Latest Patents

Shibata's latest patents include a break-in detection sensor and a break-in detection system. The break-in detection sensor is designed to detect intrusions by climbing or jumping over a fence. It utilizes fiber Bragg gratings (FBGs) arranged at predetermined intervals along optical fibers. This system can detect intrusions over a wide area without the need for large-scale equipment. The reflected waves from the FBGs are processed by photodetection devices, which detect wavelength shifts caused by stress on the fence. A pattern recognition device then distinguishes between intrusions and other factors that may cause the fence to swing.

The break-in detection system incorporates both FBG-type sensors and OTDR-type sensors. This dual approach allows for the detection of intruders attempting to climb over or demolish a fence. The system uses a fiber optic cable that includes a sensor core wire and a LAN transmission core wire. This setup enables two-way transmission of video signals and control signals between a monitoring room and an ITV control device. The system is designed for reliability and maintenance-free operation.
