Abstract
A fall protection device comprises an energy harvester to generate electrical power in response to movement of an elongate member and a circuit powered by the generated electrical power; an impact indicator connected to an elongate member, a controller connected to the elongate member and/or the impact indicator to generate a message in response to impact, and a transmitter connected to the controller to transmit the message; and/or a sensor connected to an elongate member and a controller connected to the sensor to generate a message in response to movement of the elongate member. The fall protection device could include a generator to generate electrical power, an energy storage capacitor to store the generated electrical power, a controller powered by the energy storage capacitor to generate a message in response to action, and a wireless transmitter powered by the energy storage capacitor to transmit the message.
