Abstract: A method for determining the occupation state of a parking space, including the steps of: providing a first detection unit equipped with a frequency modulated continuous wave radar; preparing a decision unit and a second detection unit; transmitting via the radar a communication signal modulated on the basis of a first code, alternatively indicating the parking space or a vehicle; receiving the communication signal with the second detection unit; demodulating the first code with the second detection unit; transmitting the first code to the decision unit via the second detection unit; and determining, with the decision unit, the occupation state on the basis of the first code and the second code, alternatively indicating either a vehicle or the parking space.

Abstract: A singulator device for standard postal objects and extended postal objects, configured for receiving at input groups of standard/extended plane rectangular postal objects grouped in packs and supplying at output singulated standard/extended postal objects, i.e., each one is physically separated from the others. The device comprises: a singulator system; a resting surface for the packs of postal objects; and a drawing system that displaces the packs towards the singulator system, designed to withdraw individually the postal objects that form a front end face of the pack. Also provided is a supporting device, configured for providing abut surfaces on opposite end portions of the packs formed by extended postal objects to keep the extended postal objects with planes of lie substantially perpendicular to the direction of advance, thus preventing the extended postal objects from possibly bending towards the adjacent packs formed by standard postal objects.
