Abrégé
The invention relates to a method for achieving ultrasound imaging of an object having two opposite faces, using a pair of multi-element transducers comprising an emit transducer with L elements and a receive transducer with N elements, each placed on the same face or on two opposite faces of the object to be imaged. The invention allows real-time imaging of defects of any shape and orientation in solid structures to be facilitated. To this end, the algorithm described in patent application WO 2020/128344A1 is modified by adding a step of taking account of the distance between the two transducers when writing the spectrum of the image as a function of the spectrum of the received signals. The coordinates of the centre of the receiver, which are then different from that of the transmitter, are added. The expression for the cylindrical (or 3D spherical) wave must then take into account this difference between the positions of the multi-element transmit transducer and the multi-element receive transducer.

To image a new part, the method therefore consists in querying the database in order to select the models of surfaces that best resemble the new surface of the part to be imaged and deducing the point of impact and time of flight values therefrom by simply querying the database or by interpolation from a plurality of values in the database.

The present invention relates to the monitoring of the labor period. The gold standard is currently the monitoring of fetal heart rate (FHR). However, the FHR monitoring is not satisfying since it leads to low false-negative and high false-positive rates. That's why the inventors worked on a more accurate device. Thus, the present invention proposes an intrapartum measurement probe combining several modalities among which ECG and NIRS to accurately and rapidly recognize oxygen delivery and tissue hypoxia in the critically labor situation.

The invention relates to a separator for salts contained in a solution which is brought under supercritical conditions in order to precipitate the salts that it contains within a deformable porous structure. The open porosity of the pores of the structure defines a very large deposition/salt precipitation surface. The solution is injected into the enclosure of the separator by a tube which can reach the inside of the chamber and penetrate into the deformable structure, even in its most deformed state. The porous structure is heated via the side wall of the enclosure at a temperature between 300°C and 1000°C. The inorganic salts contained in the solution are trapped/precipitated in contact with the heated porous structure which is in its deformed state. The flow of the salt-depleted solution is discharged through the dedicated outlet.

The invention relates to a separator for salts contained in a solution which is brought with moving balls by means of a worm, under supercritical conditions. Moving of the heated balls brings them into the hollow cylinder of the worm, where their temperature above the salt precipitation temperature allows the salts to settle on the surface of the balls. Movement of the heated balls in a loop firstly allows the solution for conversion to be heated to a temperature ensuring the precipitation of the salts on the balls and then allows the solution for conversion to be separated into a salt-depleted stream which is discharged from the separator and directed to a conversion reactor, in particular a gasification reactor, and into a stream loaded with dissolved salts to be extracted in the form of a brine discharged by preferably gravity emptying through a grid.

Abrégé
The present invention proposes a method for routing (600) a flow of data in a time-sensitive deterministic network, to route the packets of a flow of data from a transmitting terminal to a receiving terminal, the network comprising switches for the transmission of the packets, the switches being configured to implement predefined transmission planning over repeating time cycles having time slots of fixed length. The routing method of the invention utilises the latency of a path as a metric to calculate (604) the k shortest paths between a transmitting terminal and a receiving terminal then, for each path, determines, for each switch located on this path, a tolerance interval (406) which defines the length of time for which the packets from a stream can wait at the switch before being transferred to the next switch without exceeding the deadline for arrival of each packet from the stream at its destination, in order to reserve free slots (408).

Ultrasound-based wireless communication is proposed as an alternative to electromagnetic communication. The implantable sensor comprises a piezoelectric element and a variable impedance load whose value is a function of a physiological parameter of interest. The load is a solution-gated field-effect transistor (SG-FET), preferably a transistor with a graphene channel. The load is connected to the piezoelectric element for wireless communication with an external device. Experiments show that an ultrasound echo signal can be modulated by the gate voltage of the transistor and that the modulated signal can be transmitted through a propagation medium such a biological tissue.

Abrégé
The invention is a method for determining a depth at which a gamma-emitting radionuclide lies in a solid medium, the latter possibly being concrete or earth. The method is based on a measurement of a spectrum of the gamma radiation emitted by the radionuclide and emanating from a surface bounding the solid medium. Two energy bands are selected in the spectrum. On the basis of spectral values in each energy band, a calibration function allowing the depth to be estimated may be applied. The calibration function is established beforehand based on spectral models.
