Abstract: Method and system for underwater hyperspectral imaging of seabed impact, environmental state or environmental footprint from natural or man-made sedimentation comprising hyperspectral imaging of ecological, chemical or sediment indicators in an observation area and identifying and classifying ecological, chemical or sediment indicators in the observation area.

Abstract: An apparatus for placement on or in a body of water for hyperspectral imaging of material in the water comprises an artificial light source and a hyperspectral imager. These are arranged so that in use light exits the apparatus beneath the surface of the water and is reflected by said material before re-entering the apparatus beneath the surface of the water and entering the hyperspectral imager. The hyperspectral imager is adapted to produce hyperspectral image data having at least two spatial dimensions.

Abstract: An apparatus for forming loose fill packing material which comprises a shredder device operative to convert sheets of corrugated cardboard into elongated, thin paper strips which are discharged onto a perforated conveyor movable between a loading position at the shredder device and a discharge position where the strips are emptied into a collection hopper. A suction device is mounted beneath the conveyor, downstream from the shredder device, which is operative to apply a suction to the cardboard strips to remove dirt, dust and other foreign materials therefrom, and then the cleaned paper strips are transmitted along an angled sifter plate having a plurality of openings which are sized to allow undesired, short strips of paper to pass therethrough for deposit into a waste hopper. A spraying device is located at the sifter plate to deposit a liquid material on the paper strips having microbicidal, sanitizing, insect repellant, disinfectant and deodorizing properties.

Abstract: This invention is directed to loose fill packing material comprising clean, elongated strips of paper formed from sheets of corrugated cardboard by an apparatus which comprises a shredder device operative to convert the sheets of corrugated cardboard into paper strips for discharge onto a perforated conveyor movable between a loading position at the shredder device and a discharge position where the paper strips are emptied into a collection hopper. A suction housing is mounted at the outlet of the shredder device in position to substantially enclose the conveyor so that a suction can be drawn over the paper strips to remove dirt, dust and other foreign materials therefrom after which the cleaned paper strips are transmitted by the conveyor to an angled sifter plate having a plurality of openings which are sized to allow undesired, short strips of paper to pass therethrough.
