Abstract:
A control system for a target system including first and second terminals, said second terminal of said target system coupled with a power source, said control system comprising:a resettable switch including an input coupled with said first terminal of said target system, an output of said switch coupled with a current source/sink; and a current sourcing/sinking device including an input and an output, said output of said current sourcing/sinking device coupled with said first terminal of said target system and said input of said switch; wherein a sensing of a first event activates said switch to thereby activate said target system by causing flow of current from said power source to said second terminal of said target system, through said target system and said switch; wherein a sensing of a second event causes said output of said current sourcing/sinking device to draw current from said first terminal of said target system, thereby continuing the flow of current through said target system, the drawing of current by said output of said current sourcing/sinking device from said first terminal of said target system removing the flow of current through said switch thereby automatically resetting said switch while the target system remains activated.
