Precision Positioning of Microrobots for Multi-Object Spectrographs

How does one study the evolution of the Milky Way, or the expansion of the Universe, or explore the mysteries of Dark energy? To investigate these complex topics, astronomers require data, and a great deal of it, in the form of the spectra of stars, galaxi ...

DETERMINING POSITIONS OF TRANSDUCERS FOR RECEIVING AND/OR TRANSMITTING WAVE SIGNALS

Paul Hurley, Matthieu Martin Jean-André Simeoni, Nezihe Merve Gürel

The invention is notably directed to a method for determining positions {pi}i=1,..., N of transducers {Ai}i=1,..., N of an apparatus. The transducers are assumed to be configured for receiving wave signals from and/or transmitting wave signals to one or mo ...

First spatial alignment of the LHCb VELO and analysis of beam absorber collision data

A first alignment of the LHCb Vertex Locator has been obtained from beam induced tracks at the LHC. A 450 GeV/c protons were collided on a beam absorber during the LHC synchronisation tests of the anti-clockwise beam in August and September 2008. The resul ...

Organ Surface Markerless Tracking

Coralie Reissner

Today’s surgical navigation systems are difficult to use for deformable organs. State of the art technology struggles to continuously update and display preoperative information such that it corresponds to the actual position of the organ. An update method ...

A Galileo E1b,c RF front-end for Search-and-Rescue applications

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti

The current Search-and-Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the 121.5MHz/(up to ...

Evolutionary Active Vision Toward Three Dimensional Landmark-Navigation

Dario Floreano, Mototaka Suzuki

Active vision may be useful to perform landmark-based navigation where landmark relationship requires active scanning of the environment. In this article we explore this hypothesis by evolving the neural system controlling vision and behavior of a mobile r ...

A flexible Galileo E1 Receiver Platform for the Validation of Low Power and Rapid Acquisition Schemes

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti, Giuseppe Zamuner

With the inclusion of 406 MHz transponders on the Galileo satellites and the new search and rescue (SAR) return link message (RLM) on the open service E1B signal, the availability of distress beacons equipped with a Galileo or combined GPS/Galileo receiver ...
