System and method for detection and prevention of influx of airborne contaminants
First Claim
1. A system for detection of airborne contaminants and prevention of influx of the contaminants into a vehicle cabin, the vehicle cabin being provided with a ventilation system including at least one valve, the system comprising:
- a first sensor array adapted to sample exterior air prior to influx of the exterior air into the cabin, wherein the first sensor array is installed in an air inlet duct of the ventilation system and is capable of generating data uniquely corresponding to each contaminant;
a microprocessor operably coupled to the first sensor array;
a computer memory operably coupled to the microprocessor and having data stored therein corresponding to one or more predetermined contaminants;
input means wherein a user can cause data corresponding to a contaminant selected by the user to be stored in the computer memory; and
an actuator operably coupled to the microprocessor,wherein;
the first sensor array generates data for comparison with data stored in the computer memory to identify contaminants in the exterior air; and
the actuator is operative to control a position of the at least one valve to prevent influx of the exterior air into the cabin upon identification of a contaminant having data stored in the computer memory; and
the input means includes a portable sensor array capable of being operably connected to and disconnected from the system, wherein the portable sensor array is a self-contained unit operative to;
generate data to identify airborne contaminants;
store the data; and
, with the portable sensor array operably connected to the system, download the data to the computer memory.

Abstract
An apparatus and method for detection of airborne contaminants and prevention of influx of the contaminants into an enclosed space, such as a vehicle cabin. A first sensor array samples exterior air prior to influx of the exterior air into the enclosed space. The first sensor array generates data uniquely corresponding to each contaminant. Data corresponding to predetermined contaminants is stored in computer memory. A user may also cause data corresponding to a contaminant selected by the user to be stored in the computer memory. Upon identification of a contaminant, an actuator is operative to control a position of a valve to prevent influx of the exterior air into the enclosed space.
