Self-retracting lanyard with fall protection harness tracker

A self-retracting lanyard system comprising:

• a harness connectible to a retractable line of a self-retracting lanyard and wearable by a user of the self-retracting lanyard;
• and
• an electronic device disposable on the harness, the electronic device including:
• an accelerometer;
• a processor or programmable circuit;
• and
• a non-transitory program storage medium on which are stored instructions executable by the processor or programmable circuit to perform operations including receiving a measurement from the accelerometer, comparing the measurement to a threshold, detecting that the user of the self-retracting lanyard has fallen based on a result of the comparing, and instructing a wireless transmitter to transmit a wireless signal in response to the detection that the user has fallen.
