Abstract
An improved wearable locator has an ultra-low power RF transceiver, GPS receiver, cellular network RF transceiver, processor, programmable non-volatile memory, LCD display, accelerometer and rechargeable battery. To ensure that the locator is within a perimeter, it can cooperate with a subordinate unit that includes an ultra-low power RF transceiver, processor, power supply, DC charging output, rechargeable battery, visual, audible and tactile enunciators and pushbutton, and can be plugged into an outlet or be unplugged and be mobile. Other wireless units can be used to define a perimeter.
