An improved dispenser for thin, flexible hand coverings includes a unique mechanism to retain the opposing edges of the flexible film as it is advanced and applied to the hand, thereby promoting a controlled stretching, adherence and release. Each of the lower core assy and the upper core assy is unitarily formed so as to have a predetermined shape by resin-molding a core and a coil that form an electromagnet as well as an armature bearing, etc. Analysis can include, for example, generating a thickness map, a cartilage curve, or a point cloud. A photosensor element may be located inside the housing and adapted to be optically coupled to the scintillator. Frame processing further refines the current background model by determining whether a substantial change has occurred in the actual background and, if so, providing a more accurate background model.
