[0014] Reference will now be made in detail to certain embodiments of the disclosed subject matter, examples of which are illustrated in part in the accompanying drawings.

While the disclosed subject matter will be described in conjunction with the enumerated claims, it will be understood that the exemplified subject matter is not intended to limit the claims to the disclosed subject matter.

[0015] Throughout this document, values expressed in a range format should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a range of“about 0.1% to about 5%” or“about 0.1% to 5%” should be interpreted to include not just about 0.1 % to about 5%, but also the individual values (e.g., 1%, 2%, 3%, and 4%) and the sub-ranges (e.g., 0.1% to 0.5%, 1.1 % to 2.2%, 3.3% to 4.4%) within the indicated range. The statement“about X to Y” has the same meaning as“about X to about Y,” unless indicated otherwise. Likewise, the statement“about X, Y, or about Z” has the same meaning as“about X, about Y, or about Z,” unless indicated otherwise.

[0016] In this document, the terms“a,”“an,” or“the” are used to include one or more than one unless the context clearly dictates otherwise. The term“or” is used to refer to a nonexclusive“or” unless otherwise indicated. The statement“at least one of A and B” has the same meaning as“A, B, or A and B.” In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Any use of section headings is intended to aid reading of the document and is not to be interpreted as limiting; information that is relevant to a section heading may occur within or outside of that particular section

[0017] In the methods described herein, the acts can be carried out in any order without departing from the principles of the disclosure, except when a temporal or operational sequence is explicitly recited. Furthermore, specified acts can be carried out concurrently unless explicit claim language recites that they be carried out separately. For example, a claimed act of doing X and a claimed act of doing Y can be conducted simultaneously within a single operation, and the resulting process will fall within the literal scope of the claimed process. [0018] The term“about” as used herein can allow for a degree of variability in a value or range, for example, within 10%, within 5%, or within 1% of a stated value or of a stated limit of a range, and includes the exact stated value or range.

[0019] The term“substantially” as used herein refers to a majority of, or mostly, as in at least about 50%, 60%, 70%, 80%, 90%, 95%, 96%, 97%, 98%, 99%, 99.5%, 99.9%, 99.99%, or at least about 99.999% or more, or 100%.

[0020] Various embodiments according to the present disclosure relate to a glass laminate. The glass laminates described herein have discrete regions in which at least one region is adapted to have a high percentage of light in the infrared radiation range that is capable of being transmitted therethrough. The high percentage of light in the infrared radiation range that can be transmitted through the glass laminate can allow the glass laminate to be used in conjunction with a light detection and ranging (L1DAR) system.

Conventional glass laminates may not be compatible with L1DAR systems as the materials used in these conventional glass laminates allow a comparatively low percentage of light in the infrared radiation range to transmit therethrough.

[0021] FIG. 1 is a top view of glass laminate 100. Glass laminate 100 includes first region 102 and second region 104. First region 102 is adapted to have a high percent of transmission of light in the infrared range that is capable of being transmitted therethrough. For example, according to various embodiments, first region 102 is adapted to have a percent transmission of light, having a wavelength in a range of from about 800 nm to about 5 pm, in a range of from about 70 percent to about 100 percent, about 90 percent to about 99 percent, less than, equal to, or greater than about 70 percent, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91 , 92, 93, 94, 95, 96, 97, 98, 99, or about 100 percent. According to various embodiments, the light can have a wavelength in a range of from about 850 nm to about 5000 nm, about 900 nm to about 1550 nm, less than, equal to, or greater than about 800 nm, 850 nm, 900 nm, 1000 nm, 1500 nm, 1550 nm, 2000 nm, 3000 nm, 4000 nm, or about 5000 nm.

