Patent number: 11936558Abstract: Systems and methods are provided for evaluation of networks and changes thereto using automated analysis of network models. The automated analysis can be used to determine how to implement and mutate networks efficiently and effectively, to determine whether and why network resources are unable to communicate with each other, and the like. Automated analysis can allow users (e.g., network administrators) to define networks and pose changes to networks using high-level policies (e.g., written in a declarative language), have those polices automatically translated to lower-level implementation operations for analysis, and in some cases have results of the analysis presented back to the users in an easy-to-understand form.Type: GrantFiled: December 10, 2021Date of Patent: March 19, 2024Assignee: Amazon Technologies, Inc.Inventors: Baihu Qian, Bashuman Deb, Justin Lin Hsieh, Daniel William Dacosta, Nick Matthews, Anoop Dawani, Omer Hashmi, Thomas Nguyen Spendley, Viktor Heorhiadi

Patent number: 11306895Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises a light engine unit that is surrounded on its perimeter by a reflective pan. A back reflector defines a reflective interior surface of the light engine. To facilitate thermal dissipation, a heat sink is disposed proximate to the back reflector. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the heat sink mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the heat sink out to the back reflector.Type: GrantFiled: November 24, 2020Date of Patent: April 19, 2022Assignee: IDEAL Industries Lighting LLCInventors: Mark Edmond, Dong Lu, Paul Pickard, Nick Nguyen, Gerald Negley, Gary David Trott

Patent number: 11209135Abstract: A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.Type: GrantFiled: September 25, 2020Date of Patent: December 28, 2021Assignee: IDEAL Industries Lighting LLCInventors: Nathan Snell, James Michael Lay, Nick Nguyen, Patrick John O'Flaherty

Patent number: 9328874Abstract: An LED lamp includes an elongated at least partially optically transmissive enclosure. The LEDs are mounted on an LED board. The enclosure has a support structure for supporting the LED board. The support structure is formed as one-piece with the enclosure and of an optical material. A pair of end caps are secured to the ends of the enclosure using a snap-fit connection. The end caps retain pins for connecting to a light fixture.Type: GrantFiled: June 30, 2014Date of Patent: May 3, 2016Assignee: Cree, Inc.Inventors: Randolph C. Demuynck, Nicholas W. Medendorp, Jr., John R. Rowlette, Jr., David Power, Nick Nguyen, Bart P. Reier, Daniel J. VanEpps, Jr.

Publication number: 20070048183Abstract: A method measures a property of a solution spectroscopically by placing a quantity of the solution into a cuvette and passing a light therethrough. A reservoir receives a quantity of the solution and bubbles are driven off prior to putting a sample therefrom into the cuvette for measuring.Type: ApplicationFiled: August 26, 2005Publication date: March 1, 2007Inventors: Nick Nguyen, Richard Jackson

Publication number: 20060269442Abstract: An occlusion minimizing connector connects a lumen in a lumen device to a source of sterilization fluid in an endoscope reprocessor. The connector has a sealing portion shaped to engage a surface on the lumen device. The sealing portion is formed of a resilient material biasing a sealing surface into contact with the surface on the lumen device. The biasing is such that the seal is maintained when pressure within the flow passage is below a predetermined level preventing leakage of the flow past the sealing portion. When pressure within the flow passage is above the predetermined level fluid leaks past the sealing portion to bathe the surface on the lumen device. Thus, the surface will not be occluded during a cleaning process.Type: ApplicationFiled: May 31, 2005Publication date: November 30, 2006Inventors: Nick Nguyen, Todd Morrison

Publication number: 20050132533Abstract: A door closure system for a vacuum sterilization chamber includes a mechanism to allow movement of the door with respect to the chamber at the hinge. An elongated slot on the door captures a fixed shaft to allow rotation of the door. A spring in the door operates against the shaft biasing the door toward the chamber. Forces applied by the hinge and by an opposite latch are normalized.Type: ApplicationFiled: December 28, 2004Publication date: June 23, 2005Inventors: Nick Nguyen, Doug Truong, Todd Morrison
