Abstract

A wireless communication device that is attached or included in an electronic object, such as a portable computer, having its own separate communication system. The separate communication system has an antenna for receiving and transmitting wireless communications, and is powered by a power supply included in the object. Since the separate communication system can only communicate when powered, a separate passive wireless communication device is provided for wireless communication that does not require power from the power supply to communicate. The wireless communication device is interfaced with the existing antenna of the separate communication system so that the wireless communication device and separate communication system share a common antenna to reduce cost. The antenna may also be interconnected to a controller associated with the object so that the controller can directly communicate to the wireless communication device.

Claims

1-14. -14. (canceled)

15. A portable computer security system, comprising:

a portable computer, comprising;

a wireless communication device having memory and an antenna for wireless communications, wherein said antenna is adapted to receive communication signals having a defined protocol and a defined operating frequency for processing by said wireless communication device; and

a controller that controls the operation of the laptop computer and that is directly and communicatively coupled to said antenna using at least one connection point;

wherein said controller is adapted to send communication signals emulating said defined protocol at said defined operating frequency over said at least one connection point to said antenna,

wherein said wireless communication device is adapted to receive said communication signals from said controller for processing; and

wherein said controller is adapted to communicate over a network; and

a host computer communicatively connected to said portable computer wherein said portable computer is adapted to communicate a permission token request to said host computer and said host computer is adapted to authorize said permission token request and communicate a permission token in response thereto to said portable computer, wherein said portable computer communicates said permission token to said wireless communication device and said wireless communication device stores said permission token in said memory.

16. The system of claim 15, wherein said wireless communication device is interrogated by an interrogation reader.

17. The system of claim 16, wherein said wireless communication device communicates said permission token to said interrogation reader when said interrogation reader interrogates said wireless communication device.

18. The system of claim 17, wherein said interrogation reader authenticates said permission token by communicating on said network to said host computer to determine if said permission token is authentic.

19. The system of claim 18, wherein said host computer authenticates said permission token by determining if said host computer previously issued said permission token.

20. The system of claim 18, wherein said interrogation reader generates an alarm if said permission token is not authenticated.

21. The system of claim 18, wherein said portable computer is allowed to be removed if said permission token is authentic.

22. The system of claim 18, wherein said interrogation reader communicates with said wireless communication device to erase said permission token from said memory if said permission token is authentic.

23-30. -30. (canceled)

31. A method of authorizing transport of a portable computer, comprising:

requesting a permission token over a network from a host computer;

authorizing said permission token request and sending a permission token in response if said permission token request is authorized;

receiving said permission token over said network by a portable computer;

communicating said permission token to a wireless communication device by sending a communication signal by direct coupling to an antenna coupled to said wireless communication device; and

storing said permission token in a memory coupled to said wireless communication device.

32. The method of claim 31, further comprising interrogating said wireless communication device using an interrogation reader.

33. The method of claim 32, further comprising communicating said permission token to said interrogation reader after said step of interrogating.

34. The method of claim 33, further comprising authenticating said permission token by communicating on said network to said host computer to determine if said permission token is authentic.

35. The method of claim 34, further comprising authenticating said permission token by determining if said host computer previously issued said permission token.

36. The method of claim 34, further comprising generating an alarm if said permission token is not authenticated.

37. The method of claim 34, further comprising communicating with said wireless communication device to erase said permission token from said memory if said permission token is authentic.
