Beschreibung
Zusammenfassung:	A trigger including a carrier, a shuttle movably disposed on the carrier, an energy member disposed between the carrier and the shuttle, a degrade-on-demand trip member disposed to maintain potential energy in the energy member until activated. : A method for operating a downhole tool including sending a signal to the trip member of the trigger, degrading the trip member, converting potential energy stored in the energy member from potential energy to kinetic energy, and actuating the downhole tool with the shuttle. A wellbore system including a borehole in a subsurface formation, a string in the borehole, a trigger disposed within or as a part of the string.
