Certain example embodiments of this invention relate to patterns that help deter birds from colliding with building facades and other transparent barriers, techniques for creating such patterns, articles including such patterns, and methods of making such articles. More particularly, certain example embodiments of this invention relate to making use of the difference in visually perceivable spectra as between humans and birds to create at least pseudo-random and generally non-repeating patterns that help deter birds from colliding with building facades and other transparent barriers, techniques for creating such patterns, articles including such patterns, and methods of making such articles.
Birds are incredibly agile, fly at high speeds, and are constantly interacting with the environment around them. Birds tend to be very aware of their body size and, thus, how small of an opening they can fit through.
Birds unfortunately sometimes come into contact with glass surfaces on building facades (including home windows, office buildings, etc.) and other transparent barriers. Birds that fly into windows at a high velocity can injure and sometimes even kill themselves as a result of the contact and/or a subsequent fall, or predation after landing with a collision injury. Interestingly, many birds that most often are victims of collisions have a near 360 degree field of view or spatial awareness but oftentimes have no or limited binocular vision. This suggests that, in flight, birds tend to look at their surrounding environment (e.g., for food or predators) rather than looking ahead at where they are going.
The sources of this problem can in some instances be linked to light reflection and light transmission complications, as well as the tendency to see in the manner described above. For instance, birds can mistake reflection on the surface of glass for extensions of the natural environment. Even low reflection glass can act like a mirror when it is bright outside and dark inside. In fact, when coupled with certain façade designs, reflections can create areas that are so visually confusing that the birds do not know how to escape (like a funhouse mirror maze).
In the context of reflection, for example, in applications where there is a direct line of sight from one window to another (such as might be the case with walkways, corner offices, bus stops, etc.), birds do not necessarily perceive the glass as a barrier and may attempt to fly through. In fact, in atriums with indoor plants, the space can seem to be an inviting habitat into which some birds will attempt to fly. And similar to the confusion caused by reflection that creates a funhouse effect, birds can often become trapped in glass enclosures that are similar to tunnels or the like, as there is no obvious difference to birds between open exits and glass.
Birds basically perceive a spectrum similar to that perceivable by humans in that, as a general rule of thumb, if something can be perceived by a human, it also can be perceived by a bird. However, birds also have some vision that extends into the ultraviolet range. The UV tends to be a weaker signal perceivable by some birds, but it nonetheless means that there are frequency ranges that are perceivable by some birds that are not also perceivable by humans.
Some current products that attempt to deter birds from colliding with building facades and other transparent barriers attempt to make use of the difference in perception between birds and humans. For instance, it is possible, at least in theory, to provide to a glass or other transparent substrate a thin film or other coating that is perceivable in the UV range and thus to birds that is not also perceivable by humans. In this regard, some current products provide patterns across the surface of the substrate. Such patterns typically are generally linear arrangements of lines or dots that are sized and spaced in accordance of best practices determined by avian researchers.
Unfortunately, however, such standard pattern designs oftentimes need to be carefully designed and aligned as they are being prepared for inclusion into a transparent article (such as, for example, an insulated glass or other window unit for a building, transparent barrier at a lookout, bus stop, and/or the like). This can impose design and manufacturing hurdles. For instance, some designs are largely ineffective for some orientations in that they can deter bird collisions if installed in a vertical but not horizontal manner. Generally, current grid-like designs make manufacturing challenging, as up to 50% of the yield can be lost if installed in a vertical orientation. Misalignments, misregistrations, and/or the like, also can create small gaps or areas that birds can fly into. It also would be desirable to increase the overall effectiveness of the patterns.
Certain example embodiments address the above-described and/or other issues. For instance, certain example embodiments help deter birds from colliding with building facades and other transparent barriers, e.g., by making use of the difference in visually perceivable spectra as between humans and birds. One aspect of certain example embodiments relates to providing patterns of design elements to transparent substrates that are effective in this regard. Another aspect of certain example embodiments relates to simplistic manufacturing and installation procedures, e.g., enabling patterns to be applied to substrates so that those substrates can be used in a variety of different orientations in a variety of different products without sacrificing effectiveness. Certain example embodiments advantageously enable cutting and sizing without regard for the pattern orientation. In other words, certain example embodiments advantageously are highly functional regardless of how the substrates are cut, sized, installed, etc.
