Patent number: 8923123Abstract: A system and method are provided for implementing performance improvements in a multicast protocol for networks that support incipient congestion indications via packet marking in instances of packet loss in the network during time-correlated blockages by providing indications in the physical (PHY) layer. A receiver rate calculation is adjusted so that a loss due to blockage is ignored completely and only packets marked using an Explicit Congestion Notification (ECN) packet marking protocol are treated as losses. Receiver rates are modified based on ECN principles to ignore losses. A NORM receiver rate equation may remain substantially unchanged while a sender is enabled to keep sending at a higher data rate, even in instances of blockage in support of higher system throughputs without defining a completely new receiver rate equation. Time-correlated blockages are not treated as losses.Type: GrantFiled: November 2, 2012Date of Patent: December 30, 2014Assignee: Lockheed Martin CorporationInventors: Amit Kulkarni, Xiaogang Wang, Orhan Cagri Imer, Anshul Kantwala

Patent number: 8457406Abstract: A device and method for processing an image to create appearance and shape labeled images of a person or object captured within the image. The appearance and shape labeled images are unique properties of the person or object and can be used to re-identify the person or object in subsequent images. The appearance labeled image is an aggregate of pre-stored appearance labels that are assigned to image segments of the image based on calculated appearance attributes of each image segment. The shape labeled image is an aggregate of pre-stored shape labels that are assigned to image segments of the image based on calculated shape attributes of each image segment. An identifying descriptor of the person or object can be computed based on both the appearance labeled image and the shape labeled image. The descriptor can be compared with other descriptors of later captured images to re-identify a person or object.Type: GrantFiled: March 26, 2012Date of Patent: June 4, 2013Assignee: Lockheed Martin CorporationInventors: Gianfranco Doretto, Xiaogang Wang, Thomas B.

Publication number: 20120212862Abstract: A method and a device for limiting secondary arc current of an extra-high voltage/ultra-high voltage double circuit line on the same tower. The method comprises the following steps: determining the type of a single-phase-to-ground fault when the extra-high voltage/ultra-high voltage double circuit line on the same tower has a single-phase-to-ground fault (S501); selecting a reactance value of a neutral grounding reactor according to the type of the single-phase-to-ground fault (S502); and switching the extra-high voltage/ultra-high voltage double circuit line on the same tower to the selected reactance value of the neutral grounding reactor (S503). Thus the reactance value of the neutral grounding reactor is not constant, but is changed along with the operating conditions of the power transmission line, that is, the reactance value of the neutral grounding reactor is controllable.Type: ApplicationFiled: August 19, 2010Publication date: August 23, 2012Applicants: STATE GRID CORPORATION OF CHINA, CHINA ELECTRIC POWER RESEARCH INSTITUTEInventors: Liangeng Ban, Jiming Lin, Zutao Xiang, Bin Han, Xiaogang Wang, Xiaotong Wang, Ruihua Song, Hongtao Liu, Bin Zheng
