  • Patent number: 7688849
    Abstract: A method and system for maintaining quality of service parameters for transmissions as a native Ethernet service between a first network having a first communication protocol and a second network having a second communication protocol that is different from the first communication protocol. The interworking device includes a first network interface operable to communicate with the first communication network using the first communication protocol, a second network interface operable to communicate with the second communication network using second communication protocol and a processing unit in communication with the first network interface and the second network interface. The processing unit receives a frame from the first network in the first communication protocol, maps parameters corresponding to quality of service parameters in the first communication protocol to quality of service parameters in the second communication protocol and assembles a data packet in the second communication protocol.

  • Patent number: 7467146
    Abstract: System, method and program product determine whether a first web page returned to a web browser is a redirected web page. A dummy URL is created by appending one or more characters to a URL of the first web page. The one or more characters are chosen such that the dummy URL is likely to elicit a redirected web page. The request for the dummy URL is sent. A second web page is received in response to the request. The content of the second web page is compared to content of the first web page to determine if the first web page is a redirected web page. If the content of the second web page matches the content of the first web page, a record is made indicating that the first web page is a redirected web page.

The lifting foil has an upper surface and a lower surface. The upper surface of the lifting foil is substantially planar and the lower surface of the lifting foil is not coplanar with the upper lifting surface. The lifting foil has a fore portion and an aft portion that are traversed by a longitudinal axis and wherein the longitudinal axis is substantially parallel to the longitudinal axis of the hull and the thickness of the foil is greater at the aft portion than at the fore portion.
