    摘要: An endoscopic method involves an advancement of an endoscope (20) as controlled by an endoscopic robot (31) to a target location within an anatomical region of a body, and a generation of a plurality of monocular endoscopic images (80) of the anatomical region as the endoscope (20) is advanced to the target location by the endoscopic robot (31). For avoiding or detecting a collision of the endoscope (20) with and object within monocular endoscopic images (80) (e.g., a ligament within monocular endoscopic images of a knee), the method further involves a generation of distance measurements of the endoscope (20) from the object as the endoscope (20) is advanced to the target location by the endoscopic robot (31), and a reconstruction of a three-dimensional image of a surface of the object within the monocular endoscopic images (80) as a function of the distance measurements (81).

    摘要: The invention relates to position determining system (201) for determining a position of an object (2). A first position detection unit (205) detects a first position of the object (2) based on radiation transferred between the object (2) and transfer positions being known relative to a reference position by a sending and receiving unit (203, 214, 216, 217). A second position detection unit (35) detects a second position based on an acceleration of the object (2) and the determined first position, wherein an output unit (12) outputs at least one of the first position and the second position. If the transfer of radiation is interrupted, the second position can be output by the output unit. Moreover, the first position can be used as an initial value for determining the second position or to update the second position. This improves the quality of determining the position of the object.

    摘要: A thin-film coupler with a carrier substrate (1) and two strip lines disposed thereon, of which one represents the main coupler loop (2) and one the auxiliary coupler loop (3). The use of inexpensive carrier substrate materials and a compact construction are made possible through an integration of a strip line, a coil, or an LC combination into the auxiliary coupler loop (3). The integration of these components (4) achieves a phase shift in the frequency of the signal coupled out so that a broadband coupler is obtained which exhibits an identical coupling at at least two frequencies.
