Abstract:
An article of apparel is disclosed that includes a textile with at least one property that changes upon exposure to a physical stimulus. The textile has a modifiable structure formed from one or more yarns that exhibit a dimensional transformation upon exposure to the physical stimulus. The yarns have a first set of dimensions when unexposed to the physical stimulus, and the yarns have a second set of dimensions when exposed to the physical stimulus. The structure of the textile is modified by exposing the textile to the physical stimulus such that the yarns transform from the first set of dimensions to the second set of dimensions and change the property of the textile. Reinforcing structures, incisions, partial incisions, and coatings may also be utilized to enhance the textile structures.

Abstract:
A camouflage system to be used for both military uniforms and equipment. The system includes specialized means of printing the camouflage system unto fabric. The system can also be used for civilian applications, particularly with sportsman hunters. The system provides camouflage in both the human visible light range and the infrared. The system depends on the use of a macro-pattern resulting from a repeat of a micro-pattern. When applied to fabric, a polyamide-cotton fiber blend has a macro pattern resulting from a repeat of a micro pattern printed on at least one surface. The coloring system used comprises at least four colorings from dyes that in combination produce a percent reflectance value comparable to the negative space of the surroundings near the camouflaged subject. The system functions by a macro pattern being disruptive of the shape of the subject and a micro pattern comprising sharp edge units of a size capable of blending the subject into the background. The relative lightness values and percentages of total pattern are sufficient to produce a percent reflectance of acceptable colors, wet or dry in terms of lightness values compared to current military four-color camouflage. On fabric, the results are achieved by printing A macro pattern that disrupts the sensed shape and a micro pattern with a repeat size that produces the macro pattern. The reflectance of the material is comparable to the negative space surrounding a subject so the subject does not appear too dark or too light (out of place). The variation in the lightness between wet and dry is not greater than 17-28%, achieved during the printing process.

Abstract:
The dielectric device includes a substrate, a lower electrode, a dielectric layer, and an upper electrode. The lower electrode is bonded onto the substrate. The dielectric layer is bonded onto the lower electrode. The dielectric layer is obtained through thermal treatment of a film layer formed by spraying of a powdery dielectric material and a fine-particulate metal. In the thus-formed film layer, the metal is dispersed in the matrix of the dielectric material. Thermal treatment of the film layer causes migration of the metal in the film layer. This metal migration causes a lower-electrode-adjacent portion and upper-surface-adjacent portion of the dielectric layer to have different metal contents.

Abstract:
Thermostructural composite structure having a compositional gradient, formed from a porous core (5) made of a refractory having a pore volume content of greater than or equal to 80%. The core (5) lies between two intermediate layers (6a, 6b) comprising the carbon fiber reinforcement, densified by a matrix composed of the carbon phase and of a ceramic phase, and a refractory solid filler. Two monolithic ceramic shells (7a, 7b) cover the intermediate layers in order to give stiffness to the entire structure.

The invention concerns a manufacturing method including providing a foam layer (18) on a surface of a mold part (10), while the mold is open, closing the mold so that it defines a cavity between the foam layer (18) and another mold part (14), and injecting into the cavity a non-cellular plastic material designed to form the support (20). The method includes, after injecting the plastic material of the support (20), a step of gradually spacing apart at a predetermined speed the two parts of the mold (10, 14), in a direction having a component in the direction of the thickness of the foam layer (18). The invention is applicable to motor vehicle interior trims.

Abstract:
A heat collector includes a heat absorption surface, an opposite heat focus surface and one or more surrounding sides. A matrix of the heat collector is a thermally conductive material. There is a plurality of adiabatic pores mixed within the matrix. A relative concentration distribution of the adiabatic pores increases from the heat absorption surface to the heat focus surface, and decreases from the surrounding sides to a center of the heat collector. The shape of the heat collector can be rectangular, cylindrical, prismatic, plate-shaped, square, or polyhedral. The heat collector can draw heat generated from electrical components, and collect the generated heat for reuse in order to enhance energy efficiency.
