Abstract: Compression bandage for use as the only bandage in a single-bandage system for compression therapy, comprising an elastic compression layer and an elastic comfort layer, of which at least 50% is permanently attached to the compression layer. The compression bandage has a full-stretch elongation (FSE) of between 25% and 60% beyond its unstretched length. Full-stretch elongation is defined as the elongation at which the second derivative (130) of a curve (110) showing tensioning force over longitudinal elongation has its global maximum (140).

Abstract: A tarpaulin alarm system triggered by unsnapping a tarpaulin attachment snap from a snap member includes a hollow housing on which the snap member is mounted and a Hall effect sensor arranged proximate the snap member on a printed circuit board contained within the housing for cooperation with a magnet associated with the attachment snap. The housing is preferably cylindrical in shape for easy mounting in a drilled hole. The printed circuit board is connected to a switched power source external to the housing, and may be wired to a suitable alarm indicator, such as an existing horn. The circuitry includes an oscillator-based timer for providing a delay period after triggering during which the system may be reset by re-attaching the attachment snap to the snap member.
