    Abstract: Implementations of various computer methods to couple a computerized ball device which acts as a mobile computing device to record the users environment and project light towards waveguide eyeglasses or contacts which then allows a user to view imbedded light structure holograms in the waveguide while viewing the actual world. The computer ball device additionally has the ability to be docked in a drone cradle which creates a database map of the user's environment while not being utilized by the user for an immediate task. The device may also attach to a wrist band for mobility. The device also has the ability to couple the projected light structures so that a plurality of users may view the same light structure content to build an environment of trust. The device decouples the traditional design of head mounted virtual and mixed reality that place together the camera with the head mounted device.

  • Patent number: 11159753
    Abstract: A high dynamic range image sensors enabled by integrating broadband optical filters with individual sensor pixels of a pixel array. The broadband optical filters are formed of engineered micro or nanostructures that exhibit large differences in transmittance, e.g. up to 5 to 7 orders of magnitude. Such high transmittance difference can be achieved by using a single layer of individually designed filters, which show varied transmittance as a result of the distinct absorption of various material and structures. The high transmittance difference can also be achieved by controlling the polarization of light and using polarization-sensitive structures as filters. With the presence of properly designed integrated nanostructures, broadband transmission spectrum with transmittance spanning several orders of magnitude can be achieved. This enables design and manufacturing of image sensors with high dynamic range which is crucial for applications including autonomous driving and surveillance.

In one aspect, one or more optical elements of an x-ray based system include an integrated optical filter including one or more material layers that absorb radiation having energy outside the desired energy band. In general, the integrated filter improves the optical performance of an x-ray based system by suppressing reflectivity within infrared (IR), visible (vis), ultraviolet (UV), extreme ultraviolet (EUV) portions of the spectrum, or any other undesired wavelength region. In a further aspect, one or more diffusion barrier layers prevent degradation of the integrated optical filter, prevent diffusion between the integrated optical filter and other material layers, or both. In some embodiments, the thickness of one or more material layers of an integrated optical filter vary over the spatial area of the filter.

  • Patent number: 11028471
    Abstract: A composition of AR layer that is aimed to match the refractive index of the underlying substrate e.g. glass, chemically strengthened glass, plastics etc., so as maximum light is transmitting through it. For a device with an sapphire film for anti-scratch protection, because sapphire has a different refractive index to that of the substrate, therefore existing AR layer will not function as well as it should; not only the transmitted light is reduced in quantity, its transmitted range will be changed such that imaging or display color is compromised. Therefore an integrated AR with sapphire film with the top most AR layer as Al2O3 which also acts as anti-scratching layer will eliminate this problem. This claim involves replacing one of the materials for AR layer is Al2O3 such that the top most AR layer as Al2O3 which also acts as anti-scratching layer.

  • Patent number: 11022733
    Abstract: An optical filter having a substrate including a primary bandpass filter at least predominantly on an interference basis and a secondary bandpass filter at least predominantly on an interference basis. Both bandpass filters are designed such that they transmit sufficiently over the entire required angle range in the desired spectral transmittance wavelength interval. The primary bandpass filter contains the small angle shift required by the overall system. It also has a spectral transmittance wavelength interval which is as small as possible according to the requirements of the respective application and restricted by narrow blocking bands. The secondary bandpass filter is designed such that its transmittance wavelength interval is limited by a short-wave edge and a long-wave edge and is adjusted to the primary bandpass filter in such a way that its edges shift over the required angle range only within the blocking bands of the primary bandpass filter.
