The locator assembly includes an article of wear and a location sending device embedded in the article of wear. A bio-related electric generator is connected to the location sending device for providing power for the location sending device. A system for locating a person and a locating method are also provided. ## Claims ### Claim 1 A method of locating an individual, comprising the steps of: providing a location sending device including a location determining device, an accelerometer, and a bio-related electric generator, the location sending device configured to determine a transition to a new user motion state from a prior user motion state based at least on data from the accelerometer and data from the location determining device, and configured to send out the new user motion state responsive to the transition; embedding the location sending device, including the location determining device, the accelerometer, and the bio-related electric generator, in an article of clothing comprising at least one of pants, underwear, or a shirt; and receiving by a network-connected computing system location information and the new user motion state from the location sending device via a network. ### Claim 2 (depends on 1) The method according to claim 1, further comprising sending location information from the location sending device when a user is outside of an allowed area and responsive to the transition. ### Claim 3 (depends on 1) The method according to claim 1, further comprising sending location information from the location sending device responsive to the transition and a request from a location requesting device. ### Claim 4 (depends on 1) The method according to claim 1, wherein the article of clothing comprises an elastic band, and the method further comprises embedding the location sending device, including the location determining device, the accelerometer, and the bio-related electric generator, in the elastic band. ### Claim 5 (depends on 1) The method according to claim 1, further comprising sending out location data responsive to the transition. ### Claim 6 (depends on 1) The method according to claim 1, wherein the bio-related electric generator comprises a chemical electric generator. ### Claim 7 (depends on 1) The method according to claim 1, wherein the bio-related electric generator comprises a bio-mechanical electric generator. ### Claim 8 A locator device comprising: a computerized location sending device comprising a location determining device and an accelerometer, the location sending device configured to determine a transition to a new user motion state from a prior user motion state based at least on data from the accelerometer and data from the location determining device, and configured to send out the new user motion state responsive to the transition; at least one battery connected to the location sending device for powering the location sending device; and a chemical electric generator connected to the at least one battery for recharging the at least one battery; wherein the location sending device, the at least one battery, and the chemical electric generator are configured for attachment to an elastic band of an article of clothing. ### Claim 9 (depends on 8) The device according to claim 8, wherein the location sending device is further configured to send out location data responsive to the transition. ### Claim 10 (depends on 8) The device according to claim 8, wherein the location sending device is configured to implement a classifier configured for accessing data from the accelerometer, and the classifier is configured to determine the new user motion state of a user wearing the article of clothing based on at least the data from the accelerometer. ### Claim 11 (depends on 8) The locator device of claim 8, wherein the chemical electric generator is configured to convert body sugar to electricity.
