Abstract: A wheelchair lift apparatus that includes a stand that includes a pair of inclined rails; and a platform adapted to carry a wheelchair, wherein the platform includes a driving portion and a driven portion for moving the platform along the rails, wherein, when the driving portion actuates the driven portion in a first direction, the platform ascends along the rails, wherein, when the driving portion actuates the driven portion in a second and opposite direction, the platform descends along the rails.

Abstract: A lowerable window in an automotive vehicle has a guide and sealing system with a guide member attached substantially along the length of an edge of the window pane so as not to overlap with the outer surface thereof, the guide member having a guide conduit for interaction with a door channel having two prongs extending from vehicle door panels which define a channel portion therebetween. A guide member and the door channel are interposed such that the guide member receives a first prong of the door channel within the guide conduit and the door channel receives a guide edge within the channel portion. A seal member is mounted on the door channel so as to substantially fill a space between the guide edge and the first prong, and has at least three lip members, two of which extend laterally outward from the two prongs of the door channel so as to contact inward facing surfaces of the guide member.

Abstract: A magnetostrictive force sensor in which magnetically conductive support members are interposed between magnetically conductive end plates. The support members have magnetic properties which vary in accordance with the compressive or tensile load applied to them. The support members and end plates magnetically cooperate to create a magnetic circuit in which magnetic flux is induced by applying an alternating-current signal to a coil wound around one of the support members or by placing a permanent magnet into the magnetic circuit. When a load is applied to the magnetically conductive end plates, the magnetic properties of the support members vary to cause a change in the flux established in the magnetic circuit. The flux is detected by a second coil wound around the second support member, and the output signal detected by the detection coil is decoded to determine the load applied to the force sensor.
