Abstract: The present invention relates to an ultra-wideband signal receiver comprising: at least a first set of sampling cells for sampling the waveform of a received signal; at least a second set of sampling cells for sampling the waveform of the received signal, with a predefined delay ?; and at least one correlator for delivering information depending on the correlation between the waveforms thus sampled.

Abstract: An autonomic network node system for providing at least one virtual router (VR) for providing on demand virtual routing service, the autonomic network node system includes a plurality of autonomic router components (ARCs) comprising at least one autonomic control component (ACC) and at least one autonomic forwarding component (AFC), physical resources comprising a plurality of logical resource partitions (LRPs), at least one database for storing information relating to the plurality of ARCs and LRPs, and a autonomic framework configured for receiving at least one request of on demand virtual routing service, accessing at the at least one database, allocating at least one LRP to perform at least one ARC to be installed in the autonomic network node system, installing the at least one ARC in the autonomic network node system, allocating the installed ARC and, updating the at least one database.

Abstract: The invention relates to an optical imagery device comprising: a light source, an optical medium in which the light coming from the source can be propagated; a detection surface defined by a frontier of the optical medium; an image sensor towards which the light coming from the light source and undergoing reflection onto the detection surface is reflected. The inventive device is characterized in that it is arranged in such a way that from the sensor the source appears to be sufficiently pointed to enable an image to be formed directly on the sensor.
