Patent number: 10936003Abstract: Systems and methods are disclosed for phase locking multiple clocks of different frequencies. In certain embodiments, an apparatus may be configured to downsample a first clock having a first frequency and a second clock having a second frequency into downsampled clocks having the same frequency. The apparatus may adjust a frequency of the second clock so that the downsampled clocks are phase aligned. The apparatus may reset counters of the divider circuits that perform the downsampling so align them to a counter for the first clock. A counter for the second clock may also be reset to align with the counter for the first clock. The synchronized clocks may be applied in data storage operations, such as self-servo writing operations, where the first clock may be a read clock and the second clock may be a write clock.Type: GrantFiled: November 3, 2017Date of Patent: March 2, 2021Assignee: Seagate Technology LLCInventors: Zheng Wu, Jason Bellorado, Marcus Marrow, Trung Thuc Nguyen, Wing Fai Hui, Kin Ming Chan

Patent number: 10917173Abstract: Communication bottlenecks, particularly in the downlink direction, are a common problem for many CubeSat developers. As described herein, a CubeSat module for a CubeSat comprises an optical transmitter to transmit data to a remote terminal, a receiver to acquire an optical beacon from a remote terminal, and a fine-pointing module operably and directly coupleable to a coarse-pointing module of the CubeSat. The fine-pointing module is configured to point the optical transmitter toward the remote terminal with an accuracy range that overlaps with an accuracy range of the coarse-pointing module of the CubeSat so as to establish a communications link between the CubeSat and the remote terminal over a low-Earth-orbit (LEO) distance.Type: GrantFiled: September 24, 2019Date of Patent: February 9, 2021Assignee: Massachusetts Institute of TechnologyInventors: Ryan Wallace Kingsbury, Kathleen Michelle Riesing, Kerri Cahoy, Tam Nguyen Thuc Nguyen, David O.

Publication number: 20200376722Abstract: The air eliminator valve helps to eliminate air in the plastic resin used for composite products manufacturing. During operation, it continuously eliminates the air bubbles in the plastic resin running through the valve, and then transfers the filtered plastic resin into the mold. The design of the air eliminator valve consists of: inlet, inlet lock, air vent, upper cover, main body, ultrasonic generator, outlet lock and outlet. In which, the ultrasonic generator plays a role in generating ultrasonic waves to the plastic resin in the valve body that allows speeding up the air releasing process out the plastic resin. The air content in the valve could go out through the air vent on the upper cover, its status “open/close” is controlled by airlock with automatic response mechanism.Type: ApplicationFiled: May 27, 2020Publication date: December 3, 2020Applicant: VIETTEL GROUPInventors: ANH VU NGUYEN, KY NAM PHAM, TIEN DAT VU, QUYET THANG TRAN, XUAN THUC NGUYEN, THI HUYEN PHAM

Patent number: 10601617Abstract: A method may generate a demodulated sine component for a sequence of samples of a servo burst window of a position error signal using a sine weight look up table and generate a demodulated cosine component for the sequence of samples of the servo burst window of the position error signal using a cosine weight look up table. The sine weight and the cosine weight look up tables may have indexes representing a phase range. The method may generate a demodulated phase component signal and a demodulated amplitude component signal for the sequence of samples of the servo burst window of the position error signal based on the demodulated sine component and the demodulated cosine component using a Coordinate Rotation Digital Computer at least in part by iteratively rotating a vector based on the demodulated sine component and the demodulated cosine component and summing angular changes in the vector.Type: GrantFiled: May 8, 2018Date of Patent: March 24, 2020Assignee: Seagate Technology LLCInventors: Marcus Marrow, Jason Vincent Bellorado, Trung Thuc Nguyen

Patent number: 10220965Abstract: Described herein are systems and methods for attitude determination using infrared Earth horizon sensors (EHSs) with Gaussian response characteristics. Attitude information is acquired by detecting Earth's infrared electromagnetic radiation and, subsequently, determining the region obscured by Earth in the sensors' fields of view to compute a nadir vector estimation in the spacecraft's body frame. The method can be applied when two sensors, each with known and distinct pointing directions, detect the horizon, which is defined as having their fields of view partially obscured by Earth. The method can be implemented compactly to provide high-accuracy attitude within small spacecraft, such as CubeSat-based satellites.Type: GrantFiled: October 5, 2017Date of Patent: March 5, 2019Assignee: MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Tam Nguyen Thuc Nguyen, Kerri L.

Patent number: 8631388Abstract: Techniques for developing a graphical editor using an incremental development approach. Externally-stored descriptors are used to specify information on which a graphical editor engine operates to create a graphical editor. Developers can thus redefine the look and feel of the graphical editor by modifying these descriptors, effectively re-configuring the elements of visual models without changing the code of the graphical editor engine. Visual models for modeling a domain can be created and used, without first requiring the domain model to be defined.Type: GrantFiled: October 24, 2011Date of Patent: January 14, 2014Assignee: International Business Machines CorporationInventors: Jinchao Huang, Thuc Nguyen, Koi Chong Wong
