Abstract: A wheelchair lift for use in conjunction with a vehicle having a floor. The lift includes a power-actuating system, a platform assembly having first and second platform sections, a linking assembly having first and second vertical arms connected to the platform assembly, and first and second fold-facilitating links connecting the first and second vertical arms, respectively, to the first and second platform sections. The linking assembly connects the power-actuating system to the platform assembly. During a folding process, the first and second fold-facilitating links cause the first platform section to pivot with respect to the second platform section and the first vertical arm to move with respect to the second vertical arm.

Abstract: The invention relates to a method for the preparation of a composition of nanoparticles of at least one crystalline metal oxide from at least one organometallic precursor. One precursor(s) which can react spontaneously to oxidation is selected; a liquid solution of the precursor(s) is produced in a solvent non-aqueous medium, and the liquid solution is placed in contact with at least one oxidant in adapted reactional conditions in order to directly result in the production of nanoparticles of crystalline metal oxide(s). The invention also relates to a composition of nanoparticles obtained in the form of a colloidal liquid solution.

Abstract: The track assembly includes top plate 204, which incorporates the tracks 206. In FIG. 18, dashed lines have been added to show the portion of the top plate 204 that is used as the track 206 for the rollers 214. The interaction of the rollers 214 and track 216 is similar to the interaction of rollercoaster wheels and their associated track. In operation, small vertical rollers 214c ride against the side edge of top plate 204 (as can be seen in FIGS. 17a and 30a), small horizontal rollers 214b ride against the underside of top plate 204 (as can be seen in FIG. 30a), and the large horizontal roller 214a rides on the top of top plate 204 (as can be seen in FIG. 30a). This allows the moving tower 202 to travel from one end of the track assembly 200 to the other. As is described above, this rolling movement takes place when the platform 13 is folded and pulls the first vertical arm 42, and, therefore, the moving tower 202 inwardly.

Abstract: A ramp assembly for installation in a vehicle includes a ramp platform having a stowed configuration in the vehicle, a deployed configuration extending from the vehicle, and a lift and lock mechanism. The lift and lock mechanism is configured to lock the ramp platform in place when the platform is in a stowed configuration and to facilitate the lifting of the platform when the platform is deployed.
