Publication number: 20240177364Abstract: To present augmented reality features without localizing a user, a client device receives a request for presenting augmented reality features in a camera view of a computing device of the user. Prior to localizing the user, the client device obtains sensor data indicative of a pose of the user, and determines the pose of the user based on the sensor data with a confidence level that exceeds a confidence threshold which indicates a low accuracy state. Then the client device presents one or more augmented reality features in the camera view in accordance with the determined pose of the user while in the low accuracy state.Type: ApplicationFiled: February 6, 2024Publication date: May 30, 2024Inventors: Mohamed Suhail Mohamed Yousuf Sait, Andre Le, Juan David Hincapie, Mirko Ranieri, Marek Gorecki, Wenli Zhao, Tony Shih, Bo Zhang, Alan Sheridan, Matt Seegmiller

Patent number: 11997426Abstract: A system for conducting a video conference and methods for making and utilizing the same. The system can generate a first virtual stage for a first participant in the video conference by selecting one or more items of personal information associated with the first conference participant and disposing the selected personal information items in a predetermined arrangement. The first virtual stage can be transmitted with a first visual image of the first conference participant to a computer system associated with a second conference participant for visual presentation during the video conference. The system advantageously can enable the computer system associated with each conference participate to visually present a visual image with an associated virtual stage for each of the other conference participants.Type: GrantFiled: July 18, 2022Date of Patent: May 28, 2024Assignee: Warmly, Inc.Inventors: Max Greenwald, Carina Boo, Alan Zhao, Valeria Yermakova, Scott O'Connor, Zack Zeyu

Publication number: 20240169036Abstract: System and method for managing health and safety protocols for occasions, including validation of health verification requirements, asynchronous communication, and generation of multi-factor health credentials. All components of the system can be configured within an integrated graphical user interface (GUI). These components, or subsystems, include a health verification subsystem to indicate one or more health verification requirements for attending the occasion, an occasion communication subsystem to manage communication with prospective visitors to the occasion, and an occasion access subsystem to generate electronic passes to the occasion for prospective visitors who comply with the health verification requirements. Health information provided by a prospective visitor is verified, a visitor/occasion specific QR code is generated and sent to the visitor in an email message.Type: ApplicationFiled: November 17, 2022Publication date: May 23, 2024Applicant: Salesforce, Inc.Inventors: Alan Davies, Shawn Butterfield, Sai Lakshminaraayana, Ganbaatar Arslanbaatar, Kevin Lun, Jianwu Zhao

Publication number: 20240056730Abstract: A ceiling-mounted microphone array enclosure includes a room panel and a top panel. The room panel includes a border of solid material that surrounds a central sound permeable area having sound permeable perforations. The top panel is connected to the room panel through connectors arranged along the border of solid material. The top panel can have sides and be connected to the room panel such that there is a gap to permit improved airflow, or sides of the top panel can connect directly to the bottom panel without a gap. A microphone array and other electronic components can be arranged within the enclosure and then ceiling mounted within a ceiling grid. Multiple differently sized room panels can be manufactured in such a way that they can connect directly to the top panel. To reduce manufacturing costs, each of the top panels can be manufactured having the same size and design.Type: ApplicationFiled: August 7, 2023Publication date: February 15, 2024Inventors: Derek Louis Graham, Pichet Ong, William Deberard, Feng (Alan) Zhao

Patent number: 11202701Abstract: A stent for placement in a blood vessel with a wall having an aneurysm including an endovascular graft having a first end, a second end, and a tubular body that is expandable and extends from the first end to the second end. The stent also includes a coagulation apparatus attached to the tubular body between the first and second ends. The coagulation apparatus has a frame and a coagulant attached to the frame. When the stent is deployed within the blood vessel, the tubular body extends across the aneurysm and expands at the first and second ends to seal against the wall of the blood vessel such that blood is channeled across the aneurysm through the tubular body such that a pocket of blood is defined external to the tubular body. The frame expands into the pocket to orient the coagulant therein and promote coagulation of blood within the pocket.Type: GrantFiled: June 30, 2017Date of Patent: December 21, 2021Assignee: Washington UniversityInventors: Eric C. Leuthardt, Greg Zipfel, Colin Derdeyn, Chandu Vemuri, Philip V. Bayly, Guy Genin, Katie McCoy, Junwoo Suh, Yuni Teh, Alan Zhao, Donald Elbert

Patent number: 5931052Abstract: An improved torsional vibration isolator assembly for an engine is provided which includes a non-linear spring device which effectively minimizes the transmission of torsional vibrations to the engine's gear train throughout all engine operating frequencies and conditions while limiting relative movement between the engine's crankshaft and crank gear so as to maintain timing error within acceptable limits. The improved torsional vibration isolator is designed to absorb torsional vibrations transmitted from the crankshaft so as to substantially isolate the entire engine gear train, including the crank gear, from the torsional vibrations throughout all engine operating conditions and frequencies, including at and below the natural frequency, i.e. crank resonance, of the crankshaft. The crank gear isolator includes resilient elements positioned in cavities formed between engaging projections formed on inner and outer rings of the assembly.Type: GrantFiled: June 20, 1997Date of Patent: August 3, 1999Assignee: Simpson International (UK) Ltd.Inventors: Alan Zhao, Charles E. Long, Dennis R. Tibbetts, Jeffrey D. Saueressig, Thomas E. Reinhart

Patent number: 5875752Abstract: An improved engine gear drive train arrangement is provided which effectively minimizes the crankshaft torsional vibrations at the location of the gear train, for engines with a front gear train. A flywheel is resiliently connected to the rear end portion of the crankshaft so as to resiliently connect a driven unit to the crankshaft. An extra inertial device is connected to the front end portion of the crankshaft and includes an inertia so selected as to cause a nodal point of the first torsional vibration mode of the crankshaft to be located in the vicinity of the crank gear to minimize the amplitude of torsional deflection of the crankshaft at the crank gear. Also, the device for resiliently connecting the flywheel to the rear end portion of the crankshaft may include resilient members positioned in cavities formed by engaging rings.Type: GrantFiled: June 16, 1997Date of Patent: March 2, 1999Assignee: Cummins Engine Company, Inc.Inventors: Alan Zhao, Thomas E. Reinhart, Kwin R. Abram, Mark A. Zen Ruffinen, Paul A. Hayes
