  • Patent number: 10466505
    Abstract: A lens system comprises a first electro-active lens comprising a first focus sensor coupled to a first processor and a second electro-active lens comprising a second focus sensor coupled to a second processor. The first focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The second focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The first processor receives an indication of the second electromagnetic signals and, based on the received indication of the second electromagnetic signals, determines a relative convergence angle between the first and second electro-active lenses. Based on the determined relative convergence angle, the first processor determines a focal setting for the first electro-active lens and controls an electroactive element in the first electro-active lens, based on the determined focal setting.

  • Patent number: 10444491
    Abstract: A variable focal length optical assembly may include a deformable entry lens element, a deformable first reflective element and a deformable second reflective element. Using a controller coupled to the deformable elements, an external force such as a mechanical, electrical, electromechanical, or electromagnetic force is applied to the deformable elements to provide any number of different focal lengths. Since the deformation of the deformable elements, and consequently the changes in focal length, occur much faster than the playback frame rate, a number of sub-frames, each containing an image obtained at a different focal length, are associated with each playback frame. The availability of multiple images in the form of sub-frames permits the selection of an optimal image for inclusion in the final playback frame sequence. The availability of multiple images in the form of sub-frames at different focal lengths also permits the seamless incorporation of zoom-in and zoom-out effects.

  • Patent number: 10442774
    Abstract: Methods and systems are disclosed relating to a lens system that allows for simultaneous focus of near and far-away images with one pair of glasses, heads-up-displays (HUDs), and the like, without the need to move the user's eyes. This lens system may be used in a HUD application, for example, where the user may focus on a display lens that may be approximately one inch from the eye to view computer-generated information such as altitude, temperature, directions, and the like, and simultaneously view the individual's surroundings. The lens system may include a liquid lens that when modulated may vary from a near-focus state to a far-focus state rapidly by using an electrowetting or piezoelectric hydraulic actuator. This variable rate lens may be multiplexed at a rate that allows both near and far-away images to appear in focus simultaneously through the advantageous use of a user's persistence of vision.
