[Thesis]

RF magnetometer for magnetic resonance imaging in a weak magnetic field

Offer N°: SL-DRT-16-0866

Start date: 1 Oct 2016

CEA-LETI's has a long-standing expertise in the field of Helium optically-pumped magnetometers. In the frame of the space project SWARM carried out in collaboration with CNES and ESA, space-qualified atomic magnetometers (TRL8) were designed, realized and characterized. These magnetometers launched in 2013 and dedicated to the measurement of the Earth's magnetic field are based on the paramagnetic resonance of helium 4 atoms (in a gaseous state).



[Thesis]

Adaptive Electronic Interface for Wideband Vibration Energy Harvesting.

Offer N°: SL-DRT-16-0829

Start date: 1 Oct 2016

The main objective of the thesis is to study and develop a smart interface circuit for wideband vibration energy harvesting. An ultra-low power integrated power management circuit will be designed to online adjust the harvester to the surrounding vibration characteristics.



[Thesis]

Embedded speed estimation/prediction filter on an embedded platform fusing multiple range sensors outputs

Offer N°: SL-DRT-16-0821

Start date: 1 Oct 2016

In the context of autonomous vehicles, the environment is perceived thanks to multiple range sensors. The perception aims at localizing the position of potential obstacles. The objective of this thesis is to propose an embedded method for the estimation of the velocity of these obstacles in order to allow their avoidance



[Thesis]

Exploring image sensor design taking advantage on recent advances on compressive sensing and event based representations

Offer N°: SL-DRT-16-0816

Start date: 1 Sep 2016

In the field of smart low-power sensors, emerging breakthrough technologies named compressive sensing and event-based acquisition are of major interest. The first objective of this PhD will be to define proper techniques to take advantage of both methods simultaneously for an imager. Then, based on an identified application, the goal will be to design an image sensor architecture embedding a relevant solution to address pointed out issues.
