Abstract

A system for extracting carbon dioxide from a mixture of gases that include at least carbon dioxide, wherein a reservoir is provided that contains a material capable of adsorbing the carbon dioxide, the reservoir having an inlet for the mixture and an outlet for a mixture that is at least partially purified of carbon dioxide, where the system also includes at least one element for heating the reservoir, at least one electronic control circuit that causes a heating of the reservoir when at least one condition is fulfilled, so as to give rise to the desorption of the carbon dioxide adsorbed on the material contained in the reservoir.

Abstract

The invention relates to a system for extracting carbon dioxide from a mixture of gases comprising at least carbon dioxide, comprising at least one reservoir (10) containing a material (20) capable of adsorbing the carbon dioxide, each reservoir comprising an inlet (13) for said mixture and an outlet (14) for a mixture that is at least partially purified of carbon dioxide, which may moreover comprise: at least one means (40) for heating said reservoir, at least one electronic control circuit (50), provided in order to give rise to the heating of at least one reservoir when at least one condition is fulfilled, so as to give rise to the desorption of the carbon dioxide adsorbed on the material contained in the respective reservoir.

Abstract

The invention relates to a device (50) comprising at least one electronic circuit (52) and a battery (53) provided for powering said circuit, wherein the circuit and the battery are included in a block of hydrophobic material, for example a block of resin (51). The battery is, for example, an inductively charged battery and the device can comprise optical sockets (56a, 56b, 56c) for fibre-optic cables, so as to avoid all contact of metal parts with water. Such a device is especially suitable for a buoyancy compensator vest, for use as a "stabiliser during immersion" and as a "closed-circuit rebreather".

Abstract

The invention relates to a device for monitoring the production of a photovoltaic facility (I), characterised by including: a photosensitive cell (1), a translucent means for protecting the cell comprising a first area (3a) arranged across the optical axis (Χ-Χ') of the cell (1) and a second protected area, a means for substituting the first area for a portion of the second area. The protection means can comprise a film wound onto a supply reel (2a) which unwinds before the entry point (1a) of the cell, such as to protect the first area (3a) from soiling.
