    摘要: A method of controlling a series turbocharger for an engine and a control system for the same includes a boost determination module determining a first predicted boost pressure for a first position of a variable geometry turbine when a high pressure turbine bypass valve is in an open position. The boost determination module determines a second boost pressure for a second position of the variable geometry when the high pressure turbine bypass valve is in the open position. A desired boost module determines a desired boost. A comparison module determines when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure. A bypass valve control module closes the high pressure turbine bypass valve when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure.

    摘要: An electronic device with a message encryption function that includes a message processing module for receiving or sending or reading encrypted messages. The message processing module is electrically connected to a configure interface module, a storage module and an encryption module. The message processing module checks whether an encryption code exists. Then the message processing module checks whether the message processing event is “reading a message”. If the processing module determines the processing event is “reading a message” the processing module determines whether the encrypted message has been read or not. If the encrypted message has been read the processing module directly transmits the encrypted message back and then displays the encrypted message. If the encrypted message has not been read the processing module decrypts the encrypted message to generate a decrypted message and transmits the decrypted message back and then displays the decrypted message in a clear-text manner.
