This invention relates to a rotating heliograph with arched convex reflective mirror surfaces that provides an autonomous continuous flashing visual signal from the reflection of the Sun, that can be used for many applications such as a survival distress signal, drone (UAV) anti-collision/tracking, and as a bird deterrent.

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. The patterns may be created in accordance with a plurality of design rules embodied in a computer-implemented algorithm. Design rules relate to position, rotation, and/or size randomness of the design elements included in the pattern. 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.

A window is designed to prevent or reduce bird collisions therewith. In certain example embodiments, the window may be an insulating glass (IG) window unit, or alternatively a monolithic window. In IG window unit embodiments, the IG window unit includes first and second substrates (e.g., glass substrates) spaced apart from one another, wherein at least one of the substrates supports both a patterned ultraviolet (UV) absorbing coating for absorbing UV radiation, and a UV reflecting coating for reflecting UV radiation, so that a more contrasting UV image is emitted/seen and birds are capable of more easily seeing the window and avoiding collisions therewith. By making the window more visible to birds, bird collisions therewith and bird deaths can be reduced.

A cephalopod rearing cage capable of maintaining a cephalopod alive, wherein at least a portion of the cephalopod rearing cage is constituted by using a mesh sheet of not less than 4 mesh. Also provided is a cephalopod escape prevention sheet capable of maintaining a cephalopod alive, wherein at least a portion of the cephalopod escape prevention sheet is constituted by using a mesh sheet of not less than 4 mesh.

This invention relates to an insulating glass (IG) window unit designed to prevent or reduce bird collisions therewith. The IG window unit includes at least first, second and third substrates (e.g., glass substrates). At least one of the substrates supports an ultraviolet (UV) reflecting coating for reflecting UV radiation so that birds are capable of more easily seeing the window, and wherein at least two of the substrates are laminated to one another via a polymer-based laminating film (e.g., of or including PVB, EVA, or SGP) that may have a high UV absoprtion. The UV reflecting coating is preferably patterned so that it is not provided across the entirety of the IG window unit. By making the window more visible to birds, bird collisions and bird deaths can be reduced. The provision of the laminated substrates in the IG window unit is particularly advantageous for bird collision windows, because it can further reduce bird collisions by providing an increased contrast ratio, improve durability, and improve processing.
