  • Patent number: 12253782
    Abstract: Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

  • Publication number: 20250060648
    Abstract: Concentric ring electrodes in a conventional electro-active lens are arranged in the same layer and spaced apart from each other to prevent electrical shorts. The spacing between electrodes depends on the substrate material and how the electrodes are made. Ideally, the electrodes should be as close together as possible to prevent eddies or discontinuities in the electric field that the electrodes apply to the electro-active material in the electro-active lens. These eddies or discontinuities degrade the electro-active lens's optical quality. Unfortunately, current photolithographic patterning processes cannot produce gaps smaller than about 5 microns on plastic substrates. To compensate for this constraint, the electrodes can be arranged on the substrate in two or more staggered layers, with the electrodes in one layer appearing to fill the gaps in the other layer(s) when looking through the electro-active lens.

  • Patent number: 12222511
    Abstract: A conventional head-mounted display (HMDs) can display a virtual image at a fixed focus (e.g., infinite focus). If the user looks at an object that appears closer than the virtual image, then accommodation by the user's eyes will cause the virtual image to appear blurry. The HMDs disclosed herein include a dynamic electro-active focusing element that changes the focus of the virtual image to account for accommodation by the user. This dynamic electro-active focusing element may include a curved layer of electro-active material, such as nematic or bi-stable (e.g., cholesteric) liquid crystal, disposed between a static concave mirror and a convex surface on a beam splitter or other optical element. Changing the refractive index of the electro-active material causes the focus of the dynamic electro-active focusing element, making it possible to shift the virtual image's focus in as the user's eyes change focus.

  • Publication number: 20240419018
    Abstract: An electro-active lens provides simultaneous focusing at two different optical powers. It does this with a stack of electro-active lens elements aligned along the same optical axis that each focus light in different polarization states (e.g., horizontal and vertical polarization states). If a first and second electro-active lens elements have different optical powers, light in a first polarization state can be focused to one optical power and light in a second polarization state can be focused to a different optical power simultaneously. The electro-active lens can be switched between different single and multiple optical powers. People with presbyopia may use the electro-active lens mounted in eyewear in place of conventional bifocal glasses. The electro-active lens may also be used in a scope to improve target aiming.

  • Patent number: 12153285
    Abstract: An ophthalmic device includes a lens and an electronic component embedded in the lens to enhance the functionality of the lens. The ophthalmic device includes a first coil to wirelessly receive energy from an external device, such as a wireless charger, and wirelessly transmits the received energy to a second coil coupled to the electronic component so as to power the electronic component. The first coil can function as part of a repeater to facilitate the wireless charging. The repeater can receive electrical energy wirelessly and works with various positions, sizes, and shapes of the electronic component. The wireless power efficiency can also be increased using the repeater to concentrate a magnetic flux within the second coil.

  • Publication number: 20240219807
    Abstract: A beam steering device includes a substrate with a first refractive index that defines a cavity, an electroactive material in the cavity that has a variable refractive index, and two sets of opposing overlays. The overlays in one set of opposing overlays are parallel to each other, while the overlays in the other set are tilted with respect to each other. This allows one or more electric fields between the overlays to be used to align the electroactive material in two different directions to change its refractive index, allowing for a faster speed of beam steering through refraction than conventional approaches.

  • Patent number: 11994784
    Abstract: Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities.
