More advancements were made to washing machine technology in the form of the rotative drum design. These early design patents consisted of a drum washer that was hand-cranked to make the wooden drums rotate. While the technology was simple enough, it was a milestone in the history of washing machines, as it introduced the idea of "powered" washing drums.
Logitech 2.4 GHz Digital Cordless for Business features frequency agility. With this technology, the Logitech mouse or keyboard that encounters any interference from another cordless device will automatically identify and switch to a more “quiet” location in the band to transmit data.
Waterproof means that the device is not adversely affected by contact with water and can withstand water contact without becoming damaged.
