DETERMINATION DEVICE FOR WEAPON |
摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a determination device for weapons that sensing approach of a person who conceals weapon such as a cutting tool. <P>SOLUTION: The determination device KS determines whether a metal made of iron corresponds to weapon or not. The determination device KS includes an MI sensor SS detecting residual magnetization formed by the metal at detection resolution of pico-Tesla-order. A controller CP of the determination device KS estimates whether the metal can be used as the weapon or not, by determining a magnetic field distribution based on the residual magnetization detected by the MI sensor SS. The controller CP transmits an estimation result. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
