Filed: 2005-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio transmission device, a mutual authentication method and a mutual authentication program, which can perform mutual authentication with high concealability by a simple structure.  <P>SOLUTION: A user operates a remote control 20 to enter an authentication code shared by a plurality of radio transmission devices 10 performing radio transmission. A remote control transmission and reception unit 1 converts an infrared signal received from the remote control 20 to an electric signal, and extracts the authentication code from the electric signal. The authentication code is recorded on an authentication code record region 80 in a nonvolatile storage region 8. In an authentication communication mode, a radio unit 3 encrypts a radio unit MAC address with the authentication code used as a key, and transmits it. Further, the radio unit 3 decrypts the radio unit MAC address returned from the radio transmission device 10 of the opposite party of the transmission with the authentication code used as the key. The radio transmission device 10 obtains the radio unit MAC address of the opposite party of the transmission, and ends the authentication mode.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a crossing gate controller and a crossing gate controlling system and program which enable a reduction in the capacity of a power facility by reducing currents consumed by a crossing gate upon raising a crossing gate lever.  <P>SOLUTION: Timing for crossing gates 11a, 11b at the railcar entrance side to start raising crossing gate levers is shifted against timing for crossing gates 11c, 11d at the railcar exit side to start raising crossing gate levers by a given time to shift consumption current peaks against each other at the crossing gates 11a, 11b, 11c, 11d. This reduces a total current consumption peak to be lower than a peak that results when all crossing gates are raised simultaneously, thereby reducing the required power capacity of a rectifier 12a and a battery 12b of a power supply 12, which supplies power to the crossing gates 11a, 11b, 11c, 11d and other railroad crossing equipment. This capacity reduction leads to a smaller power supply 12, which enables a reduction in costs and space in installing the power supply 12.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
