Patent number: 12347997Abstract: The present disclosure provides a method for aligning a master oscillator power amplifier (MOPA) system. The method includes ramping up a pumping power input into a laser amplifier chain of the MOPA system until the pumping power input reaches an operational pumping power input level; adjusting a seed laser power output of a seed laser of the MOPA system until the seed laser power output is at a first level below an operational seed laser power output level; and performing a first optical alignment process to the MOPA system while the pumping power input is at the operational pumping power input level, the seed laser power output is at the first level, and the MOPA system reaches a steady operational thermal state.Type: GrantFiled: April 26, 2024Date of Patent: July 1, 2025Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Chun-Lin Louis Chang, Henry Tong Yee Shian, Alan Tu, Han-Lung Chang, Tzung-Chi Fu, Bo-Tsun Liu, Li-Jui Chen, Po-Chung Cheng

Patent number: 10574638Abstract: A user may desire to execute a process in a target environment. However, administrators may want control over processes that haven't been preapproved to prevent the execution of processes that may affect security and compliance within the environment. Implementation of a multi-factor execution gateway may grant the user limited access to execute the process himself at an otherwise restricted, protected, or decoupled environment, while ensuring security and compliance by obtaining approval from the appropriate authorities. For example, a request to execute the process in the environment may be detected, and a fingerprint may be generated based on parameters of the request. A signature for the fingerprint in the form of private key(s) acquired from authorizer(s) based on a level of authorization required for the process may be received to generate a key, and execution of the process may then be allowed at the environment using the key.Type: GrantFiled: April 15, 2019Date of Patent: February 25, 2020Assignee: Microsoft Technology Licensing, LLCInventor: Alan Tus

Patent number: 10394916Abstract: Technologies are described to provide a personalized search environment to users without requiring enterprise environment access. Upon access of a personal service account such as one in a productivity service, a user's personal environment may be created by an aggregation service using graph based data infrastructure. Sources of information may include personal email accounts, calendars, social/professional networks, task list applications, online data storage services, health applications, gaming applications, and communication applications associated with the user. A personalized search application may then use the data from the aggregation service and/or (if available) user's enterprise account information to perform personalized searches with relevant results for the user.Type: GrantFiled: September 13, 2016Date of Patent: August 27, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Alan Tus, Konstantin Seleskerov, Panos Sakkos, Rovin Bhandari
