  • Publication number: 20190212518
    Abstract: A method and system are disclosed for using circular symmetry to eliminate the angle limitations of an optical axis in a scanned aperture holography system. A Room-sized Holography System may be a scanned aperture holographic video display and may comprise a rotating platform, a telescope comprising a first lens and a second lens, and scanners at the Fourier plane where the focal length of the first lens and the second lens meet. The platform may rotate around an axis aligned with a spatial light modulator. When the platform rotates, the scanners rotate, thereby de-rotating a SAW image. The second lens may be a spherical reflective surface for redirecting light from the spatial light modulator, having passed through the first lens and reflected off a mirror-scanner, toward a user's eyes. The user may be on a chair above the spatial light modulator, wherein the chair is configured to rotate with the spatial light modulator.

  • Patent number: 10346568
    Abstract: A method for collaborative finite analysis may include obtaining an electronic model of an engineering object, assigning users one or more geometries for pre-analysis editing to provide assigned geometries for each user, and enabling each user to conduct pre-analysis editing of their assigned geometries concurrent with other users. The method may also include conducting finite analysis on the assigned geometries of a first user concurrent with conducting finite analysis on the assigned geometries of a second user. Examples of pre-analysis editing include removing features that are secondary to analysis, applying a material definition to a geometry, pre-meshing a geometry, initiating automated meshing of a geometry, validating automated meshing of a geometry, editing a mesh for a geometry, manually meshing a geometry, defining one or more loads associated with a geometry, and defining one or more boundary conditions for a geometry. A corresponding system and apparatus are also disclosed herein.

  • Publication number: 20190113887
    Abstract: A method and system for recycling signals in a leaky mode device for a holographic display or other application. A leaky mode device comprises at least a first transducer, a substrate, and a second transducer. The first transducer may be configured to receive an input signal from a signal arbiter, which forwards to the first transducer as an input signal either a new input signal or a recycled input signal (or some combination of the two). The first transducer converts the received input signal to a SAW (surface acoustic wave) and transmits the SAW through the substrate to the second transducer, which converts the received SAW to an output signal, and forwards the output signal to an amplifier, which amplifies the output signal (now a “recycled” signal) and forwards to the signal arbiter. This system facilitates persistence for points in a holographic display without the need for continually rewriting to leaky mode devices.

  • Patent number: 10249086
    Abstract: Techniques of refining a model of a complex surface can include deriving a set of refinement rules based on eigen polyhedra in a plane. Such rules reduce the refinement of a mesh in the plane to a scale and translation of the eigen polyhedron. Such refinement rules may then be applied to a non-uniform mesh in three-dimensional space having an extraordinary point in place of conventional refinement rules used in Catmull-Clark surfaces or NURBS surfaces. When these refinement rules are applied to a non-uniform mesh having an extraordinary point, the limiting surface is G1 at the extraordinary point, i.e., the tangent surfaces of the limiting mesh are continuous at the extraordinary point.

    Abstract: According to an aspect, a device may include a deployable rolling joint having a first deployable joint member, a second deployable joint member, and a plurality of flexures coupled to the first deployable joint member and the second deployable joint member. The deployable rolling joint may move from an undeployed state to a deployed state in which the first deployable joint member forms a convex surface portion and the second deployable joint member forms a convex surface portion. When the deployable rolling joint is in the deployed state, the convex surface portion of the first deployable joint member may roll with respect the convex surface portion of the second deployable joint member, and the plurality of flexures may hold the first deployable joint member and the second deployable joint member together as the first deployable joint member and the second deployable joint member roll across each other.

  • Patent number: 10214410
    Abstract: Fluid level measurements for the shared tank and outflow information provided by calibrated flow meters corresponding to dispensing stations connected to the shared tank may be used to derive a filled volume model for the tank as a function of fluid level. Subsequently, a filled volume change for a shared tank over a selected time interval may be determined from pre-change and post-change fluid level measurements. The change in filled volume may be compared with the total fluid flow over the selected time interval as indicated by the flow meters of active dispensing stations. If the filled volume change for the tank is substantially different than the total fluid flow indicated by the flow meters, the flow meters may be collectively adjusted to provide a more accurate indication of the filled volume change in the shared tank.
