The present invention relates to an alignment jig for aligning leather sheet and a Velcro structure before sewing to couple the leather sheet and the Velcro structure which form a vehicle seat cover. The guide part having the accommodation groove into which the Velcro structure can be inserted and fixed is formed on the lower plate of the alignment jig, and the penetration part is formed in the upper plate thereof. Accordingly, after the Velcro structure is inserted and fixed into the accommodation groove of the guide part, when the leather sheet is placed thereon and the upper plate is closed, the leather sheet and the Velcro structure are aligned automatically, and then, when sewing is performed through the penetration part of the upper plate, the Velcro structure can be accurately aligned and coupled on a predetermined curved path of the leather sheet.

A system of fabric-based devices designed as transistors with tri-state behavior that can measure any geometries on 2D and 3D surfaces. The devices are constructed from layers of conductive materials and flexible sheets that allow signals to selectively cross between layers. Multiple layers of conductive signals can be achieved by controlling the tension of the top and bottom thread, and interlayering conductive, semiconductive, insulating, and semi-porous materials around a sensing layer. The layers can be further modified to include folds and cuts that allow for 2D and 3D bending, stretching, twisting, and curves. Large sheets of devices can be organized into grid-like matrixes, with signal wires connected in a multiplexed fashion to minimize the amount of threads to simplify construction and device communication to a central processing unit.

An active-insulation paneling component and garments including an active-insulation paneling component. The active-insulation paneling component includes insulated panels separated by gussets. The gussets are configured to expand upon an outward pulling force to allow the active-insulation paneling component and/or garment to expand even where the active-insulation paneling component and/or garment are not manufactured from elastic materials.
