Abstract:
1. An energy attenuating device with the dynamically adaptive damping feature, the energy attenuating device comprising: a first variable resistor having positive resistance effect, one end of the first variable resistor serving as a first input pin; a second variable resistor having negative resistance effect and connected to the first variable resistor in series, one end of the first variable resistor serving as a second input pin; a variable capacitor connected to the first input pin; a variable inductor connected the variable capacitor in series, wherein the variable inductor further connects to the second input pin; and a thermopile connected to the variable inductor in parallel; wherein when a voltage shock occurs across the first input terminal and the second input terminal, an impedance of the thermopile increases so that a shortcut is formed by the first and second variable resistors to allow the current of the voltage shock firstly flows through the first and second variable resistors; the resistance of the first variable resistor subsequently increases due to the positive resistance effect to restrict the current, whereby the current subsequently passes through the variable capacitor and the variable inductor; since the current of the voltage shock alternately passes through either the first and second variable resistors or the variable capacitor and inductor, the voltage shock is attenuated.
