Abstract: The present invention relates to a method for recognizing a user-adaptive cursive script in a smart device based on state transition probability. The method is realized in a manner of allowing a recognizer to train a cursive script inputted by a user, making a chain code, generated from the cursive script, into a state transition probability matrix, providing the recognizer with each of cursive script discriminating factors (P1-P9) extracted from the state transition probability matrix and then outputting the recognition result, terminating the recognition of the cursive script, when the recognition result is normal, and receiving a request for characters intended by the user and allowing the recognizer to retrain the characters, when the recognition result is abnormal. Thus, a writing style of a user can be recognized quickly with a high accuracy, a fast writing style (cursive script) with stronger user-specific font characteristics can be recognized as an exact writing style and, in particular, the poor performance and use of current smart devices can be extended by improving the character recognition of the smart devices.

Abstract: The present invention relates to a method and an apparatus for synchronizing time of a separate operation system without disconnection by using GNSS common view information and precision time protocol information. The method and the apparatus for dual mode time synchronization of the present invention can perform time synchronization between separate operation systems continuously regardless of GNSS signal jamming and a failure of a GNSS receiver, by performing time synchronization between the separate operation systems by being converted to a precision time protocol information mode using the precision time protocol, if the GNSS signal jamming and the failure of the GNSS receiver occur, as time synchronization between the separate operation systems is performed in a GNSS common view information mode using the GNSS common view information.
