| 20100265601 | IMAGING MIRROR, METHOD FOR MAKING SAME AND USE THEREOF IN A LASER IMAGING SYSTEM - A mirror for optical imaging includes a reflecting device having a reflective face. The reflecting device incorporates a light-emitting device of which one emitting end is situated in said reflective face in a zone which is not or not very reflective. | 10-21-2010 |
| 20100272320 | Laser Pointing System - A system for pointing a laser beam is provided. The system comprises at least one processing laser source for emitting a processing laser beam toward a target, said processing beam being transmitted through a non-reflective zone of a first mirror, said mirror allowing return to an imaging system receiving an illumination beam reflected by the target, said low reflection coefficient zone of the first mirror inducing a shadow zone toward the imaging system; a second mirror receiving said processing beam and intended to orient it and reflect it toward the target; an illumination source for illuminating said target with the aid of the illumination beam, a first control circuit for controlling the orientation of said pointing system toward the target, a second control circuit for angularly displacing the processing beam by a determined angle, measuring the distance separating the position of a zone of the target from the position of the spot of the processing beam on the basis of an image obtained by the imaging system, then displacing the illumination beam in the opposite sense by an angle corresponding to said measured distance, the angular displacement of the processing beam having an amplitude such that the measurement of the position of the target is not perturbed by the shadow zone. | 10-28-2010 |

| 20100046551 | TRANSMISSION OF A TRIBUTARY IN SYNCHRONOUS MODE AT THE LEVEL OF A LINK OF A DATA NETWORK - The invention relates to a method of transmitting at least one tributary in synchronous mode at the level of a link of a data network, said tributary comprising at least one frame in the SDH or SONET format, said frame comprising at least one payload envelope area and one transport overhead area, said payload envelope area comprising at least one payload and load supervision data related to the payload, said transport overhead area comprising at least transport supervision data related to transport and an area of fixed patterns comprising fixed patterns, said method comprising steps of:—modifying said frame so as to generate a modified frame; transmitting said modified frame, the modification comprising steps in which:—part of said fixed patterns are deleted from said fixed pattern area; the positions of said part of the fixed patterns deleted are recorded; replacement data are inserted at the level of said positions, the method being characterized in that said replacement data comprise the transport supervision data of the frame of said tributary. | 02-25-2010 |
