    Abstract: Provided herein are compositions, CO2-permeable/selective membranes and related methods of making and using the membranes. Ionically cross-linked poly(ether)-based membranes were prepared for applications relating to CO2. These films were studied for their thermal curing behavior using DSC. The resulting free-standing membranes have Tgs near ?64° C., TdS up to 230° C., and Young's modulus up to 4.2 MPa. These membranes showed CO2 permeabilities of 84-110 Barrer and CO2/N2 selectivity of 20-40.

  • Publication number: 20190101954
    Abstract: A method for displaying a near-eye light field display (NELD) image is disclosed. The method comprises determining a pre-filtered image to be displayed, wherein the pre-filtered image corresponds to a target image. It further comprises displaying the pre-filtered image on a display. Subsequently, it comprises producing a near-eye light field after the pre-filtered image travels through a microlens array adjacent to the display, wherein the near-eye light field is operable to simulate a light field corresponding to the target image. Finally, it comprises altering the near-eye light field using at least one converging lens, wherein the altering allows a user to focus on the target image at an increased depth of field at an increased distance from an eye of the user and wherein the altering increases spatial resolution of said target image.

  • Patent number: 9934714
    Abstract: System and method of displaying images in temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original video with a target temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The multiple layers are refreshed in staggered intervals to synthesize a video with an effective refresh rate exceeding that of each individual display layer, e.g., by a factor equal to the number of layers. Further optically averaging neighboring pixels can minimize artifacts.

  • Patent number: 9892669
    Abstract: System and method of displaying images in spatial/temporal superresolution by multiplicative superposition of cascaded display layers integrated in a display device. Using an original image with a target spatial/temporal resolution as a priori, a factorization process is performed to derive respective image data for presentation on each display layer. The cascaded display layers may be progressive and laterally shifted with each other, resulting in an effective spatial resolution exceeding the native display resolutions of the display layers. Factorized images may be refreshed on respective display layers in synchronization or out of synchronization.

  • Patent number: 9643123
    Abstract: Methods and compositions useful, for example, for physical solvent carbon capture. A method comprising: contacting at least one first composition comprising carbon dioxide with at least one second composition to at least partially dissolve the carbon dioxide of the first composition in the second composition, wherein the second composition comprises at least one siloxane compound which is covalently modified with at least one non-siloxane group comprising at least one heteroatom. Polydimethylsiloxane (PDMS) materials and ethylene-glycol based materials have high carbon dioxide solubility but suffer from various problems. PDMS is hydrophobic but suffers from low selectivity. Ethylene-glycol based systems have good solubility and selectivity, but suffer from high affinity to water. Solvents were developed which keep the desired combinations of properties, and result in a simplified, overall process for carbon dioxide removal from a mixed gas stream.

  • Patent number: 9582075
    Abstract: A method to drive a pixelated display of an electronic device arranged in sight of a user of the device. The method includes receiving a signal that encodes a display image, and controlling the pixelated display based on the signal to form the display image in addition to a latent image, the latent image being configured to illuminate an eye of the user with light of such characteristics as to be unnoticed by the user, but to reveal an orientation of the eye on reflection into a machine-vision system.

  • Patent number: 9576340
    Abstract: A technique for efficiently compressing rendered three-dimensional images in a remote rendering system adds a novel render-assisted prediction function to an existing video compression framework, such as the standard H.264/5 framework. Auxiliary rendering information is separated from rendering information used to describe a reference image by a server system. A client system may alter the auxiliary data and generate a new image based on the reference image and rendered scene information from the auxiliary data without creating additional network bandwidth or server workload.

  • Patent number: 9437039
    Abstract: A method of generating an image. The method includes simulating a presence of at least one light source within a virtualized three dimensional space. Within the virtualized three dimensional space, a light sensing plane is defined. The light sensing plane includes a matrix of a number of pixels to be displayed on a display screen. The method further includes using a light transport procedure, computing a gradient value for each pixel of the matrix to produce a number of gradient values. The gradient computation involves selecting a plurality of light path pairs that contribute to a pixel wherein the selection is biased towards selection of more light paths that pass through pixels having larger gradient values. The plurality of gradient values are converted to a plurality of light intensity values which represent the image.

  • Patent number: 9305392
    Abstract: Techniques are disclosed for tracing a ray within a parallel processing unit. A first thread receives a ray or a ray segment for tracing and identifies a first node within an acceleration structure associated with the ray, where the first node is associated with a volume of space traversed by the ray. The thread identifies the child nodes of the first node, where each child node is associated with a different sub-volume of space, and each sub-volume is associated with a corresponding ray segment. The thread determines that two or more nodes are associated with sub-volumes of space that intersect the ray segment. The thread selects one of these nodes for processing by the first thread and another for processing by a second thread. One advantage of the disclosed technique is that the threads in a thread group perform ray tracing more efficiently in that idle time is reduced.
