  • Publication number: 20120113773
    Abstract: A CAN driver receives vehicle information sent onto CAN. A diagnosis information acquiring module monitors whether an operation of a diagnosis record ECU itself is normal or not and thus generates diagnosis information. A timestamp information generating module generates timestamp information A per sec and generates timestamp information B in which a time difference from the generation timing of the timestamp information A is expressed on the unit of 1/100 sec. A diagnosis record module, each time the timestamp information generating module generates the timestamp information A, transfers a first type record containing the timestamp information A and the diagnosis information generated at this point of time to a memory manager, and transfers a second type record containing the vehicle information and the timestamp information B generated at this point of time to the memory manager.

  • Publication number: 20120051743
    Abstract: In an optical network system a carrier light propagates along a transmission line. A control light generator included in an optical multiplexing apparatus generates a control light obtained by modulating an intensity-modulated light by a data signal. A multiplexer combines the control light with the carrier light for modulating the carrier light in a nonlinear optical medium in the transmission line by the control light. The carrier light which propagates along the transmission line is modulated in the nonlinear optical medium on the basis of the control light.
