IPC: G06T11/00
Filed: 1997-06-17
Abstract: A method for in-room computer reconstruction of a three-dimensional (3-D) coronary arterial tree from routine biplane angiograms acquired at arbitrary angles and without using calibration objects. The method includes eight major steps: (1) acquiring biplane projection images of the coronary structure, (2) detecting, segmenting and identifying vessel centerlines and constructing a vessel hierarchy representation, (3) calculating bifurcation points and measuring vessel diameters in coronary angiograms if biplane imaging geometry data is not available, (4) determining biplane imaging parameters in terms of a rotation matrix R and a unit translation vector <o>t</o> based on the identified bifurcation points, (5) retrieving imaging parameters if biplane imaging geometry data is already known, (6) establishing the centerline correspondences of the two-dimensional arterial representations, (7) calculating and recovering the 3-D coronary arterial tree based on the calculated biplane imaging parameters, correspondences of vessel centerlines, and vessel diameters, and (8) rendering the reconstructed 3-D coronary tree and estimating an optimal view of the vasculature to minimize vessel overlap and vessel foreshortening.

Title: Solder placement apparatus and method
Inventor: CHERBETTCHIAN AGOP H
IPC: B23K1/00
Filed: 1999-01-25
Abstract: A solder placement device (10) forms a selected length of a solder wire (14) to be used in mounting an optical fiber (20) to a substrate 116 so that the optical fiber (2)) and a laser diode (22) may be optically coupled together. The solder placement device (10) includes casing (16) that contains a plunger (24) arranged for reciprocal movement along an axis in the casing (16). A solder input tube (30) guides solder (14) from a supply spool (12) to a leaf spring retainer (42) inside the casing (16). The leaf spring retainer (42) is mounted to the plunger (24) and arranged to allow unidirectional movement of the solder wire (14) along the axis such that movement of the plunger (24) toward the output end of the apparatus (10) pulls the solder wire (14) along with the plunger (24). When the direction of the plunger (24) reverses, the leaf spring retainer (42) slides along the solder wire (14), and the apparatus (10) resets to pull in another segment of the solder wire (14). A cutting mechanism (86) is actuated by movement of the plunger (24) along the axis to cut off a piece (18) of solder of the selected length. An output tube (87) is mounted to the casing (16) adjacent the cutting mechanism (86). The output tube (87) is arranged to receive the cut off piece (18) of solder wire (14) so that compressed air blows it out through an end 110 of the output tube (87).

IPC: B26D3/28
Filed: 1999-05-18
Abstract: An apparatus for variable length belt splitting includes a stepwise feeder which urges the belt, such as conveyor belt, forward in discrete steps and a reciprocating cutter disposed downstream from the feeder. The feeder preferably includes both a holding clamp and a feed clamp that is connected to, and is moved with respect to, the holding clamp by a feed actuator. The cutter preferably moves parallel to the holding clamp and is moved back and forth by a bi-directional ram. The cutter splits the belt edge to edge at a predetermined depth in length increments corresponding to the feeder's step length to a total length determined by the user. Optionally, the feeder and cutter are connected to a support structure which allows the feeder and cutter to be placed at an angle with respect to the path of the belt through the machine, thereby allowing for diagonal splits to be made with respect to the longitudinal axis of the belt without stewing of the belt. Advantageously, some embodiments of the present invention allow for the belt to be split while maintaining the integrity of the reinforcing layers and the adhesion thereof to the main belt layers. The belt splitter allows for the belt to be split up to any distance selected by the user. A method for splitting belts includes feeding the belt to a cutter in discrete steps having a step length and moving the cutter in a reciprocating manner after each step. The movement of the cutter against the belt splits the belt from one side to the other in length increments corresponding to the step length to an overall split length determined by the user. Optionally, the split is aligned diagonally with respect to the longitudinal axis of the belt. The method preferably splits the belt without damaging any bonds between main layers and reinforcing layers and without damaging the reinforcing layers.

Title: Optical pulse reflectometer
Inventor: WALTER HERBERT
IPC: G01M11/00
Filed: 1997-11-11
Abstract: The object of the invention is to improve the sensitivity of an optical pulse reflectometer (10) without having to increase the transmitting power of the light source (30). For this purpose, instead of a static beam splitter, such as a semi-opaque reflector or 2x2 directional coupler, use is made of an optical switch (40) for the selective connection of the light source (30) to the associated object under test (60) and for the selective connection of the object under test (60) to the associated photodetector (70). In this manner, it is possible to improve the power utilization and thus the sensitivity of conventional optical pulse reflectometers to a very great extent.
