Bridge monitoring systems used in practice employ conventional cables to communicate sensor measurements to a centralized data acquisition unit. Cable based systems have high installation costs and leave wires vulnerable to ambient signal noise corruption. In addressing these inherent drawbacks, a modular wireless monitoring system is proposed. Such a system promises lower capital and installation costs noise simultaneously ensuring reliable communication between sensing units.A vibration-electric generator has been proposed to generate electricity from the vibrations of the bridge to power an acceleration. To assess the feasibility of this idea, a model of the power produced from the generator is presented. It is concluded that the output power would be sufficient to power an acceleration sensor. Wireless sensing is prosperous in bridge health monitoring.

In order to abate the effects from the background disturbance in the system of laser proximity fuze, such as the smoke, mist, rains, clouds, snow and other artificial disturbances, a device based on the "dual range gate" techniques is designed. It can eliminate the natural interferences and disturbance as the rounds with pulse laser proximity fuze flights in the atmosphere. And moreover its detecting ranges reach 10 meters. The device improves greatly the anti-disturbance performance of the pulse laser proximity sensors.
