Abstract: A method includes obtaining computer-generated content associated with a first color characteristic. The computer-generated content is associated with a first region of a physical environment. The method includes detecting a second color characteristic associated with a second region of the physical environment different from the first region of the physical environment. The method includes, while the electronic device is in a first display rendering mode including the first and second color characteristics, determining that a display rendering mode change condition is satisfied, and accordingly changing the electronic device from the first display rendering mode to a second display rendering mode. Changing to the second display rendering mode includes changing the first region from the first color characteristic to a third color characteristic, or changing the second region from the second color characteristic to a fourth color characteristic different from the third color characteristic.

Abstract: In one implementation, a method of scene camera retargeting is performed by a head-mounted device (HMD) including one or more processors, non-transitory memory, a scene camera, and a display. The method includes capturing, using the scene camera, an image of a scene. The method includes determining, using the one or more processors, a depth of the scene. The method further includes transforming, using the one or more processors, the image of the scene based on the depth and a difference between a point-of-view of the scene camera and a point-of-view of a user. The method further includes displaying, on the display, the transformed image.

Abstract: Various implementations disclosed herein include devices, systems, and methods that enable improved display of virtual content in computer generated reality (CGR) environments. In some implementations, the virtual content is viewed by an observer and includes multiple content elements, each of which may be rendered at an independent rate based on a change of view of the observer.

Abstract: In one implementation, a method of frame rate extrapolation is performed by a device including one or more processors, non-transitory memory, a scene camera, and a display. The method includes capturing, using the scene camera, an image of a scene. The method includes displaying, on the display, the image of the scene at a first time. The method includes generating an extrapolated image by transforming, using the one or more processors, the image of the scene based on movement of the device, wherein the extrapolated image includes a first area including a first plurality of pixels having respective first pixel values based on a single depth and a second area including a second plurality of pixels having respective second pixel values based on a plurality of depths. The method includes displaying, on the display, the extrapolated image at a second time after the first time.

In addition, the measurement assembly includes a control assembly coupled to the force sensing assembly, the control assembly configured to receive the force measurement from the sensor. Further, the measurement assembly includes a housing configured to support each of the sensor assembly and the control assembly. The sensor is disposed on an external surface of the housing.

Abstract: A fan coil block of the present invention preferably includes a fan for drawing air and a cooling device for cooling air drawn by the fan. A flexible air handling system of the present invention preferably includes a fan coil block that is supportable overhead by an overhead support system. The present invention is also directed to an air handling method that includes the steps of providing an overhead support system for supporting overhead devices, defining a return air chase within the interior space of a building, and supporting a fan coil block above or within the return air chase using the overhead support system. The fan coil block draws and cools air from the return air chase and returns the cooled air to a plenum above the overhead support system.

Abstract: A pneumatic bioreactor having a containment vessel which includes a semi-cylindrical concavity defined by the vessel bottom. A mixing apparatus includes a rotational mixer rotatably mounted within the containment vessel about a horizontal axis. The rotational mixer has buoyancy-driven mixing cavities which are fed by a gas supply beneath the rotational mixer. The mixing apparatus extends into the semi-cylindrical concavity to substantially fill that concavity. The rotational mixer is divided into two wheels with outer paddles extending axially outwardly and inner paddles extending axially inwardly on either side of each wheel. Blades between the outer and inner paddles form impellers in the wheels to induce axial flow through the wheels in opposite directions. Stationary baffles fixed relative to the containment vessel are inclined toward the rotational mixer in the direction of rotation.

Abstract: A mixing system in a tank provides a flotation cell for froth collection of minerals such as metallic ores thereby separating such ores from other materials with which they are mined and enabling a concentrated ore component to be collected. The mixing system maintains particles containing the ores in a circulating liquid suspension in a contact zone where bubbles are discharged. Ore particles are attracted and attached to the bubbles. The bubbles rise and float to the top of the liquid for collection of the concentrated ores. The mixing system includes a radial flow impeller and an axial flow impeller which are attached for rotation on a common shaft, with the axial flow impeller below the radial flow impeller. The radial flow impeller is disposed in a space between a disc, which rotates with the radial flow impeller and another disc which is stationary, and may be a flange of a pipe around the shaft and extending above the surface of the liquid.

Abstract: A rotatably driveable enhanced-flow impeller system is provided for pumping at least one liquid in a tank through an outlet port thereof. A radial flow impeller has a first impeller face disposed proximate the bottom of the tank and proximate or extending into an inlet port for liquids in the tank bottom. The radial flow impeller has a plurality of blades with radially outermost blade tips terminating along a blade terminating circle. Disposed adjacent a second opposing face of the radial flow impeller is a radial flow extension plate which preferably extends radially outwardly along the second face by a radial distance beyond the blade terminating circle. The radial flow extension plate may be fixedly attached to the second impeller face.
