Abstract
Methods, systems, and devices that takes advantage of the unique fluid dynamics involved when oscillating flow across a sensor or sensor array. A time-variant source of information about an agent(s) of interest being sensored is established. This source of information is used in machine learning algorithms to speed up the time and accuracy of agent classification and identification.
Claims20
An agent detection method comprising:
- subjecting a sensor to a medium containing an agent of interest via an oscillating flow of the medium, oscillating between a flow into a port in fluid communication with the medium and a flow out of the port;
- establishing a time-variant characteristic associated with the agent of interest from information received from the sensor;
- and
- detecting the agent of interest from evaluation of the time-variant characteristic.

A system comprising:
- a port in fluid communication with a medium containing an agent;
- a station in fluid communication with the port;
- a processor;
- memory in communication with the processor;
- and
- a medium oscillation source configured to subject the station to the medium containing the agent via an oscillating flow of the medium, oscillating between a flow into the port and a flow out of the port;
- wherein the memory stores instructions that, when executed by the processor, is configured to:
- establish a time-variant characteristic associated with the agent from information received from the station;
- and
- detect the agent from evaluation of the time-variant characteristic.

An agent detection method comprising:
- creating, in a medium, a bubble of gas containing an agent of interest;
- subjecting a sensor to an oscillating flow of the gas in the bubble;
- establishing a time-variant characteristic associated with the agent of interest from information received from the sensor;
- and
- detecting the agent of interest from evaluation of the time-variant characteristic;
- wherein the bubble is stable in proximity to the sensor for a time sufficient to complete the step of subjecting the sensor to the oscillating flow.
