In a latest development in the field of Patent and Trademark, the United States Patent Office approved a new patent to tech giant Apple that will help device/devices expel droplets of liquid automatically using electrical energy. According to sources, the acoustic module present in the device will use pulse of energy to determine if there is any water and if so it will be expelled through the outlet by one of the electrodes. However, it is unlikely that this technology will be available to IPhone-6 versions of Apple and hence consumer will have to wait to use this clever idea that use sound and electricity to make iPhones more water resistant.
