Abstract

An airborne particle collection system includes a monitoring device and a collection media. The monitoring device includes a housing having an air-intake slot, and a motor. The collection media includes an adhesive-coated tape contained within a removable cartridge inserted into the housing. The removable cartridge includes a particle intake zone, proximate to the air-intake slot, and through which the adhesive-coated tape is exposed to capture airborne particles passing through the air-intake slot, and an inspection zone at which the airborne particles captured at the intake zone are transported for optical imaging. The motor moves the airborne particles captured by the adhesive-coated tape from the particle intake zone to the inspection zone.

2. The airborne particle collection system of claim 1 wherein the monitoring device comprises:

a processor; and

a power source, wherein the processor processes information and, based on the processing, directs the motor to move the adhesive-coated tape.

3. The airborne particle collection system of claim 2 wherein the monitoring device comprises:

a network interface controller, coupled to the processor, that receives a plurality of instructions from a remote server over a network, wherein the plurality of instructions comprise:

a first instruction to move the collection media; and

a second instruction to transmit to the remote server an image of the airborne particles that have been captured on the collection media.

4. The airborne particle collection system of claim 1 wherein the monitoring device is powered by an AC power source.

5. The airborne particle collection system of claim 1 comprising:

a light emitting diode (LED) illumination source;

an ultra-violet (UV) LED illumination source; and

an imaging processing module, each of the camera sensor, variable lens, LED illumination source, UV LED illumination source, and imaging processing module being contained within the housing of the monitoring device, and

wherein the LED and UV LED illumination sources illuminate the airborne particles collected onto the collection media for imaging by the camera sensor, the variable lens comprises a lens with an electronically controlled focal length, and the imaging processing module comprises logic to recognize particles of interest imaged by the camera sensor.

6. The airborne particle collection system of claim 1 comprising:

a light emitting diode (LED) illumination source;

9. The airborne particle collection system of claim 1 wherein the monitoring device comprises a processor identifying a collected particle as being of a particular type of pollen by transmitting to a remote server a geographical location of the monitoring device, and obtaining from the remote server context information based on the geographical location of the monitoring device.

10. The airborne particle collection system of claim 9 wherein the context information comprises at least one of pollen types known to be currently blooming at the geographical location, wind patterns at the geographical location, or a listing of pollen types detected by other monitoring devices.

11. The airborne particle collection system of claim 1 comprising a processor identifying a collected particle as being of a particular type of spore by transmitting to a remote server a geographical location of monitoring device, and obtaining from the remote server context information based on the geographical location of the monitoring device.
