  • Patent number: 11002990
    Abstract: An eye-mountable device is provided that includes an eyelid occlusion sensor. The eyelid occlusion sensor is used to detect winks, squints, downwards glances or looks, blinks, or other eye-based gestures generated by the user. Based on the detected gestures, an optical power of an adjustable lens of the device may be changed or some other operations could be performed by the eye-mountable device. Such operations could include toggling the optical power of the lens between first and second power levels due to the user squinting, looking downward, or performing some other gesture. Additionally or alternatively, such operations could include setting the optical power of the lens to a first optical power unless the user is looking downward, in which case the optical power of the lens could be set to a second optical power.

  • Patent number: 11002953
    Abstract: A spatial light modulator (SLM) is disclosed, wherein the SLM has a substrate comprising an array of MEMS-based mirror elements that is periodic with small pitch (<3 microns) and high fill factor (>80%) in a first dimension. Each mirror element includes a micromirror whose height above the substrate is controlled via a vertical comb-drive actuator, which is located completely beneath the micromirror in the first dimension. As a result, mirror element can control the phase of light reflected from its micromirror. In some embodiments, the SLM includes an array of mirror elements that is periodic with small pitch and high fill factor in two dimensions. In such embodiments, the actuator, as well as tethers for supporting the micromirror above the substrate, are located completely beneath the micromirror, thereby enabling high fill factor in both dimensions.

  • Patent number: 10989919
    Abstract: A pad shape for a support assembly is optimized to provide universal fitting characteristics to Head-Mounted Display (HMD) devices. The pad shape enables a display of a single HMD device to be reliably aligned within multiple users' fields-of-view notwithstanding significant variations of shape and size between these users' heads. Optimal positioning of the display within the multiple users' fields-of-view may be achieved by positionally constraining the HMD device against a portion of the head that varies relatively slightly as compared to other portions of the head. The contact pad includes a curved region having a shape defined by a high order polynomial that corresponds to an empirically determined best fit surface. Empirically determining one or both of the best fit surface or the high order polynomial may include aligning a plurality of “forehead” point clouds that map the geometries of a sample set of users' foreheads.

  • Patent number: 10983321
    Abstract: A method for the examination of a sample includes illuminating the sample in a sample plane along a sample line with an illuminating light beam. The sample is acted upon by a depletion or switching light beam, which overlaps in the sample plane in an overlap region with the illuminating light beam. Part of fluorescent light emanating from the sample plane is detected as detection light originating from a first subregion of the overlap region, in which the probability of an interaction of the sample molecules with the depletion or switching light beam is greater than 90%, and/or originating from a second subregion which is at least partially surrounded by the first sub-region and/or in which the depletion or switching light beam has a zero point, while at the same time the fluorescent light originating from outside the first subregion and the second subregion is suppressed and not detected.

  • Patent number: 10976563
    Abstract: Provided is an optical unit and a display device capable of suppressing the occurrence of stray light by suppressing the incidence of light onto a peripheral region of a panel. In the optical unit, a first panel, a second panel, and a third panel are arranged to face a dichroic prism. A first light-emitting element is provided in a display region of the first panel, the second panel, and the third panel, and metal wiring is provided in a peripheral region. Here, a light shielding layer is provided between the dichroic prism and the peripheral region of each of the first panel, the second panel, and the third panel. Thus, even when a part of color light that should be reflected passes through a dichroic mirror, the leaked light is absorbed by the light shielding layer.
