Jeffrey Charles Michalski, Matthew Tant Richardson and Michael Joseph Foley, all of Austin, recently received U.S. Patent 8,205,512 for “Systems and Methods for Collection and Detection of Particulates in the Air.”

 Texas Business Patent of the Day:  Modern days bring the dangers of chemical warfare, biological warfare or dirty bombs.  Three Texans have devised a way of detecting these weapons if ever used.

Jeffrey Charles Michalski, Matthew Tant Richardson and Michael Joseph Foley, all of Austin, recently received U.S. Patent 8,205,512 for “Systems and Methods for Collection and Detection of Particulates in the Air.”

The three men applied for the patent almost four years ago on August 15, 2008.

The patent assignee is Airogistic LLP of Austin.

The invention is in the field, of testing of air for biological, chemical, or nuclear particulates, according to the patent documents.

Walled Cyclones (WC) are mechanical apparatus utilized for the collection of aerosol particles for detection of trace levels of certain biological, explosive, chemical and nuclear materials. The principle of operation is to separate particulates present in the air based on size by taking advantage of the trajectory and flow dynamics of submicron particles as compared to macroscopic particles as the particles enter a rotational vortex in a pipe. The larger particles are acted on by inertial forces that push and separate the larger particulate to the inner wall of the cyclone while the smaller air gas molecules will be exhausted through the center of the pipe, exhausted out via a blower, fan or other air moving device. The inner surface of the cyclone is wetted, coated or consists of a material conducive to capturing particulates. Its surface is conditioned for the purpose of transporting or flushing the particulates into concentrated samples to be evaluated by biological, chemical, explosive or nuclear sensors, detectors, and identification apparatus. 

The invention include systems and methods for collection and identification of particulates in the air. In one embodiment, two different path ways are provided from a single adjustable inlet: one for collection and one for detection. A removable insert positionable within a collection tube enables a user to switch between the collection mode and the detection mode. This embodiment captures both the physical mechanisms of switching the air flow paths as well as sequencing of controls and valves and regulation or changing the air flow rate in the different modes of operation.