[0022] Second region 104 is adapted to have a high percent of transmission of light in the visible range transmitted therethrough. For example, second region 104 is adapted to have a percent transmission of light, having a wavelength in a range of from about 380 nm to about 780 nm, in a range of from about 70 percent to about 100 percent, about 80 percent to about 95 percent, about 85 percent to about 90 percent, less than, equal to, or greater than about 70 percent, 71 , 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, or about 100 percent. According to various embodiments the light can have a wavelength in a range of from about 400 nm to about 700 nm, about 500 nm to about 600 nm, less than, equal to, or greater than about 380 nm, 390, 400, 410, 420, 430, 440, 450, 460, 470, 480, 490, 500, 510, 520, 530, 540, 550, 560, 570, 580, 590, 600, 610, 620,

630, 640, 650, 660, 670, 680, 690, 700, 710, 720, 730, 740, 750, 760, 770, or about 780 nm. Although first region 102 is discussed as having a high percent transmission of light in the infrared range, it will be appreciated that first region 102 can have a percent transmission of light in the visible range that is substantially equal to that of second region 104.

[0023] First region 102 and second region 104 can account for any amount of the total surface area of glass laminate 100. For example, first region 102 can be in a range of from about 1 percent surface area to about 95 percent surface area of glass laminate 100, about 5 percent surface area to about 40 percent surface area, about 10 percent to about 25 percent, less than, equal to, or greater than about 1 percent surface area, 2, 3, 4, 5, 6, 7, 8, 9, 10, 1 1,

12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36,

37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61,

62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86,

87, 88, 89, 90, 91, 92, 93, 94, or about 95 percent surface area. Second region 104 can be in a range of from about 1 percent surface area to about 95 percent surface area of glass laminate 100, about 80 percent surface area to about 95 percent surface area, about 85 percent to about 90 percent, less than, equal to, or greater than about 1 percent surface area, 2, 3, 4, 5, 6, 7, 8,

9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31 , 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51 , 52, 53, 54, 55, 56, 57, 58,

59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83,

84, 85, 86, 87, 88, 89, 90, 91 , 92, 93, 94, or about 95 percent surface area.

[0024] FIG. 2 is a sectional view of glass laminate 100 taken along line A-A of FIG.

1. As shown in FIG. 2, glass laminate 100 includes first curved glass substrate 106, second curved glass substrate 108, and interlayer 110 disposed therebetween. Although curved glass substrates 106 and 108 are shown, in other embodiments either substrate 106 or 108 may be straight or substantially free of any curve. First curved glass substrate 106 includes first major surface 112 and second major surface 114 opposing first major surface 112. Second curved glass substrate 108 includes third major surface 1 16 and opposing fourth major surface 118. Interlayer 110 includes fifth major surface 120, which is adjacent to second major surface 114. Interlayer 1 10 further includes sixth major surface 122 opposed from fifth major surface 120 and adjacent to third major surface 1 16.

[0025] Glass laminate 100, can include a variety of different coatings or films attached to any of the surfaces described herein. For example, as shown in FIG. 2, film 124, which can help to reduce Fresnel loss on a surface, is applied to first major surface 112 and fourth major surface 118 in first region 102. In further embodiments, film 124 can be applied to any other surface of glass laminate 100, including in second region 104. Another example of a film or coating that can be applied to glass laminate 100 is a film or coating adapted to at least partially block infrared radiation. An example of such a film or coating is film 126, which is adapted to at least partially block solar radiation or solar near infrared radiation.

Film 126 can be applied to any other surface of glass laminate 100, but likely will not be located in second region 104 as this may reduce the percent of light in the infrared range that is able to be transmitted through second region 104. According to various embodiments, the films or coatings described herein can be adapted to form an image, which can be a picture or alphanumeric pattern. According to further embodiments, the film or coatings described herein can be an antireflective coating.

[0026] According to various embodiments, first curved glass substrate 106 and second curved glass substrate 108 can independently include soda lime silicate glass, alkali aluminosilicate glass, alkali containing borosilicate glass, alkali aluminophosphosilicate glass, alkali aluminoborosilicate glass, or a mixture thereof.

