Abstract

Examples herein relate to intrusion switch. In particular, implementations herein relate to a computer system including a housing enclosing at least one electronic component therein. The housing includes a base and a removable cover. The cover is movable between engaged and disengaged positions relative to the base and extends over at least a portion of the base and is secured to the base in the engaged position. The cover is removable from the base when the cover is in the disengaged position. The computer system further includes an intrusion switch configured to detect access to an interior of the computer system. A portion of the cover extends through a slot in one of the sidewalls of the base and contacts the intrusion switch when the cover is in the engaged position. Contact between the cover and the intrusion switch is released when the cover is in the disengaged position such that the intrusion switch can detect when the cover is moved to the disengaged position.

First claim

The invention claimed is:

1. A computer system comprising:
a housing enclosing at least one electronic component therein, the housing including a base and a removable cover, the base having opposing sidewalls, the cover movable between engaged and disengaged positions relative to the base, the cover extending over at least a portion of the base and being secured to the base when the cover is in the engaged position, and the cover being removable from the base when the cover is in the disengaged position; and
an intrusion switch configured to detect access to an interior of the computer system, the intrusion switch disposed within an interior of the base, wherein a portion of the cover extends through a slot in one of the sidewalls of the base and contacts the intrusion switch when the cover is in the engaged position and wherein contact between the portion of the cover and the intrusion switch is released when the cover is in the disengaged position such that the intrusion switch detects access to the interior of the computer system when the cover is moved from the engaged position to the disengaged position.

2. The computer system of claim 1 , wherein the intrusion switch is coupled to one of the sidewalls of the base.

3. The computer system of claim 1 , wherein the portion of the cover extending through the slot in contact with the instruction switch when the cover is in the engaged position is a protrusion extending medially towards interior of the base.

4. The computer system of claim 1 , wherein the intrusion switch detects access to the interior of the computer system in response to the cover being moved from the engaged position to the disengaged position prior to the cover being removed.

5. The computer system of claim 1 , wherein the at least one sidewall of the base including the slot includes a lip portion extending over an upper portion of the intrusion switch.

6. The computer system of claim 1 , wherein the cover is slidable between the engaged and disengaged positions.

7. The computer system of claim 6 , wherein the cover is slidable towards a front end of the base to be moved to the engaged position and towards a rear end of the base to be moved to the disengaged position from the engaged position.

8. The computer system of claim 1 , wherein the intrusion switch indicates access to the interior of the computer system when contact between the protrusion of the cover and the intrusion switch is released.

9. The computer system of claim 1 , wherein the cover is configured to be lifted upward away from the base to be removed after being moved to the disengaged position.

10. The computer system of claim 1 , wherein the intrusion switch is disposed entirely within the base when the cover is in either engaged or disengaged positions.

11. A computer system comprising:
a housing including a base and a removable cover, the base having opposing sidewalls, the cover movable between engaged and disengaged positions relative to the base and being secured to the base in the engaged position; and
an intrusion detection circuit configured to detect when the cover has been moved from the engaged position to the disengaged position, the intrusion detection circuit comprising an intrusion switch disposed within an interior of the base movable between first and second positions, wherein a portion of the cover extends through a slot of one of the sidewalls of the base and contacts the intrusion switch when the cover is in the engaged position to move the intrusion switch to the first position and wherein contact between the portion of the cover and the intrusion switch is released when the cover is in the disengaged position to move the intrusion switch to the second position, and wherein the intrusion detection circuit in response to the intrusion switch being moved from the first position to the second position detects the cover has been moved from the engaged position to the disengaged position prior to the cover being removable from the base.

12. The computer system of claim 11 , wherein the intrusion switch is coupled to one of the sidewalls of the base.

13. The computer system of claim 11 , wherein the cover is slidable between the engaged and disengaged positions.

14. The computer system of claim 11 , wherein when the intrusion switch is in the first position the intrusion detection circuit is a closed circuit and when the intrusion switch is in the second position the intrusion detection circuit is an open circuit.

15. The computer system of claim 11 , wherein when the intrusion switch is in the first position the intrusion detection circuit is an open circuit and when the intrusion switch is in the second position the intrusion detection circuit is a closed circuit.

16. The computer system of claim 11 , wherein the intrusion detection circuit after detecting the cover has been moved from the engaged position to the disengaged position is configured to indicate to a user the cover has been moved from the engaged position to the disengaged position when the computer system is powered on.

17. The computer system of claim 11 , wherein the intrusion detection circuit is configured to identify that the cover has been moved from the engaged position to the disengaged position by activating an alert.

18. The computer system of claim 17 , wherein the alert comprises at least one of an audible signal, a visual signal, or a haptic signal.

19. The computer system of claim 11 , wherein the intrusion detection circuit is configured to transmit a signal to a remote monitoring system to indicate the cover has been moved from the engaged position to the disengaged position.
