A Electrical Engineering Major's Senior Project

Users of common climbing safety equipment rarely understand exactly the loads and forces they are exerting on the equipment at a given time. All climbing equipment comes with a certified safety rating for the amount of force, in kilonewtons, that particular piece of equipment can take. Unfortunately, calculating dynamic load strain on-the-fly is nearly impossible. There needs to be a reliable, easy way of knowing exactly what load is being placed on a piece of equipment at any given point of time. In addition to safety ratings for a single high impact event(slipping and falling), some climbing equipment, such as a climbing rope, can only handle a finite number of such events. The question is "What is a high impact event?" It's a guessing game at best based on how far you fell, your weight, how your gear was attached to the rock, and the condition of your gear. Safety shouldn't be this guessing game full of gray areas to hand waving. The objective of this project is to create a reliable, high quality, and affordable carabiner that can measure and report its load to the user in real time. If the carabiner approaches its safety limits, the user can immediately be noticed via a smartphone app. The user can also be notified of long-term equipment strain, a count of high impact events, and when it may be time to replace old equipment.
