Abstract: A foot lifter orthesis including a dorsal leg shell, extending over the rear foot, which can be fixed by a strapping means to the calf of the orthesis wearer and which has a forefoot shell section constructed in one piece which extends to a point below the foot sole region, wherein the leg shell exhibits a low resistance in dorsal foot bending and a high resistance compensating for the foot and shoe mass in plantar foot bending with at least one resilient inlay, which extends approximately parallel to and at a short distance from an edge of the leg shell from the calf region thereof to a point below the forefoot shell section. An associated method of formation is also disclosed.

Abstract: The invention relates to a device producing a stance flexion. This goal is achieved according to the invention by virtue of the fact that in the initial position of the multi-element joint system one element (joint element) can execute two movements with respect to the other elements (joint elements) connected to it, with at least one movement, after its initiation, at least predominantly blocking the other possible movement.

Abstract: An electromechanical transducer having a first element movable in relation to a second element, wherein the first and second elements perform a translational movement relative to one another. A transducer element mechanically coupled to the first element and second elements for converting the translational movement into an electrical signal. A transmission element converting the relative translational movement of the first and second elements into a rotating movement of the transducer element so as to produce the electrical signal.Applicant claims, under 35 U.S.C. .sctn.120, the benefit of priority of the filing date of Jun. 17, 1991, of International Patent Application PCT/NL91/00099, copy attached, filed on the aforementioned date, the entire contents of which are incorporated herein by reference.
