Fibers, such as textile fibers, having electrical components deposited thereon. More particularly, one or more electrical components are formed directly onto the surface of at least one fiber. The fiber having the electrical component formed thereon may then be interlaced with other fibers to form a larger piece of fabric, which can be employed to produce an article of clothing. A group of transistors and piezoelectric components forming an accelerometer may be woven onto one or more natural or synthetic fibers. The fibers may then be employed as the warp, weft, or both, of a woven piece of fabric, or used to form a knitted piece of fabric. The fabric piece can then be cut and sewn to form a wearable item, such as a shirt, a pair of pants, a hat, or the upper piece of a shoe that includes the accelerometer.

A process for applying digitally printed applique” indicia which results in decorative and identification elements for decoration and identification when applied to uniforms, fashion, “basic” and performance apparel, swimwear and intimate apparel as well as other textile products, the elements being an alternative to direct embroidery, embroidered emblems, thermo-transfer films, silk screen or sublimated printing. The production process includes the following phases (FIGS. 3A-C): a design phase (1); a separation phase (2); a printing phase (3); an optional traditional embroidery phase (4); and an etching / cutting phase (5). The process can incorporate embroidered elements but has the benefit of reducing or eliminating portions of stitching and or extra applique layers in the emblem. The resulting product has superior care and durability characteristics to screen printing and heat transfers as the image is more wash fast and can be ironed. The heat or pressure transfer capability can allow much faster customization of finished garments.

Disclosed are methods and apparatus for cleaning a substrate, such as a fabric material, involving the application of optical energy to the substrate, typically in the form of a beam of light, where the energy of the beam causes removal of the contaminant from substrate, such as from the fibres of a fabric material. The cleaning may occur via any mechanism, including one or more of, alone or in any combination, ablation, melting, heating or reaction with the substrate or contaminant or agent introduced to aid in the cleaning. The optical energy is typically applied to a selected area of the substrate (e.g., as a beam), and the substrate and beam or optical energy source moved relative to one another so as to clean a larger area of the substrate, either by moving the substrate or the beam, or both. Movement of the beam with respect to the substrate can be attained through a beam scanning mechanism or through movement of the optical source itself.
