First Claim
Patent Images
1. An air pollution control device for controlling ambient air pollution in a predetermined space, comprising:
- at least one sensing device for sensing at least one selected polluting gas in said space and for generating a corresponding signal;
a signal conditioning circuit for receiving and amplifying said signal generated by said sensing device;
a comparator circuit for comparing the amplified signal with a predetermined reference signal and providing a corresponding output signal;
a timing circuit for receiving the output signal from said comparator circuit and generating a corresponding timing signal;
pollution diluting means for providing at least one diluting gas for diluting the at least one polluting gas present in said space until desired limits are reached;
decision logic means responding to said timing signal for controlling activation of said pollution diluting means; and
audio/visual means for indicating that the at least one pollutant gas is present and needs to be diluted and for responding to said activation of said pollution dilution means.

Abstract
Process and device are provided for controlling air pollution. The apparatus includes electrochemical, electrothermal and humidity sensors which sense the presence of selected polluting gases and activate an electronic circuitry which controls the release of oxygen, fresh air, or perfumed air and thereby dilutes the concentration of polluting gases within a selected space.
