Abstract: The present invention relates to a device for the detection and measurement of the physical-chemical features of materials in the form of sheets comprising a microwave sensor coupled to a passive reflector on the other side of the material to be measured. The invention further comprises calculation methods and algorithms for processing output data, adapted to make the measurement immune from the typical environmental factors of industrial environments.

Abstract: An apparatus for controlling safety and preventing accidents at the workplace comprising: a plurality of RF transceivers (11), each associated with either a garment or an accessory or an instrument to be used by an operator when engaged in an area of concern, a plurality of illuminating actuators (12, 14, 16) and receivers (13, 15, 17), each of which associated with either the apparatuses or the structures or parts thereof arranged in said area of concern, said RF transceivers (11) being configured to form a network of PAN or BAN type, and comprising at least one RF transceiver (10) configured as a MASTER of said PAN or BAN network, characterized in that at least one of said RF transceivers comprises a dual-frequency controlled RFID transmitter device (10).

Abstract: The object of the present invention is a device for the detection of concealed objects which exploits a transceiving system of the microwave type.

Abstract: The object of the present invention relates to a dual-band transponder-based apparatus for space-time identification and location that carries out the data exchange between a query device and one or more responders, being located within an appropriate distance range from said query device.

Abstract: The object of the present invention is a device for the detection of concealed objects which exploits a transceiving system of the microwave type.

Abstract: A fuel purifier for separating and removing polluting water from hydrocarbon fuels, comprising a decantation vessel having at its upper end a normally open inlet and an outlet opening and at its bottom end a second normally closed outlet opening, a source of light and a photocell arranged in opposite positions in a tubular central wall portion of the decantation vessel, and a float vertically movably mounted within the decantation vessel to normally close the path of light from the source of light to the photocell, but adapted to move under the action of the water accumulating at the bottom of the decantation vessel to an upper position in which the photocell receives light from the source of light to open the second outlet opening to drain the water.
