摘要： An adapter for a conventional conductor locator allows the locator to additionally detect the presence of passive, electronic markers. The adapter includes an electronic marker locator and a wireless interface housed in a common body which may be releasably attached to the conductor locator. The electronic marker locator, which may comprise conventional circuitry, outputs a marker detection signal to the wireless interface, which conditions the signal so that it is compatible with the input sensor of the conductor locator. The wireless interface includes an output antenna which is positioned adjacent the input sensor of the conductor locator when the adapter is attached thereto. If the conductor locator is of the type which may receive test signals at different operating frequencies, then the wireless interface also includes a modulator to selectively convert the marker detection signal to one of these operating frequencies. The electronic marker locator portion of the adapter may also be selectively adjusted to detect different discrete marker frequencies. The adapter may operate in a sleep mode, wherein the output signal of the wireless interface is disabled, but the wireless interface may still alert the user to the presence of an electronic marker by an audible alarm.
摘要翻译： 用于常规导体定位器的适配器允许定位器另外检测被动电子标记的存在。 适配器包括电子标记定位器和容纳在公共主体中的无线接口，其可以可释放地附接到导体定位器。 可以包括常规电路的电子标记定位器向无线接口输出标记检测信号，该无线接口调节信号以使其与导体定位器的输入传感器兼容。 无线接口包括输出天线，当适配器附接到其上时，输出天线位于导体定位器的输入传感器附近。 如果导体定位器是可能在不同工作频率下接收测试信号的类型，则无线接口还包括调制器，用于选择性地将标记检测信号转换成这些工作频率之一。 还可以选择性地调节适配器的电子标记定位器部分以检测不同的离散标记频率。 适配器可以在睡眠模式下操作，其中无线接口的输出信号被禁用，但是无线接口可能仍然通过声音警报来警告用户电子标记的存在。
