TODAY’S PATENT – SOLAR POWERED BIRD REPELLING DEVICE
The Solar powered bird repelling device was invented by Bruce Donoho on December 22, 1992 bearing patent number US9521838B2.
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. Birds sometimes cause harm to humans, gardens, patios, golf courses, warehouses, loading docks, poles, wires, trees, buildings, and various other animals and structures. Various devices exist that attempt to deter or repel certain insects or pests using ultrasonic sound waves, but existing devices suffer various limitations.
A photovoltaic cell or array is used to power a bird repelling device that emits deterrent sounds from a speaker or other sound emitter, under control of an electronic processor. Repellant sounds can be either a single sound, or a set of sounds, including for example pest species sounds and predator species sounds. One or more sensors, and a user interface, can assist in controlling which sound(s) to use, and when.
