Avalanche Victim Marking Device
Individual project for Junior Mechanical Design, Binghamton University.
The Avalanche Victim Marking Device (AVMD) is essential to all mountaineers adventuring in areas of the world that are threatened by avalanches. Three main methods for rescuing an avalanche victim exist, each with its shortcomings. The first solution, a beacon worn by the victim, transmits the victim's location to a rescuer. Many times the snow or location makes it hard to transmit these radio waves. The second solution is a simple shovel used to dig out the avalanche victim. The third is a long probe rescuers jab into the ground in order to locate the victim beneath the snow. In order for the probe to work, the rescuers need to have a good idea of where the victim lies. Even with these three methods of rescue, over fifty percent of victims are killed due to suffocation and later, hypothermia. I sought to find a solution that would mark the victims location and ensure a speedy rescue.
The goal of the AVMD is to mark the location of the avalanche victim and ensure a quick rescue. This device consists of a trigger inflation assembly, a weather balloon and a wire connecting the inflation system to the balloon. A small pin that punctures a helium cartridge triggers the system and the weather balloon inflates with helium gas. It rises above the avalanche and effectively marks the victim's location.

Intensive design project for Junior Mechanical Design, Binghamton University.
The goal of this intensive project was to learn core modeling skills and quickly become proficient in ProEngineering over the course of seven weeks. Beginning with zero knowledge of CAD software, I mastered sketching, part modeling, assemblies, sweeps, lofts and surfacing.
