A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. A heater element is disposed against an input end of the SMA tubes and generates heat when electrical current is applied thereto. The metadata for the music files is checked for an artist name in a \u201clast name, first name\u201d format, for a mixed up track title and artist name, and for artists that appear in multiple genres. This configuration allows a formation of the map for separation with respect to each imaging condition, and high degree of accuracy in separating composition can be achieved. A fine ADC receives the two voltage subranges and the voltage input. An isolating via can extend through the conductive carrier substrate to the dielectric material and surround the exposed portion of the first contact to define first and second terminals electrically accessible from the first side.
