Abstract: Embodiments described herein provide systems and methods for generating a three-dimensional virtual track model. This track model may be used, for example, in collision prevention and mitigation systems and methods, such as those described herein, and in other collision prevention and mitigation systems and other mining systems using virtual track models. In some embodiments, the systems and methods described herein provide a simplified modeling process that enables quick, accurate modeling of tracks of a mining machine that can account for custom tracks that vary in size depending on the particular mining machine.

Abstract: A muzzle for use with an animal, the muzzle having a muzzle body, at least one strap circumferentially affixed to the muzzle body and adapted to widen or narrow the muzzle body using a tensioning mechanism and a clip coupled to the muzzle body configured to receive an emergency airway device or an endotracheal tube.
