摘要:
A system for accurately locating and positioning a person moving or standing still inside a hostile or severely damaged environment. For a person walking through any given environment, the location system continuously provides coordinates for positioning the person within the environment relative to the entry point thereof. The location system uses the morphological data of the person and integrates the person's movement in real time by acquiring features of the person's pace as the result of simultaneously combining the angles formed by the ankles, knees and hips of the person when walking, measured by electrogoniometers and interpreted according to a developed calculation method. The location system outdoes other existing solutions for locating a person in a difficult environment, such as, inside an underground building, partially collapsed and filled with opaque smoke, without the risk of faulty measurements, since it does not track by waves or by any vision-based system.
摘要:
A method of moulding a bioresorbable polymer for producing a bioresorbable medical device includes the following successive steps: (a) heating a poly(1,4-dioxanone) in the absence of any solvent of this polymer to a mass temperature between 145° C. and 165° C., (b) injection moulding the molten mass obtained in step (a) in a mould which is at a temperature of 80° C. to 115° C. lower than the mass temperature of the poly(1,4-dioxanone), (c) cooling the mould until solidification of the mass of poly(1,4-dioxanone), and (d) removing the thus obtained part from the mould. Also described is a moulded part which can be obtained by such a method as well as a medical device containing such a part.
摘要:
A porous composite product in the form of a film with a high specific surface. Used in a wide range of electrochemical products especially in the field of selective membranes, packaging or catalysis. The porous composite product has a high homogeneity in the distribution of the filler and a continuous structure. The product is capable of being obtained by extrusion.

摘要:
A process for producing N-formylleucine includes reacting leucine with formamide, precipitating the N-formylleucine, once the reaction is complete, at a temperature of approximately 0° to 40° C., by mixing the reaction medium with water and an acid, so that the final pH of the mixture is approximately 2 to 3, wherein the amount of water used in between approximately 1.5 and 5 parts per part by weight of starting formamide.

摘要:
The recoverable intra-uterine system comprises a housing capable of containing one or a plurality of elements selected from among the group comprising an embryo, male and/or female gametes, a fertilized oocyte, and unfertilized ovum and a combination of these elements, the housing having along an axis a distal end and a proximal end, and a device for holding the recoverable intra-uterine device in the uterus. The holding device is arranged at the proximal end of the housing and includes at least one holding arm in the uterine cavity capable of taking at least two positions: —one free position in which at least one holding arm is separated from the axis; and —a retracted position in which at least one holding arm is substantially parallel to the axis. Use in medically assisted reproduction techniques.
摘要:
A recoverable intra-uterine device comprising a housing containing one or several elements selected from a group containing an embryo, male and/or female gametes, a fertilised oocyte, an unfertilised egg and the combination thereof, wherein said housing is provided with a wall made of a biocompatible material. The wall is provided with a series of perforations whose size is sufficient in order to bring the intra-uterine medium into a cellular contact with the housing and to keep the elements therein. The inventive device is provided with a system for loading and unloading one or several elements selected from the group containing an embryo, male and/or female gametes, a fertilised oocyte, an unfertilised egg and the combination thereof.
