Abstract: Intercom handset for cellular phones and smartphones provided with a ferritic layer of shielding against the electromagnetic field or E.M.F. emitted by mobile phone devices. The intercom handset can be rapidly inserted onto the cellular phone and used directly connected to the latter by means of an extensible and retractable cable, contained inside its body, or by means of a Bluetooth connection. The intercom handset can also be used separated from the phone, by means of said extensible and retractable cable, contained inside its body, or by means of a wireless connection by means of the built-in Bluetooth module, whose battery is charged by means of an inductive load system that charges the battery of the built-in Bluetooth module, using the radio transmission energy of the cellular phone or smartphone, normally dispersed in the air during the periodic search for the cellular transmission network and during the telephone conversation.

Abstract: Sole for footwear with ventilation induced by the Venturi effect is the present invention. An insole is superimposed that includes a plurality of holes for the passage of air from the sole towards the interior of the shoe. The sole includes at least one inlet opening placed on the lateral frontal surface and at least one outlet opening placed on the back lateral surface. The inlet opening and outlet opening of an airflow channel are each provided respectively with a sliding shutter that reduces the incoming airflow and a sliding shutter that reduces the outgoing airflow and a plurality of air inlet holes made on the insole to make the air enter and exit in correspondence with the foot.

Abstract: A device for the adjustment of the axis of the footrest in motorcycles is described, which device comprises a pair of movable discs (2,2'). The position of the discs is fixed with respect to plate (3) fixed in the frame of the motorcycle, after the position of the footrest is adjusted within the scope of a circumference which has as center the center of the discs and as radius, the eccentricity of the footrest (1) with respect to the same center, as shown in FIG. 1.
