Abstract: A cross reality system that provides an immersive user experience by storing persistent spatial information about the physical world that one or multiple user devices can access to determine position within the physical world and that applications can access to specify the position of virtual objects within the physical world. Persistent spatial information enables users to have a shared virtual, as well as physical, experience when interacting with the cross reality system. Further, persistent spatial information may be used in maps of the physical world, enabling one or multiple devices to access and localize into previously stored maps, reducing the need to map a physical space before using the cross reality system in it. Persistent spatial information may be stored as persistent coordinate frames, which may include a transformation relative to a reference orientation and information derived from images in a location corresponding to the persistent coordinate frame.

Abstract: A well system having a wellbore that intersects a subterranean formation, a valve station in the wellbore, and a primary controller on surface that communicates with the valve station using wireless telemetry. The valve station includes a valve member that controls a flow of fluid in the wellbore, an actuator for operating the valve member, and a valve controller that provides command signals to the actuator for positioning the valve member. The primary controller sends command signals that are receivable when the telemetry is operational. The valve controller is programmed to control operation of the valve actuator and valve member when telemetry is suspended and so that the valve station operates autonomously when out of signal communication with the primary controller and until signal communication is reestablished.

Abstract: A bi-directional valve with valve elements having compliant features biasing them together to maintain a sealing interface that defines a fluid communication barrier within the valve. Parting the valve elements from one another removes the sealing interface allow fluid communication across the valve elements. The valve includes a side port and a choke member that selectively blocks fluid flow through the valve when moved adjacent the side port and selectively opens the valve to fluid communication when moved away from the side port. The choke member remains adjacent the side port until the valve elements are spaced a distance apart greater than that at which valve erosion or fluid cavitation occurs.

Abstract: Disclosed herein are examples of ladar systems and methods where data about a plurality of ladar returns from prior ladar pulse shots gets stored in a spatial index that associates ladar return data with corresponding locations in a coordinate space to which the ladar return data pertain. This spatial index can then be accessed by a processor to retrieve ladar return data for locations in the coordinate space that are near a range point to be targeted by the ladar system with a new ladar pulse shot. This nearby prior ladar return data can then be analyzed by the ladar system to help define a parameter value for use by the ladar system with respect to the new ladar pulse shot. Examples of such adaptively controlled parameter values can include shot energy, receiver parameters, shot selection, camera settings, and others.

Abstract: Described herein is a system for hybrid denture fabrication. The system improve the efficiency of the fabrication process for both the dental service provider (e.g., dentist, dental surgeon, etc.) and the patient. A permanent hybrid prosthesis (e.g., the bridge and its reinforcing bar) can be fabricated within 24 hours of the surgical procedure using the system described herein. This makes it possible to deliverer the permanent hybrid prosthesis within 48 hours (or even within 24 hours) of the surgical procedure. Additionally, the system eliminates the need to provide the patient with a temporary denture following the surgery. Further, the system substantially reduces the patient's chair-time and/or the number of patient visits.

Abstract: An annulus safety valve assembly for controlling gas flow in a wellbore annulus that includes a passage, a check valve in the passage, and an actuator that is selectively changed between first and second states. The actuator is bi-stable, and requires no energy to remain in either state. When the actuator is put into one of the states, the check valve configuration is changed from one way flow to two way flow. Reconfiguring the check valve into the two way flow configuration vents lift gas from inside the annulus that is below the check valve.

Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. Both stored maps and tracking maps used by portable devices may have wireless fingerprints associated with them. The portable devices may maintain wireless fingerprints based on wireless scans performed repetitively, based on one or more trigger conditions, as the devices move around the physical world. The wireless information obtained from these scans may be used to create or update wireless fingerprints associated with locations in a tracking map on the devices. One or more of these wireless fingerprints may be used when a previously stored map is to be selected based on its coverage of an area in which the portable device is operating. Maintaining wireless fingerprints in this way provides a reliable and low latency mechanism for performing map-related operations.

Abstract: Systems and methods which utilize one or more social networking systems when creating, funding, and/or notifying a party of a transaction are provided. In accordance with one aspect, a money transfer transaction may be staged by a user whereupon a link corresponding to the staged transaction may be posted to one or more social networking services in order to allow for multiple users to access and fund the staged transaction. Additionally, in some aspects a user of a social networking service may generate a comment or post which then automatically triggers the staging of a money transfer transaction. Moreover, social networking services may be utilized to provide various notifications regarding money transfer transactions.

Abstract: A cross reality system enables any of multiple devices to efficiently and accurately access previously stored maps and render virtual content specified in relation to those maps. The cross reality system may include a cloud-based localization service that responds to requests from devices to localize with respect to a stored map. The request may include one or more sets of feature descriptors extracted from an image of the physical world around the device. Those features may be posed relative to a coordinate frame used by the local device. The localization service may identify one or more stored maps with a matching set of features. Based on a transformation required to align the features from the device with the matching set of features, the localization service may compute and return to the device a transformation to relate its local coordinate frame to a coordinate frame of the stored map.
