20090214166 | POSITIONING OPTICAL FIBERS - In positioning or aligning ends of optical fibers in relation to each other an offset distance between the fiber ends, the offset distance e.g. being the distance between predetermined reference positions in the fiber ends, is stepwise adjusted using a cascade technique. The method can be executed accurately and fast and be used e.g. in a procedure for core alignment, the predetermined reference positions then being the positions of the cores of the fiber ends such as the positions of the center lines or axes of the cores. Also, the method can be used in a procedure in which the self-focusing effect of optical fibers is used for finding the reference positions, which in this case are the positions of the center lines or axes of the total fiber ends, i.e. center lines or axes of the surfaces of the claddings of the optical fiber ends.

This may extend the range of image analysis allowing e.g. that alignment, in particular core alignment, can be performed without requiring direct information showing the position of sides or edges of the claddings in captured pictures. | 09-22-2011 |

20130066222 | SYSTEMS AND METHODS FOR DETECTING FAR-FIELD OVERSENSING BASED ON SIGNALS SENSED BY THE PROXIMAL ELECTRODE OF A MULTIPOLAR LV LEAD - A device senses cardioelectrical signals using a right atrial (RA) lead, which might include far-field R-waves as well as near-field P-waves. The device concurrently senses events using a proximal electrode of an LV lead, which can sense both P-waves and R-waves as substantially near-field events. Suitable templates are then applied to the signals sensed via the proximal LV electrode to identify the origin of the signals (e.g. atrial vs. ventricular) so as to properly classify the corresponding events sensed in the RA as near-field or far-field events. In this manner, far-field oversensing is conveniently detected. | 03-14-2013 |
