Abstract: A luggage article may include a plurality of walls together defining an outer structure of the luggage article, a wheel bracket attached to and extending from one of the walls, and one or more wheels attached to the wheel bracket. The wheel bracket may comprise a leaf spring having a loop-shaped profile and the one or more wheels may be rotationally attached to a lower end of the loop-shaped leaf spring. The configuration of the wheel bracket may result in higher shock absorption and reduced wheel noise comparative to conventional wheel brackets, and offer an improvement and alternative to conventional luggage wheel brackets.

Abstract: From only a single two-dimensional source image (20) of a scene, multiple images (28) of the scene are generated, wherein each image is from a different viewing direction or angle. For each of the multiple images, a disparity is generated corresponding to the viewing direction and combined with significant pixels (e.g., edge detected pixels) in the source image. The disparity may be filtered (26) (e.g., low-pass filtered) prior to combined with the significant pixels. The multiple images are combined into an integrated image for display, for example, on an auto stereoscopic monitor (10). The process can be repeated on multiple related source images to create a video sequence.

Abstract: Fast processing of information represented in digital holograms is provided to facilitate generating a hologram for displaying three-dimensional (3-D) holographic images representative of a 3-D object scene on a display device. A holographic generator component (HGC) can receive or generate visual images, comprising depth and parallax information, of a 3-D object scene. A hologram processor component can apply a first non-uniform transform to a visual image to generate a first signal, and can apply a second transform to the first signal to generate a second signal that corresponds to a hologram that represents the 3-D object scene. The hologram can be illuminated with a light beam to facilitate generating a holographic image(s) that can be a reconstructed image that reconstructs the 3-D object scene. A display component can display the holographic image(s) for viewing by an observer.

Abstract: Fast processing of information represented in digital holograms is provided to facilitate converting a complex Fresnel hologram into a phase-only hologram, which can be a localized error diffusion and redistribution (LERDR) hologram, for displaying 3-D holographic images representative of a 3-D object scene. For a complex Fresnel hologram representing a 3-D object scene, a holographic generator component (HGC) can directly apply an LERDR process to the complex hologram to facilitate converting the complex hologram into an LERDR hologram. As part of the LERDR process, the HGC can partition the complex hologram into segments, convert the complex values of the pixels in each segment to phase-only values, and apply error diffusion to each segment to facilitate generating the phase-only hologram. The HGC can apply error redistribution to the last pixel of each segment to produce the resulting LERDR hologram, which can be displayed on a phase-only display device.

Abstract: Cryptographic techniques for encrypting images, and decrypting and reconstructing images, are provided to facilitate preventing unauthorized access to images. A holographic cryptographic component (HCC) generates complex holograms of multi-dimensional source images of a multi-dimensional object scene. The HCC generates phase holograms, based on the complex holograms, using a stochastic hologram generation process, and encrypts the phase holograms to generate encrypted holograms based on a random phase mask, which can be the private encryption key. At the decoding end, an HCC overlays a conjugate phase mask on the encrypted holograms to decrypt them, wherein the decrypted holograms are illuminated with a coherent light source to generate holographic images that reconstruct the source images. The source images are only reconstructed properly if the correct phase mask is used. If HCC applies the encryption process repetitively to the same source image, HCC can generate a different encrypted hologram in each run.

Abstract: Techniques for efficiently generating full parallax 3-D holographic images of a 3-D real or synthetic object scene are presented. A holographic generator component (HGC) can receive a real object scene or generate a synthetic object scene. The HGC can downsample the scene by a defined downsampling factor and generate, from the downsampled scene, an intermediate object wavefront recording plane (WRP) that can be placed in close proximity to the scene. The HGC can expand and interpolate the WRP to generate the holographic images. The HGC can decompose a scene into polyphase image components (PICs), generate a WRP for the image components, sum the WRP of the PICs, and expand and interpolate the WRP to generate holographic images of the scene. The HGC can utilize look-up tables to store and use wavefront patterns of each region of an image to facilitate reducing computational operations in generating the holographic images.
