Abstract (en)
[origin: WO2004010554A2] This invention relates to protective circuitry (12) for electrical initiation elements (10) and finds utility in preventing inadvertent functioning of electrical bridge-initiation elements, such as semiconductor bridges (SCBs), bridgewires, etc., by transient environmental electrical signals. The protective circuitry (12) of this invention comprises a timer portion (14) and a clamping portion (16) and is designed to divert from the electrical initiation element (10) at least a portion of an electrical signal received at the input nodes (10a, 10b) thereof for a suitable time interval that corresponds to the duration of an expected transient signal, which is typically significantly smaller than the duration of a proper initiation signal.
