First Claim
1. A cold movement detection system comprising:
- a motion switch module configured to be operably coupled with an axle of a vehicle, the motion switch module comprising at least one motion activated switch, the at least one motion activated switch movable between an open position and a closed position responsive to movement of the axle;
an energy storage module operably coupled to the motion switch module, the energy storage module comprising at least one energy storage element corresponding to the at least one motion activated switch, wherein the at least one energy storage element is configured to discharge a stored charge responsive to the corresponding at least one motion activated switch moving from the open to the closed position;
a resistive module operably coupled to the energy storage module, the resistive module comprising at least one resistive element corresponding to the at least one storage element, the at least one resistive element configured to dissipate energy of the stored charge discharged by the corresponding at least one energy storage module; and
an interface configured to provide information regarding a change in charge state of the at least one energy storage element, wherein the change in charge state corresponds to the movement of the vehicle.

Abstract
A system includes a motion switch module, an energy storage module, a resistive module, and an interface. The motion switch module includes at least one motion activated switch that is movable between an open and a closed position responsive to movement of an axle to which the motion switch module is coupled. The energy storage module includes at least one energy storage element that discharges a stored charge responsive to a motion of the corresponding at least one motion activated switch from the open to the closed position. The resistive module includes least one resistive element that dissipates energy discharged by the corresponding at least one energy storage module. The interface is configured to provide information regarding a change in charge state of the at least one energy storage element, wherein the change in charge state corresponds to a movement of the vehicle.
