    • A knee brace has a pair of femoral and tibial links and a four bar joint mechanism by which a lateral side one of the femoral links is pivotally connected to a lateral side one of the tibial links and a four bar joint mechanism by which a medial side one of the femoral links is pivotally connected to a medial side one of the tibial links. Each of the joint mechanisms comprises an inner, padded, pivot plate and an outer pivot plate, each of end of which is pivotally connected at a single point to a respective one of the femoral and tibial links. Furthermore, the pad on the inner pivot plate of the medial side joint mechanism carries a spherically cupped femoral condyle pad by which the brace, generally, and the joint mechanism, specifically, can be properly positioned relative to the knee of the wearer. The locations of the pivot points for the pivot plates on the links are set in accordance with parameters which are designed to produce a multiaxis motion of a reference point which will constrain the tibia to slide rearwardly relative to the femur in an initial range of flexion of the knee from a straight leg position and then to rotate relative thereto along an arcuate path. Additionally, the angle between imaginary lines through the pivots of each pivot plate is caused to be greater than a predetermined minimum value which will insure that the joint mechanism has sufficient strength not to break apart in use due to loads which are imposed horizontally across the knee joint.

    • Laying optical waveguides into sinuous grooves of a support filament while holding the grooves in the same position as the filament passes through a waveguide laying station by causing the filament to twist in oscillatory fashion during passage through the station. The grooves are held in the same positions by positionally fixed guide projections located in the grooves. By this laying method, the waveguides themselves are not oscillated around the support filament as they are fed into the laying station. Also, guide elements to feed the waveguides into the grooves extend downstream to a wrapping station whereby tape wrapped around the support filament also is wrapped around the guide elements. The waveguides exit from the guide elements after the tape has been wrapped.
    • 将光波导放置在支撑细丝的弯曲槽中,同时通过使灯丝在通过台阶期间以振荡的方式扭曲,同时将槽保持在与灯丝通过波导铺设站相同的位置。 凹槽通过位于凹槽中的位置固定的引导突起保持在相同的位置。 通过这种铺设方法,当它们被馈送到放置站时,波导本身不会在支撑细丝周围振荡。 此外,将波导馈送到凹槽中的引导元件在下游延伸到包装站,由此缠绕在支撑丝线周围的带也缠绕在引导元件周围。 在带被包裹之后,波导从引导元件离开。
