Publication number: 20150294521Abstract: A magnetic currency verification head may include a magnetoresistive sensor chip, and a magnetic bias unit disposed on the side of the magnetoresistive sensor chip away from the detection surface of the magnetic currency verification head, and separated from the magnetoresistive sensor chip; the magnetoresistive sensor chip comprises a gradiometric bridge circuit that includes magnetic sensor elements; the sensitive direction of the magnetic sensor elements is parallel to the detection surface of the magnetic currency verification head; and the magnetic bias unit has a recessed magnetic structure configured such that the magnetic field generated by the magnetic bias unit only has a small magnetic field component in the direction parallel to the detection surface, thereby enabling the magnetic sensor elements to operate in their linear range. As a result, the magnetic currency verification head has high sensitivity and signal-to-noise ratio.Type: ApplicationFiled: October 30, 2013Publication date: October 15, 2015Inventors: James Geza Deak, Mingfeng Liu, Jianming Bai, Min Zhu

Patent number: 9112715Abstract: A routing system utilizes a layer 2 switch interconnecting several routers to intelligently forward multicast packets throughout an interne exchange carrying multicast content. The layer 2 switch performs protocol snooping to extract a lookup key that is based on network layer protocol information. The lookup key is uniquely formulated to support either shared or explicit source distribution trees. The lookup key is used to query a forwarding memory that returns an outgoing port index. The outgoing port index points to one or more outgoing ports that are eligible to receive the multicast packet. The outgoing ports are also connected to the neighboring device(s) that are designated to receive the multicast packet. The routing system also supports real time maintenance and updating of the forwarding memory based on the periodic exchange of control messages. The routing system is configured to support PIM routers operating in PIM SM or PIM SSM modes.Type: GrantFiled: April 22, 2010Date of Patent: August 18, 2015Assignee: Foundry Networks, LLCInventors: Nitin Jain, Lee Chen, Earl Ferguson, Min Zhu

Publication number: 20140348900Abstract: The present invention provides for a process for preparing liposomes, lipid discs, and other lipid nanoparticles using a multi-port manifold, wherein the lipid solution stream, containing an organic solvent, is mixed with two or more streams of aqueous solution (e.g., buffer). In some aspects, at least some of the streams of the lipid and aqueous solutions are not directly opposite of each other. Thus, the process does not require dilution of the organic solvent as an additional step. In some embodiments, one of the solutions may also contain an active pharmaceutical ingredient (API). This invention provides a robust process of liposome manufacturing with different lipid formulations and different payloads. Particle size, morphology, and the manufacturing scale can be controlled by altering the port size and number of the manifold ports, and by selecting the flow rate or flow velocity of the lipid and aqueous solutions.Type: ApplicationFiled: March 13, 2014Publication date: November 27, 2014Applicant: Cureport, Inc.Inventor: De-Min Zhu

Publication number: 20140192592Abstract: The present invention relates to an Sb—Te—Ti phase-change thin-film material applicable to a phase-change memory and preparation thereof. The Sb—Te—Ti phase-change memory material of the present invention is formed by doping an Sb—Te phase-change material with Ti, Ti forms bonds with both Sb and Te, and the Sb—Te—Ti phase-change memory material has a chemical formula SbxTeyTi100-x-y, where 0<x<80 and 0<y<100-x. When the Sb—Te—Ti phase-change memory material is a Ti—Sb2Te3 phase-change memory material, Ti atoms replace Sb atoms, and phase separation does not occur. In a crystallization process of an Sb—Te phase-change material in the prior art, gain growth dominates, so the phase change rate is high, but the retention cannot meet industrial requirements.Type: ApplicationFiled: December 26, 2012Publication date: July 10, 2014Applicant: Shanghai Institute of Microsystem and Information Technology Chinese AcademyInventors: Liangcai Wu, Min Zhu, Zhitang Song, Feng Rao, Cheng Peng, Xilin Zhou, Kun Ren, Songlin Feng
