Abstract: Methods and apparatus for supporting cached volumes at storage gateways are disclosed. A storage gateway appliance is configured to cache at least a portion of a storage object of a remote storage service at local storage devices. In response to a client's write request, directed to at least a portion of a data chunk of the storage object, the appliance stores a data modification indicated in the write request at a storage device, and asynchronously uploads the modification to the storage service. In response to a client's read request, directed to a different portion of the data chunk, the appliance downloads the requested data from the storage service to the storage device, and provides the requested data to the client.

Abstract: Disclosed is an optical flow cell (300?) comprising: a housing (910) forming; an enclosed and elongated fluid channel (920) arranged along a first axis (923); a first light guide (961) and a second light guide (962) generally concentrically arranged along a second axis (970) and on opposite side walls of the fluid channel, said first and second light guides having ends (961c,962c) removed in situ to provide a sensing gap (d).

Abstract: A storage gateway serves as an interface between processes on a customer network and a service provider. The storage gateway is located on-premise with the customer processes. To customer processes, it appears that data is stored locally. However, the storage gateway interfaces with a remote storage service to store the data. For cached gateways, the primary data store is a remote data store, while frequently accessed data may be locally cached by the gateway. Reads may be satisfied from the local cache or from virtual data storage; writes are handled so as to appropriately update data blocks in the local cache and/or in virtual data storage. For shadowing gateways, the primary data store is the local data store; reads are passed through to a local data store, and writes are shadowed to virtual data storage as well as being sent to local data store.

Abstract: In some embodiments, a head-mounted, near-eye display system comprises a stack of waveguides having integral spacers separating the waveguides. The waveguides may each include diffractive optical elements that are formed simultaneously with the spacers by imprinting. The spacers are disposed on one major surface of each of the waveguides and indentations are provided on an opposite major surface of each of the waveguides. The indentations are sized and positioned to align with the spacers, thereby forming a self-aligned stack of waveguides. Tops of the spacers may be provided with light scattering features, anti-reflective coatings, and/or light absorbing adhesive to prevent light leakage between the waveguides. As seen in a top-down view, the spacers may be elongated along the same axis as the diffractive optical elements. The waveguides may include structures (e.g.

Abstract: Systems and methods are provided that include features for determining a hover time remaining for an aircraft performing a hover maneuver. In some exemplary embodiments, the hover time remaining can be communicated to a pilot or aircrew member.

Abstract: Color-selective waveguides, methods for fabricating color-selective waveguides, and augmented reality (AR)/mixed reality (MR) applications including color-selective waveguides are described. The color-selective waveguides can advantageously reduce or block stray light entering a waveguide (e.g., red, green, or blue waveguide), thereby reducing or eliminating back-reflection or back-scattering into the eyepiece.

Abstract: A multi-stream cross correlator for spiking neural networks, where each stream contains significant stochastic content. At least one event occurs, with a fixed temporal relationship across at least two streams. Each stream is treated as a Frame Of Reference (FOR), and subject to an adjustable delay based on comparison to the Other streams. For each spike of the FOR, a timing analysis, relative to the last and current FOR spikes, is completed by comparing Post and Pre accumulators. Also, a new timing analysis is begun, with the current FOR spike, by restarting the production of Post and Pre weighting functions, the values of which are accumulated, upon the occurrence of each Other spike, until a next FOR spike. A one-spike delay unit can be used, if time-neutral conflict resolution is used. The average spike rate of the FOR can be determined and used for the Post and Pre weighting functions.

Other types of global keyboard shortcuts for targeting specific display regions might also be provided by other embodiments.

Abstract: A foldable computing device is disclosed that is configured to determine a user interface (UI) component rendering mode based on content occlusion and a prediction of user intent. The foldable computing device is configured to increase, maintain, or reduce prominence of a UI component based whether and where the UI component occludes an underlying application window or other existing UI. The foldable device may also determine an existing UI component's rendering mode based on an anticipated location of an application window associated with an application that was just launched. Furthermore, the foldable device may predict what a user is going to do with the application window, including causing any future occlusion, and adjust the UI component's rendering mode accordingly.

Abstract: In some embodiments, compositions and methods comprising reflective flowable materials, e.g., reflective liquids including reflective inks and/or liquid metals, are described. In some embodiments, a surface is contacted with a reflective flowable material, thereby forming a reflective layer on the surface. In some embodiments, the surface is a surface of a waveguide, for example a waveguide for a display device, and the flowable material coats surfaces of protrusions on the surface to form reflective diffractive optical elements. Some embodiments include a display device comprising a reflective layer of reflective flowable material.

Abstract: The invention describes a novel roofing trim saddle system and method of installing for use in roofing and siding applications where a roofing hip or ridge must be covered (finished). The various implementations herein describe the system as having a multitude of saddle brackets, each with a multitude of tabs that retain the roofing material (such as tiles, shingles, panels, slates, etc.). The saddle brackets attach to the roof via a fastener such as nails or screws that engage holes formed by slot tabs in the saddle bracket body. The slot tabs are used to correctly space and align the saddle bracket during installation. The system is strong, secure, adaptable, adjustable, customizable, thin, light-weight, self aligning, weather-proof, can be readily designed to accommodate many different roofing styles and materials on site, or can be manufactured to the needs of any particular roofing and siding application.

Abstract: Identifying shared events across spiking-neural-network data streams with significant stochastic content. The data streams are first subject to cross correlation. If two data streams are completely uncorrelated, the rate of occurrence, of cross-stream spike pairs, is an approximately uniform “r_ind” across all Time Between Events (TBE's). Any shared events create a gradient, where r_ind increases to a rate “r_shr,” for any TBE's?a Time Of Discernment (TOD). A search for the actual TOD (TOD_a) can be accomplished with a conjectured TOD (TOD_c). TOD_c is tested against an exponential decay with its rate set to a conjectured r_ind (r_ind_c). When r_ind_c=actual r_ind, equal ranges (or regions) of values, of exponential decay, represent equal probabilities. Values of TOD_c and r_ind_c are generated (at respective learning rates), until a combination is found where probabilistically equal regions receive statistically equal numbers of cross-stream events. It is then known TOD_a?TOD_c.
