A pancreatic cell receiving matrix including a semi-permeable wall and a porous body including a first set of cavities including pancreatic cells, and a second set of cavities free of pancreatic cells. The first set of cavities and the second set of cavities are not fluidically connected to one another. The cavity or cavities left free of cells create paths for the nutrients and gases to diffuse in the matrix, and they form a nutrient and gas reserve area in the matrix. The matrix limits and preferably prevents nutrient and gas depletion of the pancreatic cells. Their mortality is therefore reduced, allowing better insulin delivery.

Through each of its various aspects, the invention proposes a novel droop command and control loop or droop control loop (5) that adapts to the variations in active power available at the inverter (1). This loop may advantageously be implemented on each inverter that, among a plurality of generators connected to the grid, interfaces an intermittent energy source (2), while at the same time guaranteeing: a. correct allocation of active power among the generators, and b. correct signalling, via the frequency at the point of connection of each generator to the grid, of the fact that each generator has reached its active power limits, thereby allowing protective measures to be activated so that each generator of the plurality returns to its active power range.

Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences. Other embodiments are also described.

Abstract
A method for functionalizing a cellulose-based substrate by chemical deposition of at least one thin layer, from gaseous precursors. The method includes the provision of a substrate including at least one sheet having a first face and a second face, of surface roughness greater than or equal to 0.1 μm. The first face has a part superposed to another part belonging to the first face or to the second face. A spacing between said parts is conserved at least locally, so as to enable a diffusion of the gaseous precursors. The method also includes the gaseous chemical deposition of at least one thin layer on the substrate such as provided by diffusion of the gaseous precursors, the gaseous precursors diffusing at least in each spacing.

Abstract
A chaotic physical true random number generator and the generation method associated therewith. The generator includes a resonator 2, an analog-to-digital converter configured to convert an analog signal originating from the resonator into a digital signal 104, a digital processing device configured to generate a sequence of true random numbers on the basis of the digital signal 104, and a device for exciting the resonator configured to excite the resonator with a determined excitation signal to set it in a dynamic multi-stability mode, and modulate the excitation signal, so that the resonant physical component has a chaotic behaviour and that the analog signal is representative of the chaotic behaviour of the resonator. A gain in terms of simplicity of implementation, bulk and/or manufacturing cost is thus achieved for making physical true random number generators in one or more embodiments.

Abstract
A method for determining a region in which the actual concentration is located, in a medium, of a substrate made up of any molecule likely to undergo catalysed oxidation-reduction by a catalyst. The method includes the following steps: taking at least one group of at least two biosensors, each biosensor having a calibration curve of the signal induced by the oxidation-reduction reaction and having identical initial portions of their calibration curves up to a concentration value of the substrate from which the measurement of the signal differ; and when more than one group is present, the biosensors in different groups having different calibration curves without identical initial portions; placing the biosensors in contact with the medium; measuring the signal induced by the oxidation or reduction reaction for each biosensor in the group/groups; comparing all the signal values produced by the biosensors and following the method described in the description.

The present invention relates to a method for charging an electrochemical cell of a rechargeable battery with charging pulse control (PL), the pulses (PL) being driven in voltage control mode in the form of voltage steps (Pt) of variable amplitude. According to the invention, the method consists in calculating the value (Ut+1) of each voltage step (Pt+1) with respect to the value (Ut) of the preceding voltage step (Pt) and according to a progression variable representative of the variation in the internal resistance of the cell (d(R)/dt), for a period ending on the preceding step (Pt), with respect to a predetermined tolerated variation threshold (α), where Var=d(R)/dt−α. The method applies to high-voltage electric battery charging protocols for electromobility or stationary applications, or portable device batteries, for example.
