Publication number: 20210013357Abstract: In an example, an avalanche photodiode comprises a substrate and a structure comprising a first layer and a second layer, the first and second layers over and parallel to the substrate, wherein the first layer is between the substrate and the second layer. The first layer is an Aluminium Arsenide Antimonide multiplication layer, and wherein the cross-sectional area parallel to the substrate of the first layer is smaller than that of the second layer, thereby forming a recess in a sidewall of the structure.Type: ApplicationFiled: July 8, 2019Publication date: January 14, 2021Applicants: University College Cardiff Consultants Limited, The Regents of The University of California, University of SheffieldInventors: Baolai Liang, Shiyu Xie, Diana Lynne Huffaker, John Paul Raj DAVID, Chee Hing Tan

Patent number: 9806820Abstract: Embodiments of the present invention disclose an optical transmitter and an optical transmission method. An embodiment of the present invention includes a directly modulated laser array and a micro-ring group array, where the directly modulated laser array may output multiple channels of optical signals, each directly modulated laser is correspondingly provided with one circular waveguide group and one first waveguide, each circular waveguide group may couple a part of optical signals output by a directly modulated laser corresponding to the circular waveguide group to a same second waveguide, and the second waveguide aggregates optical signals from circular waveguide groups and outputs an aggregated optical signals. The micro-ring group array implements not only filtering but also multiplexing, which effectively reduces a quantity of elements, reduces a size of an optical transmitter, and reduces costs.Type: GrantFiled: June 30, 2016Date of Patent: October 31, 2017Assignee: Huawei Technologies Co., Ltd.Inventors: Haili Wang, Xi Chen, Shiyu Xie, Shengmeng Fu

Patent number: 8584233Abstract: Providing malware-free web content to a user is disclosed. The web content is any type of web content that may potentially be infected by any type of malware. Upon receiving a request for a piece of web content from the user, the requested piece of web content is obtained from the appropriate source, and a dynamic template for the piece of web content is retrieved. The dynamic template indicates whether the requested piece of web content includes any malware and what actions are to be performed if any malware is included in the piece of web content. The requested piece of web content is cleaned up by performing the actions indicated in the dynamic template. Thereafter, the piece of web content is provided to the user. The dynamic template is updated from time to time based on the currently available information regarding the piece of web content.Type: GrantFiled: May 5, 2008Date of Patent: November 12, 2013Assignee: Trend Micro Inc.Inventors: Liulin Yang, Kun Lu, Shiyu Xie

Patent number: 8379816Abstract: A method for managing a phishing call is provided. The method includes receiving an incoming telecommunication request. The method also includes comparing a unique identification associated with the incoming telecommunication request against a set of contact lists. The method further includes, if the unique identification is not found on the set of contact lists, activating a delay timer to prevent a set of user notification components from being triggered for a delay period. The method yet also includes performing a connection analysis to determine status of the incoming telecommunication request. The method moreover includes, if the incoming telecommunication request is terminated during the delay period, updating a phishing call log with data about the incoming telecommunication request, wherein the updating of the phishing call log occurs without the set of user notification components being triggered, responsive to the incoming telecommunication request, during or subsequent to the updating.Type: GrantFiled: May 15, 2008Date of Patent: February 19, 2013Assignee: Trend Micro IncorporatedInventors: Kun Lu, Yi Cai, Shiyu Xie

Patent number: 8213923Abstract: Methods and apparatus for updating security software products on mobile telephones are described. When an update is available for a security software product installed on a mobile telephone, a server encodes and optionally compresses the update data from binary format into audio format. The server establishes a voice connection with the mobile telephone. The update data in audio format is transmitted to the mobile telephone via the voice connection. Upon receiving the complete update data in audio format, the mobile telephone decodes and optionally decompresses the update data from audio format back into binary format. The security software product installed on the mobile telephone is updated using the update data in binary format.Type: GrantFiled: November 2, 2007Date of Patent: July 3, 2012Assignee: Trend Micro IncorporatedInventors: Kun Lu, Shiyu Xie, Liulin Yang
