    摘要： Maintenance information is collected by a sensor on an electric power cable installed in a manhole. The information is transmitted to a radio transmitter which is positioned in a vicinity of a bottom plane of an inner lid in an opening of the manhole. The information is transmitted by the radio transmitter, and received by a receiving antenna mounted on a bottom plane of the inner lid. On a top plane of the inner lid, an electrode, a connecting lead or a transmitting antenna is provided to be connected to the receiving antenna by an impedance matching circuit. The information is supplied to an outer lid in the opening of the manhole by the opening of the manhole by the electrode using a spatial coupling capacitance relative to the outer lid, or the connecting lead directly connected to the outer lid. Thus, the information is transmitted as a radio signal by the outer lid functioning as an antenna. Otherwise, the information is radiated below the outer lid by the transmitting antenna. Thus, the radiated information is leaked via the outer lid to the exterior of the manhole.

    摘要： An optical fiber 1 includes a core 11 and a cladding material 12. In a collision detection optical fiber sensor 100, a plurality of linear members 2 and 3 are twisted around an outer periphery of the cladding material 12 of the optical fiber 1. An elastic member 6 of the liner member 2 has an elasticity different from that of an elastic member 7 of the first linear member 3. The hardness of the elastic member 6 is lower than that of the elastic member 7. A rubber hardness difference measured by a durometer type A according to a JIS K6253 between the elastic member 6 and the elastic member 7 is not less than 10.

    摘要： An optical fiber sensor can be interposed between a bumper reinforcement and a load transmitting plate to extend in the direction of width of a vehicle along with the bumper reinforcement. In this case, when a change does not occur substantially in an immediately previous predetermined period in an output voltage of a light emission amount of the optical fiber sensor, a feedback control is performed in such a way that the change becomes a level of zero of the output voltage of the optical fiber sensor. In contrast, when a change in the output voltage is not substantially zero, the immediately previous state of emission of light is maintained. Accordingly, it is possible to effectively compensate a zero point shift caused by a temperature change or/and an aging degradation of the optical fiber sensor.
