Abstract

A theft deterrence system is provided for a portable computer. The system includes a portable computer, a theft. deterrence label, a sensor, and circuitry. The theft deterrence label is provided on the portable computer at a visually perceptible location and has indicia that visually alert a reader to deter theft of the computer. The sensor is carried by the portable computer and is configured to enable detection of removal of the label from the portable computer. The circuitry communicates with the sensor and is configured to receive an alert signal from the sensor responsive to removal of the label from the portable computer. The circuitry also disables a functionality component of the computer responsive to the alert signal. A method is also provided.

Claims

1. A theft deterrence system for a portable computer, comprising:

a portable computer;

a theft deterrence label provided on the portable computer at a visually perceptible location and having indicia that visually alert a reader to deter theft of the computer;

a sensor carried by the portable computer and configured to enable detection of removal of the label from the portable computer; and

circuitry communicating with the sensor and configured to receive an alert signal from the sensor responsive to removal of the label from the portable computer and disable a functionality component of the computer responsive to the alert signal.

2. The theft deterrence system of claim 1 wherein the circuitry is provided by processing circuitry of a microprocessor.

3. The theft deterrence system of claim 1 wherein the circuitry is provided by a control system of the computer.

4. The theft deterrence system of claim 1 wherein the circuitry delays disablement of the functionality component of the computer relative to receipt of the alert signal.

5. The theft deterrence system of claim 4 wherein the circuit delays disablement until after occurrence of a number of boot-ups of the computer.

6. The theft deterrence system of claim 4 wherein the circuit delays disablement after a period of time has elapsed since receipt of the alert signal.

7. The theft deterrence system of claim 1 wherein the indicia on the label identify a party with a property interest in the portable computer.

8. The theft deterrence system of claim 1 wherein the indicia on the label identify a misdescriptive mechanism for disabling the portable computer.

9. The theft deterrence system of claim 1 wherein the label comprises a surface that is resistant to bonding with an adhesive or a marking agent.

10. The theft deterrence system of claim 9 wherein the top surface comprises silicon.

11. The theft deterrence system of claim 1 wherein the circuitry is configured to disable boot-up of an operating system of the computer.

12. The theft deterrence system of claim 1 wherein the circuitry is configured to display a text message to a user that the computer is non-functional.

13. The theft deterrence system of claim 12 wherein the circuitry is further configured to display a reward offer for return of the computer to a listed owner of the computer.

14. A mechanism for deterring theft of a portable electronic device, comprising:

a portable electronic device;

a theft deterrence label provided on the device and having indicia that visually alert a reader to deter theft of the device;

detection circuitry configurable to detect removal of the label from the portable electronic device; and

disabling circuitry communicating with the detection circuitry and configurable to disable a functional aspect of the device responsive to the detection circuitry detecting removal of the label.

15. The mechanism of claim 14 wherein the label comprises a text message configured to deter theft of the portable electronic device.

16. The mechanism of claim 15 wherein the text message comprises a warning configured to visually alert a reader to presence of the text message.

17. The mechanism of claim 15 wherein the text message comprises identification information configured to identify an owner of the portable electronic device.

18. The mechanism of claim 15 wherein the portable electronic device is a portable computer.

19. The mechanism of claim 14 wherein the detection circuitry is provided at least in part by a sensor configured to detect presence of the label on the device.

20. The mechanism of claim 19 wherein the sensor is an infrared sensor mounted within the device, and the device further comprises an optical port aligned with the sensor, wherein the label is adhered over the optical port, and the port is configured to guide infrared light waves to the infrared sensor for detection when the label is removed from over the optical port.

21. The mechanism of claim 14 wherein the portable electronic device comprises processing circuitry and the disabling circuitry is provided at least in part by the processing circuitry.

22. The mechanism of claim 14 wherein the label comprises a top surface that inhibits adhesion with adhesives.

23. A method of deterring theft of a portable computer, comprising:

providing a portable computer with a label on a visible outer surface having indicia that visually alert a reader to deter theft of the computer;

detecting removal of the label from the computer; and

responsive to detecting removal, disabling operation of a functioning aspect of the computer.

24. The method of claim 23 wherein the computer includes a sensor configured to detect removal of the label from the computer.

25. The method of claim 23 wherein the computer includes processing circuitry configured to disable a functioning aspect of the computer responsive to detecting removal of the label.

26. The method of claim 23 wherein the indicia comprises at least one of:

a warning, an ownership identification, and an assertion of presence of a remote disabling device.

27. The method of claim 23 further comprising providing an optical port extending from an outer surface of the computer to an optical sensor within the computer and adhering the label over the optical port, and wherein detecting comprises optically detecting light transmission through the optical port responsive to removal of the label from the computer.

28. The method of claim 27 wherein the sensor comprises an infrared sensor configured to detect infrared light waves through the optical port.

29. The method of claim 23 wherein disabling comprises disabling boot-up of an operating system of the computer.

30. The method of claim 23 following disabling, further comprising displaying a message to a user identifying disablement of the function aspect of the computer.

31. The method of claim 30 further comprising displaying a message to a user identifying a reward offer for return of the computer if the computer has been lost or stolen.
