  • Publication number: 20250093134
    Abstract: A method of determining a score of a dart in a play surface of a dartboard using a plurality of cameras facing the dartboard is provided, wherein a direction of view of each of the plurality of cameras is at a non-zero angle relative to a plane containing the play surface of the dartboard, the method comprising: calculating a homography matrix for each camera within the plurality of cameras, the homography matrix being for transforming an image of the dartboard captured by the respective camera from a view of the respective camera to a front-view of the dartboard; capturing a first image of the dartboard using each of the cameras at a first time, and capturing a second image of the dartboard using each of the plurality of cameras at a second time, the second time being subsequent to the first time, and the dart being in the play surface of the dartboard at the second time; producing a plurality of differential scoring images by comparing each first image to the second image captured by the respective camera;

  • Patent number: 9353005
    Abstract: The present invention relates to a process for the production of powders redispersible in water comprising an organic component and a water-soluble organic polymeric protective colloid. The organic component is dispersed and stabilized with the protective colloid in water to form a stable dispersion which is dried to form the powder redispersible in water. The organic component comprises abietic acid, sylvic acid, neoabietic acid, levopinaric acid, pimaric acid, isopimaric acid and/or palustric acid and/or their derivatives. The water-soluble organic polymeric protective colloid comprises synthetic protective colloids and naturally and/or synthetically produced biopolymer which can be synthetically modified. The obtained powder reduces efflorescence in hydraulically set systems.

  • Patent number: 8119195
    Abstract: The present invention pertains to the use of quaternary organic ammonium compounds for the reduction of efflorescence in building materials. In addition, a mixture containing at least one quaternary organic ammonium compound and at least one water-soluble organic polymer and, optionally, further additives is described. The mixture according to the invention can be prepared by a) at least one quaternary organic ammonium compound and at least one water-soluble organic polymer being mixed with one another in water and the obtained aqueous mixture optionally being subsequently dried, or b) at least one powdery quaternary organic ammonium compound and at least one powdery water-soluble organic polymer being mixed with one another, or c) at least one liquid and/or dissolved quaternary organic ammonium compound being applied on at least one powdery water-soluble organic polymer, in particular by means of spraying, adsorption, mixing, fluidized bed drying and/or granulation.

  • Publication number: 20090223416
    Abstract: The present invention relates to an additive for hydraulically binding systems for reduction of blooms in hydraulically bound systems, which is preferably present as a powder redispersible in water and is suitable in particular as additive for addition in dry mortars. The powder redispersible in water consists of at least one organic component and at least one water-soluble organic polymeric protective colloid and also if appropriate further additives, with the organic component containing at least one compound having a cyclic group which is completely or partially saturated and having a melting point of about ?20 to 250° C. and also a molecular weight of about 100 to 10 000, and forming a stable dispersion in water with the water-soluble organic polymeric protective colloid, with the weight ratio of the organic component to the water-soluble organic polymeric protective colloid being about 95:5 to 5:95. The invention also relates to a process in which the drying step is omitted.
