Complex function device, producing method thereof , touch information system and information inputting device

The invention provides a composite functional device and manufacturing method, a touch sensation information system and an information input device. Regarding various touch sensation information like temperature, pressure, etc., the invention enables an touch sensation information processing similar to human beings with low cost without damaging elements in the wide applications in different fields such as the surface states of various concave convex graphics, paper, etc., the input device of an information machine. For this, strong dielectric substance or pyroelectrics capable of responding both to temperature and pressure is adopted, and one touch sensation information element can detect various temperature pressure information simultaneously. In addition, the invention can not only detect the information but also change part of or all of the detected touch sensation information into physical quantities equal to or different from the detected signal for reappearance through building the strong dielectric substance or pyroelectrics into a hollow structure of a cantilever beam or double supporting beam and electrifying the strong dielectric substance or pyroelectrics via an external power supply and the electrode.

The invention discloses a modeling method of a plate spring virtual model for force touch reappearance, which is characterized in that when the collision of a virtual agent to any one point on the surface of a virtual flexible body is detected, a plate spring virtual model is filled inside an interactive local region of the virtual agent and the virtual flexible body under the given virtual contact tension action, signals of force touch sensation information with the feedback reflected on real-time deformation simulation of the virtual flexible body under the pulling force effect and calculated by adopting the plate spring virtual model are output, the overlapping of the sum of all single plate spring deformation quantity in the plate spring virtual model for the force touch sensation reappearance is externally equivalent to the deformation on the surface of the virtual flexible body, and the sum of consumed tensions of all the single plate springs in the stretching process is equivalent to the given virtual contact tension. The modeling method has the advantages of accuracy, reliability, simple and convenient calculation, good practicability and good universality, can really feed back the force touch sensation information to operators, and realistically realizes the deformation simulation on the virtual flexible body at the real time.

Furniture wood board surface metallic paint spraying method

The invention provides a furniture wood board surface metallic paint spraying method. The furniture wood board surface metallic paint spraying method comprises the following steps that mixed priming paint is prepared, specifically, 0.1-0.5% of shish-kebab-structure polymer is added into acrylic paint, and uniform mixing is conducted; mixed finish paint is prepared, specifically, 10-20% of metal powder is added into the acrylic paint, and uniform mixing is conducted; primary polishing is conducted, specifically, the surface of a wood board is polished through a polishing machine, and thus, thesurface of the wood board is smooth; the priming paint is sprayed, specifically, the mixed priming paint is sprayed onto the surface of the wood board through a spraying technology, leveling is conducted, and after baking, a priming paint layer which is 25-40 [mu]m thick is formed; secondary polishing is conducted, specifically, the surface of the priming paint layer is polished through fine sandpaper so as to be smooth; and the finish paint is sprayed, specifically, the mixed finish paint adheres to the priming paint layer through the spraying technology, leveling is conducted, and after baking, a finish paint layer which is 100-120 [mu]m thick is formed. After metallic finish paint is sprayed onto the surface of furniture, the surface of furniture has metallic luster, the paint surface is high in stereoscopic impression and smooth when being touched with a hand, and the good visual effect and touch sensation are achieved.

Coating texture anti-counterfeiting paper

The invention discloses coating texture anti-counterfeiting paper, which comprises a raw paper layer, wherein a coating is formed on the raw paper layer through coating; the coating is prepared from the following ingredients in parts by weight: 0 to 20 parts of color developing agents, 10 to 30 parts of adhesives, 64 to 85 parts of fillers, 0 to 2 parts of water-retaining agents, 0.5 to 1 part of lubricating agents and 0.5 to 1 part of dispersing agents. In the coating process, coatings with different textures are coated. The coating texture anti-counterfeiting paper coated by the coating raw material in a special coating mode has the following characteristics that 1, through visual inspection, when the anti-counterfeiting paper is irradiated in a way of facing the sun, bright and dark patterns are shown on the paper surface, but ordinary paper does not have the bright and dark patterns; 2, through touch sensation, two surfaces of the anti-counterfeiting paper are both flat, do not have obvious convex-concave feelings and are different from that of ordinary water marked paper; the ordinary water marked paper has obvious convex-concave feelings; 3, when a microscope is used for observation, the detected outline is anastomotic with the outline of a standard pattern; 4, a special probe for measuring the thickness is used for detecting the thinnest position and the thickest position of a detected pattern, and data is different.
