Patent number: 11100713Abstract: Techniques for aligning a virtual object with a physical object in an Augmented Reality (AR) or Virtual Reality (VR) application are described. An electronic peripheral includes a first inertial measurement unit (“IMU”). A head mounted display includes a second IMU. An estimated attitude for the electronic peripheral is generated using data from the first IMU. An estimated attitude for the head mounted display is generated using data from the second IMU. An orientation of a virtual object is determined based on the estimated first and second attitudes, such that the virtual object is aligned with an object in a user's physical environment when the virtual object is displayed to the user. The virtual object is displayed on the head mounted display.Type: GrantFiled: August 17, 2018Date of Patent: August 24, 2021Assignee: Disney Enterprises, Inc.Inventors: Nathan D. Nocon, Amy E. Nelson, Michael P. Goslin, Seth A. Davis, Randall S. Davis

Patent number: 10832481Abstract: Techniques for providing multi-screen interaction in an interactive application. A primary device establishes an application session. The application session includes a virtual environment relating to a physical environment in which the primary user device is located. The primary user device is configured to display a graphical image relating to a primary virtual camera view of the virtual environment. A secondary virtual camera view of the virtual environment, relating to the primary virtual camera view, is determined. The primary user device transmits image data relating to the secondary virtual camera view from the primary user device to a secondary user device, which is configured to display a graphical image based on the image data. Responsive to receiving an interaction request from the secondary user device, the primary user device controls the application session based on the interaction request.Type: GrantFiled: August 21, 2018Date of Patent: November 10, 2020Assignee: Disney Enterprises, Inc.Inventors: Todd Michael Graham, John H. Crocker, Elliott H. Baumbach, Amy E. Nelson

Patent number: 10810747Abstract: Techniques for predicting a virtual camera view in an augmented reality (AR) or virtual reality (VR) application. A first change in position of a user device over a first time period is determined based on analyzing a plurality of frames of image data related to an AR or VR application. A dead reckoning calculation is used to predict a second change in position of the user device over a second time period, based on the first change in position and data received from an Inertial Measurement Unit (IMU) associated with the user device. A plurality of frames of image data are generated for display in the AR or VR application, based on the predicted second change in position of the user device.Type: GrantFiled: September 6, 2018Date of Patent: October 20, 2020Assignee: Disney Enterprises, Inc.Inventors: Todd Michael Graham, Amy E.

Patent number: 8053122Abstract: A system and method for starting up a fuel cell system are disclosed. Briefly described, an embodiment for starting an electrochemical reaction between a fuel and an oxidant during a start-up process includes a fuel cell stack operable to output a nominal voltage during a normal operating condition and operable to output a reduced start-up voltage during the start-up process, and includes at least one balance of plant (BOP) device that supports operation of the fuel cell stack, operable at a nominal output when sourced by the fuel cell stack at the nominal voltage, and operable at a reduced output when sourced by the fuel cell stack at the reduced start-up voltage.Type: GrantFiled: April 11, 2008Date of Patent: November 8, 2011Assignee: BDF IP Holdings Ltd.Inventors: Uwe M.

Patent number: 8015808Abstract: Power plant systems and processes are described that enable recovery of at least a portion of the fuel storage energy associated with a storage system for supplying fuel to the power plant systems. A first embodiment of an energy-recovery power plant system includes at least one fuel storage container and at least one expander that can receive fuel from the fuel storage container at a first pressure and provide the fuel to the power plant at a second pressure that is lower than the first pressure. A second embodiment of an energy-recovery power plant system includes a first conduit fluidly coupling the fuel storage container and the power plant for delivering fuel from the fuel storage container to the power plant and at least one regenerative thermodynamic cycle engine thermally coupled to the first conduit such that heat may be exchanged between the fuel and a working fluid for the regenerative thermodynamic cycle engine.Type: GrantFiled: August 17, 2006Date of Patent: September 13, 2011Assignee: G4 Insights Inc.Inventors: Bowie G. Keefer, Surajit Roy, Jean St.-Pierre, Amy E. Nelson, Shanna D. Knights

Publication number: 20110070511Abstract: Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump—dual loop cooling subsystem. During startup, one pump directs coolant through a startup coolant loop and after either the fuel cell stack or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop is then directed to the fuel cell stack. In an embodiment, coolant from the standard loop mixes with coolant in the startup loop after the predetermined threshold temperature is reached.Type: ApplicationFiled: November 30, 2010Publication date: March 24, 2011Applicants: DAIMLER AG, FORD MOTOR COMPANYInventors: Amy E.
