The present invention discloses a method and device for detecting connectivity termination in an IPv6 access network based on a DHCP service model. The method for detecting connectivity termination according to the invention comprises the steps of: creating an entry of the subscriber connectivity cache list corresponding to the subscriber terminal in the access node when the IPv6 connectivity between the subscriber terminal and the access node is established successfully; querying the entry of the neighbor cache list corresponding to the subscriber terminal based on the polling time set in the entry of the subscriber connectivity cache list; deciding whether the connectivity of the subscriber terminal is normal based on the entry information corresponding to the subscriber terminal of the subscriber connectivity cache list and neighbor cache list; and performing termination processing on the connectivity of the subscriber terminal logging off abnormally.

A method for producing an audio-visual slideshow for a video sequence having an audio soundtrack and a corresponding video track including a time sequence of image frames, comprising: segmenting the audio soundtrack into a plurality of audio segments; subdividing the audio segments into a sequence of audio frames; determining a corresponding audio classification for each audio frame; automatically selecting a subset of the audio segments responsive to the audio classification for the corresponding audio frames; for each of the selected audio segments automatically analyzing the corresponding image frames to select one or more key image frames; merging the selected audio segments to form an audio summary; forming an audio-visual slideshow by combining the selected key frames with the audio summary, wherein the selected key frames are displayed synchronously with their corresponding audio segment; and storing the audio-visual slideshow in a processor-accessible storage memory.

If either of the MAC processing units in one of the ring connection control circuits receives a MAC frame that includes control information for the redundancy control process related to one of the subrings from that subring, then output of the relevant MAC frame to the transfer processing unit is restricted and the relevant MAC frame is output to the STP processing unit.

Several approaches to selectively filtering network traffic are described. One approach involves a system for selectively filtering network traffic. The system includes a helper application, which is coupled to a networking program, and is used to identify a user-initiated request. A network filter driver is coupled to the networking program, for intercepting the user-initiated request. A filtering service is coupled to both the helper application and the network filter driver, and is used to determine if the user-initiated request is allowable. If the request is allowable, the filtering service is configured to generate a special identifier, which the helper application is configured to include in a subsequent request. The filtering service is configured to allow a subsequent request which includes the special identifier, and the network filter driver's configured to strip a special identifier from subsequent requests.

A method of classifying a set of semantic concepts on a second multimedia collection based upon adapting a set of semantic concept classifiers and updating concept affinity relations that were developed to classify the set of semantic concepts for a first multimedia collection. The method comprises providing the second multimedia collection from a different domain and a processor automatically classifying the semantic concepts from the second multimedia collection by adapting the semantic concept classifiers and updating the concept affinity relations to the second multimedia collection based upon the local smoothness over the concept affinity relations and the local smoothness over data affinity relations.

Scalable session management is achieved by generating a cookie that includes an encrypted session key and encrypted cookie data. The cookie data is encrypted using the session key. The session key is then signed and encrypted using one or more public/private key pairs. The encrypted session key can be decrypted and verified using the same private/public key pair(s). Once verified, the decrypted session key can then be used to decrypt and verify the encrypted cookie data. A first server having the private/public key pair(s) may generate the cookie using a randomly generated session key. A second server having the same private/public key pair(s) may decrypt and verify the cookie even if the session key is not initially installed on the second server. A session key cache may be used to provide session key lookup to save public/private key operations on the servers.
摘要:
An extremely energy efficient, compact, integrated hybrid five axis passive and active magnetic bearing system is developed for suspending a rotor within a non-rotating stator without conventional rolling element or fluid film bearings wherein 1) an axial permanent magnetic set of poles generates a magnetic flux path creating an axial repulsive force which keeps the rotor axially centered in the stator without using a thrust disk or radial thrust faces, 2) two radial electromagnetic bearings generate radial magnetic flux paths which create radial forces which keep the rotor radially centered in the housing, and 3) an integrated axial/radial permanent flux path which provides a bias flux for the radial bearings.

Providing services within a network of service providers sharing an authentication service and a set of business rules. A central server receives a first request from a first server to provide a first service to a user via a client without forcing the user to present credentials. In response to the received first request, the central server stores data identifying the first service on the client. The central server further receives a second request from a second server to provide a second service to the user via the client after the user presents the credentials to the second service. After receiving the second request and the presented credentials, the central server allows the user access to the second service. In response to allowing the user access to the second service, the central server further allows the user access to the first service as a result of the stored data.
