BIRD COLLISION-AVERTING WINDOW PANES
FIELD OF THE INVENTION
[00011 This invention relates to glass. In particular, the invention relates to bird collision-averting window panes that reduce the incidence of birds flying into a window.
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
[00011 This invention relates to glass. In particular, the invention relates to bird collision-averting window panes that reduce the incidence of birds flying into a window.
BACKGROUND OF THE INVENTION
[0002] Birds flying into window panes, particularly into windows in high rise structures which often make up the greater part of the surface of the walls in a high rise structure, is a significant ecological problem. Particularly in the case of migratory birds, during peak migration periods the number of bird fatalities from striking window panes is staggering. Some sources estimate that in the United States alone over one billion birds die each year from flying into windows.
[00031 The bulk of window collisions occur for two primary reasons. In daylight when the outdoor ambient light is bright, birds crash into windows when they see the reflection of a landscape off of the window, or when they see plants or other natural vegetation through the window. The second reason occurs at night when windows are illuminated from inside a structure, which for reasons that are not entirely clear seems to attract nocturnal migrant species and divert them from their intended flight path.
[00041 There are many sources of information and suggestions on how to prevent birds from hitting windows. Some solutions involve substantially eliminating the illumination of a window by such actions as turning out interior lights or closing blinds or other window coverings at night. Turning out lights is not practical where there are persons in the premises at night, and further relies on individuals to remember to take such steps, as does closing window coverings. Outdoor coverings such as bird exclusion netting are not practical for use on high rise buildings due to wind and installation issues.
Other solutions involve imprinting or forming the window with a material having an opaque or translucent pattern, which a bird processes as an obstruction, but applying a permanent pattern to the glass itself reduces visibility through the window to humans and occludes outdoor light coming into the structure, even at times when bird collisions are unlikely.
[0005] It would accordingly be advantageous to provide a means of encouraging birds to avoid flying toward window panes that does not require human intervention in order to be effective and does not substantially obscure the view through the window or occlude light shining into the premises.

DETAILED DESCRIPTION OF THE INVENTION
[0014] According to the invention, in order to avert bird collisions a window pane 10 is coated, filmed or laminated with at least one layer containing an optical brightener.
[0015] Optical brighteners, also known as "fluorescent whitening agents,"
are used to "whiten" or "brighten" the appearance of such materials as clothing fibers, plastics,
-3 -paints, inks and other materials where a white colour is considered to be aesthetically relevant or important. An optical brightener is a fluorescing compound which fluoresces by absorbing light in the ultraviolet (UV) portion of the electromagnetic radiation (EMR) spectrum, for example typically within the range generally between 300 and 400 nanometers, and emitting light in visible EMR wavelengths, generally within the visible blue portion of the spectrum between 400 and 500 nanometers.
100161 As used herein the term "optical brightener" means a compound that, either alone or in solution, fluoresces by absorbing ultraviolet light and emitting EMR of a lower wavelength, typically in the visible light portion of the EMR spectrum.
An optical brightener, such as (by way of non-limiting example only) 2,2'-(1,2-ethenediy1)bis(4,1-phenylene)bisbenzoxazole, may be mixed into a resin in the liquid phase, or into certain types of plastics in the liquid phase, to produce an optical brightening layer that can be applied to a pane of glass to avert bird collisions, for example in the manners described below.
Optical brightening laminate layer [0017] Figures 1 and 2 illustrates a first embodiment of a window pane 10 comprising an optical brightening laminate layer 16 disposed between two glass panes 12, 14. The laminate layer may be formed from a plastic film such as (without limitation) polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) that has been doped during manufacture with a suitable amount of an optical brightener. In this embodiment the doped laminate may be applied to the glass in conventional fashion, for example by interposing the optical brightening laminate layer 16 between the glass panes 12, 14 and applying heat and pressure to adhere the laminate layer 16 to the glass panes 12, 14 and form an integrated double-glazed window pane 10.
[0018] In a further laminated embodiment, illustrated in Figures 3 and 4, a double-glazed window pane 20 is produced with an optical brightening laminate layer between the two panes of glass 12, 14 formed from a liquid laminate, such as (without limitation) polyester (PE) or polyurethane (PUR) doped with an optical brightener. This can be constructed, for example, by applying a 1/16 inch silicon-based double-sided

