Abstract

The present invention relates to computerized theft and displacement control and observation, dedicated to objects which represent a certain value or importance for its owner and shall thus be observed. In particular, it relates to a wireless, particular Bluetooth-based method and system. A tight, customizable Bluetooth communication involving a positive feedback control signal from the Guardian to the observed device is established (210,220,230) reflecting the usual case. This status is left when the observed device leaves the reception area of the Guardian as the positive feedback signal misses (220,240). Then the observed device sends out (260) standardized “I am stolen” signals which can be received and evaluated fully automatically at multiple locations by respective Theft Monitors. Thus, respective measures can be undertaken to seize the device, e.g., by issuing a selective quiet alarm. (FIG. 2)

Claims

6. The process of claim 1, further comprising communicating the alarm status to a monitoring party.

7. The process of claim 1, wherein an alarm event comprises not receiving an acknowledgement signal from the guardian device within the determined time period.

8. A process for tracking the location of an observed device, the process comprising:

transmitting from the observed device a wireless normal signal indicating a normal operating status;

waiting for a determined time period to receive a wireless acknowledgement signal from a guardian device in response to the lo transmitted normal signal; and

transmitting the wireless acknowledgement signal from the guardian device to the observed device in response to receiving the normal signal from the observed device.

9. A process for tracking the location of an observed device, the process comprising:

transmitting from the observed device a wireless normal signal indicating a normal operating status;

waiting for a determined time period to receive a wireless acknowledgement signal from a guardian device in response to the transmitted normal signal;

transmitting an alarm event signal if the observed device does not receive the acknowledgement signal during the determined time period;

transmitting from the observed device a wireless alarm signal indicating an alarm status in response to an alarm event;

communicating the alarm status to a monitoring party;

transmitting a wireless reset signal from the guardian device to the observed device;

resetting the observed device to the normal operating status in response to receiving the reset signal from the guardian device; and

protecting the observed device against deactivation of the transmission of the alarm signal.

10. An observed device whose location can be tracked, the observed device comprising:

a normal transmission module configured to transmit a wireless normal signal indicating a normal operating status;
