摘要： A micromachined plate 11, called a torsion plate, selectively pivots upon a substrate responsively to electrical force so as to move an attached micromirror 12 in a same plane; thereby to accurately selectively intercept, and to reflect, a light beam 2 that is moving parallel to the substrate; forming thus an optomechanical switch 1. The electrical force may be electromagnetic 3 in nature or, preferably, electrostatic. In various embodiments the pivoting torsion plate 11 with the micromirror 12 affixed may be (i) biased off the substrate by a three-dimensional structure 14 and/or by a “reshaped” torsion beam 11c, (ii) bent as plate 11d, and operated push OR pull, push AND pull, or push AND push, in a rocking operation, (iii) elevated above the substrate upon a self-assembling “micro-elevator structure” 16, and/or (iv) moved greatly in angular position by action of a “micro-flap” 11f. A new design spring-loaded landing electrode 18, and a torsion microhinge 131-134, further enhance performance. The micromachined, or Micro Electro Mechanical Systems (MEMS), optomechanical switch 1 so formed is both fast and accurate to switch light over large angles up to 180° while being highly resistant to sticking, or “stiction”.

摘要： A method for labeling vessel branches forming first and second vessel systems. A 3D image is segmented to obtain vessel branches. First and second root points are then determined. Starting from the first root point, the vessel branches are traced to derive a tracing path and a break point is determined, that separates the tracing path into two portions. A region of interest in the 3D image is determined with respect to the break point, in which center lines are assigned to the first or second vessel system. A 3D cutting structure is generated based on distances measured from points on the center lines to the 3D cutting structure. Graph representations are constructed for the first and second vessel systems. The vessel branches are labeled with different labels based on the graph representations.

摘要： A method and system is provided for data/process sharing. A trigger response unit is provided to reside on a first system where a first application system is present. The trigger response unit monitors, on the first system, when trigger data from a second application system is presented in the first application system. When the trigger data is presented in the first application system, the trigger response unit decodes the trigger data to obtain a trigger corresponding to a second application system. The obtained trigger is used to launch the second application system on the first system.
