  • Publication number: 20100042511
    Abstract: There is provided a method and system for qualification testing in a social network service. Qualification testing provides access control into a social network, wherein qualification is based on answers to questions related to a topic. In one example, members admitted to the network provide guidance, notes and research assistance to another member. The social network members access the social network from an external networked computing service, such as another social network, to facilitate easy connection to potential members. The social network may be implemented as an application overlay to the external service, or may access connections in the external network.

  • Patent number: 7577599
    Abstract: Systems and methods are provided for processing electronic payment transaction information. A transaction software engine operating in a server at a merchant's site effectuates the authorization of electronic payment requests and the settlement of authorized electronic payments. Authorization requests are sent by a terminal at the merchant's site to the server as each transaction occurs. Batches of settlement requests are processed after a predetermined time, although the transactions are processed on a transaction-by-transaction basis. The transaction software engine is capable of accepting data of varying formats and re-encoding such data so that it can be processed by a host associated with a data transaction provider. Accordingly, the transaction software engine processes data received from a variety of terminals as well as data sent to and received from a variety of data transaction providers.

  • Publication number: 20070243762
    Abstract: A hermetic pressure connector which provides a pressure-tight, electrically conductive connection through a hole in a bulkhead. The connector includes a transverse support member having a high pressure side and an opposite low pressure side. A passage extends through the transverse support member between the opposite sides. A conductor pin having an axial portion extends through the passage. An insulating sleeve surrounds at least the axial portion of the conductor pin, thereby electrically insulating the transverse support member from the conductor pin. A molded connected body surrounds at least a central portion of the conductor pin at least at one of the high and low pressure sides to thereby mechanically support the conductor pin in the passage. The molded connector body is directly sealingly engaged with the conductor pin, the insulating sleeve and the transverse support member.

  • Publication number: 20060281630
    Abstract: An apparatus, program product and method propagate errors detected in an IO fabric element from an IO fabric that is used to couple a plurality of endpoint IO resources to processing elements in a computer. In particular, such errors are propagated to the endpoint IO resources affected by the IO fabric element in connection with recovering from the errors in the IO fabric element. By doing so, a device driver or other program code used to access each affected IO resources may be permitted to asynchronously recover from the propagated error in its associated IO resource, and often without requiring the recovery from the error in the IO fabric element to wait for recovery to be completed for each of the affected IO resources. In addition, an IO fabric may be dynamically configured to support both recoverable and non-recoverable endpoint IO resources.
