A semiconductor package structure comprises a lead frame, at least one chip, a molding compound and an anti-conduction film. The recognition platform causes, at least in part, a generation of a request to determine recognition information for one or more media items associated with a device, one or more segments of the one or more media items, or a combination thereof. This synchronization process builds a baseline data structure of target data files. Alternatively, the determined ratio COCIOC or COCTOC for said person, is compared to the mean ratio COCIOC or COCTOC, determined from measurements in similar body fluid samples of the population of the same age and sex. A recessed channel is in at least one of the slider pad or the suspension pad.
