First Claim
1. A method for providing assistance to an owner of a vehicle equipped with a theft detection device, the method comprising:
- Receiving a call from the theft detection device at a monitoring center;
Receiving information about triggering event;
Receiving a list of prescribed actions from a primary database server;
Requesting a location processor to determine the location of the theft detection device;
Receiving radio signal information related to the call from a mobile switching center;
Sending radio signals information to a plurality of radio direction finding devices;
Receiving angular information from at least two radio direction finding devicesAnd employing a triangulation method to calculate the location of the theft detection device.

Abstract
The present invention relates to systems and methods to locate and recover objects equipped with tracking devices by determining the location information of the object. The system employs multiple radio direction finding (RDF) devices, which is capable of determining the angle of arrival of a radio signal. The MSC sends a request along with radio information to a location processor, which controls the RDF devices. The system also employs a theft detection device, which is capable of placing a wireless telephone call to a monitoring center. The theft detection device connects to and receives instructions from the monitoring center, which retrieves the instructions from a primary database server. If the primary database server is unavailable, the request for information is sent to a secondary database server.

6. A method for providing assistance to an owner of a vehicle of the type having a selectively activatable air bag, said method comprising the steps of:
-
providing a selectively activatable panic switch;
associating a first action with the sensed activation of said air bag;
associating a second action with the sensed activation of said panic switch;
storing said first and second actions;
sensing the occurrence of one of said first and second actions;
locating said vehicle only by the use of a cellular telephone system upon the sensed occurrence of one of said first and second actions;
associating a first reaction to said first action;
associating a second reaction to said second action;after locating said vehicle, determining the identity of said sensed action; and performing the associated reaction of said sensed action. - View Dependent Claims (7)
