Abstract: Systems and techniques for depositing organic material on a substrate are provided, in which one or more shield gas flows prevents contamination of the substrate by the chamber ambient. Thus, multiple layers of the same or different materials may be deposited in a single deposition chamber, without the need for movement between different deposition chambers, and with reduced chance of cross-contamination between layers.

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: Data streaming applications may need to provide high reliability, particularly depending on the nature of the data being streamed. A framework is described that allows a data streaming application to ensure high reliability both during update operations and during ordinary operations. A unique event ID count can be recorded that reflects messages being sent from a source to the streaming application. After an update and service restart, the count can again be collected to see if data is flowing through the streaming application as expected. Unique database record counts can be reviewed (e.g. after a restart or during ordinary operations) to ensure that no records are being unexpectedly dropped. Data content sampling can also be performed to see that any data transformations are functioning properly. Corrective actions (after a restart or during ordinary operations) can also be taken, including replay of database messages that are dropped, or sending an alert.

Abstract: Biosensing measurements (e.g., heart rate, pupil size, cognitive load, stress level, etc.) are communicated in the context of events that occurred concurrently with the biosensing measurements. The biosensing measurements and the contextual events can be presented in real-time or as historical summaries. Such presentations allow users to easily gain useful insights into which specific events triggered which specific physiological responses in users. Therefore, the present concepts more effectively communicate insights that can be used to change user behavior, modify workflow, design improved products or services, enhance user satisfaction and wellbeing, increase productivity and revenue, and eliminate negative impacts on user's emotions and mental state.

An acknowledgement that the update on each of the one or more worker nodes has completed is received, and the commits to the database by the one or more worker nodes is enabled.

Abstract: Systems and methods for reconciling location based on multiple computing device signals. For example, the computing system can obtain location datasets associated with freight carrier services from computing sources. The computing system can determine an expected signal pattern for a location associated with a freight transportation service.

The confidence score can represent the probability that the respective location dataset is associated with a load being transported for a freight transportation service. The computing system can determine a primary location dataset based on the confidence scores. The computing system can perform actions based on the primary location dataset.
