Systems and Methods for Tracking Lifeline Payout and Retraction

This invention describes a safety device, like a retractable safety line for workers at height. It uses sensors to monitor how much of the line is extended or retracted, and if it brakes during a fall. This data, specifically the length of line paid out over time, is recorded and can be used to determine when the device needs maintenance or should be replaced.

Why it matters: The underlying data logging technology was already mature in 2024. The main hurdle remains the rigorous engineering and certification required for integrating sensors into life-critical safety equipment.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateSensors, data storage, output, mechanical integration.