[0027] According to various embodiments of the present disclosure, the soda lime silicate glass can be a low iron soda lime silicate glass in that it is substantially free of iron, iron oxide, or mixtures thereof. In embodiments of any glass substrate including these low iron soda lime silicate glasses, the substrate may allow for a high percentage of infrared radiation to pass therethrough.

[0028] The thickness of first curved glass substrate 106 and second curved glass substrate 108 can independently be in a range of from about 0.3 mm to about 5 mm, about 0.5 mm to about 3 mm, less than, equal to, or greater than about 0.3 mm, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1 , 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1 , 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3,

3.1 , 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, or about 5 mm. According to various embodiments, the thickness of first curved glass substrate 106 and second curved glass substrate 108 can be substantially the same or different. [0029] In one or more embodiments, the outer ply has an outer ply thickness (t₀) and an inner ply has an inner ply thickness (ti) such that t₀/ti is in a range from 1 to 20, or from 3 to 20, or from 3 to 15, or from 4 to 10, and like ratios, including intermediate values and ranges.

[0030] According to various embodiments of the present disclosure, first curved glass substrate 106 and second curved glass substrate 108 can independently be unstrengthened, annealed, or strengthened. Where the first curved glass substrate 106 and/or second curved glass substrate 108 is a strengthened glass substrate, the strengthened glass substrate may be strengthened to include a compressive stress that extends from a surface to a depth of compression or depth of compressive stress layer (DOL). The compressive stress at the surface is referred to as the surface CS. The CS regions are balanced by a central portion exhibiting a tensile stress. At the DOL, the stress crosses from a compressive stress to a tensile stress. The compressive stress and the tensile stress are provided herein as absolute values.

[0031] In one or more embodiments, the strengthened glass substrate may be strengthened in two or more steps to achieve a first partially strength level (i.e., strengthened to a degree that is a portion of the final strength level in terms of surface CS and DOL) and a final strength level. In one or more embodiments, the strengthening process used to strengthen the strengthened glass substrate may include any one or combinations of a thermal strengthening process, a chemical strengthening process and a mechanical strengthening process.

[0032] In one or more embodiments, the strengthened glass substrate may be mechanically strengthened by utilizing a mismatch of the coefficient of thermal expansion between portions of the article to create a compressive stress region and a central region exhibiting a tensile stress. In some embodiments, the strengthened glass substrate may be thermally strengthened by heating the glass to a temperature above the glass transition point and then rapidly quenching.

[0033] In various embodiments of the present disclosure, the strengthened glass substrate may be chemically strengthened by ion exchange. In the ion exchange process, ions at or near the surface of the glass substrate are replaced by - or exchanged with - larger ions having the same valence or oxidation state. In embodiments in which the strengthened glass substrate comprises an alkali aluminosilicate glass, ions in the surface layer of the article and the larger ions are monovalent alkali metal cations, such as Li⁺, Na⁺, K⁺, Rb⁺, and Cs⁺. Alternatively, monovalent cations in the surface layer may be replaced with monovalent cations other than alkali metal cations, such as Ag⁺ or the like. In such embodiments, the monovalent ions (or cations) exchanged into the glass substrate generate a stress. It should be understood that any alkali metal oxide containing inner glass ply can be chemically strengthened by an ion exchange process.

[0034] According to various embodiments, a thickness of interlayer 110 is in a range of from about 0.30 mm to about 3 mm, about 0.38 mm to about 1.52 mm, less than, equal to, or greater than about 0.30 mm, 0.35, 0.38, 0.40, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70, 0.75, 0.80, 0.85, 0.90, 0.95, 1.00, 1.05, 1.10, 1.15, 1.20, 1.25, 1.30, 1.35, 1.40, 1.45, 1.50, 1.52, 1.55,

1.60, 1.65, 1.70, 1.75, 1.80, 1.85, 1.90, 1.95, 2.00, 2.05, 2.10, 2.15, 2.20, 2.25, 2.30, 2.35,

2.40, 2.45, 2.50, 2.52, 2.55, 2.60, 2.65, 2.70, 2.75, 2.80, 2.85, 2.90, 2.95, or about 3.00 mm.

