Latest Patents

One of his latest patents is a "System and method for monitoring particles in a fluid using ratiometric cytometry." This innovative particle detection system features a detection mechanism with detectors positioned to detect two different ranges of fluorescence produced by particles in a fluid within a flow chamber. The system generates trigger signals whenever fluorescence is detected, thereby improving the monitoring of blue-green algae by utilizing imaging flow cytometry combined with particle analysis. It measures the ratio of each particle's phycocyanin to chlorophyll b using two detectors configured for different fluorescence ranges. Captured images are compared to a library of known images using a support vector machine classifier.

Another significant patent is the "System and method for monitoring birefringent particles in a fluid." This imaging system employs polarization analyzers to provide birefringence images of particles in the fluid passing through the flow chamber. The high-resolution images captured can be compared to known images from a library, enhancing the accuracy and sensitivity of particle monitoring. This system utilizes birefringence imaging combined with particle analysis to detect each particle's characteristic features, including crystalline features.
