Patent number: 11973772Abstract: Conventional email filtering services are not suitable for recognizing sophisticated malicious emails, and therefore may allow sophisticated malicious emails to reach inboxes by mistake. Introduced here are threat detection platforms designed to take an integrative approach to detecting security threats. For example, after receiving input indicative of an approval from an individual to access past email received by employees of an enterprise, a threat detection platform can download past emails to build a machine learning (ML) model that understands the norms of communication with internal contacts (e.g., other employees) and/or external contacts (e.g., vendors). By applying the ML model to incoming email, the threat detection platform can identify security threats in real time in a targeted manner.Type: GrantFiled: February 22, 2022Date of Patent: April 30, 2024Assignee: Abnormal Security CorporationInventors: Sanjay Jeyakumar, Jeshua Alexis Bratman, Dmitry Chechik, Abhijit Bagri, Evan Reiser, Sanny Xiao Lang Liao, Yu Zhou Lee, Carlos Daniel Gasperi, Kevin Lau, Kai Jiang, Su Li Debbie Tan, Jeremy Kao, Cheng-Lin Yeh

Patent number: 11955553Abstract: Embodiments disclosed herein relate to using an implantation process and a melting anneal process performed on a nanosecond scale to achieve a high surface concentration (surface pile up) dopant profile and a retrograde dopant profile simultaneously. In an embodiment, a method includes forming a source/drain structure in an active area on a substrate, the source/drain structure including a first region comprising germanium, implanting a first dopant into the first region of the source/drain structure to form an amorphous region in at least the first region of the source/drain structure, implanting a second dopant into the amorphous region containing the first dopant, and heating the source/drain structure to liquidize and convert at least the amorphous region into a crystalline region, the crystalline region containing the first dopant and the second dopant.Type: GrantFiled: February 24, 2023Date of Patent: April 9, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Su-Hao Liu, Kuo-Ju Chen, Wen-Yen Chen, Ying-Lang Wang, Liang-Yin Chen, Li-Ting Wang, Huicheng Chang

Patent number: 11733994Abstract: A data processing device for providing data storage services includes memory, persistent storage, and a device manager. The persistent storage stores a code repository. The state manager obtains a code update request for a new state for the device manager; injects state manager code to begin execution of the state manager in response to obtaining the code update request; updates the device manager data using the code repository and a memory region state map to obtain an updated device manager; and extracts the state manager code to resume execution of the updated device manager.Type: GrantFiled: May 3, 2019Date of Patent: August 22, 2023Assignee: EMC IP Holding Company LLCInventors: Jonathan I. Krasner, Li Lang, Avraham Goldin

Patent number: 11086536Abstract: Techniques for performing configuration may include: determining an initial distribution of logical devices among disk adapters, wherein the initial distribution assigns each logical device a designated disk adapter as a primary active disk adapter servicing I/Os directed to the logical device, wherein the logical devices have storage provisioned from a RAID group including physical storage devices, wherein the disk adapters concurrently issue I/Os to each of the physical storage devices; detecting a configuration change; and responsive to detecting a configuration change, performing first processing. The first processing may include determining, in accordance with the configuration change, a redistribution of the logical devices among the disk adapters; and draining pending I/Os. The configuration change may include adding or removing a logical device provisioned from the RAID group.Type: GrantFiled: July 30, 2018Date of Patent: August 10, 2021Assignee: EMC IP Holding Company LLCInventors: Peng Yin, Kunxiu Gao, Jiahui Wang, Seema G. Pai, Ningdong Li, Daohong Wang, Stephen Richard Ives, Li Lang

Patent number: 9524324Abstract: Described are techniques for processing a request to update a globally shared data item. The request is received at a first processor designated as the master processor. Other processors are designated as non-master processors. The first processor sends a synchronization request message to the other processors. The first processor waits a predetermined amount of time for the other processors to signal to the first processor regarding commitment in executing the request. Responsive to the first processor receiving the signal from the other processors first processing is performed that includes the first processor notifying the other processors regarding completion of a first synchronization point, updating the globally shared data item by said first processor, and waiting, by the other processors, for notification from the first processor regarding completion of a second synchronization point thereby indicating that updating of the globally shared data item is completed.Type: GrantFiled: December 26, 2012Date of Patent: December 20, 2016Assignee: EMC CorporationInventors: Ashutosh Lakhani, Roii Raz, Ghil Iancovici, Li Lang, Gabriel Hershkovitz
