Abstract: Remote user interface (UI) rendering effects provide increased privacy and efficiency in computer user input systems. In an aspect, an application specifies remote UI effects to be managed and rendered on UI elements separately from the application, such as by an effects component running outside of the application's operating system process. When user input indicates a preliminary interaction with a UI element, the remote UI effect can be rendered without the application's knowledge of the preliminary interaction, hence preserving a user's privacy from the application of preliminary UI interactions.

Abstract: Implementations of the subject technology provide a small, portable physical object for use in an extended reality system. The system may include a device that allows a user/wearer to interact with virtual representations of content such as stored data and/or applications overlaid on the user’s physical environment. The object has a unique identifier that is obtainable by the device or another device. The object may be an inactive device without any internal circuitry, a passive device with circuitry that is activated by another device, or an active device having its own processing circuitry and/or a display housed in the body of the object. The object can be associated with content displayed by the device to provide a user with a physical object that can be moved or manipulated to move, modify, transport, or store the content generated, stored, and/or displayed in an extended reality environment.

Abstract: Various implementations disclosed herein more accurately or efficiently determine to which of multiple potential virtual objects user input should be directed in a 3D graphical environment. In some implementations, this involves using a rule that accounts for the types of the virtual objects to which a particular event may correspond. For example, a direction of intent may be identified and a rule used to determine to which of multiple potential virtual objects to associate an event.

The extended reality system includes at least one device that is capable of determining the locations of other devices in the system. This device can manage continuous transfer of control between other devices in the system responsive to three-dimensional location-based user inputs, and/or can manage continuous transfer of control between one or more of the other devices and the device itself.

Abstract: Aspects of the subject technology relate to gaze-based control of an electronic device. The gaze-based control can include enabling an option to provide user authorization when it is determined that the user has viewed and/or read text associated with a request for the user authorization. The gaze-based control can also include modifying a user interface or a user interface element based on user views and/or reads. The gaze-based control can be based on determining whether a user has viewed and/or read an electronic document and/or a physical document.

Abstract: Implementations of the subject technology provide virtual anchoring for extended reality (XR) display devices. A device may generate an XR environment that includes computer-generated (CG) content for display relative to various physical objects in a physical environment. In order to position the CG content, an XR application may request a physical anchor object to which the CG content can be anchored. In circumstances in which the physical anchor object is not available in the physical environment, a virtual anchor and/or a virtual anchor object corresponding to the physical anchor object can be provided to which the CG content can be anchored.

Abstract: A method of steps for decanting a cryogenic fluid from a storage tank that is in fluid communication with a back pressure regulator and a decant dewar. A minimum pressure is set for the back pressure regulator and a cryogenic fluid is fed from the storage tank to the back pressure regulator. When the pressure of the cryogenic fluid exceeds the minimum pressure set for the back pressure regulator, the cryogenic fluid is fed to the decant dewar. This flow will continue until the storage tank is essentially empty. The gas generated by this depressurization will be fed to an exit valve where it can be flared or recovered by the operator for additional uses.
