1. A method of tracking a wireless communication device, comprising:
- attaching a first wireless communication device to a second wireless communication device;
after entering a connected state, entering and maintaining a power saving mode as long as a received signal from the first wireless communication device is above a specified threshold, wherein, in the connected state, the second wireless communication device is non-discoverable and non-connectable to other wireless communication devices other than the first wireless communication device;
leaving the connected state and entering a search mode when the signal of from the first wireless communication device falls below the specified threshold, wherein, after leaving the connected state, the second wireless communication device is discoverable and connectable, wherein neither the second wireless communication device nor the first wireless communication device is deactivated if the first wireless communication device and the second wireless communication device are no longer in communication range; and
re-entering the connected state and returning to the power saving mode when the first wireless communication device signal is reacquired.

Abstract
A method, apparatus, and system for tracking and locating Bluetooth enabled devices is described. A network of Bluetooth sniffers can be used to rapidly locate lost devices and their owners. Wearable child devices maintain low power contact with parent devices until such time as a signal limit is reached, at which point the parent devices alarm. An optional network of fixed sniffing devices can be used to coordinate a search for lost child devices once an alert is issued to the system.

15. A system for tracking a wireless communication device, comprising:
-
a first wireless communication device; and a second wireless communication device, wherein the first wireless communication device is attached to the second wireless communication device, wherein, the second wireless communication device, after entering a connected state, enters and maintains a power saving mode as long as a received signal from the first wireless communication device is above a specified threshold, wherein, in the connected state, the second wireless communication device is nondiscoverable and non-connectable to other devices other than the first wireless communication device, wherein the second wireless communication device leaves the connected state when the signal from the first wireless communication device falls below the specified threshold, wherein, after leaving the connected state, the second wireless communication device is discoverable and connectable, wherein neither the second wireless communication device nor the first wireless communication device is deactivated if the first wireless communication device and the second wireless communication device are no longer in communication range, and wherein the second wireless communication device re-enters the connected state and returns to the power saving mode once the first wireless communication device signal is reacquired. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
