A hydrodynamic clutch arrangement is provided with at least a pump wheel and a turbine wheel to form a hydrodynamic circuit in a clutch housing, the drive-side wall of the housing being connected on the side facing the drive unit, such as an internal combustion engine, to the drive unit, a clutch device being provided to bring the housing into or out of working connection with the pump wheel. Each multi-faceted segment has a length extending between two ends and a plurality of flat facets extending along the length including two outer facets defining a pivot edge that engages an apex between two internal socket walls and an internal facet facing inwardly and sized to engage a side of a multi-sided fastener. The first sliding unit is attached to the first base. An electronic control circuit conserves battery power by limiting the period of time that the LEDs are energized during nighttime hours when ambient lighting conditions cannot support the recharging function. The reticulated film of the invention is comprised of a series or network of small, geometrically profiled, depressed areas, wherein the depressed areas of the film are able to collect liquids such as blood, and channel such liquids through openings in the film layer into the associated absorbent layer.
