Publication number: 20100077018Abstract: Techniques are disclosed for generating and managing presentities in accordance with a virtual presence server. By way of example, a method for requesting information from at least one server comprises the following steps. A client request, which expresses a request that can not be satisfied by a single existing presentity, is obtained at an intermediate server, wherein the intermediate server operates as a virtual presence server. The virtual presence server (i.e., intermediate server) creates a set of software objects for a virtual presentity, the set of objects embodying logic to combine presence information from one or more of existing presentities and external information sources, in accordance with at least one existing presence server. The virtual presence server creates an association between the request of the client and the created virtual presentity that allows the presence information to be propagated back to the client.Type: ApplicationFiled: September 19, 2008Publication date: March 25, 2010Inventors: Arup Acharya, Nilanjan Banerjee, Dipanjan Chakraborty, Koustuv Dasgupta, Archan Misra, Xiping Wang, Charles P.

Publication number: 20090177779Abstract: A technique for use in a client, wherein the client supports a state-based signaling protocol (e.g., Session Initiation Protocol or SIP), includes initiating a given session state between the client and a server that also supports the state-based signaling protocol, and refreshing the given session state in a randomized manner. Further, a technique for use in a server, wherein the server supports a state-based signaling protocol (again, e.g., SIP), includes randomly assigning an expiration time duration for a given session state between the server and a client that also supports the state-based signaling protocol, and reporting the randomly assigned expiration time for the given session state to the client. By randomizing various behaviors of the client, the server, or both, bursty traffic in the communication network is reduced or eliminated.Type: ApplicationFiled: January 9, 2008Publication date: July 9, 2009Inventors: Gary John DeVal, Curtis Eldon Hrischuk, Erich Miles Nahum, John Michael Tracey, Xiping Wang, Charles P.

Patent number: 7522581Abstract: A method for operating a server having a maximum capacity for servicing requests comprises the following steps: receiving a plurality of requests; classifying each request according to a value; determining a priority for handling the request according to the value, such that requests with higher values are assigned higher priorities; placing each request in one of multiple queues according to its priority value; and dropping the requests with the lowest priority when the plurality of requests are received at a rate that exceeds the maximum capacity. The server operates according to a session initiation protocol. Classifying each request comprises running a classification algorithm.Type: GrantFiled: August 1, 2006Date of Patent: April 21, 2009Assignee: International Business Machines CorporationInventors: Arup Acharya, Erich M.

Publication number: 20090063638Abstract: Techniques are disclosed for processing messages in a messaging system, particularly during an overload condition. For example, a method of processing messages of an instant messaging system includes the following steps. A message from a first instant messaging user is received during an overload condition. A message type associated with the received message is determined. The method then decides whether to send the message to a second instant messaging user based on the determined message type of the received message. In another method, processing messages in an instant messaging system includes the following steps. Presence information associated with a first instant messaging system user is received. The presence information is sent to a second instant messaging system user when the second messaging system user requests the presence information associated with the first instant messaging system user.Type: ApplicationFiled: August 29, 2007Publication date: March 5, 2009Inventors: Lei Guo, Erich Miles Nahum, John Michael Tracey, Dinesh Chandra Verma, Xiping Wang, Charles P.

Patent number: 7355584Abstract: Projector and camera arrangements are provided for use in electronic whiteboard systems. Specifically, the present invention provides projector and camera arrangements wherein the projector and camera share the same imaging optics. By sharing the same projection and camera optics, the distortions that affect the projection system are the same as those of the camera system. Thus, the calibration step required in conventional whiteboard systems where the projector and camera are separate, i.e., each having their own distinct optics and settings, is no longer needed. Further, the arrangements provided in accordance with the invention are self-aligning, even when lens distortions are large and even in the presence of strong perspective effects. The shared optics projector and camera arrangements of the invention also provide for dynamic zooming. In addition, various active and passive optical marker or lightpen designs are provided for use in electronic whiteboard systems.Type: GrantFiled: March 15, 2005Date of Patent: April 8, 2008Assignee: International Business Machines CorporationInventors: Ferdinand Hendriks, Zon-Yin Shae, Belle L.

Patent number: 7282042Abstract: A safety syringe has a simple structure, is convenient to use, and has a low cost. The safety syringe includes a sliding casing, a needle, a syringe barrel, a piston, a latching casing, a spring and a plunger inside the syringe barrel. The safety syringe can be easily used to carry out an injection and has a safety mechanism that can be actuated using a single hand. The sliding casing can be automatically positioned and locked in two directions. This design guarantees that, during processing of the syringe after it is used, the needle's point is always protected by the sliding casing. The safey syringe is also auto-locking; after it has been used, the plunger is locked in the syringe barrel and cannot be pulled out any longer. Any attempt to use the syringe again will cause the plunger to be broken and the syringe to be damaged, thus ensuring a one-time use.Type: GrantFiled: April 14, 2004Date of Patent: October 16, 2007Inventor: Xiping Wang
