Abstract

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.

Abstract

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 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

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.
