Abstract: An animal husbandry system for a group of animals that can move about freely in an area. The system contains at least one illumination unit, each illumination unit contains a mounting structure provided with a number of illumination elements, and each is arranged for illuminating a respective subarea. The system also contains at least one camera arranged for monitoring a number of subareas, where the camera(s) is (are) arranged for repeatedly determining the illumination intensity at one or more reference surfaces in the area. The system further contains a control means, operatively connected to the illumination elements and to the camera(s), and the control means is programmed for adjusting the illumination elements, based upon the determined illumination intensity at the reference surface(s), in such a way that a predetermined desired illumination intensity pattern is achieved in the area.

Abstract: The invention relates to a binder polymer obtainable by copolymerizing a monomer mixture comprising a vinyl monomer M1 and a butenolide monomer M2, wherein the vinyl monomer M1 is a vinyl ether, a vinyl ester, or a combination thereof, and wherein the butenolide monomer M2 is a 5-alkoxy-2(5H)-furanone. The invention further relates to a coating composition comprising such binder polymer and to a substrate coated with a coating deposited from such coating composition.

Abstract: The present application relates generally to pumps, and more particularly to piston type pumps having increased energy efficiency, systems incorporating such piston type pumps, and methods of operating piston type pumps.
