Abstract: This disclosure provides methods and systems for performing authentication in a virtual reality environment. In some implementations, the system receives a request for access to a virtual reality financial center requiring authentication from a user. The system can collect user identification information that identifies the user and verification information required to verify the user's identity via a virtual reality platform.

Abstract: Embodiments of the present disclosure generally relate to methods and materials for fabricating building materials and other components from coal. More specifically, embodiments of the present disclosure relate to materials and other components, such as char clay plaster, char brick, and foam glass fabricated from coal, and to methods of forming such materials. In an embodiment is provided a building material fabrication method. The method includes mixing an organic solvent with coal, under solvent extraction conditions, to form a coal extraction residue, and heating the coal extraction residue under pyrolysis conditions to form a pyrolysis char, the pyrolysis conditions comprising a temperature greater than about 500° C. The method further includes mixing the pyrolysis char with water and with one or more of clay, cement, or sand to create a mixture, and molding and curing the mixture to form a building material. Pyrolysis char-containing materials are also disclosed.

Abstract: Methods and systems described in this disclosure are directed at delivery of educational concepts for increasing the financial literacy of youths. In some embodiments, a mobile application program is disclosed that facilitates management of tasks assigned to youths, setting up a rewards program for participants that complete tasks successfully on time, integrating different types of data from various devices to determine whether an assigned task is successfully completed. In some embodiments, the disclosed platform can integrate with electronic payment systems managed by external third parties for rewarding youths on successfully completing the task.

Abstract: In one embodiment, a method includes receiving an instruction to transition to a first virtual reality (VR) environment of a first VR application, accessing attribute information of one or more real-world objects in a real-world environment proximate to a VR display device, determining, for each of the one or more real-world objects, one or more first mixed reality (MR) functionalities applicable to the real-world object based on its attribute information, and rendering, for one or more displays of the VR display device, the first VR environment with one or more MR objects corresponding to the one or more real-world objects, wherein each MR object comprises one of the first MR functionalities applicable to the corresponding real-world object.

Abstract: Aspects of the present disclosure are directed to defining an artificial reality environment (XRE) and controlling interactions between various artificial reality actors with a defined XRE schema. The XRE schema includes a set of definitions for an XRE, independent of type of artificial reality device. The definitions in the XRE schema can include standards for both interfaces and data objects. The XRE schema can define XR elements in terms of entities and components of a space, organized according to a hierarchy. Each entity can represent a real or virtual object or space, within the XRE, defined by a name and a collection of one or more components. Each component (as part of an entity) can define aspects and expose information about the entity. The XRE schema can specify structures that that allow actors (e.g., producers, instantiators, and consumers) to define and perform actions in relation to XRE elements.

Abstract: In one embodiment, a method includes displaying, for one or more displays of a virtual VR device, a first output image comprising a passthrough view of a real-world environment. The method includes identifying, using one or more images captured by one or more cameras of the VR display device, a real-world object in the real-world environment. The method includes receiving a user input indicating a first dimension corresponding to the real-world object. The method includes automatically determining, based on the first dimension, a second and third dimension corresponding to the real-world object. The method includes rendering, for the one or more displays of the VR display device, a second output image of a VR environment. The VR environment includes a MR object that corresponds to the real-world object. The MR object is defined by the determined first, second, and third dimensions.

Abstract: The present technology provides a system that enables a user to communicate with one of multiple devices in a network based on context information from another device in the network. The system includes a context manager configured to (1) receive context information from the multiple devices; (2) identify a subject-of-interest based on a user input; (3) determine a set of relevant context information based on the subject-of-interest and the received context information; and (4) transmitting the set of relevant context information to a target device to perform a task associated with the subject-of-interest. The context information managed by the present technology enables a user to conveniently interact with the multiple devices in the network without requiring the user to provide details of his/her instructions.

Abstract: Techniques are described for cross-device authorization using a wireless network connection. Computing device(s) may broadcast an identification signal indicating that the device is authorized to access a remote service, and is therefore available to provide an authorization token to a receiving device. The receiving device may determine one of the broadcasting device(s) to use for cross-device authorization. The receiving device may send a request, to the determined broadcasting device, for an authorization token to access the remote service. The broadcasting device may receive the request and transmit a message to a server device indicating that an authorization token is to be provided to the receiving device. Alternatively, the authorization token may be sent directly from the broadcasting device to the receiving device (e.g., over the wireless communication network). On receiving the authorization token, the receiving device may use it to access the remote service.

Abstract: One or more embodiments of the disclosure provide systems and methods for improving a user experience for performing transactions between potential buyers and sellers online via real-time communications. For example, a social marketplace system enables a potential buyer to initiate a real-time communication with a seller without the potential buyer having to provide contextual information regarding the item to the seller. In one or more embodiments, the social marketplace system provides a banner, in connection with the real-time communication, populated with structured data associated with the item that the potential buyer and the seller are discussing.

Abstract: The disclosure generally relates to baffle fuel dams and tank boundary fuel dams having a single-piece or two-piece construction. In one example, a baffle fuel dam is a single piece having slotted holes sized and spaced to accommodate for tolerance variations during installation. The baffle fuel dams also include a base angle that allows installation at multiple locations. The disclosure also relates to tank boundary fuel dams that include a two-piece configuration which incorporates slotted holes to accommodate tolerance variations and that are sized/spaced for different installation locations. The tank boundary fuel dams may also include a base angle that allows installation at multiple locations.
