  • Publication number: 20240012170
    Abstract: A detection system has an interface including a substrate supporting a conductive coating. Electrodes are provided to the substrate. A multiplexer provides current to the electrodes. A demultiplexer receives voltages from electrodes and provides corresponding signals to a controller. The controller receives these signals and determines therefrom an operation performed in connection with the interface by applying an algorithmic approach. Static interaction is recognizable, and machine learning can be used for gesture recognition and/or identification of other interaction types. The technology can be used in a broad array of applications, e.g., where it is desirable to sense interactions with a defined region such as, for example, in the case of touches, gestures, hovers, and/or the like.

  • Patent number: 11267751
    Abstract: A layer of or including substoichiometric zirconium oxide is sputter deposited on a glass substrate via a substoichiometric zirconium oxide inclusive ceramic sputtering target of or including ZrOx. The coated article, with the substoichiometric ZrOx inclusive layer on the glass substrate, is then heat treated (e.g., thermally tempered) in an atmosphere including oxygen, which causes the substoichiometric ZrOx inclusive layer to transform into a scratch resistant layer of or including stoichiometric or substantially stoichiometric zirconium oxide (e.g., ZrO2), and causes the visible transmission of the coated article to significant increase.

  • Patent number: 11112538
    Abstract: A first coating is provided on a first side of a glass substrate, and a second coating is provided on a second side of the glass substrate, directly or indirectly. The coatings are designed to reduce color change of the overall coated article, from the perspective of a viewer, upon heat treatment (e.g., thermal tempering and/or heat strengthening) and/or to have respective reflective coloration that substantially compensates for each other. For instance, from the perspective of a viewer of the coated article, the first coating may experience a positive a* color value shift due to heat treatment (HT), while the second coating experiences a negative a* color shift due to the HT. Thus, from the perspective of the viewer, color change due to HT (e.g., thermal tempering) can be reduced or minimized, so that non-heat-treated versions and heat treated versions of the coated article appear similar to the viewer.

  • Publication number: 20210215620
    Abstract: A method and/or system is provided for detecting inclusions (e.g., nickel sulfide based inclusions/defects) in soda-lime-silica based glass, such as float glass. In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, light is directed at the resulting glass and reflection of various wavelengths (e.g., red and blue wavelengths) is analyzed to detect inclusions.

In certain example instances, during and/or after the glass-making process, following the stage in the float process where the glass sheet is formed and floated on a molten material (e.g., tin bath) and cooled or allowed to cool such as via an annealing lehr, visible light from an intense visible light source(s) is directed at the resulting glass and thermal imaging is used to detect inclusions based on a temperature difference between the inclusions and surrounding float glass. In another example embodiment, inclusion detection may be performed without exposure of the glass to light from a light source(s).

  • Patent number: 10526242
    Abstract: Certain example embodiments of this invention relate to techniques for converting sputter-deposited TiNx or TiOxNy layers into TiOx layers via activation with electromagnetic radiation. An intermediate layer including TiOxNy, 0<y?1 is formed on a substrate. The intermediate layer is exposed to the radiation, which is preferentially absorbed by the intermediate layer in an amount sufficient to heat the intermediate layer to a temperature of 500-650 degrees C. while keeping the substrate at a significantly lower temperature. A flash light operated with a series of millisecond or sub-millisecond length pulses may be used in this regard. The converting removes nitrogen from, and introduces oxygen into, the intermediate layer, causing the layer to expand beyond its initial thickness. At least some of the final layer may have an anatase phase, and it may be photocatalytic. These layers may be used in low-maintenance glass, antireflective, and/or other applications.

  • Publication number: 20190276348
    Abstract: A method and/or system for reducing glass failures following tempering from inclusions, such as nickel sulfide based inclusions. During at least part of a cooling down period of a thermal tempering process, additional energy is directed at inclusion(s), such as nickel sulfide based inclusion(s), in the glass. The glass may be soda-lime-silica based float glass. The additional energy may be in the form of, for example, visible and/or infrared (IR) light from at least one light source that is directed toward the nickel sulfide based inclusion(s).

  • Publication number: 20190112698
    Abstract: Certain example embodiments of this invention relate to trim components having textured surfaces that support physical vapor deposition (PVD) deposited thin film coatings, and/or methods of making the same. A plastic substrate has a surface to be coated that is textured so that PVD-deposited layers formed thereon are generally conformal thereto and provide a desired matte or glossy aesthetic for the trim component. An adhesion promoting base layer and an overcoat sandwich a metal-inclusive layer, and each of these layers may be PVD-deposited on the textured plastic substrate surface. The adhesion promoting base layer and the overcoat are optional. Layers of metal, transition element, and/or other materials may be used to provide the desired coloration in certain example embodiments. The trim components may be used for interior and/or exterior vehicle or other applications, e.g., in connection with functional and/or decorative elements.

  • Patent number: 10125047
    Abstract: Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.
