Reusable Breakaway Mounting Device

Breakaway devices are used to mount objects to systems or structures (for example, cars, drones, helmets, buildings) and prevent damage when the objects fall away from the system. Unfortunately, even in ideal scenarios, many of these devices have limitations. Breakaway bolts and shear pins have the complication...
