    • This invention serves as a method and apparatus for delivering power to a series of remote sensors in an on hull sensor grid for the purpose of biasing the active circuitry on the sensors. It requires no physical connection between the source of power and the sensor. It works by delivering electrical energy across the insulating gap that separates the sensor from the hull by means of a displacement current. In particular, the method and device include a conducting layer interposed between inner and outer decouplers and a ground plane interposed between a bonding layer and the inner decoupler. An application of alternating current to the ground plane will activate the conducting layer and provide power to the sensors at a location of the outer decoupler. The inner decoupler acts as a capacitor and the ground plane further provides an electrical path back to the hull.
    • 本发明用作向船上传感器网格中的一系列远程传感器传送电力的方法和装置,用于偏置传感器上的有源电路。 它不需要电源和传感器之间的物理连接。 通过将电能传递通过位移电流将传感器与船体分隔开的绝缘间隙起作用。 特别地,该方法和装置包括介于内部和外部解耦器之间的导电层和插入在接合层和内部解耦器之间的接地平面。 将交流电施加到接地平面将激活导电层并且在外部解耦器的位置处向传感器提供电力。 内部去耦器充当电容器,并且接地平面进一步提供回到船体的电路径。
