A solid-state imaging apparatuses IS1 comprises a package P1, a CCD chip 11, chip resistor arrays 21, etc. The driving circuit is coupled to the programmable voltage generator and the back light module for adjusting the brightness level of the light sources inside the back light module according to a plurality of driving voltage signals generated by the programmable voltage generator. A protective mask may be formed over the second masking features. Mobile personal computer is secured to platform insert by impact-resistant cordage. This configuration allows successive closure strips to be nested one into another by inserting the undulation peaks of one closure strip into the hollow nesting volume under corresponding undulation peaks in another closure strip.