The patterns of certain example embodiments may be produced according to a computer-implemented algorithm that creates an at least pseudo-random and generally non-repeating pattern in this regard. For instance, design rules may relate to position, rotation, and/or size randomness of the design elements included in the pattern. These features may work together to help create an average design element density that provides openings or areas where design elements are not larger than a given size (e.g., approximately 2″ by 2″ or 2″ by 4″ in size).
In certain example embodiments, a coated article is provided. A substrate supports a UV blocking coating on an exterior major surface thereof. The UV blocking coating is discontinuous and patterned to form a plurality of design elements, the design elements being positioned across the major surface of the substrate, and the design elements being sized, shaped, and arranged such that at least some design elements are oriented at angles that are neither normal nor substantially normal nor parallel nor substantially parallel to at least some of the other design elements, and such that openings between design elements in the UV blocking coating on average are no greater than a predetermined surface area.
In certain example embodiments, a method of making a coated article comprises: having a substrate; and forming a UV blocking coating on an exterior major surface thereof. The UV blocking coating is discontinuous and patterned to form a plurality of design elements, the design elements being positioned across the major surface of the substrate, and the design elements being sized, shaped, and arranged such that at least some design elements are oriented at angles that are neither normal nor substantially normal nor parallel nor substantially parallel to at least some of the other design elements, and such that openings between design elements in the UV blocking coating on average are no greater than a predetermined surface area.
A laminated product and/or insulating glass (IG) unit incorporating such a coated article, and methods of making the same, also are contemplated herein and also are provided by certain example embodiments.
Also contemplated herein, and also provided by certain example embodiments, is a method of making a pattern template for use in creating the pattern, the method comprising executing computer-programmed instructions to define the pattern and/or pattern template. Certain example embodiments, relate to a non-transitory computer readable storage medium storing instructions that, when executed, execute such a method. Similarly, certain example embodiments relate to a computing system comprising at least one processor and a memory, the memory storing such instructions that are executable to perform such a method.
The features, aspects, advantages, and example embodiments described herein may be combined to realize yet further embodiments.
These and other features and advantages may be better and more completely understood by reference to the following detailed description of exemplary illustrative embodiments in conjunction with the drawings, of which:
Certain example embodiments relate to making use of the difference in visually perceivable spectra as between humans and birds to create at least pseudo-random and generally non-repeating patterns that help deter birds from colliding with building facades and other transparent barriers, techniques for creating such patterns, articles including such patterns, and methods of making such articles. The patterns include design elements or areas of a UV-reflective material that is visible to birds and may or may not be easily perceivable to humans. For example, it is noted that the UV-reflective coating may reflect UV and also reflect at least some light that is visible to humans. In such situations, the color of the visible portion may be controlled for aesthetic and/or other purposes, while the UV reflective coating as a whole has an increased effectiveness in terms of deterring bird collisions. The patterns may be created in accordance with a plurality of design rules embodied in a computer-implemented algorithm. Execution of the algorithm defines the pattern. Once the pattern is defined, the transparent substrate can have the pattern applied thereto via any suitable manufacturing technique, e.g., as described in greater detail below.
Regarding the collision and other issues discussed above, it is believed that hummingbirds are one of the smallest highly-affected species of birds.
The patterns of certain example embodiments may include design elements located to provide for a suitable contrast perceivable to a bird. In this regard, a small dense pattern typically will be less visible from a distance or at speed, compared to a larger element larger density pattern even if the same percentage of surface area is covered. It also is noted that the same color might be visible on one background and not another. With respect to the former,
The patterns of certain example embodiments may be produced using any suitable manufacturing technique. In certain example embodiments, a pattern mask or template may be created and used to pattern a film or the like. Positive and negative type masks may be used in different example embodiments. For instance, ink masking, plate masking, die-cut film masking, photolithography, and/or the like, may be used. In certain example embodiments, a mask formed in accordance with a designed pattern may be applied over an article onto which the pattern is to be formed. Material in the form of ink, a thin film, and/or the like, may be added onto the article so as to create the design elements. That is, material in the form of an ink, thin film, or the like, may be provided through holes defined in the mask that correspond with the design elements placed in the pattern.
It will be appreciated that the three previous paragraphs help define the general solution space. In addition to some or all of these solution space considerations, some or all of the four following “top-level rules” may be imposed on the design. Configuration modifications to each top-level rule also are discussed.
