  • Patent number: 10758902
    Abstract: A semipermeable ultrathin polymer membrane comprises a substantially optically transparent polymer film having a surface area to thickness ratio of at least 1,000,000:1, and an array of precisely spatially ordered pores of a user-selected diameter defined therethrough. Such membranes can be fabricated by providing a mold having a patterned array of nanoholes femtosecond laser ablated in a surface thereof; applying a first polymer solution onto the mold surface so that the first polymer solution infiltrates the nanoholes; allowing the first polymer solution to dry and form a replica of the mold having a plurality of freestanding nanoneedles extending from a surface of the replica; removing the replica from the mold; coating the replica surface with a second polymer solution; drying the second polymer solution to form a porous polymer film; and dissolving the replica in a solvent to release the film from the replica as a semipermeable ultrathin polymer membrane.

  • Publication number: 20200225114
    Abstract: Techniques are described for inspecting optical devices, such as eyepieces, to determine whether they exhibit light leakage through an edge sealant that has been applied to the device. Embodiments provide an inspection apparatus that can be employed to detect the leakage of light through an edge sealant of an optical device, where the edge sealant is applied to prevent, or at least reduce, the leakage of light from the optical device. Light from a light source is projected into the optical device. The light can travel along one or more wave guides within the device, until reaching an edge of the device. Light that is able to leak through an edge sealant can be reflected, using mirror(s) in the apparatus, and detected by a camera. Image(s) captured by the camera can be analyzed to determine the performance of the optical device with respect to edge leakage.

  • Publication number: 20200220725
    Abstract: Disclosed is a system for authenticating a caller. The system assigns a public key and a private key to each Caller Identifications (CLID), of a plurality of CLIDs pertaining to a plurality of mobile telephony numbers. The system stores a plurality of CLIDs and a plurality of public keys, associated to the plurality of CLIDs, over a blockchain formed by the plurality of telephony service providers. The system sends a Multi Data Message Format (MDMF) message to a telephony service provider of a callee. The system analyzes the MDMF message to determine whether the CLID is present over the blockchain. The system enables the telephony service provider of the callee to retrieve a public key, of the plurality of public keys, corresponding to the CLID from the blockchain, when the CLID is present on the blockchain. The system authenticates the caller upon verifying the signature by using the public key.

  • Patent number: 10695961
    Abstract: A method for modifying the wettability of a surface of an object can comprise forming on the surface of the object one or more arrays of nanofibers, wherein the one or more arrays of nanofibers includes nanofibers spaced along an X-axis and a Y-axis at the same or different intervals along either axis, the one or more arrays of nanofibers is integral with the object, and the nanofibers all have a base portion that is substantially normal to the surface. The intervals, diameter, and length of the nanofibers of the one or more arrays of nanofibers are selected so that the wettability of the surface for one or more predetermined liquids is increased or decreased relative to the wettability of the surface in the absence of the array of nanofibers.

  • Patent number: 10698215
    Abstract: Methods and systems are disclosed for presenting virtual objects on a limited number of depth planes using, e.g., an augmented reality display system. A farthest one of the depth planes is within a mismatch tolerance of optical infinity. The display system may switch the depth plane on which content is actively displayed, so that the content is displayed on the depth plane on which a user is fixating. The impact of errors in fixation tracking is addressed using partially overlapping depth planes. A fixation depth at which a user is fixating is determined and the display system determines whether to adjust selection of a selected depth plane at which a virtual object is presented. The determination may be based on whether the fixation depth falls within a depth overlap region of adjacent depth planes. The display system may switch the active depth plane depending upon whether the fixation depth falls outside the overlap region.

  • Patent number: 10678055
    Abstract: A method and system for increasing dynamic digitized wavefront resolution, i.e., the density of output beamlets, can include receiving a single collimated source light beam and producing multiple output beamlets spatially offset when out-coupled from a waveguide. The multiple output beamlets can be obtained by offsetting and replicating a collimated source light beam. Alternatively, the multiple output beamlets can be obtained by using a collimated incoming source light beam having multiple input beams with different wavelengths in the vicinity of the nominal wavelength of a particular color. The collimated incoming source light beam can be in-coupled into the eyepiece designed for the nominal wavelength. The input beams with multiple wavelengths take different paths when they undergo total internal reflection in the waveguide, which produces multiple output beamlets.
