Abstract: There is provided a sensor for an electroencephalographic (EEC) device for measuring electrical signals generated by the neuronal activity of a subject. The sensor has at least one blade-like contact surface and the contact surface has a curved profile adapted for user comfort and electrical contact.

Abstract: A system and method relating to a brain-computer interface in which visual stimuli are presented in direct association with real world objects such that the intention of the user with respect to objects in the real world can be inferred without the interposition of a screen or other display device.

Abstract: A device for collecting cardiovascular data relating to an individual user, comprising a control unit assembly with an electronic controller and a pneumatic unit, an arm band having an inflatable bladder and configured to surround the left arm of the individual, wherein the pneumatic unit has a pump and a pressure sensor, and is configured to inflate and deflate the inflatable bladder, so that the electronic controller can determine the arterial pressure of the user, the device further comprising an acoustic sensor being coupled to the external wall of the arm band and having a sensitive side such that in use configuration, the sensitive side is adjacent to the chest of the user, whereby at least a cardiovascular timing characteristic can be inferred from signals from the acoustic sensor and the pressure sensor. The device may also comprise a set of contact electrodes to provide additionally ECG functionality.

Abstract: A detection device, for placement under or on a mattress, configured for the movements of a person lying on the mattress, includes a sensing portion having an inflatable chamber intended to be positioned under the individual, an electronic unit arranged at a distance from the sensing portion and having a pressure sensor, intended to be positioned outside of the bedding, a transmitting portion interposed between the sensing portion and the electronic unit, including a channel establishing a fluid connection between the inflatable chamber and the sensor, the channel having a transverse dimension (T) that is much smaller than the width (L1) of the chamber.

Abstract: A sleep assist system to monitor and assist the user's sleep, comprising a bedside device positioned near the user's bed, the bedside device comprising a loudspeaker and a light source and optionally a microphone, a light sensor, a temperature sensor, a control unit, an air quality sensor, a display unit, a user interface. The sleep assist system further comprises a first sensing unit positioned in the user's bed and comprising one or more sensors adapted to sense at least pressure and/or changes in pressure exerted by the user lying in the bed. The system monitors the user's sleep, assesses the user's sleep cycles and the phase of sleep cycle, and provides the user with at least one light and sound program, the light and sound program being based on the assessment of the user's sleep cycles and the phase of sleep cycle.

Abstract: The invention concerns an assembly of a valve body (A) and a seal (11). The valve body (A) includes a gas flow passage (4) and a valve shutter (6) mobile between an open position and a closed position obstructing the movement of the gases in the passage (4). The passage (4) being intended to be connected to a pipe (B) to enable gas to flow between them, the seal (11) being intended to be mounted between the passage (4) and the pipe (B) to provide a gas seal between them. The assembly is characterized in that the seal (11) forms a seat for the valve shutter (6) in the closed position. The seal provides, on the one hand, a seal between the passage and the pipe whether the valve shutter is in the open or the closed position and, on the other hand, a seal for the valve shutter in the closed position.
