Abstract: A computer system displays a first object that includes at least a first portion of the first object and a second portion of the first object and detects a first gaze input that meets first criteria, wherein the first criteria require that the first gaze input is directed to the first portion of the first object in order for the first criteria to be met. In response, the computer system displays a first control element that corresponds to a first operation associated with the first object, wherein the first control element was not displayed prior to detecting that the first gaze input met the first criteria, and detects a first user input directed to the first control element. In response to detecting the first user input directed to the first control element, the computer system performs the first operation with respect to the first object.

Abstract: Various implementations disclosed herein include devices, systems, and methods that track a movement of an input device. For example, an example process may include determine a pose of a tracking device in a physical environment based on first sensor data from an image sensor. The process then may receive, from the tracking device, first positional data corresponding to a first relative positioning between the tracking device and an input device in the physical environment, where the first positional data is determined based on second sensor data obtained via a sensor on the tracking device. The process then may track movement of the input device in the physical environment based at least in part on the first positional data and the pose of the tracking device. The process then may determine an input for the electronic device based at least in part on tracking the movement of the input device.

Abstract: A computer system displays a first application user interface at a first location in a three-dimensional environment. While displaying the first application user interface at the first location in the three-dimensional environment, the computer system detects, at a first time, a first input corresponding to a request to close the first application user interface. In response to detecting the first input corresponding to a request to close the first application user interface: the computer system closes the first application user interface, including ceasing to display the first application user interface in the three-dimensional environment; and, in accordance with a determination that respective criteria are met, the computer system displays a home menu user interface at a respective home menu position that is determined based on the first location of the first application user interface in the three-dimensional environment.

Abstract: Tool for installing O-rings in an inner diameter of a structure includes a plurality of held in a spaced, fixed parallel relationship to one another. A plurality of guide surfaces are secured with and disposed between the plates. A selectively-actuable finger actuator is disposed to move a plurality of fingers generally radially between the plurality of plates. Each of the plates includes a slot, and a loading pin is configured to be received within the slots. When at least one O-ring is disposed about a plurality of guide surfaces proximal the periphery of the plates, and the loading pin is moved within the slots, the loading pin pulls a loop of the O-rings toward the plate axis. When the loading pin is removed, the finger actuator may be actuated to move the fingers in the generally radial direction to move the at least one O-ring radially outward from the plates.

Abstract: An insert for an engine block and systems, assemblies, components, and methods thereof can comprise a ring-shaped body having an inner surface and an outer surface opposite the inner surface. The inner surface can having one or more sealing grooves adapted to receive and retain respective sealing rings. A maximum outer diameter of the ring-shaped body can be defined by the outer surface and can be greater than a height of the ring-shaped body in a longitudinal direction of the ring-shaped body.

Abstract: A liner for a cylinder of an internal combustion engine can comprise a hollow cylindrical wall or body having an inner surface, an outer surface opposite the inner surface, and open top and bottom ends. The outer surface can be without any sealing grooves in at least a bottom portion thereof. A relatively thin portion of the wall or body can be provided below a thick portion of the wall or body, and may reach the bottom end of the wall or body. An angled transition can define a change in thickness from the thick portion to the thin portion.

Abstract: A system and method may provide standardized application programming interfaces that enable global entity-to-entity communications, such as to enable a process associated with one entity to access multiple systems at another entity. Some benefits of a global, standardized API-based entity-to-entity data exchange and integration platform include reduced cycle times by accelerating service delivery through automated and streamed data collection processes and an improved overall interface experience by embedding data collection processes into existing tools and improving accuracy by reducing manual data entry errors. For example, the standardized APIs may be used to generate a service request sent from a first service provider to a second service provider to ask the second service provider to provision a service to a customer of the first service provider.

Abstract: A method of initially operating an internal combustion engine including operating the engine in a start-up mode is provided. The start-up mode includes injecting at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots. An engine is provided including an electronic controller with a computer readable medium having a control algorithm recorded thereon, the control algorithm including means for commanding injection of a main fuel shot and at least two fuel pre-shots wherein a first of the fuel pre-shots is smaller in quantity than a last of the fuel pre-shots.

Abstract: An orbital vibrator apparatus has a base mounted on vibration isolation mounts. An armature plate is resiliently mounted to the base by three flexural spring elements. An armature of magnetically attracted material is mounted to the armature plate. A first electromagnet and a second electromagnet are mounted on the base at right angles to one another and in a spaced apart relationship to the armature. A source of single-phase alternating current is connected to the first electromagnet and the second electromagnet by way of a control circuit.

The phase shifting circuit shifts the phase of the alternating current by approximately ninety degrees. The first electromagnet is driven directly from the output of the voltage transformer and the second electromagnet is driven from the output of the phase shifting circuit.
