  "textContent": "The purpose of this industrial patent - by Francesco Erba - Via Cardinale Lualdi, 6 - 00165 ROME - ITALY - is to avoid that polluting agents, such as toxic powders and gas, may enter the driver's cabin of motor vehicles and damage their users/passengers. Gas and small solid particles sensors analyze the air that enters the vehicle. When a programmed danger threshold is reached the sensors activate - through appropriate electromechanical devices - the air recycling system and block the inlet of external air. To avoid that too long expositions to polluting agents and consequently too long periods of breathing of the internal air may cause an increase in CO2 percentage and then damages to the passengers, a CO2 absorber is put in the air circuit in order to absorb CO2 produced by passengers' breathing. An O2 sensor is put in the cabin of the motor vehicle to activate the intake of O2 into the vehicle from an external small cylinder in order to maintain the right percentage of O2 in the cabin.",
