1. An apparatus comprising:
an explosive material;
a battery;
an electrical circuit extending from the explosive material to the battery, the electrical circuit including a switch having a connected state in which the battery and the explosive material are electrically connected through the switch and a disconnected state in which the battery and the explosive material are electrically disconnected;
a processor electrically coupled to the switch, the processor configured to generate an output signal that transitions the switch from the disconnected state to the connected state to activate the explosive material in response to an input signal from one or more sensors;
a cylinder having a moveable internal wall that defines first and second chambers, the explosive material disposed in the first chamber; and
a rod or wire having a first end attached to the moveable internal wall and a second end attached to a ski,
wherein:
the apparatus is configured to be mounted on or in a ski, a ski boot, and/or a ski binding, and
activation of the explosive material generates a gas that increases a pressure in the first chamber,
an increase in the pressure in the first chamber causes the moveable internal wall to move towards the second chamber, thereby causing the first end of the rod or wire to move towards the second chamber,
the rod or wire passes over a pulley that translates a movement of the first end of the wire in a first direction to a movement of the second end of the wire in a second direction that is opposite to the first direction, and
the movement of the second end of the rod or wire causes the ski boot to lift out of a ski binding.
