Abstract: In exemplary implementations of this invention, an automultiscopic display device includes (1) one or more spatially addressable, light attenuating layers, and (2) a controller which is configured to perform calculations to control the device. In these calculations, tensors provide sparse, memory-efficient representations of a light field. The calculations include using weighted nonnegative tensor factorization (NTF) to solve an optimization problem. The NTF calculations can be sufficiently efficient to achieve interactive refresh rates. Either a directional backlight or a uniform backlight may be used. For example, the device may have (1) a high resolution LCD in front, and (2) a low resolution directional backlight. Or, for example, the device may have a uniform backlight and three or more LCD panels. In these examples, all of the LCDs and the directional backlight (if applicable) may be time-multiplexed.

Abstract: An offset estimator (e.g., a time delay, a spatial image offset, etc.) makes use of a transform approach (e.g., using Fast Fourier Transforms). The sparse nature of a cross-correlation is exploited by limiting the computation required in either or both of the forward and inverse transforms. For example, only a subset of the transform values (e.g., a regular subsampling of the values) is used. In some examples, an inverse transform yields a time aliased version of the cross-correlation. Further processing then identifies the most likely offset of the original signals by considering offsets that are consistent with the aliased output.

Abstract: Techniques for performing finite memory network coding in an arbitrary network limit an amount of memory that is provided within a node of the network for the performance of network coding operations during data relay operations. When a new data packet is received by a node, the data stored within the limited amount of memory may be updated by linearly combining the new packet with the stored data. In some implementations, different storage buffers may be provided within a node for the performance of network coding operations and decoding operations.

Abstract: Fiber draw synthesis process. The process includes arranging reactants in the solid state in proximate domains within a fiber preform. The preform is fluidized at a temperature below the melting temperature of the reactants. The fluidized preform is drawn into a fiber thereby bringing the reagents in the proximate domains into intimate contact with one another resulting in a chemical reaction between the reactants thereby synthesizing a compound within the fiber. The reactants may be dissolved or mixed in a host material within the preform. In a preferred embodiment, the reactants are selenium and zinc.

Abstract: The present invention generally relates to particles, including microgel particles, for purifying proteins and other species. In one aspect, the particles comprise a metal-chelating moiety, which may be distributed substantially evenly throughout the particle in certain embodiments. In some cases, the particles may be porous, and in some embodiments, the particles may be made sufficiently small, for example, in order to form a microgel containing the particles. Such particles may be useful, for example, in binding metal ions (for example, nickel ions) using the metal-chelating moieties. In some embodiments, such particles may also be used to bind certain analytes (for example, proteins) containing tags which attract metal ions, for example, histidine tags. Accordingly, in certain embodiments, the particles may be used for binding or trapping proteins.

Abstract: The disclosure provides methods and apparatus for release-assisted microcontact printing of MEMS. Specifically, the principles disclosed herein enable patterning diaphragms and conductive membranes on a substrate having articulations of desired shapes and sizes. Such diaphragms deflect under applied pressure or force (e.g., electrostatic, electromagnetic, acoustic, pneumatic, mechanical, etc.) generating a responsive signal. Alternatively, the diaphragm can be made to deflect in response to an external bias to measure the external bias/phenomenon. The disclosed principles enable transferring diaphragms and/or thin membranes without rupturing.

Abstract: Network architecture supports hosting and content distribution on a global scale. The architecture allows a Content Provider to replicate and serve its most popular content at an unlimited number of points throughout the world. The inventive framework comprises a set of servers operating in a distributed manner. The actual content to be served is preferably supported on a set of hosting servers (sometimes referred to as ghost servers). This content comprises HTML page objects that, conventionally, are served from a Content Provider site. A base HTML document portion of a Web page is served from the Content Provider's site while one or more embedded objects for the page are served from the hosting servers, preferably, those hosting servers near the client machine. By serving the base HTML document from the Content Provider's site, the Content Provider maintains control over the content.
Abstract: Localization and tracking system. The system includes at least one laser mounted for pointing its beam at arbitrary locations within a three-dimensional space. An object within the three-dimensional space supports a screen at its top for receiving the laser beam to create a shaped image on the screen. The shaped image on the screen is observed by a camera and computing apparatus determines the location of the object in the three-dimensional space from pointing parameters of the laser and from shape and center points of the shaped image on the screen.
Abstract: Chemical permeation enhancers (CPEs) improve access of local anesthetics to the nerve, thereby improving their performance. Surfactants, representing three CPE sub-groups: anionic, cationic, and nonionic surfactants, were co-injected with tetrodotoxin (TTX) or bupivacaine at the sciatic nerve of Sprague-Dawley rats. All enhancers produced marked concentration-dependent improvements in the frequency and duration of block with TTX but not bupivacaine. An in vitro toxicity assay showed a wide range of CPE myotoxicity, but in vivo histological assessment showed no signs of muscle or nerve damage at concentrations of CPEs that produced a half-maximal increase in the duration of block of TTX. There was no systematic relationship between the enhancers' charge or hydrophobicity and their enhancement of block duration or potency.
