Abstract
Systems and methods for monitoring attachment of a lifeline assembly to a harness worn by a worker utilize a motion detector module (MDM) for attaching to an anchor tether of a lifeline assembly. The MDM may include a weather-resistant housing containing motion sensing circuitry for detecting significant motions associated with movement of the worker, timing circuitry for monitoring time between significant motions, and a communications transceiver for relaying information regarding significant motions and/or lack thereof to a nearby computing device. The nearby computing device may be a portable device carried or worn by the user. Alternatively, the nearby computing device may be a portable device positioned at a job site and configured to monitor multiple MDMs at the site. The MDM and/or computing device may issue audible alerts upon lack of detection of significant motions. The computing device may communicate noncompliance alerts to a remote computing system of a jobsite manager.
