Abstract: A dual-screen user device and methods for revealing a combination of desktops on single and multiple screens are disclosed. Selected desktops and/or running applications are displayed on dual screen displays. 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 yet 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 user gesture launches an applications management window that provides visual indications of all of the applications and desktops running at the time, applications/desktops displayed on the screens. Other gestures can rearrange the order of all of the applications and desktops in the window stack.

Abstract: A mobile computing device with a mobile operating system and desktop operating system running concurrently and independently on a shared kernel without virtualization. The mobile operating system provides a user experience for the mobile computing device that suits the mobile environment. The desktop operating system provides a full desktop user experience when the mobile computing device is docked to a second user environment. Cross-environment rendering and user interaction support provide a seamless computing experience in a multi-operating system computing environment. The seamless computing experience includes mirroring the active user interaction space of the mobile operating system to a display of a user environment associated with the desktop operating system. 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: Methods and devices for presenting a virtual keyboard are provided. More particularly, in connection with a multiple screen device, a virtual keyboard can be presented in a first mode using portions of both of the screens. In a second mode, the virtual keyboard can be presented using all of one of the screens. Movement between the different modes can be effected by rotating the device between a dual portrait orientation, corresponding to the first mode, and a dual landscape orientation, corresponding to the second mode. More particularly, with the screens of the device in a landscape orientation, one screen can be devoted to present the virtual keyboard while the other screen remains available to present other information.

Abstract: A mobile computing device with a mobile operating system and desktop operating system running concurrently and independently on a shared kernel without virtualization. The mobile operating system provides a user experience for the mobile computing device that suits the mobile environment. The desktop operating system provides a full desktop user experience when the mobile computing device is docked to a secondary terminal environment. Applications of the desktop operating system communicate with applications and services of the mobile operating system through a cross-environment communication framework. The cross-environment communication framework may include interfaces to remotable objects allowing processes in the mobile operating system and processes in the desktop operating system to share memory in a thread-safe manner. 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: 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.
