Abstract: The invention relates to novel biocompatible hybrid nanoparticles of very small size, useful in particular for diagnostics and/or therapy. The purpose of the invention is to offer novel nanoparticles which are useful in particular as contrast agents in imaging (e.g. MRD and/or in other diagnostic techniques and/or as therapeutic agents, which give better performance than the known nanoparticles of the same type and which combine both a small size (for example less than 20 nm) and a high loading with metals (e.g. rare earths), in particular so as to have, in imaging (e.g. MRI), strong intensification and a correct response (increased relaxivity) at high frequencies.

Abstract: This invention relates to an electronic system including a radiative electromagnetic emitter for emitting an activation signal including sequentially an energy supply signal followed by an identification signal, the power of the energy supply signal being at least ten times greater than the power of the identification signal, further including an interface connected to an energy supply source; an electric load; a circuit for deactivating a placing of electric load on standby, including: a receiver including a reception interface, a rectifier configured to generate a DC activation voltage on the basis of an activation signal, a switch configured to selectively connect/disconnect to the load from the energy supply, an identification circuit configured to extract an identifier of the activation signal and configured to apply the activation voltage as closure control signal for turning off the switch if a match of the identifier is determined.

Abstract: An automotive vehicle drive unit, comprising a fuel cell whose control input is a setpoint of the electrical power to be delivered by the fuel cell. There is a reversible electrical energy storage system and an electric motor to propel the wheels of a vehicle. An electrical connection element selectively connects the fuel cell and/or the energy storage system to the electric motor. A control circuit stores a model of the consumption of dihydrogen as a function of the power delivered by this fuel cell, in the form of a second-degree polynomial and is configured to compute a coefficient of power distribution ?1 between the fuel cell and the electrical energy storage system pursuant to a defined equation. The control circuit controls the electrical connection element to recharge the energy storage system when the value of the power setpoint Pfc* is greater than the power demanded by the electric motor.

Abstract: A method for dynamically determining the position and orientation of the bone elements of the spine of a person by internal imaging, includes: calculating in a first stage t, the relationships of the vertebrae to one another and relative to the surface of the back; determining equations for a dynamic mechanical model of the spine and for internal stresses on the spine and interactions between the spine and the surface of the back; producing in a second stage t+1, 3D images of the outer surface of the back of the person; and determining for stage t+1, the position and orientation of each of the vertebrae from data acquired from 3D images of the outer surface of the back during stage t+1 and from static position and orientation of data calculated for each of the vertebrae as well as for the shape of the surface of the back during stage t.
