#automatic activation
- To self-trigger — To go into operation, start, or activate automatically or autonomously on its own, as a result of meeting a predefined condition, an internal impulse, or a sensor detecting an external stimulus, without the manual intervention of an operator. In engineering, it describes the structural behavior of safety systems, alarms, or shutter mechanisms.
- Self-triggering — The act of self-triggering and its result; an automated or mechanical process through which a system, device, weapon, or software program activates autonomously, as a result of detecting an external stimulus or meeting an internal logical condition, without external manual intervention. This structural mechanism is vital for the operation of safety systems, sensors, and cameras.
