    • Handling or removal of a pair of defibrillator electrode pads from their package is detected in order to effectively time the issuance of prompts to guide the user. One plate of a capacitor is embedded in the package, the electrode pads and lead wires serving as the other plate. Impedance across the capacitor in an alternating current circuit is monitored to detect an increase in the distance between the pads and the package. The impedance level is determined, in a low-cost hardware solution, by rectifying and then integrating an output voltage of the capacitor to produce a voltage signal whose magnitude attenuates as the pads are handled or removed. In one embodiment, the above methodology is time-division multiplexed with an alternative process that identifies handling or removal based on pad-to-pad impedance. In a further embodiment, the capacitive configuration is replaced with an inductive one.
    • 检测到一对去纤颤器电极垫从其包装中的处理或去除,以便有效地发出引导用户的提示。 电容器的一个板嵌入封装中,电极焊盘和引线用作另一个板。 监视交流电路中的电容器两端的阻抗,以检测焊盘和封装之间的距离的增加。 在低成本的硬件解决方案中,通过对电容器的输出电压进行整流,然后对电容器的输出电压进行积分来确定阻抗电平,以产生电压信号,该电压信号的幅度随着焊盘被处理或去除而衰减。 在一个实施例中,上述方法与基于焊盘对焊盘阻抗识别处理或移除的替代处理进行时分复用。 在另一个实施例中,电容配置被替换为电感配置。
