Patent number: 11962456Abstract: Example aspects include techniques for employing cross-service diagnostics for cloud service providers. These techniques may include dynamically generating a workflow of one or more diagnostic modules based on relationship information between an origin service experiencing an incident and one or more related services that the origin service depends on, and executing the workflow of one or more diagnostic modules to determine a root cause of the incident, each of the one or more diagnostic modules implemented by an individual service of the one or more related services in accordance with a schema. In addition, the techniques may include determining a diagnostic action based on the root cause, and transmitting, based on the diagnostic action, an engagement notification to a responsible entity.Type: GrantFiled: July 21, 2021Date of Patent: April 16, 2024Assignee: Microsoft Technology Licensing, LLCInventors: Zhangwei Xu, Xiaofeng Gao, Cary L. Mitchell, Steve J. Lunsman, Tony V. Perez, Arvind Narasimhan

Patent number: 11950029Abstract: The present disclosure relates to a vibrating mirror adjustment apparatus, system and method, and a projector. The vibrating mirror adjustment apparatus includes: an image feature acquiring module, an image identifying module, a resolution extracting module, and a vibrating mirror control module. The vibrating mirror adjustment apparatus identifies the category of the projected image and the resolution information corresponding to the projected image based on the acquired information feature of the projected image, then identifies whether vibration of the vibrating mirror is used to improve a resolution of an image, and further automatically controls the on or off state of the vibrating mirror, such that an optimal projection display effect is achieved, and visual enjoyment of a user is greatly improved.Type: GrantFiled: July 16, 2021Date of Patent: April 2, 2024Assignee: IVIEW DISPLAYS (SHENZHEN) COMPANY LTD.Inventors: Yong Li, Zhiqiang Gao, Steve Yeung, Tak Yeung

Publication number: 20240007058Abstract: Circuits and methods for an amplifier (particularly LNAs) that achieve wideband output impedance matching and high gain while simultaneously rejecting out-of-band (OOB) harmonic frequencies. Some embodiments allow multiple modes of operation to allow selection of gain versus linearity characteristics. One aspect of the present invention is improvement of the linearity and sensitivity of a whole RF “front end” (RFFE) receiver chain by suppressing OOB gain within an LNA component at higher order harmonic frequencies. Another aspect of the present invention are new wideband and ultra-wideband LNA load circuits that, while achieving high frequency OOB rejection, maintain in-band high gain and wideband output impedance matching at the same time. Yet another aspect of the present invention are new ultra-wideband LNA output impedance matching circuits.Type: ApplicationFiled: June 30, 2022Publication date: January 4, 2024Inventors: Emre Ayranci, Mengsheng Rui, Miles Sanner, Steve Gao

Patent number: 10734957Abstract: A circuit comprises a Sallen-Key filter, which includes a source follower that implements a unity-gain amplifier; and a programmable-gain amplifier coupled to the Sallen-Key filter. The circuit enables programmable gain via adjustment to a current mirror copying ratio in the programmable-gain amplifier, which decouples the bandwidth of the circuit from its gain settings. The programmable-gain amplifier can comprise a differential voltage-to-current converter, a current mirror pair, and programmable output gain stages. The Sallen-Key filter and at least one branch in the programmable-gain amplifier can comprise transistors arranged in identical circuit configurations.Type: GrantFiled: March 13, 2019Date of Patent: August 4, 2020Assignee: Tensorcom, Inc.Inventors: Zaw Soe, Kevin Jing, Steve Gao
