Method and system for social distance monitoring, alerting and reporting using a combination of ultrasonic transponders and a wireless RF data network

A method for monitoring and reporting personnel social distancing practices using a small personnel monitoring and alerting device incorporating ultrasonic sensors to monitor a complete 360-degree field of view around each wearer in the workplace. The monitoring and alerting devices monitor the distance between personnel wearing the device at preset time intervals using ultrasonic sensors and provides an individual alert (visual, buzzer, and/or vibration) to any wearers that are encroaching within a preset distance of another person wearing the device. Device reports via a RF network to a second device and/or centralized data center on each encroachment and unencroachment event.
