Abstract: The orthosis (10) comprises: a foot portion (12); a leg portion (14) exerting a therapeutic compression textile pressure on the leg; and a rib-knitted end portion (16) locally exerting a holding textile pressure for preventing the terminal portion from sliding downwards under the effect of the elastic return force. (F) from the leg portion that is stretched in the longitudinal direction. The method comprises obtaining data representative of: morphological characteristics of the limb; rheological characteristics of the leg portion of the orthosis; friction characteristics at the interface between the limb and the leg portion of the orthosis; rheological characteristics of the end portion of the orthosis; and friction characteristics at the interface between the limb and the end portion of the orthosis.

Abstract: The orthosis includes a compressive portion having an ankle portion that, when worn, exerts a nominal textile pressure P0 for an ankle circumference C0. When it is stretched in order to enable it to go past the instep region of the leg, the ankle portion exerts an elastic return force in the circumferential direction corresponding to a nominal putting-on textile pressure P1 for an instep circumference C1. At least one parameter selected from: the natures of the core yarns used for said knit yarn and said weft yarn; any covering of said yarns; and the knitting of said yarns; is selected in such a manner that for C1=1.38C0, said nominal putting-on textile pressure P1 is less than or equal to 120% of said nominal wearing pressure P0. This makes it easier for the patient to put on and take off the orthosis merely as a result of the intrinsic properties thereof and without having recourse to any accessory.

Abstract: An online sensor for monitoring chemical contaminations in hydraulic fluids, having a receiving device for the fluid to be monitored, the device having observations windows disposed on two opposite sides, is characterized in that the online sensor has an IR emitter and an IR detector comprising at least two, preferably four detector fields for IR spectroscopy, wherein the fields are disposed opposite of each other on both observations windows. This provides a sensor that is capable of detecting the maintenance-relevant parameters of hydraulic fluids based on phosphate esters online, which is to say without having to withdraw the same from the airplane's hydraulic system and remove the same as a sample.

Abstract: This orthosis comprises a compressive leg portion extending upwards from the ankle. The structure of the row of stitches ensures a uniform distribution of the resilient return forces at the circumference of the orthosis around an outline corresponding to a horizontal section of the limb. The stitch structure and the dimensioning of the leg portion are selected in such a manner as to apply on a region (R) extending between the ankle and the knee, a therapeutic pressure once the orthosis has been put on the limb. The mean pressure Pc exerted on the center third (RC) of said compression region is greater both than the mean pressure Pb exerted on the distal third (RD) and than the mean pressure Pd exerted on the proximal third (RP) of said region, Pc, Pb, and Pd being the pressures exerted at the respective heights of points c, b, and d of the Hohenstein model.

Abstract: The orthosis comprises a leg portion and a foot portion. The leg portion which extends upwards from the ankle serves to apply therapeutic compression to the leg once the orthosis has been put on. The foot portion which extends from the malleolar region to the toes and covers the instep is a shaped portion that envelops the foot elastically. The dimensioning and the mesh structure of the foot portion are such that 0<Px<Pm<Pb once the orthosis has been put on, Px being the pressure applied to the instep region, Pm being the pressure applied to the malleolar region, and Pb being the therapeutic compression applied to the ankle region. Preferably, Px=5 mmHg±25% and Pm=0.5(Pb+Px)±25%.
