view source
US Patent:

7450736, Nov 11, 2008
Filed:

Oct 26, 2006
Appl. No.:

11/553382
Inventors:

Ming-Hsuan Yang - Sunnyvale CA, US
Rui Li - Boston MA, US
Assignee:

Honda Motor Co., Ltd. - Tokyo
International Classification:

G06K 9/00
US Classification:

382103, 382285, 345474
Abstract:

Disclosed is a method and system for efficiently and accurately tracking three-dimensional (3D) human motion from a two-dimensional (2D) video sequence, even when self-occlusion, motion blur and large limb movements occur. In an offline learning stage, 3D motion capture data is acquired and a prediction model is generated based on the learned motions. A mixture of factor analyzers acts as local dimensionality reducers. Clusters of factor analyzers formed within a globally coordinated low-dimensional space makes it possible to perform multiple hypothesis tracking based on the distribution modes. In the online tracking stage, 3D tracking is performed without requiring any special equipment, clothing, or markers. Instead, motion is tracked in the dimensionality reduced state based on a monocular video sequence.

US Patent:

7720977, May 18, 2010
Filed:

Feb 11, 2003
Appl. No.:

10/364892
Inventors:

Rui Li - Alviso CA, US
Assignee:

Foundry Networks, Inc. - Santa Clara CA
International Classification:

G06F 15/16
US Classification:

709228, 709223, 709227, 709230, 709238
Abstract:

A switch may be used to force the expiration of a cookie on a user's system by inserting an expiration field into the cookie contained in a network response packet. Additionally, a mechanism is provided to delete or damage a cookie contained in a network request packet, so that server software is not disrupted by the receipt of a cookie. Deleting a cookie results in a cleaner request, but damaging a cookie may be more efficient in certain circumstances. By providing these features, an efficient cookie switching design is provided.

Filed:

Mar 23, 2009
Appl. No.:

12/409216
Inventors:

James Harris - San Jose CA, US
Rui Li - Santa Clara CA, US

International Classification:

H04L 29/00
H04L 29/06
G06F 15/16
US Classification:

726 12, 726 1, 726 2, 726 3, 726 4, 726 5, 726 6, 709203, 709227, 709228, 709229
Abstract:

The present invention provides a system and method for authentication of network traffic managed by a traffic management virtual server. A traffic management virtual server may determine that a client has not been authenticated from a request of the client to access a server. Responsive to the request, the traffic management virtual server may transmit a response to the client with instructions to redirect to an authentication virtual server. The authentication virtual server may receive a second request from the client. The authentication virtual server may then authenticate credentials received from the client and establish an authentication session for the client. Further, the authentication virtual server may transmit a second response to redirect the client to the traffic management virtual server. The second response identifies the authentication session. The traffic management virtual server then receives a request from the client with an identifier to the authentication session.

US Patent:

20100211626, Aug 19, 2010
Filed:

Jan 12, 2004
Appl. No.:

10/756152
Inventors:

Rui Li - San Jose CA, US
Assignee:

Foundry Networks, Inc. - Alviso CA
International Classification:

G06F 15/16
US Classification:

709203, 709227
Abstract:

A hypertext transfer protocol (HTTP) connection between a client terminal and a server includes a client-side connection and a server-side connection. Different techniques are used to extend the persistence of the HTTP connection. These techniques include keeping the server-side connection persistent if the client terminal sends a RESET to the server, keeping the server-side connection persistent but closing the client-side connection if the client terminal sends a RESET or a FIN packet to the server, rewriting a “Connection: Close” header in a request to a “Connection: Keep-Alive,” inserting a “Connection: Keep-Alive” in a header of a request, modifying a “Connection: Close” header in a request, and changing the HTTP version value in a request.

International Classification:

G06F 15/173
G06F 21/00
US Classification:

726 15, 709224
Abstract:

The present invention provides a system and method of managing traffic traversing an intermediary based on a result of end point auditing. An authentication virtual server of an intermediary may determine a result of an end point analysis scan of a client. Responsive to the determination, the traffic management virtual server can obtain the result from the authentication virtual server. Further, the traffic management virtual server may apply the result in one or more traffic management policies to manage network traffic of a connection of the client traversing the intermediary. In some embodiments, the authentication virtual server may receive one or more expressions evaluated by the client. The one or more expressions identifies one or more attributes of the client. The traffic management virtual server can also determine a type of compression or encryption for the connection based on applying the one or more traffic management policies using the result.
