    • A surface-conforming obscured feature detector includes a plurality of sensor plates, each having a capacitance that varies based on the dielectric constant of the materials that compose the surrounding objects and the proximity of those objects. A sensing circuit is coupled to the sensor plates 32 to measure the capacitances of the sensor plates. A controller is coupled to the sensing circuit to analyze the capacitances measured by the sensing circuit. One or a plurality of indicators are coupled to the controller, and are selectively activated to identify the location of an obscured feature behind a surface.
    • 表面一致的遮蔽特征检测器包括多个传感器板,每个传感器板具有基于构成周围物体的材料的介电常数和这些物体的接近度而变化的电容。 感测电路耦合到传感器板32以测量传感器板的电容。 控制器耦合到感测电路以分析由感测电路测量的电容。 一个或多个指示器耦合到控制器,并且被选择性地激活以识别表面后面的被遮蔽特征的位置。
