摘要： An integrated, flexible interrogator-coil circuit provides security for the type of lock opened by a key that transmits a coded signal to an interrogator circuit associated with the lock. When the key is inserted into the lock, a coil in the key is brought into proximity with an energized coil associated with the lock. The resulting current induced in the key's coil causes the key to transmit the coded signal. If the coded signal is recognized by the lock's interrogator circuit, the key opens the lock. The lock coil is an etched metallic spiral on a loop portion of the circuit board and the interrogator circuit components are mounted on a base portion of the circuit board on which is etched a metallic circuit pattern. The integrated interrogator-coil circuit is faster and more economical to manufacture. Because the circuit is on a flexible circuit board, it can be made a part of the lock assembly itself, thus facilitating use of this type of security system. The invention is particularly useful in securing the ignition systems of vehicles, although it can be used for other applications.

摘要翻译： 集成的，灵活的询问器线圈电路为通过将编码信号发送到与锁相关联的询问器电路的键打开的类型的锁提供安全性。 当钥匙插入锁中时，钥匙中的线圈与与锁相关联的带电线圈接近。 在键盘的线圈中产生的电流使得键传送编码信号。 如果编码信号被锁的询问器电路识别，则钥匙打开锁。 锁定线圈是在电路板的环路部分上的蚀刻的金属螺旋，并且询问器电路部件安装在蚀刻金属电路图案的电路板的基部上。 集成询问器线圈电路更快，制造更经济。 因为电路在柔性电路板上，所以它可以被制成锁组件本身的一部分，从而便于使用这种类型的安全系统。 本发明特别可用于固定车辆的点火系统，尽管它可以用于其他应用。
