Patent number: 11788833Abstract: Method and system for defining basis functions for fitting distortions of profiles of objects in a batch, that has undergone a fabrication process, in a manner adaptable to the fabrication process to reduce the errors between profiles approximated with the use of such basis functions and actual object profiles. Process-specific individual basis functions are defined based on spatially-dense measurement of objects from training sub-set of the batch and applying learning algorithm to results of such measurement. Advantages of process-adaptable basis functions over generic basis functions for fitting distortion shapes of objects include higher accuracy of fitting either at larger or a fewer locations across the object.Type: GrantFiled: May 29, 2020Date of Patent: October 17, 2023Assignee: Nikon CorporationInventors: Travis D. Bow, Henry Pang, Fardad A. Hashemi

Patent number: 11341008Abstract: While the management module of an information handling system is set as a standby module, an enclosure controller provides first requests for attribute data of the information handling system, and receives and stores first response data for attribute data associated with a first subset of the first requests in a local memory of the enclosure controller. The enclosure controller receives request failure responses associated with a second subset of the first requests directed to a subset of the attributes data for the information handling system stored in a shared memory. While the management module is set as an active module, the management module is granted access to the shared memory. The enclosure controller provides retry requests for attributes associated with the request failure responses, and receives and stores second response data associated with the retry requests in the local memory.Type: GrantFiled: March 19, 2021Date of Patent: May 24, 2022Assignee: Dell Products L.P.Inventors: Michael E. Brown, Joshua M. Pennell, Henry Pang

Patent number: 10615876Abstract: A controller area network (CAN) comprising a plurality of CAN nodes that communicate via a CAN bus that comprises a fiber optical network. The fiber optical network uses a single fiber and a single wavelength for transmit and receive, and comprises a passive reflective optical star. The reflective optical star comprises an optical mixing rod having a mirror at one end. The other end of the reflective optical star is optically coupled to the transmitters and receivers of a plurality of optical-electrical media converters by way of respective high-isolation optical Y-couplers. Each CAN node produces electrical signals (in accordance with the CAN message-based protocol) which are converted into optical pulses that are broadcast to the fiber optical network. Those optical pulses are then reflected back to all CAN nodes by the reflective optical star.Type: GrantFiled: March 16, 2019Date of Patent: April 7, 2020Assignee: The Boeing CompanyInventors: Tuong K. Truong, Eric Y. Chan, Dennis G. Koshinz, Kim Quan Anh Nguyen, Barkhung Henry Pang, Sean M. Ramey, Timothy E. Jackson

Patent number: 9829967Abstract: A power subsystem is configured to manage the maximum power usage of a computer subsystem. A power detector determines when power usage approaches the maximum capability of the power supply. The power detector generates a signal that corresponds to power usage. A controller then applies the signal to the system voltage regulator as a secondary regulation function such that the output voltage is reduced in a manner that supports maximum operating voltage while limiting power usage to within the capability of the power supply. The controller may configure the signal to implement the secondary regulation function as a modification of the feedback voltage, the reference voltage, or the current feedback of the regulator. As a result the subsystem causes the computer subsystem to operate at an optimum point on the voltage-current curve of the power supply.Type: GrantFiled: October 8, 2015Date of Patent: November 28, 2017Assignee: NVIDIA CorporationInventors: Sam Duell, Jonah Alben, Andrew R.
