20090166297 | Blood Processing Apparatus with Controlled Cell Capture Chamber Trigger - A blood cell collection system having means for detecting when a cell separation chamber has filled with white blood cells, and flushing the cells out of the cell separation chamber into a collect bag. A red-green sensor senses the optical characteristics of fluid leaving the cell separation chamber. A baseline value is calculated. The device calculates a ratio of the intensities of red light and green light and a peak-to-peak ratio of intensities. If either ratio exceeds thresholds computed from the baseline, the device flushes the cells into the collect bag. A camera detects white cells passing into the cell separation chamber and the device calculates the number of cells being collected. If the calculated number of collected cells exceeds a certain limit, the cell separation chamber is flushed. If the device is unable to establish a baseline, the donation can proceed, relying solely on the calculated number of collected cells. | 07-02-2009 |

20130072367 | Blood Processing Apparatus with Robust Automated Process Control - A centrifuge for separating blood having a camera observing fluid flow, and a controller controlling the flow. The location of an interface is detected by image processing steps, which may comprise the steps of “spoiling” the image, “diffusing” the image, “edge detection”, “edge linking”, “region-based confirmation”, and “interface calculation”. “Spoiling” reduces the number of pixels to be examined preferentially on orthogonal axis oriented with respect to the expected location of the interface or phase boundary. “Diffusing” smoothes out small oscillations in the interface boundary, making to the location of the interface more distinct. “Edge detection” computes the rate of change in pixel intensity. “Edge linking” connects adjacent maxima. “Region-based confirmation” creates a pseudo image of the regions that qualify as distinct. “Final edge calculation” uses the points where the shade changes in the pseudo image, averages the radial displacement of these points for the interface position. | 03-21-2013 |
