Patent number: 12526326Abstract: This disclosure describes, in part, techniques for sharing content associated with network applications. For instance, a user may want to share content for a network application, such as a game stream for a gaming application. As such, system(s) may launch a broadcasting session on a first virtual server and launch the network application on a second virtual server. The first virtual server may then receive content data representing states of the network application from the second virtual server. Additionally, the first virtual server may receive video data representing the user and/or audio data representing user speech from a user device. The first virtual server may then generate broadcasting data using the content data, the video data, and the audio data. After generating the broadcasting data, the system(s) may send the broadcasting data to one or more computing devices associated with a user account.Type: GrantFiled: August 2, 2024Date of Patent: January 13, 2026Assignee: Amazon Technologies, Inc.Inventors: David Guadalupe Goehring, Paul-Michel DeBlois, Mustafa Hakim, Timothy Chang, Raghunath Chirravuri, Sarah Kyung Kim, Jediah Conachan, Kathryn Lynn Fukuda, Keegan Robert Cox, Brian Fisher, Jared Haren, Lanvi Nguyen, Samuel Adam Salameh, George Tsipolitis, Alan Zambrano

Patent number: 7032578Abstract: A venturi mixing system mixes intake air with exhaust gases for exhaust gas recirculation (EGR) in an internal combustion engine. The venturi mixing system has a venturi disposed in a mixing conduit. The venturi is connected to an intake air conduit and a supply conduit. The venturi and mixing conduit form an annular cavity connected to an EGR conduit. The venturi forms a mixing chamber. One or more inset conduits connect to the venturi and extend into the mixing chamber. Each inset conduit has an end outlet and one or more side outlets. The venturi generates a lower pressure region in the intake air. The inset conduits generate a turbulence field in the lower pressure region. The inset conduits direct intake air into the turbulence field. The inset conduits direct exhaust gases through the end and side outlets into the turbulence field. The exhaust gases mix with the intake air in the turbulence field to form a combustion gas for combustion of fuel in the engine.Type: GrantFiled: September 21, 2004Date of Patent: April 25, 2006Assignee: International Engine Intellectual Property Company, LLCInventors: Zhengbai Liu, Laura M.

Publication number: 20060016272Abstract: Simultaneous pressure and position information is accurately measured in a sensor realized by utilizing first and second sensor elements that each exhibit a decreasing width over the length of the sensor element and that are arranged overlapping each other and in a substantially complementary orientation to one another with respect to the width so that the point of narrowest width of the first sensor element overlaps the point of the widest width of the second sensor element. Pressure applied to the sensor causes each sensor element to generate an electrical signal that is proportional to both the applied pressure and the surface area at the location of the applied pressure. As a result of the complementary orientation and overlapping for these sensor elements, the first and second sensor elements generate an asymmetric pair of signals that uniquely define the applied pressure by position and magnitude.Type: ApplicationFiled: July 26, 2005Publication date: January 26, 2006Inventors: Timothy Chang, Biao Cheng

Publication number: 20050268196Abstract: An efficient method and apparatus for characterizing circuit devices is disclosed. In one embodiment, multiple test patterns for testing a circuit device are stored in a tester. Each test pattern includes both test data and control data that defines at least in part a sweep point at which the circuit device is tested. Thus, the tester can generate stimulus vectors for multiple sweep points without requiring control system intervention. Pass/fail indicators, each of which represents pass/fail results associated with a sweep point, are derived from the test results and stored in a Fail Capture Memory. A pass/fail boundary of the DUT can be determined from the contents of the Fail Capture Memory.Type: ApplicationFiled: August 10, 2005Publication date: December 1, 2005Inventors: Timothy Chang, Donald Stark

Patent number: 6751886Abstract: An apparatus comprises a duct having a fluid outlet for fluid propelled through the duct and a container positions a substance for diffusion into the fluid through an opening. A movable valve selectively places the opening in fluid communication with the fluid in the duct and seals the opening to prevent introduction of the substance into the fluid. In a particularly advantageous embodiment the apparatus is a blow dryer in which a heating element disposed in the duct heats air flowing therethrough. The substance can be a fragrance or a conditioner introduced into the air stream. According to other aspects of the invention, the container is interchangeable with containers containing other substances, such as different fragrances, and is completely sealed when the blow dryer is not in use. In another embodiment, a container attached to the duct ejects the substance in a spray external of the duct proximate to the duct outlet.Type: GrantFiled: January 30, 2003Date of Patent: June 22, 2004Assignee: Vivrant, L.L.C.Inventors: Timothy Chang, Sherwood Forlee, Eugene Hans Kung, Kaijen Hsiao, Flavio Poehlmann-Martins
