| 20110029596 | Anycast Transport Protocol for Content Distribution Networks - A cache server for providing content includes a processor configured to receive a first datagram from a client system sent to an anycast address, send a response datagram to the client system in response to the first datagram, receive a request datagram from the client system sent to the anycast address, and send a batch of content datagrams to the client system. The first datagram includes a universal resource locator corresponding to the content. The response datagram includes a content identifier for the content. The request datagram includes the content identifier, an offset, and a bandwidth indicator. The batch of content datagrams includes a portion of the content starting at the offset. | 02-03-2011 |
| 20110119761 | Mitigating Low-Rate Denial-of-Service Attacks in Packet-Switched Networks - A method includes determining, at a network routing device, an average packet drop rate for a plurality of aggregations of packet flows. The method also determines a threshold packet drop rate based on the average packet drop rate, a current packet drop rate for a select aggregation of the plurality of aggregations, and whether at least one packet flow of the select aggregation is potentially subject to a denial-of-service attack based on a comparison of the current packet drop rate to the threshold packet drop rate. | 05-19-2011 |
| 20110153941 | Multi-Autonomous System Anycast Content Delivery Network - A content delivery network includes first and second sets of cache servers, a domain name server, and an anycast island controller. The first set of cache servers is hosted by a first autonomous system and the second set of cache servers is hosted by a second autonomous system. The cache servers are configured to respond to an anycast address for the content delivery network, to receive a request for content from a client system, and provide the content to the client system. The first and second autonomous systems are configured to balance the load across the first and second sets of cache servers, respectively. The domain name server is configured to receive a request from a requestor for a cache server address, and provide the anycast address to the requestor in response to the request. The anycast island controller is configured to receive load information from each of the cache servers, determine an amount of requests to transfer from the first autonomous system to the second autonomous system; send an instruction to the first autonomous system to transfer the amount of requests to the second autonomous system. | 06-23-2011 |
| 20110231475 | Internet Protocol Version 6 Content Routing - A content delivery system includes a cache server, a domain name server, and a redirector. The domain name server is configured to receive a request for a cache server address, and provide an IPv6 anycast address. The redirector is configured to receive a content request addressed to the IPv6 anycast address from a client system, receive load information from the cache server, and determine if the cache server is available. The redirector is further configured to forward the content request to the cache server when the cache server is available. The cache server is configured to receive the content request forwarded from the redirectors, send a response to the content request to a client system, the response including an IPv6 unicast address of the cache server as a source address, an IPv6 unicast address of the client system as a destination address, and the IPv6 anycast address as a home address, and provide the content to the requestor. | 09-22-2011 |

| 20100102936 | REMOTELY CONTROLLABLE POWER SWITCH OF AN APPLIANCE AND METHODS OF EMPLOYING THE SAME - A remotely controllable power switch of an appliance and a method of employing a remotely controllable power switch of an appliance to control the overall load that an electric power distribution network bears. The method may include a method of employing a remotely controllable power switch of an appliance to compute the rate that a particular customer pays for electric power. In one embodiment, the remotely controllable power switch of an appliance includes: (1) a switching device coupled between an input and an output of the remotely controllable power switch of an appliance and (2) communication circuitry coupled to the switching device, addressable only by class and configured to receive a turn-off signal and turn off the switching device in response thereto. | 04-29-2010 |
| 20100103173 | REAL TIME OBJECT TAGGING FOR INTERACTIVE IMAGE DISPLAY APPLICATIONS - Apparatus and methods that track the location of an object within a video image at the time of capture of the video image are described. The location of the object within each frame can be recorded as meta-data for the video image so that when the video image is played back, a viewer can select the object using suitable interaction means and be linked through to a source of additional information about the object, such as a product website or the like. A device emitting radio frequency (RF) signals is attached to an object that is to be identified and tracked within a video image. Using an RF receiver with multiple antennas and applying trilateration techniques, the object's location within the video image is determined in real time and recorded as the video image is recorded. Where multiple objects are to be tracked, each object is provided with a radio device having a unique ID and the location of each device within the video image is recorded. The described solution automates an otherwise manual, error-prone and time-consuming process. | 04-29-2010 |
| 20100211982 | A/V PREMISES DECODER, A CONTENT MANAGER, A VIDEO INSERTION SYSTEM INCLUDING BOTH THE DECODER AND MANAGER, AND A METHOD OF INSERTING LOCAL CONTENT INTO A VIDEO STREAM AT A CUSTOMERS PREMISES - A multimedia (audio and video) insertion system, an A/V premises decoder, a content manager and a method of inserting local content into a multimedia stream at a customer's premises. In one embodiment, the A/V premises decoder includes: (1) a signal converter configured to convert a received digital multimedia stream to an analog multimedia stream, and (2) a content inserter configured to insert secondary content in the analog multimedia stream based on control information associated with the secondary content. | 08-19-2010 |
| 20110084664 | METHOD AND APPARATUS OF STORED ENERGY MANAGEMENT IN BATTERY POWERED VEHICLES - A secondary battery and charging system are provided within an electric car or other electric drive vehicle. The secondary battery may, e.g., be owned by the electric utility. The battery is removable and can be charged and discharged independently of the primary car battery system. The utility can use the secondary battery to implement vehicle-to-grid functionality. | 04-14-2011 |
| 20110084665 | Method and apparatus of stored energy management in battery powered vehicles - A secondary battery and charging system are provided within an electric car or other electric drive vehicle. The secondary battery may, e.g., be owned by the electric utility. The battery is removeable and can be charged and discharged independently of the primary car battery system. The utility can use the secondary battery to implement vehicle-to-grid functionality. | 04-14-2011 |
