Abstract: To improve the power or signal electrical transfer it is described a n electric power/communication system (10). It comprises a first contact surface (22, 24, 32, 34), adapted for being fed by a source (60) to transfer electrical power and/or signal, which is comprised on a surface in sight of a vehicle; and a garment (50) having a second outer contact surface (52, 54), adapted for conducting electric energy and/or receive electrical power and/or signal for a user device (70), which is configured to be able to touch the first contact surface in order to receive electrical power and/or signal.

Abstract: A method is described for inserting or dispersing quartz within a substrate containing polymers polarizable by an electromagnetic field having electrical resistivity, from an insulator to conductor or vice versa, modifiable by said field. The method involves dispersing in the substrate particles having a sandwich structure including two conductive layers and a layer with piezoelectric characteristics in the middle.

Abstract: To mould light, impact cushioning and multi-impact objects a material is disclosed composed in weight of 20-50% of expanded particles and 80-50% of binding component, the particles being in plastic material, of closed shape, hollow and filled with gas.
