Jerrett Jern holds a HYpnos sleep mask that is a self-learning snore-reduction mask at the CES Unveiled event for media prefacing the tech mega-conference at Mandalay Bay in Las Vegas, Sunday, Jan. 6, 2019. Using Bluetooth technology, the mask connects to the HYpnos sleep analysis app that provides real-time data to help users identify the factors that contribute to snoring. It will cue the user to change positions by using gentle vibrations, so that with the movement the snoring will stop. If snoring continues, the HYpnos sleep mask will increase expiratory positive airway pressure, using your own breath to open airways so the snoring can subside.
