Abstract: A tamper protected printed circuit board assembly including a printed circuit board and a partially enveloping tamper wrap covering the entirety of the top surface of the printed circuit board and a first portion of the bottom surface of the printed circuit board, wherein a second portion of the bottom surface of the printed circuit board is not covered by the tamper wrap is provided. The printed circuit board includes two security trace layers each having two security traces thereon, preferably in a serpentine pattern. The tamper wrap and the security traces together cover and prevent tampering with the electronic circuitry of the printed circuit board.

Abstract: Active contour models and active shape models were developed for the detection of the kinematics landmarks on sequential back surface measurements. The anatomical landmarks correspond with the spinous process, the dimples of the posterior superior iliac spines (PSIS), the margo mediales and the elbow. Back surface curvatures are used as a basis to guide the ACM and ASM's towards interesting landmark features on the back surface. Geometrical bending and torsion costs, and the main modes of variation of the landmark points are added to the models in order to avoid unrealistic curve shapes from a biomechanical point of view. Reconstruction of the underlying skeletal structures is performed using the surface normals as approximations for skeletal rotations (e.g. axial vertebrae rotations, pelvic torsion, etc.) and anatomical formulas to estimate skeletal dimensions.

Abstract: A tamper protected printed circuit board assembly including a printed circuit board and a tamper wrap attached to the printed circuit board. The tamper wrap includes a plurality of side tabs extending from a main body portion and a plurality of corner protection flaps extending from the side tabs. The tamper wrap covers the entirety of a first surface of the printed circuit board and at least a portion of a second surface opposite the first surface of the printed circuit board. Each of the side tabs covers at least a portion of one of the side walls of the printed circuit board and each of the corner flaps is folded around and covers a respective one of the corner edges of the printed circuit board. The printed circuit board may have a plurality of corner sentinels mounted adjacent to the corners of a surface thereof for protecting such corners.

Abstract: A method of attaching a tamper wrap to a printed circuit board using an installation tool that is placed over the main body portion of the tamper wrap. The side tabs of the tamper wrap are folded up against the side walls of the installation tool, and the tamper wrap and the installation tool are inserted into an enclosing case. The installation tool is then removed, the printed circuit board to be wrapped is placed into the enclosing case, and the side tabs are folded and adhered down onto the top surface of the printed circuit board. Also, a printed circuit board assembly having improved heat sinking capabilities including a thermally conductive material located between a printed circuit board and a tamper wrap such that the electronic components are in thermal contact with an enclosing case for enclosing the printed circuit board and the tamper wrap.
