Wireless tag and auxiliary device for use with home monitoring unit for tracking individuals or objects
First Claim
1. A tracking device comprising:
- a position determiner configured to determine a position of the tracking device;
the tracking device having first and second operating modes, the first operating mode being in response to at least the absence of a data communications link with an external wireless node, the second operating mode being in response to at least the presence of communication with an external wireless node;
wherein when in the first operating mode, the tracking device periodically determines its position from the position determiner and maintains a position history of the tracking device;
wherein when in the second operating mode, the tracking device reduces the operations of the position determiner relative to the first operating mode; and
wherein in association with the tracking device transitioning from the first operating mode to the second operating mode, the tracking device wirelessly transmits the position history.

Abstract
A tracking device is provided. A position determiner is configured to determine a position of the tracking device. The tracking device has first and second operating modes, the first operating mode being in response to at least the absence of a data communications link with an external wireless node, the second operating mode being in response to at least the presence of communication with an external wireless node. In the first operating mode, the tracking device periodically determines its position from the position determiner and maintains a position history of the tracking device. In the second operating mode, the tracking device reduces the operations of the position determiner relative to the first operating mode. In association with the tracking device transitioning from the first operating mode to the second operating mode, the tracking device wirelessly transmits the position history.

7. A location tracking system comprising:
-
a local monitoring device; a tracking device having position determining circuitry and first short range wireless circuitry, wherein; the tracking device has first and second operational modes and switches between these operational modes; wherein the tracking device to enters the first or second operational modes based at least in part upon establishing data communications with the local monitoring device; wherein when in the first operating mode and in the absence of data communications with the local monitoring device, the tracking device periodically determines its position from the position determiner and maintains a position history of the tracking device, but does not transmit location related information; wherein when in the second operating mode, the tracking device initially determines its location, becomes wirelessly tethered to the auxiliary device, and subsequently reduces the operations of the position determiner relative to the first operating mode. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for tracking a device, comprising:
-
providing a tracking device, the tracking device comprising a position determiner configured to determine a position of the tracking device; first operating the tracking device in a first operating mode in response to at least the absence of a data communications link with another external wireless node, wherein when in the first operating mode the method further comprises; determining a position of the tracking device from the position determiner; and maintaining a position history of the tracking device; second operating the tracking device in a second operating mode in response to at least the presence of communication with at least one other external wireless node, wherein when in the second operating mode, the method further comprises; reducing operations of the position determiner relative to the first operating mode; and wherein in association with the tracking device transitioning from the first operating mode to the second operating mode, the method further comprises; wirelessly transmitting the position history from the tracking device. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for tracking a device, comprising:
-
providing a local monitoring device; providing a tracking device, the tracking device comprising a position determiner configured to determine a position of the tracking device; first operating the tracking device in a first operating mode in response to at least the absence of a data communications link with the local monitoring device, when in the first operating mode the method further comprises; determining a position of the tracking device from the position determiner; and maintaining a position history of the tracking device; second operating the tracking device in a second operating mode in response to at least the presence of communication with the local monitoring device, wherein when in the second operating mode, the method further comprises; reducing operations of the position determiner relative to the first operating mode; and wherein in association with the tracking device transitioning from the first operating mode to the second operating mode, the method further comprises; wirelessly transmitting the position history from the tracking device to the local monitoring device. - View Dependent Claims (20, 21, 22, 23, 24)
