Title: Apparatus and method for topographical analysis of the retina
Inventor: VERDOONER STEVEN R
IPC: A61B3/12
Filed: 1991-10-24
Abstract: A novel optical subsystem (22, 26, 28, 29) is connected to an analyzing computer (4). The optical subsystem projects a grid of parallel lines (72) onto a patient's retina (52), and a video camera (22) in the optical subsystem captures a first retinal image and transmits it to the computer (4), where the image is digitized for analysis. A second image of the same eye is also captured, with the grid of parallel lines oriented perpendicular to the grid of the first image. The computer (4) stores image data for the patient for a plurality of visits. The computer analyzes the images by forming a skeletonized topographical map of the retinal area of interest. First, a novel one-dimensional line detection algorithm (flowchart, Fig. 7) is used to process the images. The line detection algorithm dilates (104), erodes and restores (106), Fourier transforms (108), bandpass filters (110), thresholds (114), skeletonizes (116), line traverses (118) and interpolates the data for each of the two images. The resulting information is normalized (126) to compensate for the effects of the patient's ocular optics. A topographic line map is constructed (flowchart, Fig 8) using the lines detected in the two images, and the map is divided into sections for analysis. Using selected landmarks, the computer then registers the map with the topographic maps constructed from images acquired on previous patient visits. Volumetric changes in the topography of the retina as compared to the prior topographies for the patient are calculated, and, with other quantities of interest, are displayed in an easily-interpreted report (Fig.  9).

Title: Member for Dispensing a Two-Component Mass from a Tool Separately Discharging the Components
Inventor: KOPP VOLKER
IPC: B01F5/04
Filed: 1993-07-22
Abstract: A member for mixing and dispensing a two-component mass from a tool arranged to separately squeeze-out the two components. The member includes a mixing tube enclosing a coaxial tube section connected to the front end of the tool for conveying one of the components from a tool outlet to the mixing tube. Another tool outlet conveys the other component directly into the mixing tube. The tube section has a one-way valve at an outlet opening into the mixing tube. The one-way valve includes an expandable tubular sheath covering the outlet opening through the tube section. The one-way valve prevents any backflow of the mixed components from the mixing tube into the tube section. Mixed components which harden within the mixing tube form a seal or block. Accordingly, when the tool squeezing out the component is operated with a blocked or sealed mixing tube, no backflow into the tool can occur.
