Abstract: Cross-environment rendering and user interaction support provide a seamless computing experience in a multi-operating system computing environment. Cross-environment rendering provides real-time display of applications running in a mobile operating system to be displayed within an environment of a desktop operating system. The mobile operating system and the desktop operating system may be running concurrently and independently on a shared kernel of a mobile computing device. A graphics server of the mobile operating system tears down and rebuilds the rendering context for each application as it composites the surface information. The rendering context may be established to match the resolution of the associated display, so that graphics will be appropriately rendered for that resolution. The mobile computing device may be a smartphone running the Android mobile operating system and a full desktop Linux distribution on a modified Android kernel.

Abstract: Cross-environment rendering and user interaction support provide a seamless computing experience in a multi-operating system computing environment. The multi-operating system computing environment may include a mobile operating system and a desktop operating system running concurrently and independently on a mobile computing device. The mobile operating system may be associated with a first user environment and the desktop operating system may be associated with a second user environment. Real-time display of applications running in the mobile operating system within the second user environment is provided by rendering the application through an extended graphics context of the mobile operating system. Application graphics for multiple applications are rendered into portions of a single graphics frame. The mobile computing device may be a smartphone running the Android mobile operating system and a full desktop Linux distribution on a modified Android kernel.

Abstract: A dual-screen user device and methods for revealing a combination of selected desktops and applications on single and dual screens are disclosed. Desktops and applications can be shifted between screens by user gestures, and/or moved off of the screens and therefore hidden. Hidden desktops and screens can be re-displayed by other gestures. The desktops and applications are arranged in a window stack that represents a logical order of the desktops and applications providing a user with an intuitive ability to manage multiple applications/desktops running simultaneously. One embodiment provides an annunciator window extending across both screens in a dual screen configuration. The annunciator window provides alerts, notifications, and statuses of the device in an increased area thereby enhancing viewability of the information in the window. The annunciator window can be expanded over a selected screen to view full contents of the window without having to minimize or close running applications.

Abstract: The present disclosure is directed to methodologies and devices for handling maximizing and minimizing of hierarchically related windows.

Abstract: Systems and methods for transfer of data including establishing two separate connections, the two separate connections including a high speed connection and a high integrity connection. Blocks of data are exchanged over the high speed connection while the high integrity connection facilitates communication of descriptor data regarding data received over the high speed connection. As such, the data transfer speed of the high speed connection is utilized while communication via the high integrity connection allows for data reliability features not provided by the high speed connection.
