摘要 |
<p>A wellbore tool comprising a power supply (204), an electrical load (208), a receiving unit (206) configured to passively receive a triggering signal, and a switching system (202) electrically coupled to the power supply, the receiving unit, and the electrical load, wherein the switching system is configured to selectively transition from an inactive state to an active state in response to the triggering signal, from the active state to the active state in response to the triggering signal, or combinations thereof, wherein in the inactive state a circuit is incomplete and any route of electrical current flow between the power supply and the electrical load is disallowed, and wherein in the active state the circuit is complete and at least one route of electrical current flow between the power supply and the electrical load is allowed.</p> |