The laminate layer may be formed from a plastic film such as (without limitation) polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) that has been doped during manufacture with a suitable amount of an optical brightener. In this embodiment the doped laminate may be applied to the glass in conventional fashion, for example by interposing the optical brightening laminate layer 16 between the glass panes 12, 14 and applying heat and pressure to adhere the laminate layer 16 to the glass panes 12, 14 and form an integrated double-glazed window pane 10.
[0018] In a further laminated embodiment, illustrated in Figures 3 and 4, a double-glazed window pane 20 is produced with an optical brightening laminate layer between the two panes of glass 12, 14 formed from a liquid laminate, such as (without limitation) polyester (PE) or polyurethane (PUR) doped with an optical brightener. This can be constructed, for example, by applying a 1/16 inch silicon-based double-sided
- 4 -adhesion tape 24 around the periphery of one glass pane 14, as shown in Figure 3, and adhering the second glass pane 12 to the tape 24. The void between the two panes 12, 14 is filled with the doped resin 22, which intrudes into the air gap between the panes 12, 14 by capillary action. Once the resin 22 has cured, the collision-averting window pane 10 is ready to be installed.
[0019] In this embodiment the base resin is doped with an optical whitener by mixing the optical whitener (which may for example be in powder form) into the resin in a desired proportion, for example 2g per 1000cc resin. This may vary depending upon the type of optical brightener, the type of resin and the desired degree of fluorescence.
[0020] Many species of birds are sensitive to wavelengths in the ultraviolet portion of the EMR spectrum, which is believed to be involved in mate selection, territorial displays and foraging for food. It is not clear whether it is the absorption of UV
wavelengths or the emission of visible wavelengths by the doped resin layer 20 that makes the window pane 10 look unusual to a bird, however it has been found that the construction of a window pane with the doped resin layer 20 has the effect of averting a substantial number of bird collisions. In tests, the laminated embodiment of Figures 3 and 4 scored 82 to 86 aversions per 100 potential collisions.
Optical brightening films and coatings [0021] Further embodiments of a bird collision averting window pane 30 are illustrated in Figures 5 to 7. In these embodiments a single glass pane 32 is coated with a doped optical brightening film layer 34 or with a sputtered or possibly pyrolytic optical brightening coating.
[0022] The doped film layer 34 may for example (without limitation) comprise conventional window film such as polyester (PE), polyethylene terephthalate (PET) or any other film capable of being doped with a suitable amount of fluorescent brightener and adhered to a glass pane 32. This embodiment is particularly suitable for retrofitting the doped film layer 34 to an existing window pane, for example by conventional window application adhesives and methods.

-5 -[0023] The film layer 34 containing the optical brightener need not be homogenous. It is also possible to apply a shape or pattern utilizing for example the film illustrated in Figures 5 to 7. Optical brighteners have such a minimal effect on transparency of the window pane in the visible wavelengths that it would ordinarily be unnecessarily complicated and costly to apply an optical brightening layer 34 in the shape of a pattern.
However, it may in certain circumstances be advantageous to utilize a pattern or shape, for example the silhouette of a predator bird species that may appear to a bird as a hazard rather than merely an obstruction.
[0024] Combinations of the embodiments described above are also possible.
This allows for the creation of multiple optical brightening layers and as such would provide the opportunity to use different optical brighteners in a single window pane.
[0025] It may also be possible to 'hard-coat' a glass pane with an optical brightener to achieve the desired collision-aversion effect. For example, a coating material doped with an optical brightener may be applied to the surface of glass in a molten state, typically during manufacture of the pane, known as -pyrolytic" coating.
[0026] Alternatively, a doped solution may be applied to a glass pane 32 in the solid state by conventional sputtering techniques, for example by chemical vapour deposition or plasma vapour deposition in an arc coating reactor. In this embodiment it may be possible to apply the optical brightening layer 34 at the same time as a low-e' layer, commonly used in windows for high rise buildings, in which a metal oxide layer may be applied to the glass by various methods including magnetron sputtering.
t00271 Experimentation with processed glass panes, for example sandblasted glass, anti-reflective glass etc. may yield improved collision-aversion results.
