  • Patent number: 10851914
    Abstract: A strained bilayer film with reinforcing members is used to open and close gas flow outlets in a microvalve array. The bottom layer of the bilayer film is compressive and the top layer is tensile. Reinforcing members are made from compressive material that accomplishes the dual objectives of reducing potential defects at the interface between the anchor region and the free region of the actuator, and controlling the stresses along the edges of the strained bilayer to avoid curling as the actuator unrolls from its normal coiled configuration in response to an applied voltage. Because of the configuration, the strained bilayer film occupies a minimal amount of space compared to other systems when the valve is opened, and it permits a higher density of microvalves to be utilized. Optional supports are provided over gas flow channel openings to increase the area over which the voltage is applied, increasing electrostatic stability of the actuators in maintaining their unrolled state for a variety of uses.

    Abstract: A method is provided for measuring or estimating stress distributions on heart valve leaflets by obtaining three-dimensional images of the heart valve leaflets, segmenting the heart valve leaflets in the three-dimensional images by capturing locally varying thicknesses of the heart valve leaflets in three-dimensional image data to generate an image-derived patient-specific model of the heart valve leaflets, and applying the image-derived patient-specific model of the heart valve leaflets to a finite element analysis (FEA) algorithm to estimate stresses on the heart valve leaflets. The images of the heart valve leaflets may be obtained using real-time 3D transesophageal echocardiography (rt-3DTEE). Volumetric images of the mitral valve at mid-systole may be analyzed by user-initialized segmentation and 3D deformable modeling with continuous medial representation to obtain, a compact representation of shape.

  • Patent number: 10609362
    Abstract: The present invention is an improvement in dynamic autostereoscopic visual displays emitting a field of light beams into an observer viewing space from a hogel array formed at a transparent projection screen surface having refractive beam expanding functions. The transparent screen is illuminated from the rear by an X-Y array of projectors focused on the screen, where each hogel location is illuminated by a local group of multiple projectors within the larger array. The brightness, color and direction of the light beams emitted by each hogel are controlled by one image point in each member of the local projector group that illuminates that hogel. The invention enables autostereoscopic display systems with compact dimensions and high overall resolution and brightness by combining the output of an array of small projectors with lower resolution and brightness on a single projection screen.

  • Patent number: 8797382
    Abstract: Various embodiments of the present invention are directed to negative refractive index-based holograms that can be electronically controlled and dynamically reconfigured to generate one or more color three-dimensional holographic images. In one aspect, a hologram comprises a phase-control layer having a plurality of phase modulation elements. The phase-modulation elements are configured with a negative effective refractive index and selectively transmit wavelengths associated with one of three primary color wavelength. The hologram also includes an intensity-control layer including a plurality of intensity-control elements. One or more color three-dimensional images can be produced by electronically addressing the phase-modulation elements and intensity-control elements in order to phase shift and control the intensity of light transmitted through the hologram. A method for generating a color holographic image using the hologram is also provided, as is a system for generating a color holographic image.

  • Publication number: 20140198364
    Abstract: A three-dimensional imaging system based on a stereo hologram is disclosed. Images composed of sub-images having the same vertical-horizontal resolutions which are generated at plural image projection modules having a two-dimensional arrangement structure are projected to a prism array plate or a transmission-type diffusion plate, and are converted into light points, i.e., image points through a microlens array unit. A diffusion plate used as an image display screen is mounted to a position at which images diffused from the light points intersect with images diffused from the adjacent light points.

  • Patent number: 8704822
    Abstract: A volumetric display system which enables user interaction is described. In an embodiment, the system consists of a volumetric display and an optical system. The volumetric display creates a 3D light field of an object to be displayed and the optical system creates a copy of the 3D light field in a position away from the volumetric display and where a user can interact with the image of the object displayed. In an embodiment, the optical system involves a pair of parabolic mirror portions.

  • Patent number: 8581965
    Abstract: A means for 3D imaging takes two plane pictures of an object in different angles and respectively projects the correspondent images of the object toward users' eyes. Accordingly, the visual data would be transmitted to user's brain and integrated to construct a solid vision. A facility for 3D imaging comprises a multiple image projector consisting of a displaying unit installed on a refracting unit. Wherein, the displaying unit performs a plurality of images, and the refracting unit adopts an optical unit. Thereby, image beams generated by the displaying unit would travel through the refracting unit and deflect by a certain angle. Accordingly, the images shot from two different angles would be respectively projected into user's eyes, and a solid vision could be constructed.

  • Patent number: 8564865
    Abstract: Hologram production techniques can combine source data representing realistic information describing an environment with source data providing representational information describing a feature of the environment and/or some object interacting with the environment. The combined data is used to produce holograms, and particularly holographic stereograms including features that enhance the visualization of the environment depicted in hologram. A haptic interface can be used in conjunction with such holograms to further aid use of the hologram, and to provide an interface to secondary information provided by a computer and related to the images depicted in the hologram.

  • Publication number: 20130250382
    Abstract: We fabricate a stereoscopic hologram of an object by capturing a sequence of 2D images of the object, moving camera along a linear axis past the object and keeping the optical axis of the camera perpendicular at each of the positions. The camera lens and image recording surface are translated along the axis such that a fiducial part of the image does not move. The sequence is replayed and a first volume hologram is recorded by recording holograms of the captured images on a diffusing screen in different spatial locations on a surface of the first volume hologram. This is then replayed to form a stereoscopic image of the object and a second, volume reflection hologram of the replayed image is recorded to provide the stereoscopic hologram. A central image of the sequence is aligned to the fiducial part of the holographic image to make the resulting hologram “user-friendly”.
