Disclosed are techniques for performing an antivirus task in a mobile wireless device running an embedded operating system. In one embodiment, calls intended for an application programming interface (API) function code is redirected to an antivirus function code. The redirection to the antivirus function code may be performed by modifying a kernel structure to point to a modified entry list instead of an API entry list. The redirection to the antivirus function code may also be performed by modifying the API function code to allow the antivirus function code to execute before the API function code. The kernel structure or the API function code may be properly restored back to its original form. Software implementations of these techniques may be readily loaded and unloaded, and may not require re-installation of the embedded operating system.

A vertical-mount network remote power management outlet strip embodiment of the present invention comprises a long, thin outlet strip body with several independently controllable power outlet sockets distributed along its length. A power input cord is provided at one end, and this supplies AC-operating power to relays associated with each of the power outlet sockets. The relays are each addressably controlled by a microprocessor connected to an internal I2C-bus serial communications channel. The power-on status of each relay output to the power outlet sockets is sensed and communicated back on the internal I2C-bus. A device-networking communications processor with an embedded operating system translates messages, status, and controls between the internal I2C-bus and an Ethernet port, and other external networks.

A computer system and method that are useful for embedded operating systems, thin client computing applications and the like, protects memory blocks in a nonvolatile version of the system program used at startup (reboot), for example in flash memory. Write operations to protected memory blocks are intercepted. A potentially revised version of any attempted re-written block is maintained in RAM and can be revised further during runtime, the original protected block remaining unwritten. A restriction process flags when or whether a revised block in the RAM is to become permanent. During a write operation or at orderly system shutdown, the revised blocks that were marked are written over the protected blocks in the nonvolatile version. The process can be embodied using file and directory attributes in variably sized Ramdisk virtual drive in a Windows XP-embedded system, providing processes with read access to the original protected block as well as the revisions, enabling configuration changes and software installations without multiple reboots.

The present invention relates to a robot hybrid system application framework based on a multi-core processor architecture. In the robot system with ARM/X86 multi-core processor as the controller, multi-core parallel processing architecture of the ARM/X86 multi-core processor is used to run the robotic hybrid system application framework comprising real-time operating system, non-real-time operating system and system supporting frame in the whole robot controller, so as to provide improved operating system services. In this application framework, a real-time operating system runs independently in one ARM/X86 core, while several non-real-time operating systems run on other ARM/X86 cores. The operating systems occupy processor resources and peripherals separately and run robotic applications with different real-time requirements. The application program can be used as a unified robot operating system (ROS) application node.

A method and apparatus for the virtualization of appliances provides an embedded operating system (OS) which is included in the system boot ROM of a personal computer. When the system boots, the OS is launched and looks for all available virtual appliances from, for example, the following places: local USB, flash card, e.g. SD, xD, CF, CDROM/DVD, or other storage media; local hard disk storage; and the Internet, e.g. an appliance server. The user selects an appliance to use from the OS, whereupon the appliance is loaded and launched. If the selected appliance is not on a local storage, then it is downloaded, e.g. over the Internet from an appliance server. The downloaded appliance can be cached in local storage media such that, the next time it is needed, it need not be downloaded from the appliance server. The user can also elect to boot an operating system from the hard disk, if an operating system and hard disk are installed, or to power-off the system.

The specification relates to a process of cloning a master embedded system configured with a non-writable volume or partition that stores an embedded operating system, where the master system is configured to provide an overlay to store updates directed to the non-writable volume or partition. A flag in the master system is configured with a setting, where the configured flag is for indicating that the overlay is needed and has not been provided. After configuring the flag, a master image of the master system is created, where the master image includes the configured flag. A clone of the master system is created on a storage of another system based on the master image. Storage units may store images created with the process. Storage units may also store cloned systems produced with the images. A clone of the master system may be provided with an overlay based on the setting of the flag in the clone of the master system, where the overlay provides file-system level write functionality to the non-writable volume or partition of the clone system.

A highly-available computer system is provided. The system includes at least two computer subsystems, each including memory, a local storage device and an embedded operating system. The system also includes a communication link between the two subsystems. Upon the initialization of the two computer subsystems, the embedded operating systems communicate via the communications link and designate one of the two subsystems as dominant. The dominant subsystem then loads a primary operating system. As write operations are sent to the local storage device of the dominant system, the write operations are mirrored over the communications link to each subservient system's local storage device. In the event of a failure of the dominant system, a subservient system will automatically become dominant and continue providing services to end-users.

A real time operating system (RTOS) for embedded controllers having limited memory includes a continuations library, a wide range of macros that hide continuation point management, nested blocking functions, and a communications stack. The RTOS executes at least a first and second task and uses a plurality of task priorities. The tasks share only a single stack. The task scheduler switches control to the highest-priority task. The continuations library provides macros to automatically manage the continuation points. The yield function sets a first continuation point in the first task and yields control to the task scheduler, whereupon the task scheduler switches to the second task and wherein at a later time the task scheduler switches control back to the first task at the first continuation point. The nested blocking function invokes other blocking functions from within its body and yields control to the task scheduler.
