Abstract: The invention relates to a protection device for a needle of an assembly or of an injection device having a hub portion provided with a needle, the said protection device comprising: an outer casing formed of a first material; and an inner casing formed of a second material different from the said first material and defining a cavity for receiving in a sealing way at least the hub portion, said cavity having an inner wall; attachment means defined in the said cavity to removably engage and secure said protection device at least along a sealing line to the injection device; the protection device being characterized in that it further comprises aspiration limiting means for limiting the deformation of said cavity when said protection device is separated from the assembly or the injection device.

Abstract: A classification method including first classifying an event of any kind by first rules, and then second classifying events, not identified by the first classification, by a learning base reinforced with all the events identified by the first classification. The method is adaptive if the second classification rules are amended according to new examples that were able to be determined by the first rules.

Abstract: A method and device for analyzing a gait of a person includes a magnetometer for fastening to a tibial segment of the person, in order to generate a signal representative of at least one projection onto a sagittal plane of an ambient magnetic field in which the magnetometer is immersed and a signal processor to identify instants and/or phases that are characteristic of the gait of the person by identifying particular points in the signal generated by the magnetometer as a function of time.

Abstract: This method uses two sets of sensors to estimate certain characteristics of the movement of a device or a person or states, especially postures, they adopt. A first, abundant, set of sensors (1) is removed after a learning phase where it records with certainty the states obtained by interpreting first decisional rules. The measurements of a second set of sensors (2), much more restricted than the first, are correlated to the states reached during the learning period by second decisional rules automatically obtained by supplying a classifier. They are then interpreted to determine the new states reached by the wearer just by means of the second sensors. The results are good in spite of the low number of second sensors, thanks to the accuracy of the second decisional rules.

Abstract: A sensor worn by a person measures movements of the person. Movements of orientation are not expressed by rotations leading from a stationary reference point to a reference point associated with the sensor, but by angles separating axes or planes of the stationary reference point and axes associated with the wearer, thereby making it possible to better identify his/her movements and his/her activity. The sensor can be applied to the monitoring of patients.

Abstract: A device for analyzing the gait of a person, wherein the device comprises: a magnetometer for fastening to a tibial segment of said person, in order to generate a signal representative of at least one projection onto a sagittal plane of an ambient magnetic field in which it is immersed; and signal processor means for identifying instants and/or phases that are characteristic of the gait of said person from said signal generated by said magnetometer. Advantageously, said signal processor means are adapted to identify characteristic instants of the person's gait by identifying particular points in the expression as a function of time for said signal generated by said magnetometer.

Abstract: A first light source has a first wavelength corresponding to an excitation wavelength of a fluorophore. The excitation wavelength and an emission wavelength of the fluorophore delineate a predetermined interval. A second light source has a second wavelength offset with respect to the first wavelength so as to be outside said predetermined interval. The offset between the first and second wavelengths is comprised between 30 nm and 100 nm. A camera comprises a filter opaque to the first and second wavelengths and transparent to the emission wavelength and to wavelengths substantially higher than the higher of the first and second wavelengths. The light sources and camera are synchronized to alternately activate one of the light sources and make the camera alternately acquire a fluorescence image and a background noise image.

Abstract: A method for detecting a substantially invariant rotation axis of a motion of a mobile body equipped with at least one inertial or magnetic sensor with three sensitive axes that includes acquiring physical measurements with respect to the three sensitive axes of the sensor, the physical measurements including at least three samples at different times, estimating a substantially invariant rotation axis in the physical measurements space, and identifying the estimated axis as the substantially invariant rotation axis of the motion. In one aspect, the method is applicable for estimating the motion of a mobile body rotating about a substantially invariant axis.

Abstract: A person under supervision wears a sensor consisting of at least one accelerometer (31) and a magnetometer (41), oriented in his vertical direction. A fall event is picked up when a significant and rapid oscillation of the acceleration signal coincides with a shift in the ambient magnetic field between two levels (between t=4000 and t=5000). Additional criteria that may also make use of the magnetometer enable the diagnosis to be made, and it is easier and safer to establish this than with accelerometers alone.

Abstract: Measurements of a mobile object and particularly a living being are made using two techniques, normally radiation attenuation and radiation emission, in synchronisation to provide images of the object state. Movement displacement fields from one phase to the next are estimated for both techniques, but the final images obtained by the emission technique are improved by the knowledge of the displacement field obtained by the other technique that is more precise.
