Abstract: The invention relates to a method for detecting a change in a patient's physiological condition with respect to a reference physiological condition. The method is based on a multimodal analysis that involves measurements of electroencephalography signals Si from the patient and at least one other physiological signal SN+1(N?1) from the patient. Based on these measurements, the invention proposes calculating distances di(m) associated with the electroencephalography measurements and with the measurements of the other physiological signals and fusing these data, the data having previously undergone a certain number of mathematical processing operations. In the context of the invention, the fused data may be assigned a weighting coefficient chosen according to one or more a priori or a posteriori criteria.

Abstract: A pressurized metered-dose inhaler requires good synchronization between the activation of the inhaler and the inspiration by the patient. Processing is carried out on the video frames filming the patient to qualify the actuation of the pressurized metered-dose inhaler according to two criteria: regarding the pressing by the patient's actuating fingers on a trigger member of the inhaler and regarding the actual compression of the inhaler. Processing of an audio signal recording the patient at the same time is also carried out to detect an inhalation by the patient. A temporal correlation of the probabilities obtained as results then makes it possible to qualify the synchronization between the actuation of the inhaler by the patient and the latter's inspiration, and thereby indicate a proper use or improper use of the inhaler.

Abstract: A method for detecting movements of a plurality of points (P) of a surface (21), comprising a measuring step during which an incident ultrasonic wave is emitted into the air towards the surface and an ultrasonic wave reflected into the air by the surface (21) is detected. During the measuring step, each measuring point is illuminated by the incident ultrasonic wave at a multiplicity of angles of incidence, and the reflected ultrasonic wave is detected by a network of receiving transducers (3) comprising a plurality of ultrasonic receiving transducers (3a). The movements of the surface are determined at a measuring point by determining a delay and/or a phase shift between two beam-forming signals for said measuring point.
