A virtual mobile infrastructure performs client-side rendering by intercepting and redirecting screen data for generating a screen image of a remote mobile operating system from a server computer to a mobile client device. The mobile client device receives the screen data and generates the final screen image of the remote mobile operating system. The screen data include drawing application programming interface (API) calls to generate surfaces for applications running on the remote mobile operating system and data for compositing the surfaces together. The mobile client device makes the drawing API calls to generate the surfaces and generates the final screen image of the remote mobile operating system by compositing the surfaces in accordance with the compositing data.

Client-side rendering for virtual mobile infrastructure

A virtual mobile infrastructure for mobile devices includes mobile client devices and a server computer running remote mobile operating systems. The remote mobile operating systems share the same kernel, and are each implemented on a container. A mobile client device running a mobile operating system, which may be the same as or different from the remote mobile operating systems, may access one of the many remote mobile operating systems on the server computer.

Virtual mobile infrastructure for mobile devices

A virtual mobile infrastructure includes a mobile client device running a local mobile operating system and a server computer running a remote mobile operating system. The mobile client device displays a screen image of the remote mobile operating system. User text inputs for a remote application running on the remote mobile operating system are received by way of a touchscreen keyboard of a local input method editor (IME) of the local mobile operating system. The user text inputs are transmitted from the mobile client device to the server computer, where the text inputs are provided to the remote application by a virtual IME of the remote mobile operating system.

Systems and methods for providing user inputs to remote mobile operating systems

Techniques for replacing ROM-based (Read-Only Memory) DLLs (Dynamic Link Libraries) in a Windows CE type embedded operating system such that the target DLL is replaceable by the hook DLL, and the target DLL is callable by the hook DLL but not callable directly by any other applications after loading of the hook DLL. The techniques enable replacement irrespective whether the hook DLL and the target DLL have the same name and irrespective of which DLL is loaded first. The techniques change the file name of the target DLL in a list of loaded DLL modules by a trusted program that executes in the full kernel mode.

Dynamic linking library (DLL) replacement in an embedded operating system environment

One embodiment relates to a computer-implemented method for generating difference data between reference and target files. A difference engine implemented using a computer receives the reference and target files. The difference engine performs a first procedure to generate difference data representing the difference between the reference and target files if the size of the reference file is less than a first threshold size. The difference engine performs a second procedure to generate the difference data if the size of the reference file is less than a second threshold size and greater than the first threshold. The difference engine performing a third procedure to generate difference data if the size of the reference file is greater than the second threshold size. Other embodiments relate to apparatus for generating difference data between reference and target files and for reconstructing the target files from the reference files using the difference data.
