This is about a new scheme for driving reflective bistable cholesteric displays (BCDs). It relies on fast switching from the planar state to the focal conic (FC) state, the two stable states in BCDs. The new scheme allows BCDs be driven using simpler electrical wave forms, and also making line add.....

It is important to be able to determine the longitudinal curvature (flare) of a foot and a shoe (or the shoe-last) in order to match or fit a shoe to a foot. The present invention is a device to determine and quantify the longitudinal flare on a foot or a shoe-last using two methods.A system is prov.....

It is necessary to be able to determine the shape of the foot surface when standing on different shapes so that the comfortable shapes can be determined. The foot is comprised of 26 bones and soft tissues and the optimal configuration for the foot when standing on a surface is really not its natural.....
