Abstract: A cover for a sink that has a faucet and spout comprises a sheet flexible material with top surface and bottom surfaces; one or more openings positioned near an edge of the cover, the sheet of flexible material sized to fit over the sink, the one or more openings sized to receive the faucet and the spout therein, and may include a waterproof backing Embodiments include elastic to form a secure fit, and closures such as adhesive tabs or handle ties. The cover fits over a sink to cover it, a faucet and a spout, so that waste from a grooming activity, or other action, is collected in the cover and not deposited in the sink, the adjacent area, and/or the floor.

Abstract: A laser shielding device is disclosed, having two spaced-apart layers of shielding material defining a sealed chamber between the two. At least one layer will degrade in the presence of an impinging laser beam, creating a hole through the layer. A pressure change in the chamber is sensed and signaled to a machine controller to stop the lasing operation.