Example Design Rule 1: All design elements in the pattern are to be the same. For example, the design elements may be a common geometry. The common geometry may be generally rectangular, generally circular, generally elliptical or the like. The individual elements all may have the same dimensions. For example, the length and width may be the same for each generally rectangular element, the radius may be the same for each generally circular element, the major and minor radii may be the same for each generally elliptical element, etc.
A user interface displayed on an electronic device such as a computer or the like may enable a user to impact how the pattern is formed. For instance, a first user interface element set may enable selection of the basic design element shape (e.g., rectangle, circle, ellipse, etc.). A second user interface element set may enable attributes of the selected shape to be modified. For instance, slider bars or the like may be used to control the length and width of rectangular elements, the radius of circular elements, etc. In certain example embodiments, randomness may be injected with respect to the size of the elements. For instance, size ranges may be specified using the second user interface elements, prompting the algorithm to provide individual elements within a specified size distribution. Although regular geometric patterns are described, modifications can be made thereto, e.g., to enable rounding of corners, gradients, replacement with other designs such as logos or the like, etc. A third user interface element set such as a series of checkboxes may enable or disable compositing similar to that described in connection with
Example Design Rule 2: Pattern elements are arrayed in random positions and rotations. Random positioning and rotation is apparent from
Example Design Rule 3: Pattern elements do not overlap. This can be seen in each of the
Example Design Rule 4: The negative space (packing) between pattern elements should satisfy a dimensionality requirement. For example, openings larger than a predetermined length and width or predetermined radius should not be permitted. The 2×4 or 2×2 rule may be employed in certain example embodiments. A user interface element may be provided so as to enable the user to adjust the density and/or change the dimensionality requirement. A slider bar may be used in this regard in certain example embodiments. It will be appreciated that his rule may be enforced within a tolerance in certain example embodiments. For instance, as can be seen in the upper-left corner of
Softer rules or guidance may be used to tune the algorithm in certain example embodiments. In this regard, in some instances, pattern design elements at or near one or more edges of the pattern might need or benefit from special treatment such as, for example, shortening while maintaining a square end. Doing so may help ensure Example Design Rule 4 is met, even though Example Design Rule 1 might be somewhat strained or compromised in limited areas. Several elements along the right edge of
Depending on the pattern size, edge elements may be repeated so as to cover a desired surface area of the transparent panel. This also may be necessary or desirable depending on the manufacturing method. For instance, if the design is adapted for use with a drum die cutter, the pattern may be made to seamlessly repeat along one axis.
It will be appreciated that grid-like patterns are avoided in certain example embodiments. For instance, certain example embodiments include at least some design elements that are oriented at angles that are neither normal nor substantially normal nor parallel nor substantially parallel to at least some of the other design elements. In this regard, substantially normal and substantially parallel means normal and parallel, respectively, within a threshold such as, for example, a threshold dictated by manufacturing tolerances or up to a given percentage such as, for example, 5%, 10%, 15%, or the like.
In general, the patterns shown in
It will be appreciated that the example techniques described herein may be used in connection with a variety of transparent panels and transparent panel types. This includes, for example, glass, plastic, and/or other substrates, used in monolithic, insulated glass (IG), vacuum insulated glass (VIG), laminated, and/or other products. These products may be used in a variety of applications such as, for example, windows in residential and commercial settings, architectural elements, greenhouses, and/or the like.
Although hummingbirds are mentioned, the techniques disclosed herein may be optimized for sizes and/or vision related to songbirds or passerines, or other flying birds or animals.
The terms “heat treatment” and “heat treating” as used herein mean heating the article to a temperature sufficient to achieve thermal tempering and/or heat strengthening of the glass inclusive article. This definition includes, for example, heating a coated article in an oven or furnace at a temperature of at least about 550 degrees C., more preferably at least about 580 degrees C., more preferably at least about 600 degrees C., more preferably at least about 620 degrees C., and most preferably at least about 650 degrees C. for a sufficient period to allow tempering and/or heat strengthening. This may be for at least about two minutes, or up to about 10 minutes, in certain example embodiments. These processes may be adapted to involve different times and/or temperatures.
As used herein, the terms “on,” “supported by,” and the like should not be interpreted to mean that two elements are directly adjacent to one another unless explicitly stated. In other words, a first layer may be said to be “on” or “supported by” a second layer, even if there are one or more layers therebetween.
