Abstract: The invention relates to an immersive device (1), characterised in that it comprises: an attachment element (10) for attaching the device to the head of a user (2), a system for broadcasting video sequences, and an observation system for capturing, broadcasting and/or recording the reactions of the user (2).

Abstract: The invention relates to a system for analyzing a liquid sample, including an analysis device comprising a casing including a through-opening leading into a housing adapted to receive a portion of a collecting device and extending longitudinally from the opening along an axis of insertion of the collecting device. The analysis system further includes a collecting device comprising a main body extending along a longitudinal axis and including a fluid chamber adapted to be inserted in the housing along the insertion axis and a receiving surface intended to receive the liquid sample extending substantially orthogonally relative to the axis of the main body.

Abstract: A liquid-sample analyzer includes a housing that delimits an interior space and a recess adapted to receive a main body of a collection device that collects a liquid sample. When inserted into the recess, the main body extends longitudinally from the opening along a longitudinal axis of the collection device. The detection-and-analysis device is configured to detect and to analyze at least one representative parameter of the liquid sample. The locking-and-releasing retains the collection device in a locking position when the main body has been inserted into the recess. The releasing member exerts an ejection force on the main body toward the opening. The abutment portion contacts a bearing portion of the main body so as to immobilize the collection device while the main body is subjected to the ejection force.

Abstract: An optical chamber for a gas detection device, which includes reflecting device for reflecting radiation issued from a radiation source and for redirecting the radiation toward a radiation detector, the reflecting device including a first series of adjacent mirrors and a second series of adjacent mirrors. The mirrors of the first series and the mirrors of the second series are of the truncated ellipsoid of revolution type. The first series of mirrors and the second series of mirrors are arranged relative to each other so that the radiation emitted by the radiation source is reflected alternatively by a mirror of the second series and by a mirror of the first series and defines an optical path extending from the radiation source to the radiation detector.

Abstract: A chip card for analyzing physicochemical properties of a cutaneous surface includes at least one body sensor which can deliver a signal representing a measurement of a physicochemical property of the cutaneous surface, and a processing unit used to treat signals delivered by the body sensor and an optional environment sensor and to then store signals in a storage unit on the card. An electrical energy source on the card provides electrical power to the body sensor and the processing unit.
