Simplex personal and asset tracker
First Claim
1. An asset locator system comprising:
- i) a short range hand-held electrical signaling device transmitting an identifier signal, and ii) an asset locator device, the asset locator device further comprising;
a) a wireless receiver capable of receiving an identifier signal transmitted from the hand held signaling device;
b) a wireless transmitter capable of transmitting a message to a space based communication network;
c) a GNSS receiver capable of determining the location of the locator device;
d) an event sensor detecting an event indicating use or imminent use of an asset with which the asset locator is associated; and
e) a controller configured to instruct the asset locator to;
i) attempt to detect the identifier signal from the signaling device if the event sensor indicates a positive condition;
ii) transmit a signal, including an asset location, to the space based network if;
1) the identifier signal is not detected; and
2) location fixes from the positioning system indicate a location change of the asset.

Abstract
An asset locator device including (a) a wireless receiver capable of receiving an identifier signal transmitted from a short range wireless transmitter device; (b) a wireless transmitter capable of transmitting a message to a space based network; (c) a positioning system capable of determining the location of the locator device; (d) a vibration sensor; and (e) a controller. The controller instructs the asset locator to: (i) attempt to detect the identifier signal from the transmitter device if the vibration sensor senses vibration; and (ii) transmit a signal, including an asset location, to the space based network if: (1) the identifier signal is not detected; and (2) location fixes from the positioning system indicate a location change of the asset.

9. A method of detecting an unauthorized location change of an asset equipped with a controller-based security device, the method comprising the steps of:
-
a) sending an interrupt signal to the controller upon detection of a use event; b) enabling a receiver to receive a wireless transmission of an identifier signal associated with the asset; c) if the identifier signal is not received, determining whether the asset has changed location; d) if a change of location is detected, transitioning the controller into an unauthorized use state; and e) after the controller is in the unauthorized use state, transmitting a location and an unauthorized use message to a space based communications network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
