An optical device which emits a laser light beam comprises a laser light beam emission source including a source of the laser light beam housed in a package provided with a light beam emission window. CDIS uses an object-oriented and spatial-based approach in which all objects have a set of attributes, while space and areas are defined and tracked. Coated bonded elastomer-metal composites are obtained without an additional application of heat to cure the coating. The inverted sensor module may be used in series with other inverted sensor modules to assess trends such as pressure gradients along a bloodstream. The dielectric is stronger against leakage near at least a portion of the first sourcedrain region than near at least a portion of the channel region.
