Claim Text:
1. An apparatus for attenuating a transient, said apparatus comprising: an input configured to receive an input signal; an output configured to connect to a driven device; a detector electrically connected to said input, said detector responsive to an amplitude of said input signal, said detector providing a detected signal when said amplitude of said input signal exceeds a first value; a switch operatively coupled to said detector, said switch having an actuated state in response to said detected signal, said switch electrically connected to said output such that said switch applies a low impedance across said output when said switch is in said actuated state; and an electrical connection between said input and said output, said electrical connection having an electrical propagation delay greater than a time interval for said switch to actuate after said input signal exceeds said first value at said input, whereby the transient is detected and said switch is actuated before the transient electrically propagates to said output.
