Abstract: An approach for determining link transmission quality identifiers is provided. For this purpose, a two-step approach is applied. In a first step, quality indicators are obtained from a black-box device and related signal are obtained and recorded. Based on the recorded data, a model can be established or a neural network can be trained. The generated model or the trained network may be used for determining further quality indicators at any arbitrary point in time.

Abstract: A method of conditioning and oxidatively dyeing human hair includes applying an oxidative hair dyeing composition to the human hair in order to dye the human hair and, simultaneously or subsequently to the applying of the oxidative hair dyeing composition, applying a particular hair conditioning composition to the hair. This hair conditioning composition has a pH value of from 3.4 to 3.9, which corresponds to an isoelectric point of the human hair, and contains from 0.001 to 2.5% by weight of a cationic polymer, an optional pH buffer and preferably additional conditioning ingredients, such as a cationic surfactant and/or a fatty alcohol.

Abstract: A rigid endoscope includes a jacket tube with an optical system and, parallel to the optical axis of the optical system, a first glass fiber bundle which emits a beam to illuminate an object to be examined. A second optical illumination system is directed at the object being examined. The second light exit of the second optical illumination system is recessed from the first light exit of the optical system by a distance greater than a diameter of the jacket tube. The light exit axis at the second light exit of the second optical illumination system is offset laterally relative to the image axis at the distal end of the optical system by an amount such that because of the resultant parallax and the shadow formation and unequal light distribution thus attained, the vividness of the image impression for three dimensional objects is increased.

Abstract: The cosmetic care preparation has a first component and a second component kept separate from the first component prior to application, which are mixed immediately prior to application on the hair and/or skin to form a ready-to-use product. The first component includes at least one conditioning ingredient, preferably one or more fats, oils and/or waxes, and the second component is a cationic or anionic base emulsion that includes at least one lipophilic substance, at least one cationic or anionic emulsifier, at least one organic acid and water. In a particularly preferred embodiment, the first component includes at least one cationic surfactant and/or at least one cationic polymer and the second component includes at least one monoalcohol and/or at least one amphoteric or nonionic surfactant.

Abstract: The hair treatment composition includes (A) at least one polydimethylsiloxane with hydroxy end groups, advantageously .alpha.-hydroxy-.omega.-hydroxy-poly[oxy(dimethylsilylene)]; (B) at least one volatile, linear or cyclic polydimethylsiloxane, advantageously octamethylcyclotetrasiloxane, and (C) at least one isoparaffin, advantageously an isomeric mixture of isododecanes. Also the composition is advantageously free of water or contains no more than 5 % water and is free of cross-linking agents. The composition forms a smooth protective film on hair which is treated with it, with brilliant luster, without loading the hair.

Abstract: The wax combination for the cosmetic compositions contains from 2 to 70 percent by weight of apple wax; from 5 to 70 percent by weight of orange wax and/or citric wax; and from 10 to 70 percent by weight of jojoba oil. The cosmetic compositions advantageously contain a portion of the wax combination in free form or an effective ingredient complex consisting of capsules, each containing some of the wax combination.

Abstract: The aqueous-alcoholic hair treatment composition contains 0.1 to 10 percent by weight of one or more film-forming ionic, anionic and/or amphoteric polymer; 0.1 to 9 percent by weight of one or more amphoteric surfactant; 0.1 to 40 percent by weight of one or more alcohol having 2 to 4 carbon atoms and 0.01 to 2.0 percent by weight of one or more organic acid. The aqueous-alcoholic hair treatment composition is also free of cationic surfactants. The aqueous-alcoholic hair treatment composition can be used as a permanent wave pre-treatment agent for treating hair prior to winding the hair on permanent wave curlers.

Abstract: The aqueous or aqueous-alcoholic hair treatment composition contains:A) 0.1 to 10 percent by weight polyvinylpyrrolidone or polyvinylpyrrolidone-vinyl acetate-copolymer;B) 0.1 to 9 percent by weight of at least one amphoteric surfactant, preferably a fatty acid amidoalkylbetaine or a fatty acid amidoalkylsulfobetaine;C) 0.1 to 5 percent by weight of at least one cationic surfactant, advantageously cetyltrimethylammonium chloride or bromide; andD) 0.1 to 2.0 percent by weight of at least one organic acid, preferably tartaric acid, glyoxalic acid, lactic acid or formic acid.

Abstract: The hairwax comprises a combination of(a) 10 to 41 percent by weight polyethylene glycol (M.W.=3000 to 5000).(b) 8 to 25 percent by weight hydrogenated castor oil which is ethoxylated with 40 to 60 moles ethylene oxide,(c) 36 to 51 percent by weight glycerol and/or ethyl hexanediol and/or polyethylene glycol (M.W.=100 to 300),(d) 0 to 15 percent by weight water.Our hairwax may also contain0 to 6 percent by weight of a cosmetic dyestuff and/or0 to 25 percent by weight of a pearl-luster pigment. The hairwax can be easily rinsed out of the hair but has good hairstyling properties.
