Abstract
Systems (100) and methods (300, 400) for controlling access to a restricted area. The methods involve: determining whether a person desires to enter or exit the restricted area based on (1) Received Signal Strength Indicator (“RSSI”) measurement data specifying a power present in a signal received from a Wearable Access Sensor (“WAS”) worn by the person or (2) rate of change data specifying a rate of change of a charging voltage of an energy storage device disposed within the WAS; and causing actuation of a mechanical actuator to enable the person's entrance into or exit from the restricted area when a determination is made that the person desires to enter or exit the restricted area.
