Abstract: PROBLEM TO BE SOLVED: To provide a technique for reliably transferring a synchronization frame between network devices even if congestion, or the like in a network occurs since the network devices cannot be synchronized in cycle type transfer communication when the synchronization frame is not received regularly. SOLUTION: The network device arranges the synchronization frame for synchronizing network devices in the network in the first period of each cycle for transfer. The network device has: a cycle timer for measuring time in the cycle; and a synchronization management section for stopping the transmission of the frame for a prescribed period to the next cycle in each cycle, based on information from the cycle timer.

Abstract: PROBLEM TO BE SOLVED: To provide optical communication equipment capable of constructing an in-vehicle communication protocol of a control system LAN by an optical communication system.
SOLUTION: An optical signal transmitted from an ECU 1 transmits on a POF is distributed to a POF 13 by a first optical coupler 15, transmits the POF 13 in the direction of an arrow, is distributed by a fourth optical coupler 15 via a second optical coupler 15 and a third optical coupler 15, transmits a POF, and is received by an ECU 3. An optical signal transmitting the POF 13 is distributed by the first optical coupler 15 and is transmitted again to the ECU 1. In this case, the optical signal transmitting the POF 13 attenuates down to, for example, -20.0 dBm upon passing through the fourth optical coupler 15, and further attenuates by 3 dB at the first optical coupler 15 to be -23.0 dBm. Since this signal level is smaller than -22.0 dB being the sensitivity of an optical light reception part of the ECU 1, the signal cannot be received by the ECU 1.

SOLUTION: The information communication system is comprised of an electronic key for controlling a vehicle function, based on radio communication to and from the on-vehicle machine, and a portable terminal held by the vehicle owner. The electronic key has imparted thereto a function of monitoring a remaining amount of a battery of itself, and has a DCM mounted thereon, for exchanging data to and from a center via a communication circuit. The electronic key carries out determination as to whether or not the remaining amount of the battery falls to or below a predetermined value that is higher than a residual amount of the battery, capable of performing radio communication to and from the on-vehicle machine once. If the answer is affirmative, a notification that the remaining amount of the battery of the electronic key is lowered is transmitted from the DCM via the center to the portable terminal, to thereby notify the vehicle user.
