A semiconductor device includes a silicon substrate, an SiO film, and a High-K film. In accordance with certain embodiments, carbon nanotube surfaces are functionalized in a non-wrapping fashion by functional conjugated polymers that include functional groups for solubilizing such nanotubes. The blade depth adjustment assembly is mechanically coupled to the handle and configured to permit a user of the utility knife to reposition components of the blade depth adjustment assembly to select one of a plurality of blade depth positions which causes the blade carrier to be repositioned along the handle depending upon which of the blade depth positions is selected. The first panel is attached at peripheral edges to the second panel to define an opening into which an infant torso is received. The electronic device may comprise a partition member to separate the free end of the clip member from the body member, the partition member having contacts corresponding to those of the active pen for enabling charging of the battery module. An electrical component is inside the interior sealed housing, and an intrinsically safe battery is outside of the interior housing but electrically connected to the component inside the interior housing.
