Wheelchair lift which is installable both of steps and stairs
Published 2019-05-01“…Therefore, a stair and step lifting system were designed to satisfy these concepts as follows: 1) do not occupy the space in lower floor side, 2) stair and step common system, and 3) one degree of freedom mechanism. Based on these concepts, the proposed system has only one degree of freedom for driving rail to lift platform, and can be installed at both the stairs and the step by changing the inclination of the driving rail. …”

Multi-subject/daily-life activity EMG-based control of mechanical hands
Published 2009-11-01“…Recent research shows that it can be used to control even a dexterous polyarticulate hand prosthesis such as Touch Bionics's i-LIMB, as well as a multifingered, multi-degree-of-freedom mechanical hand such as the DLR II. In this paper we extend previous work and investigate the robustness of such fine control possibilities, in two ways: firstly, we conduct an analysis on data obtained from 10 healthy subjects, trying to assess the general applicability of the technique; secondly, we compare the baseline controlled condition (arm relaxed and still on a table) with a "Daily-Life Activity" (DLA) condition in which subjects walk, raise their hands and arms, sit down and stand up, etc., as an experimental proxy of what a patient is supposed to do in real life. …”
