Methods and apparatus for generating energy using fall protection devices

This invention describes a safety device, such as a lifeline or lanyard used in fall protection, that generates electricity when a user experiences a fall. The device uses the movement of the rope or lanyard during the fall to power a small generator. This generated power can then be used by an onboard circuit, potentially for sending alerts or other functions. The claims specifically describe mechanisms like a coiled-rope generator or a recoil spring rotating a generator.

Why it matters: Miniaturized, low-power wireless communication modules and more efficient energy storage solutions have emerged since 2017, making it more feasible to reliably power a transmitter from the limited energy harvested during a fall.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateGenerator, mechanical linkage, electrical circuit
