20100134517 | METHOD FOR AUTOMATIC BOUNDARY SEGMENTATION OF OBJECT IN 2D AND/OR 3D IMAGE - Segmenting the prostate boundary is essential in determining the dose plan needed for a successful bracytherapy procedure—an effective and commonly used treatment for prostate cancer. However, manual segmentation is time consuming and can introduce inter and intra-operator variability. This present invention describes an algorithm for segmenting the prostate from two dimensional ultrasound (2D US) images, which can be full-automatic, with some assumptions of image acquisition. Segmentation begins with the user assuming the center of the prostate to be at the center of the image for the fully-automatic version. The image is then filtered to identify prostate edge candidates. The next step removes most of the false edges and keeps as many true edges as possible. Then, domain knowledge is used to remove any prostate boundary candidates that are probably false edge pixels. The image is then scanned along radial lines and only the first-detected boundary candidates are kept the final step includes the removal of some remaining false edge pixels by fitting a polynomial to the image points and removing the point with the maximum distance from the fit. The resulting candidate edges form an initial model that is then deformed using the Discrete Dynamic Contour (DDC) model to obtain a closed contour of the prostate boundary. | 06-03-2010 |

20100212956 | SAFETY PLUG FOR SEALING BUS BAR END CONNECTIONS - A sealed covering for exposed portions of electrical wires at an end of a protective tube, which houses a bus bar and has a cover shield, includes a plug. The plug includes two opposed hinged shells forming, when closed, a cavity for receiving a cable and a flange for engaging the cover shield. A method for enclosing at least one electrical splice between at least one electrical wire and at least one bus bar employs the sealed covering. | 08-26-2010 |

20100107591 | TURBOMACHINE FLAMEOUT CONFIRMATION - Methods and apparatus are provided for detecting a flameout of an operating turbomachine that is configured to receive a controlled flow of bleed air from a bleed air source and a controlled flow of fuel from a fuel source. A value of an operational parameter within the turbomachine is detected and a determination is made as to whether it has varied by a predetermined amount. If the operational parameter has varied by the predetermined amount, a flameout confirmation test is triggered. The flameout confirmation test includes holding the controlled flow of bleed air constant, commanding an increase in turbomachine speed, and confirming that a flameout has occurred by detecting that the controlled fuel flow to the turbomachine is at a maximum fuel flow limit and that actual turbomachine speed differs from the commanded turbomachine speed by a predetermined speed error. | 05-06-2010 |
