US Patent 11947390 Eyewear device charging case

A case for an eyewear device includes a body defining an opening leading to a storage chamber that is sized for retaining the eyewear device. A cover depends from the body and is movable between an open position, in which the opening is exposed, and a closed position, in which the opening is covered by the cover. A battery is mounted to the body for charging the eyewear device. A detector is positioned on either the body or the cover for detecting when the cover is in the open position or the closed position. A display displays a charge state of the battery when the cover is in the open position.
