at the upstream NDC site. Portal files at each downstream NDC store distinct network addresses for communicating with the different downstream NDC. A DDS domain manager at the upstream NDC site retrieves and uses a first network address for establishing data conduit between the upstream NDC site and one of the downstream NDC sites. If the upstream NDC site fails to receive a response to a message, that site uses a second network address for establishing a second data conduit between the upstream NDC site and the other downstream NDC site. In another aspect, the NDC sites ensure consistency between the file and the projected image of the file cached in the upstream NDC site.

  • Publication number: 20060053157
    Abstract: A hierarchical distributed search mechanism is integrated into a distributed file system. Traditional file system APIs (create, open, close, read, write, link, rename, delete, . . . ) and the over-the-wire protocols employed to project these APIs into remote client sites (CIFS, NFS, DDS, Appletalk) are extended to enable the dynamic creation of temporary directories containing links to objects identified by search engines (executing at sites “close” to “their” data) as meeting the search criteria specified by the first parameter of a search function call. The search function, derived from the standard file system API function create, is added to the file system API.

  • Publication number: 20060037008
    Abstract: In some embodiments, a user may select an elemental function such as read, write, or configuration from a graphical programming environment. A file may be created that instantiates functionality into a programmable hardware element to allow it to send a command across a serial protocol to peripheral interface circuitry and ultimately to peripheral chips (e.g., network chips on a CAN). The elemental node concept may be generic to any network chip because the node may contain only the general data of a packet (e.g., command type, value of data bytes, etc). The actual interface to a network chip may be handled inside the peripheral interface circuitry. The peripheral interface circuitry may have the details of the network chip in which it interfaces and may abstract details of the network chip from the target programmable hardware element through the serial protocol.

  • Patent number: 6968464
    Abstract: System and method for configuring a second system in a split bridge distributed environment. A host computer system (host) includes a memory operable to store host driver software (drivers) and a CPU operable to execute the drivers. A serial bus couples the host to the second system. The host saves configuration information for the second system. The second system receives user input requesting a power down condition. The drivers enters a quiescent state, generating an indication of a power down condition. The user powers down and reconfigures the second system. The host detects a link down condition between the host and the second system, and monitors a link status between the host and second system. The user powers up the second system. The host detects a link up condition, restores second system configuration, and performs a discovery process on the second system.

  • Publication number: 20050169491
    Abstract: Failure of the acoustic seal in “in-the-ear” hearing aid earmolds is a principle cause of acoustic feedback. The ongoing development of smaller hearing aids with close proximity between the hearing aid microphone and receiver mandates the highest quality earmold fit. This invention relates eliminates the feedback problem by placing a soft, pliant, and durable hydrogel coating (16) on the earmold (18) The coating swells after the hearing aid is inserted and, thus, seals off any pathways for acoustic feedback. After removal at night, the earmold dries and returns to its smaller size, ready for insertion the next day.

  • Publication number: 20050091248
    Abstract: In a network of digital computers (20), a method for facilitating access by a first digital computer (24) to a file that is stored in a local file system tree (198) of a second digital computer (22). The method includes establishing, by recursively combining hierarchical file system trees (198) that are exported from one or more NDCs (50), a hierarchical domain tree (200) that encompasses digital computers (24, 26B, 26A and 22) in the network of digital computers (20). A domain manager (212) receives policy attributes, a new type of extended attributes, and enforces policies specified therein. In a particularly preferred embodiment the policy attributes identify at least one module that must be loaded by the first digital computer (24) to extend capabilities of the first digital computer (24) used in processing a file requested from the local file system tree (198) of the second digital computer (22).
