Abstract: An implantable device includes a lead, for example for neurostimulation of the vagus nerve. The lead includes a series of stimulation electrodes and a series of external electrodes for bioimpedance measurements on blood flow located in the same region, for example on the carotid artery. The device further includes means for separating into frequency bands the measured bioimpedance signal, the bands selected to reflect different respective activities such as vasomotor activity, hemodynamic activity, respiration, and cardiac rhythm activity.

Abstract: A method of automatic positioning a seat in an apparatus comprising two cameras located on either side of the seat, each one in a position able to acquire images of a face of a user seated on the seat. The seat comprises at least one motor, each motor acting on a position of the seat along a predefined axis. The method comprises: for each camera: obtaining a position of a predefined image zone in which at least one eye of a user of the apparatus should be located; acquiring an image of a user seated on the seat; detecting at least one eye of the seated user in the image acquired; and obtaining a relative position between each eye detected and the predefined zone. By using each relative position obtained, at least one motor is actuated until each predefined zone contains at least one eye of the seated user.

Abstract: An information system comprising a first computer and a second computer, a first display screen and a display management device connected to the first screen. Each computer communicates with the display management device by means of a communication network. The display management device allows control of the display of information from the first computer or from the second computer on the first display screen. A tactile unit is applied to the first display screen and an additional communication network, which is separate from the communication network between each computer and the display management device, allows the tactile unit to communicate with the second computer so that a user is easily able to act on the information displayed on the first screen without the risk of interference with the rest of the system.
