System and method for asset tracking
First Claim
1. A method for asset tracking, comprising:
- transmitting textual data from a user terminal to a remote tracking device of an asset indicating that a theft of said asset is in progress;
respectively compiling coordinate data and acceleration data of said asset from a geomagnetic sensor and an accelerometer associated with said remote tracking device; and
transmitting said coordinate data and said acceleration data from said remote tracking device to said user terminal to provide location information of the asset.

Abstract
A system and method for asset tracking utilizing a wireless device. An asset such as a vehicle can be equipped with a 3-axis geomagnetic sensor and an accelerometer in association with a remote control hardware component capable of responding to SMS (Short Message Service) command transmitted from the wireless device. As soon as the theft of the asset is detected, a “Theft in progress” SMS data can be transmitted from the wireless device to the remote device attached to the asset. The device then queries the geomagnetic sensor and the accelerometer at a pre-defined rate and transmits the X-Y-Z coordinates and acceleration values to the cell phone/computer via SMS at regular intervals. The device can also log the route of vehicle in a non-volatile memory which can be queried utilizing a “Request History” command.

11. A method for asset tracking, comprising:
-
transmitting SMS (Short Message Service) data from a user terminal to a remote tracking device of an asset in response to an event; after the remote tracking device receives the SMS data, sensing coordinate data and acceleration data of said asset with a geomagnetic sensor and an accelerometer associated with said asset; storing said sensed coordinate data and acceleration data over a period of time in a memory of said remote tracking device to define a route of said asset; transmitting said route of said asset stored in said memory of said remote tracking device to said user terminal.

12. A system for asset tracking, comprising:
-
an asset including a tracking device; a user terminal located remote of said tracking device and said asset, wherein said user terminal is configured to transmit textual data to said tracking device in response to a user'"'"'s detection of a theft of said asset in order to activate said tracking device; and wherein said tracking device includes a geomagnetic sensor and an accelerometer, wherein said geomagnetic sensor and said accelerometer are configured to compile coordinate data and acceleration data associated with said asset when activated by said tracking device, wherein said tracking device is configured to transmit said coordinate data and said acceleration data in response to receiving a predefined textual data command from said user terminal. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
