Apple has won a patent related to detecting water damage in a gadget.
The patent, 8,210,032, describes a method by which customer service representatives can quickly determine if a product has been damaged by water. In order for the invention to work, Apple says that a detector would be placed inside an enclosed device and provide "at least one visual indication after being immersed in water." The detector, Apple says, is strategically placed within the enclosed device so users can determine water damage from the outside.
Apple filed for the patent in January 2010. However, the company has been including its Liquid Contact Indicator in products for years, dating back to the original iPhone. Upon being immersed in water, the indicator turns red, giving Apple employees conclusive evidence that it was wet.
