A unit for feeding products to a blistering machine includes a delivery group for selectively distributing products to a station, where the products are introduced into respective blisters of a blister band, moving in a forward direction inside the blistering machine. Modules that implement processing logic are allocated per interface and per direction. The invention fully solves the problems of conventional containers, since it achieves a thermostatic preservation of liquids whose duration can be compared to that of thermos flasks and at the same time protects the vessel against any external aggressive agents, such as dust, insects and so forth. The display pattern selected by the logic control unit depends the magnitude and rate of turn. The comparator therefore does not erroneously output an overcurrent detection signal even when noise enters the system. The FRET and charge transfer pathways operate independently, providing for two channels of control for varying luminescence of quantum dots having the same innate properties.
