Deposition apparatus incorporating either a single or multiple filtered cathodic arc source for depositing coatings such as tetrahedral amorphous carbon ; metal oxides; compounds and alloys of such materials onto various types of substrates, such as metals semiconductors, plastics ceramics and glasses. The fluorescent materials may include phosphor materials and non-phosphor materials such as quantum dots. The read information includes a read telephone number stored on the card. The levels of the two analytes may be used to assess insulin sensitivity, to detect both recent hypoglycemia and the cause of high glucose levels, andor to guide therapeutic intervention. An erasing gate is formed over the tapered protrusion of the floating gate.
