Publication number: 20230408120Abstract: A method is provided. In some examples, the method includes receiving a first user input at processing circuitry. The method also includes determining, by the processing circuitry based on a signal from a radar sensor, movement of a user in a room after receiving the first user input. In addition, the method includes determining, by the processing circuitry, a first estimated location of a first wall in the room based on a first portion of the movement of the user. The method further includes determining, by the processing circuitry, a second estimated location of a second wall in the room based on a second portion of the movement of the user.Type: ApplicationFiled: July 29, 2022Publication date: December 21, 2023Inventors: Dan Wang, Slobodan Jovanovic, Sandeep Rao

Publication number: 20120142947Abstract: Compositions and methods are directed to covalent adducts between reducing agents and optionally substituted 3-hydroxyflavans, wherein the reducing agent is covalently bound to the B-ring of the 3-hydroxyflavan. Such adducts exhibit markedly increased stability towards oxidation as compared to the unmodified 3-hydroxyflavan. Particularly preferred 3-hydroxyflavans include green tea catechins, and especially EGCG, while especially preferred reducing agents include NAC and glutathione.Type: ApplicationFiled: February 13, 2012Publication date: June 7, 2012Inventors: Yukihiko Hara, Hiroshi Hojo, Slobodan Jovanovic

Patent number: 7627252Abstract: A method of recovering a clock signal from an optical signal received through an optical communications system. A digital sample stream is processed to generate a dispersion compensated signal. The dispersion compensated signal is then tapped to obtain upper side band and lower side band signals of each received polarization of the optical signal. The upper side band and lower side band signals are then processed to compensate polarization dependent impairments, and the clock recovered from the resulting optimized.Type: GrantFiled: December 23, 2005Date of Patent: December 1, 2009Assignee: Nortel Networks LimitedInventors: Han Sun, Slobodan Jovanovic, Kuang Tsan Wu, Chandra Bontu, Kim B Roberts, Jianzhong Xu

Patent number: 6888794Abstract: A method and apparatus for exchanging data rate information across a packet-based network, is presented herein. In accordance with an embodiment of the invention, a first and second communication device, configured to operate as data sources, sinks, or both, communicate with a first and second gateway mechanism, respectively. The first gateway mechanism receives data rate information from the first communication device to determine a first data signaling rate between the first communication device and the first gateway mechanism. Similarly, the second gateway mechanism receives data rate information from the second communication device to determine a second data signaling rate between the second communication device and the second gateway mechanism. The first gateway forwards data rate information containing the first data signaling rate to the second gateway mechanism and the second gateway mechanism forwards data rate information containing the second data signaling rate to the first gateway mechanism.Type: GrantFiled: November 13, 2000Date of Patent: May 3, 2005Assignee: Nortel Networks LimitedInventors: Slobodan Jovanovic, Mehul Mehta, Zongyao Zhou

Patent number: 6819750Abstract: A method and apparatus for establishing communication between a sending facsimile machine and a receiving facsimile machine first receives an answer tone message for a specified time. It then is determined if a given joint menu message has been received from the receiving facsimile machine at any time during the specified time. If it is determined that the given joint menu message has not been received from the receiving facsimile machine at any time during the specified time, then the above noted alias joint menu message is forwarded to the sending facsimile machine. The alias joint menu message is different from the given joint menu signal and thus, not a true joint menu message that can be used by the sending facsimile machine.Type: GrantFiled: October 26, 2000Date of Patent: November 16, 2004Assignee: Nortel Networks LimitedInventors: Mehul Mehta, Slobodan Jovanovic, Aleksandar Purkovic
