Abstract: An interactive multi-media information and communication system translates an intelligible data stream with discrete elements into one or more logically derived output data streams. The discrete data elements are analyzed by real-time dictionary look-up processing procedures to determine context, application and rule settings. The outcome of the analysis is used to determine if the input data element is to be discarded, or if one or more output elements are to be selected and presented in one or more output data streams.

Abstract: A method of protecting memory locations in an embedded system using a write filter. The method includes the steps of starting a write filter that intercepts writes to the protected memory locations and stores the writes in a cache; starting a state machine with a change state and a normal state; upon starting the state machine, entering the change state when an indication is present that data needs to be persisted to the protected memory otherwise entering the normal state; in the normal state identifying critical writes to the protected memory and creating at least one update file containing the changes in such writes; and in the change state, applying the changes in the update file and rebooting the system in a manner that persists the changes to the protected memory.
