Abstract
Apparatuses, methods and systems for an event-triggering apparatus are disclosed. One embodiment of the apparatus includes a sensor element operative to sensing a magnetic field, and apparatus control circuitry, wherein the apparatus control circuitry receives a representation of the sensed magnetic field. The apparatus control circuitry is operative to sense a deviation in the sensed magnetic field greater than a predetermined threshold, and trigger an event after sensing the deviation of the sensed magnetic field greater than the predetermined threshold.
