A firefly simulation device which has a first depending flexible line segment, a motor driven fan at the distal end of the first depending flexible line segment, a second depending flexible line segment and an LED at the distal end of the second depending flexible line segment. The fan provides thrust in a plane normal to the first depending flexible line segment. The LED has a small light-transmitting opening able to be eclipsed by the LED body. In a darkened environment, the device provides apparent random motion and blinking of a light simulating a firefly.

Simulated firefly

A protective bank damming device useful for damming and controlling the flow of a liquid, the liquid most commonly being water. The damming device barrier member is inflated with water to provide a form to the barrier member, and anchoring weight to keep the barrier secured to the substrate surface. The barrier member provides support for a skirt member extending from the top side of the barrier to a skirt distal edge abutting against the flood side substrate surface. A skirt sealing means is applied along the skirt distal edge, with the purpose of preventing leakage under the skirt and barrier member, and utilizing natural leakage inherent in this type of liquid-anchored dam, reducing the hydrostatic pressure under the skirt and barrier relative to the dammed water. This pressure differential keeps the damming device securely anchored to the surface. Other embodiments include draining means formed in the construction of the barrier, and also a means by which the barrier may be secured to a substrate surface as a suction anchored damming device. The stability of this protective bank allows water to exceed the height of the dam, and a spillway is provided to re-direct the spill to a non-eroding direction on the dry side of the dam. Other features are parallel conjoined hose-casing barrier members formed of a single casing folded back with the open ends connected, allowing water to flow from one hose-casing section to the parallel attached casing section, and the folded back ends providing a naturally flat end profile perpendicular to the surface, and a profiling means for altering the end profile.
