Abstract
A geo-fencing system () includes a base device () configured to create a virtual fence () around the base devise that bounds a safe zone (). The geo-fencing system further includes a wearable device () initially located within the safe zone. The geo-fencing system further includes a processor configured to execute a dynamic adaptive control algorithm that computes at least one operating parameter for at least one of the base device and the wearable device based on a dynamic and adaptive combination of different signals indicative of distance measurements between the wearable device and the base device computed by the at least one of the base device and the wearable device. The processor conveys the at least one operating parameter to the at least one of the base device and the wearable device, which employs the at least one operating parameter for operation and determination of subsequent distance measurements.
