Patent ID: 7154732

Claim:
A squib firing system, comprising: a squib load; a system power source for generating a first voltage; and a squib firing device in electrical communication with said system power source to receive the first voltage, said squib firing device operable to be switched between a first plurality of modes including an armed mode, said squib firing device including a battery source for generating a second voltage, and a power supply in electrical communication with said battery source to receive the second voltage, wherein, in response to said squib firing device being switched to the armed mode and in response to an absence of said squib load being applied to said squib firing device, said power supply implements an analog OR of the first voltage and the second voltage to yield and store a squib firing power, and wherein, in response to said squib firing device being switched to the armed mode and in response to said squib load being applied to said squib firing device, said power supply discharges the squib firing power to establish a flow of a squib firing current through said squib load, the squib firing current for firing said squib load.
