Abstract
An aerosol deflection system having a concentration zone expelling an air stream through a first detection zone, a second detection zone, and a deflection zone. The first detection zone activates the second detection zone based upon detection of a suspect aerosol of a pre-selected size. The second detection zone activates the deflection zone when the suspect aerosol of the pre-selected size has a predetermined light-induced-fluorescence signature. The deflection zone directs a pressure pulse at the suspect aerosol having the predetermined light-induced-fluorescence signature to deflect the suspect aerosol from the air stream.
Claims20
An aerosol deflection system comprising:
- a concentration zone configured to expel an air stream through a first detection zone, a second detection zone, and a deflection zone;
- said first detection zone configured to activate said second detection zone based upon detection of a suspect aerosol of a pre-selected size;
- said second detection zone configured to activate said deflection zone when said suspect aerosol of said pre-selected size has a predetermined signature;
- and
- said deflection zone configured to direct a pressure pulse at said suspect aerosol having said predetermined signature to deflect the suspect aerosol from said air stream.
A method for deflecting aerosols from ambient air, comprising:
- generating a defined stream of the ambient air;
- causing a suspected aerosol suspended in said defined stream to emit a signature when said suspect aerosol has a predetermined size;
- detecting said signature from said suspected aerosol;
- and
- removing said suspected aerosol from said defined stream via a pressure pulse when said signature is a predetermined signature.
