Abstract

The present invention relates to a portable computer security device that includes a protective mounting structure for an LCD. The portable computer security device includes a cover and a base and further includes an integrated circuit and a LCD assembly that are each positioned between the cover and the base. The LCD assembly is electrically connected to the integrated circuit. The integrated circuit generates random numbers for display on the LCD assembly such that the random numbers may be used to provide access to a computer system. In addition, the LCD assembly is aligned with an opening in the cover to permit observation of the LCD assembly through the opening in the cover. The portable computer security device further includes a damping member. The damping member is positioned between the LCD assembly and the cover to reduce shock and vibration forces that are generated on the LCD assembly.

Claims

1. A portable computer security device comprising:

a cover;

a base;

an integrated circuit within the base;

a LCD assembly positioned between the cover and the base such that the LCD assembly is aligned with an opening in the cover to permit observation of the LCD assembly through the opening in the cover, the LCD assembly being electrically connected to the integrated circuit, the integrated circuit generating random numbers for display on the LCD such that the random numbers are used to provide access to a computer system; and

a damping member positioned between the LCD assembly and the cover to reduce shock and vibration forces that are generated on the LCD assembly.

2. The portable computer security device of claim 1 wherein the damping member includes an opening such that the LCD assembly is visible through the opening in the damping member.

3. The portable computer security device of claim 1 wherein the damping member has a rectangular outer shape.

4. The portable computer security device of claim 1 wherein the damping member is formed of a silicone gel.

5. The portable computer security device of claim 1 wherein the cover includes a recess such that the damping member is positioned within the recess in the cover.

6. The portable computer security device of claim 1 wherein the damping member touches the cover and touches the LCD assembly.

7. The portable computer security device of claim 1 wherein the integrated circuit is part of a circuit board.

8. The portable computer security device of claim 7 wherein the LCD assembly is electrically connected to the circuit board using a flexible conductor.

9. The portable computer security device of claim 8 wherein the flexible conductor is a zebra strip.

10. The portable computer security device of claim 7 wherein the damping member is a first damping member and the portable computer security device further comprises a second damping member, the second damping member being between the LCD assembly and the circuit board to reduce shock and vibration forces that are generated on the LCD assembly.

11. The portable computer security device of claim 10 wherein the second damping member touches the circuit board and touches the LCD assembly.

12. The portable computer security device of claim 10 wherein the second damping member has a linear shape.

13. The portable computer security device of claim 1 wherein the LCD assembly includes a glass LCD.

14. The portable computer security device of claim 13 wherein the glass LCD has a rectangular shape.
