1. A system for locating a person, comprising:a locator assembly comprising:
an article of wear comprising a shoe;
a computerized data sending device comprising a location determining device and an accelerometer embedded in the article of wear, the data sending device configured to determine a transition to a new user motion state from a prior user motion state based on data from the accelerometer and data from the location determining device, and configured to send out the user motion state responsive to the transition;
at least one battery embedded in the shoe connected to the data sending device for powering the data sending device; and
a bio-mechanical electric generator embedded in the shoe connected to the at least one battery for recharging the at least one battery;
a service operator in communication with the data sending device configured to receive the user motion state; and
a network-connectable requesting device in communication with the service operator;
wherein the network-connectable requesting device is configured to contact the service operator, and the service operator is configured to send the user motion state to the requesting device.
