Patent number: 8073952Abstract: A load balancing system is described herein that proactively balances client requests among multiple destination servers using information about anticipated loads or events on each destination server to inform the load balancing decision. The system detects one or more upcoming events that will affect the performance and/or capacity for handling requests of a destination server. Upon detecting the event, the system informs the load balancer to drain connections around the time of the event. Next, the event occurs on the destination server, and the system detects when the event is complete. In response, the system informs the load balancer to restore connections to the destination server. In this way, the system is able to redirect clients to other available destination servers before the tasks occur. Thus, the load balancing system provides more efficient routing of client requests and improves responsiveness.Type: GrantFiled: April 22, 2009Date of Patent: December 6, 2011Assignee: Microsoft CorporationInventors: Won Suk Yoo, Anil K. Ruia, Himanshu Patel, Ning Lin

Patent number: 8046432Abstract: A live caching system is described herein that reduces the burden on origin servers for serving live content. In response to receiving a first request that results in a cache miss, the system forwards the first request to the next tier while “holding” other requests for the same content. If the system receives a second request while the first request is pending, the system will recognize that a similar request is outstanding and hold the second request by not forwarding the request to the origin server. After the response to the first request arrives from the next tier, the system shares the response with other held requests. Thus, the live caching system allows a content provider to prepare for very large events by adding more cache hardware and building out a cache server network rather than by increasing the capacity of the origin server.Type: GrantFiled: April 17, 2009Date of Patent: October 25, 2011Assignee: Microsoft CorporationInventors: Won Suk Yoo, Anil K.

Patent number: 7887556Abstract: A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both. In some embodiments, the cutting element is movable between retracted and deployed positions for advancing the device to a site for treatment and for removing material, respectively.Type: GrantFiled: November 4, 2002Date of Patent: February 15, 2011Assignee: Fox Hollow Technologies, Inc.Inventors: John B.

More particularly, the first module may be a pumping module that delivers a fluid, such as a medication, to a patient while the second module may be a programming module that allows a user to select pump flow commands. The second module is removably attachable to the first module.Type: ApplicationFiled: September 13, 2010Publication date: January 13, 2011Applicant: MEDTRONIC MINIMED, INC.Inventors: Emilian Istoc, Himanshu Patel

Publication number: 20100318632Abstract: A caching system segments content into multiple, individually cacheable chunks cached by a cache server that caches partial content and serves byte range requests with low latency and fewer duplicate requests to an origin server. The system receives a request from a client for a byte range of a content resource. The system determines the chunks overlapped by the specified byte range and sends a byte range request to the origin server for the overlapped chunks not already stored in a cache. The system stores the bytes of received responses as chunks in the cache and responds to the received request using the chunks stored in the cache. The system serves subsequent requests that overlap with previously requested ranges of bytes from the already retrieved chunks in the cache and makes requests to the origin server only for those chunks that a client has not previously requested.Type: ApplicationFiled: June 16, 2009Publication date: December 16, 2010Applicant: Microsoft CorporationInventors: Won Suk Yoo, Anil K.

Patent number: 7771444Abstract: A debulking catheter comprising a debulking assembly for debulking a body lumen. The catheters of the present invention can include a flexible proximal portion coupled to a rigid distal portion. A tissue debulking assembly can be disposed within the rigid portion to debulk the body lumen. In exemplary embodiments, the rigid portion is rotatably coupled to the flexible portion such that rotation or deflection of the rigid portion, relative to the flexible portion, can expose the tissue debulking assembly through a window in the catheter to debulk the body lumen.Type: GrantFiled: December 19, 2001Date of Patent: August 10, 2010Assignee: Fox Hollow Technologies, Inc.Inventors: Himanshu Patel, John B.

Publication number: 20100198240Abstract: A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.Type: ApplicationFiled: April 9, 2010Publication date: August 5, 2010Applicant: FOX HOLLOW TECHNOLOGIES, INC.Inventors: John B.
