  • Liquid lenses with shock protection
    Patent number: 11675182
    Abstract: A method of operating a liquid lens can include positioning a variable interface between first and second liquids in a brace position in response to a brace trigger event. The variable interface can be adjustable between (a) a rest position in which a perimeter of the variable interface is spaced from a first window of the liquid lens by a rest distance and (b) the brace position in which the perimeter of the variable interface is spaced from the first window by a brace distance. The brace distance can be greater than the rest distance. In the rest position, the variable interface can have a rest surface area. In the brace position, the variable interface can have a brace surface area. The brace surface area can be less than the rest surface area.

  • LIQUID LENSES
    Publication number: 20220057546
    Abstract: A liquid lens can include a first substrate with an interior recess. A second substrate with a bore can be bonded to the first substrate, whereby the interior recess of the first substrate and the bore of the second substrate cooperatively define at least a portion of a cavity of the liquid lens. A first liquid and a second liquid can be disposed in the cavity. A variable interface can be disposed between the first liquid and the second liquid, thereby forming a variable lens. The interior recess of the first substrate can be positioned outside of a sidewall projection of a sidewall surface of the cavity through the first substrate.
