Patent number: 11473884Abstract: A kinetic energy vehicle (or warhead) has a divert thruster system and an attitude control system, both operatively coupled to receive pressurized gasses from a solid rocket motor that is operatively coupled to both systems. The divert thruster system may have three divert thrusters evenly spaced around a circumference of the vehicle, offset 120 degrees from each other. The divert thrusters are located at a longitudinal (axial) location along the vehicle at or close to a center of gravity of the vehicle. In addition the vehicle may have an aft axial thrusters that may be used in maneuvering the vehicle.Type: GrantFiled: January 22, 2020Date of Patent: October 18, 2022Assignee: Raytheon CompanyInventors: Huy P. Nguyen, Rob J. Fuentes, Michael Schmidt

Patent number: 11353301Abstract: A kinetic energy vehicle (or warhead) has a divert thruster system and an attitude control system, both operatively coupled to receive pressurized gasses from a solid rocket motor that is operatively coupled to both systems. The attitude control system may have two pairs of attitude control thrusters, with one of the pairs diametrically opposed from the other pair, on opposite sides of an end (such as a rear end) of the vehicle. The attitude control thrusters all have radial and circumferential components to their thrust, and various combinations of the attitude control thrusters may be used to achieve desired roll, pitch, and/or yaw.Type: GrantFiled: January 22, 2020Date of Patent: June 7, 2022Assignee: Raytheon CompanyInventors: Huy P. Nguyen, Rob J. Fuentes, Michael Schmidt

Patent number: 11189039Abstract: A system and method for star tracking includes: capturing an image of stars; detecting and selecting visible stars from the captured image; extracting features from the selected stars by forming a convex hull from the selected stars to generate a spherical polygon; computing the area and higher order moments of the spherical polygon; and pattern matching the extracted feature against a database of star catalog. The pattern matching includes matching the area of the spherical polygon to a plurality of polygon areas stored in the database and when the number of the matching candidates is more than one, matching a next extracted higher order moment with a respective higher order moment in the database, and repeating said matching of the next extracted higher order moment until the number of the matching candidates is equal to one.Type: GrantFiled: January 17, 2020Date of Patent: November 30, 2021Assignee: Raytheon CompanyInventors: Huy P. Nguyen, Dieter G. Krausser, Pradyumna Kannan

Patent number: 11061107Abstract: A target intercept system for guiding an interceptor to a target using passive ranging includes an EO/IR sensor that provides target azimuth and elevation angles, target irradiance, target area and target length. A dual Kalman Filter architecture is implemented where, prior to a target image becoming resolved, i.e., prior to endgame, a first Kalman Filter provides guidance as a function of target azimuth and elevation angles and target irradiance measurements. After the target image becomes resolved, i.e., at endgame, a second Kalman Filter provides guidance as a function of target azimuth and elevation angles, target area and, optionally, target length, instead. The dual Kalman Filter approach improves the estimates of time-to-go by optimizing the on-board EO/IR sensor measurements at the optimal times.Type: GrantFiled: April 5, 2018Date of Patent: July 13, 2021Assignee: Raytheon CompanyInventors: Huy P. Nguyen, Elliot Schwartz, Eric Blake, Pradyumna Kannan

Patent number: 8217911Abstract: A handheld device with a compact integrated touch panel is disclosed. A handheld device incorporating a touch panel display requiring electrical connections is reduced in size by incorporating electrical pathways within the support structure of the touch panel display, obviating the need for a flex circuit extension from the touch panel display for connection to the handheld device. A further reduction in size is obtained by providing an inherent visually homogeneous perimeter for the touch panel display by matching the colors of the conductive and dielectric materials, thereby eliminating the need for a bezel.Type: GrantFiled: January 27, 2009Date of Patent: July 10, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Shawn Gettemy, Huy P. Nguyen, Bill Webb, Lawrence Lam, Kean Wong

Patent number: 7880724Abstract: A handheld data processing device having three functional components assembled in a sliding configuration. A processor module is mechanically coupled to two sliding covers. The processor module houses circuits for performing the functions of data processing and may also include a display and input/output functionality. The two sliding covers provide protection for the processor module and may include input/output transducers such as a keypad, speaker or microphone. Embodiments of the handheld data processing device include a handheld computer, wireless telephone and handheld video display. Used as a telephone, the sliders may house a speaker and a microphone.Type: GrantFiled: December 15, 2006Date of Patent: February 1, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Huy P.

Publication number: 20100159984Abstract: A handheld computer is provided that includes a first module and at least a second module. The first module includes a processor and a display. The second module is slideably coupled to the first module so that it functions as a sliding cover that may effectively change the visible area of the underlying display. The handheld computer includes a sensing device coupled to the processor. The sensing device provides information to the processor regarding the relative position of the first module with respect to the second module. The information provided may be used to reconfigure the visual output of the display or to select a macro command presented on the display.Type: ApplicationFiled: March 2, 2010Publication date: June 24, 2010Applicant: PALM, INC.Inventors: Huy P.
