Abstract

A computer cover (sheath) design concept is shown which, when used with piezoelectric sensors, will enhance the physical security of electronic modules and connectors by minimizing the vulnerability to unauthorized probing. Referring to the figure, a protective sheath 10 is utilized to encapsulate a circuit board populated with integrated circuit modules. The sheath is comprised of a front section 11 and back section 12 which is snap-fastened together around the perimeter to form sheath 10. A long "U"-shaped channel secures the sections together along the overlapping regions at the edges. See points 13 of cross-section A. Another type of snap-fastener 14, shown in cross-section A and in detail A, is located mid-way down front section 11 and back section 12.

Snap Together Cover Assembly and Sensors Utilized to Enhance Computer Security

A computer cover (sheath) design concept is shown which, when used with piezoelectric sensors, will enhance the physical security of electronic modules and connectors by minimizing the vulnerability to unauthorized probing. Referring to the figure, a protective sheath 10 is utilized to encapsulate a circuit board populated with integrated circuit modules. The sheath is comprised of a front section 11 and back section 12 which is snap-fastened together around the perimeter to form sheath 10. A long "U"-shaped channel secures the sections together along the overlapping regions at the edges. See points 13 of cross- section A. Another type of snap-fastener 14, shown in cross-section A and in detail A, is located mid-way down front section 11 and back section 12. This fastener is used to hold the middle regions of the both front and back sections together. A female segment 15 of fastener 14 is located in a post 16 which protrudes through circuit board 17, acting as a standoff and setting the assembly location for the front and back sections. Post 16 is an integral part of back section
12. The male segment 18 of fastener 14 is an integral part of front section 11. Circuit board 17 is secured at the top and bottom in channel 19 which is also an integral part of back section 12. Sheath 10 also provides barriers 20 (see cut- away view) on each side of the backpanel I/O connector (not shown) to...
