Abstract: A mirror file system (MFS) is a virtual file system that links two or more folders (e.g., on Windows) or directories (e.g., on UNIX) to form a mirroring pair. The folders or directories can reside on a local memory device of a computing system, on a portable memory device, or in a folder or directory shared by a remote system. A graphical user interface (GUI) or user application creates or opens a file in the Active folder, and the MFS software module creates or opens the same file in a Passive folder which is not mounted on the same mount point as the Active folder. The Active folder receives a file operation from the application of the computer directly. Once the file operation is received by the Active folder, it is automatically replicated to the Passive folder. The MFS software module provides update options of sequential, parallel synchronous and asynchronous.

Abstract: A mirror file systems (MFS) is a virtual file system that links two or more file systems together and mirrors between them in real time. The file systems linked and mirrored through the mirror file system can be a local file system connected to a physical device, or a network file system exported by a remote system on a network. The mirroring mechanism is established by linking a file system to another file system on a single directory through an MFS mounting protocol. User applications perform normal file system operation and file/directory operation system calls like open, read, write and close functions from the pathname of either file system. When updates occur, such as a write operation, the MFS mechanism ensures that all data updates go to both the file systems in real time.

Abstract: A method and system for determining mobile phone strain is provided. The method includes the steps of determining if strain on a mobile phone housing and/or strain on a printed circuit board (PCB) within the mobile phone exceed a predetermined value. If the strain(s) values exceed the predetermined value an alarm may be sounded and the strain values may be stored in memory for later retrieval and/or analysis.

Abstract: A mirror file system (MFS) is a virtual file system that links two or more file systems together and mirrors between them in real time. When the MFS receives updated data from an application, all file systems linked by the MFS are updated in real time. The file systems linked and mirrored through the mirror file system can be a local file system connected to a physical device, or a network file system exported by a remote system on a network. The real-time mirroring mechanism provided by the MFS is transparent to user applications. The system administrator first sets up the mirroring mechanism by linking a file system to another file system on a single directory through an MFS mounting protocol. These two file systems and their files are linked together and become a mirroring pair. Both copies are owned by, and under the management of, the MFS. All access to files or directories in both file system go through the MFS.
