Abstract: A user interface method, including presenting by a computer executing a user interface, multiple interactive items on a display. A first sequence of images is captured indicating a position in space of a hand of a user in proximity to the display, and responsively to the position, one of the interactive items is associated with the hand. After associating the item, a second sequence of images is captured indicating a movement of the hand, and responsively to the movement, a size of the one of the items is changed on the display.

Abstract: In order to provide an economical process for applying a coating to at least one side, optionally to both sides, of a leather, in which gentle processing of the leather is ensured and hardening thereof is avoided, an aqueous plastic dispersion having compact particles containing a blowing agent being applied to this side or these sides and being allowed to solidify, and hollow microspheres being formed from the thermoplastic compact particles by supplying heat, the invention proposes that, after solidification, the plastic dispersion containing the compact particles is subjected to the action of expanded superheated steam at a temperature between 80° C. and 100° C. (FIG. 2).

Abstract: A composite material has a polymeric upper layer which is connected via at least one adhesive layer to a substrate. The substrate is predominantly or entirely formed by an open-cell polyurethane foam onto which the upper layer, containing between 2 and 12 wt % of polysiloxane, is bonded by an adhesive layer. An intermediate layer or a double layer, i.e. a composite of the intermediate layer with a bonding layer located between the substrate and the intermediate layer, is provided between the upper layer and the substrate as the adhesive layer for joining the upper layer and the substrate. The regions of the substrate into which the polyurethane dispersion of the adhesive layer has penetrated in a controlled manner during application have a density which is between 12% and 48%, above the density of the regions of the substrate without the adhesive layer.

Abstract: A coated leather, in particular split cowhide leather, has a preferably nubuck-like appearing surface structure. The coating is formed with a surface layer formed with a mechanically and moisture-stable polymer and bonded to the surface of the leather or split leather by a polymer-based bonding layer. The outer layer is notable for inner smoothness and is formed with soft polyurethane. It includes in the non-embossed region microdepressions which are essentially closed in the direction of the leather but are open towards the outside, have an internal width of less than 130 ?m and are arranged close-packed to each other in the manner of soapy foam cells. The microdepressions are each separately bounded by thin mutually crosslinked stays which have on the outside a matt or finely fibrous fine-roughness structure surface, and have an essentially semispherical-shaped concave inner surface which faces outward and is smooth.

Abstract: The invention relates to a method for handling, namely forwarding and extracting, data, especially messages, in a system comprising at least one data source and a plurality of data receivers. The invention also relates to a corresponding system comprising at least one data source and at least one data receiver. At least one set of data, especially a message, is forwarded to a plurality of data receivers from a data source. According to the invention, when a set of data forwarded from the data source is acknowledged by one of the data receivers, said acknowledged data is preferably automatically extracted from the data source for the rest of the data receivers.

Abstract: A full-grained milled napa leather is provided on its grain side with a dressing formed from a solidified plastics dispersion. Required leather properties are still ensured and the production process is substantially simplified and more economical. First, the leather, such as cowhide, is subjected on a mechanically untreated grain side to a milling process for at least two hours. This results in a typical napa structure with a natural pebbled grain. Then, a polyurethane dispersion is applied to the grain side containing pigment particles and optionally further additives. Then the hide is allowed to dry. The solidified dispersion forming the dressing has a thickness of, preferably, from 0.05 mm to 0.07 mm.

Abstract: In order to provide leather with the desired cushioning properties and desirable soft handling properties, especially a grained leather with a grain structure on its upper surface, or a split leather with a surface finish, even if this leather is of minimal thickness, a foam layer is created on the non-visible underside surface of the leather. This foam layer is formed by applying a liquid plastic material containing means to create the foam and is subsequent solidified by removal of the solvent.

Abstract: In order to create a full grain napa cowhide which exhibits the characteristics with respect to grain pipeyness and water vapor permeability that are required by the automotive and upholstery industries, a finish is applied to the grain side of the full grain leather. The finish includes a pigmented layer with a thickness of between 0.015 mm and 0.04 mm and is formed of a stabilized polyurethane and/or polyacrylate dispersion. The dispersion contains microspheres with a diameter of less than 45 &mgr;m, which form primarily closed cells, and at least 10% open cells by volume. The top side of the layer is provided with a napa embossing. A second layer, placed on the first layer, is formed from a cross-linked polyurethane-based varnish application containing a dulling agent. The leather undergoes a milling treatment.