Interlayer 110 can include any suitable material including a polycarbonate, polyvinyl butyral, acoustic polyvinyl butyral, an ionomer, ethylene-vinyl acetate, a thermoplastic polyurethane, a polyester, polyethylene terephthalate, a polyacrylate, polymethyl methacrylate, polycarbonate, a cyclic olefin polymer, a polyester, a polyurethane, co-polymers thereof, ethylene -vinyl acetate, or a mixture thereof.

[0035] As shown in FIG. 2, interlayer 110 includes a plurality of materials. The materials of interlayer 110 located in first region 102 include an infrared transparent material adapted to have a percent transmission of light, having a wavelength in a range of from about 800 nm to about 5 pm, in a range of from about 70 percent to about 100 percent, about 90 percent to about 99 percent, less than, equal to, or greater than about 70 percent, 71, 72, 73,

74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91 , 92, 93, 94, 95, 96, 97, 98, 99, or about 100 percent. According to various embodiments, the light can have a wavelength in a range of from about 850 nm to about 5000 nm, about 900 nm to about 1550 nm, less than, equal to, or greater than about 800 nm, 850 nm, 900 nm, 1000 nm, 1500 nm, 1550 nm, 2000 nm, 3000 nm, 4000 nm, 5000 nm, 1 pm, 2 pm, 3 pm, 4 pm, or about 5 pm. Examples of suitable infrared transparent materials include, a polyacrylate, polymethyl methacrylate, a polycarbonate, a cyclic olefin polymer, a polyester, a polyurethane, co-polymers thereof, ethylene -vinyl acetate, or mixtures thereof. The balance of interlayer 110, can include the same materials, but can also include materials that are not transparent to infrared radiation to the same degree. [0036] FIG. 3 is a sectional view of glass laminate 100A. Glass laminate 100A includes many of the same components as glass laminate 100. As shown in FIG. 3, however, glass laminate 100A includes infrared transparent material 130 located at first region 102 and disposed within first curved glass substrate 106. Infrared transparent material 130 can be any of the infrared transparent materials described herein or any mixture thereof. In the embodiment shown in FIG. 3, the portions of first curved glass substrate 106 that are located within second region 104 can include a glass material that is not transparent to infrared radiation such as soda lime silicate glass. Second curved glass substrate 108 can include a glass material that is substantially transparent to infrared radiation such as a soda lime silicate glass that is substantially free of iron, iron oxide, or mixtures thereof. Interlayer 110 can include any of the materials described herein. In embodiments where interlayer 110 includes polyvinyl butyral, glass laminate 100A may have a higher percentage of infrared radiation transmitted having a wavelength in a range of from about 900 nm to about 1000 nm than to infrared radiation transmitted having a wavelength of about 1550 nm.

[0037] FIG. 4 is a sectional view of glass laminate 100B. Glass laminate 100B includes many of the same components as glass laminate 100 and 100A. As shown in FIG. 4, however, glass laminate 100B includes infrared transparent material 130 located at first region 102 and disposed within first curved glass substrate 106 and interlayer 1 10. In the embodiment shown in FIG. 4, the portions of first curved glass substrate 106 that are located within second region 104 can include a glass material that is not transparent to infrared radiation such as soda lime silicate glass. Second curved glass substrate 108 can include a glass material that is substantially transparent to infrared radiation such as a soda lime silicate glass that is substantially free of iron, iron oxide, or mixtures thereof. Sections of interlayer 110 located at second region 104 can include any of the interlayer materials described herein. Because the section of interlayer 110 located at first region 102 includes infrared transparent material 130, infrared radiation of any wavelength can be transmitted therethrough.

