Abstract: Disclosed are methods for dermatological treatment of an area of skin of a subject that, in some embodiments, comprise moving a light director aperture in a prescribed direction relative to a skin surface and triggering a light source to produce a short-duration pulse of light and directing the produced short-duration pulse of light at a skin surface as a plurality of individual light beams every time the light director aperture travels a prescribed distance relative to the skin surface. Also disclosed are devices useful for fractional laser therapy to affect dermatological treatment that in some embodiments comprise a trigger functionally associated with a distance measurer functionally associated with a contact surface, the trigger configured to trigger a functionally-associated light source when a distance traveled by the contact surface along a skin surface is a prescribed distance.

Abstract: A portable, collapsible stretcher has frame poles, each of which have a medial joint which folds in one direction and two outer joints which fold in the opposite direction. A wedge is insertable into the medial joint to support the weight when the stretcher is extended. The outer joints have a locking mechanism which is operated by a linkage interconnecting the spreader bars and the folding legs. As the stretcher is extended, the outer joints are locked and the legs are unfolded from their normal position against the frame poles.