[0038] First region 102 of any of glass laminates 100, 100A, or 100B described herein can be directly attached to, or in communication with a L1DAR system. As understood, L1DAR can refer to a remote sensing method that uses light in the form of a pulsed laser to measure ranges to the Earth. These light pulses generate precise, three- dimensional information about the shape of an object that it contacts and its surface characteristics. Examples of two types of L1DAR are topographic and bathymetric. Topographic L1DAR can use a near- infrared laser to map the land, while bathymetric L1DAR uses water-penetrating green light to also measure seafloor and riverbed elevations.

[0039] A L1DAR instrument can include a laser, a scanner, and a

specialized GPS receiver. Airplanes and helicopters are commonly used for acquiring L1DAR data over broad areas. However, it can also be desirable to include LIDAR in an automobile. In the context of an automobile, LIDAR can be useful for autonomous vehicles. This is because LIDAR can quickly and accurately map an environment surrounding the autonomous vehicle, which the vehicle can use to navigate.

[0040] Conventionally, LIDARs for autonomous vehicles are mounted on a roof-top.

This is because of the visibility afforded to the LIDAR. But, mounting the LIDAR units on the roof-top exposes it to damage and wear from the elements. For example, the LIDAR can be subjected to rock strikes and contamination from the environment. However, the ability of glass laminate 100, 100 A, and 100B to allow for a high percentage of infrared transmission to pass through it at first region 102 allows for the LIDAR to be moved inside the vehicle and placed in optical communication with first region 102. For example, in embodiments where glass laminate 100, 100A, or 100B are a windshield, the LIDAR can be placed in the interior of the vehicle and in contact, and/or in communication, with first region 102. According to various embodiments, first region 102 and LIDAR can be located proximate to a rearview mirror so that the LIDAR minimally impacts a driver’s field of vision. Reasons to locate the LIDAR in the interior of the vehicle include mitigating the risk of damage caused by the elements, if the LIDAR is placed outside of the vehicle. Furthermore, placing the LIDAR inside the vehicle can help to prevent LIDAR from affecting the aerodynamics and aesthetics of the vehicle. Furthermore, the ability to clean the windshield easily (e.g., with wipers) can help to ensure that the LIDAR has a clean field of vision. Although glass laminate 100, 100A, and 100B are described as a windshield, it can be any glass component of a vehicle including a rear window, side window, moonroof, or headlight cover.

[0041] Glass laminate 100, 100A, or 100B can be formed according to many suitable methods. For example, interlayer 110 can be formed to include at least one infrared transparent material 130. Interlayer 110 can then be contacted with second major surface 114 of first glass substrate 106 and third major surface 116 of second glass substrate. Interlayer 110 is then joined to the respective surfaces to form glass laminate 100.

[0042] Glass laminate 100A and 100B can be formed by contacting interlayer 110 with second major surface 114 of first glass substrate 106 and third major surface 116 of second glass substrate. Interlayer 110 is then joined to the respective surfaces. Unlike interlayer 110 of glass laminate 100, interlayer 110 of glass substrates 100A and 100B does not need to include infrared transparent material 130. However, in some embodiments, interlayer 110 can include infrared transparent material 130.

[0043] After interlayer 110 is joined to the respective surfaces, a void is formed. The void can extend through first glass substrate 106, interlayer 110, or both. If the void extends only through first glass substrate 106, glass laminate 100A will be formed. If the void extends through both first glass substrate 106 and interlayer 110, glass laminate 100B will be formed.

[0044] After the void is formed, infrared transparent material 130 is deposited in the void. Infrared transparent material 130 can be deposited in the void as a powder, which can then be fused to form the final infrared material 130. Infrared transparent material 130 can also be deposited in the void as a slurry, which can be cured or polymerized therein to form the final infrared transparent material 130. Alternatively, infrared transparent material 130 can deposited in the void through an additive manufacturing process.
