Abstract: A light fixture is provided with increased light output, uniformity of brightness and color and controlled lighting non-lambertian distributions by use of an optical element that functions simultaneously as an outcoupling TIR light guide and a direct throughput lens. It provides typical benefits of an edgelit light guide design including thin forms and shallow depth, extended emitting area, and single or dual peak off axis light distributions particularly useful in applications such as indirect illumination of ceilings, wall washing, aisle lighting, exterior façade lighting and area lighting as well as other lighting applications. Additionally, areas typically dedicated to bezels or edge reflectors can be greatly reduced or eliminated due to decreased hotspotting to provide a fixture face with very high percentage of light emitting area. Embodiments are described for direct, indirect, and direct indirect configurations.

Abstract: The present disclosure provides an optical arrangement that provides, when in operation, more uniform angular light distribution emissions into an environment. Furthermore, the present disclosure seeks to provide a lighting assembly employing the optical arrangement to provide, when in operation, more uniform angular light distribution emissions into an environment. The present disclosure seeks to provide a solution to a problem of non-uniform angular distribution of light leading to visual discomfort, spatial discontinuity in output light distribution, and non-availability of optical arrangements that enhance optical properties of light emissions and smooth t light emissions. Furthermore, the present disclosure seeks to provide a solution to a problem of, for example, wastage of electrical energy due to improper lighting emissions into an environment.

Abstract: A method comprising: receiving, at a block device interface, an instruction to write data, the instruction comprising a memory location of the data; copying the data to pinned memory; performing, by a vector processor, one or more invertible transforms on the data; and writing the data from the pinned memory to one or more storage devices asynchronously; wherein the pinned memory of the data corresponds to a location in pinned memory, the pinned memory being accessible by the vector processor and one or more other processors.

Abstract: A method comprising: receiving a request to write data at a virtual location; writing the data to a physical location on a persistent storage device; and recording a mapping from the virtual location to the physical location; wherein the physical location corresponds to a next free block in a sequence of blocks on the persistent storage device.

Abstract: The present invention is directed to novel tools and systems for controlling narrow band data (e.g., data communication and telecommunications) pathways through selective engagement with one or more narrow band platforms of an omni-grid system. These methods further comprise enhanced compression methods suitable to structure the data for controlled data flow in an omni-grid system. In particular, the tools and the systems of the present invention provide improved transmission to off-grid environments (e.g., stronger, faster, and stable with less latency, jitter, and/or packet loss under difficult/harsh signal conditions), including in the context of an urban environment where one may be off the grid temporarily due to an emergency, in educational settings, as well as for use in geographically remote locations not in proximity to physical network infrastructure (e.g., for Internet of Things data access).

Abstract: A single edge lit lighting module is disclosed which produces tailored light distributions valuable in many illumination applications. The light distributions attainable using the invention include, but are not limited to, symmetric and asymmetric batwing distributions, asymmetric distributions for perimeter lighting and symmetric distributions. The invention's unique single edge lit construction provide the means for achieving this without need for conventional two lit edges and within a compact form factor with narrow width, particularly well-suited for linear lighting fixtures. Various embodiments also provide means for adjusting light distributions dynamically to control light output characteristics by controlling the input signals to the LED board included in the assembly.

Abstract: The invention provides nanostructure composite porous silicon and carbon materials, and also provides carbon nanofiber arrays having a photonic response in the form of films or particles. Composite materials or carbon nanofiber arrays of the invention are produced by a templating method of the invention, and the resultant nanomaterials have a predetermined photonic response determined by the pattern in the porous silicon template, which is determined by etching conditions for forming the porous silicon. Example nanostructures include rugate filters, single layer structures and double layer structures. In a preferred method of the invention, a carbon precursor is introduced into the pores of a porous silicon film. Carbon is then formed from the carbon precursor.

In some exemplary embodiments, the light source itself can include a heat sink disposed within a sleeve, a base disposed at the bottom of the sleeve and conductively coupled with the heat sink, an LED component disposed on the top of the heat sink, and one or more optical distributors associated with either or both of the heat sink and sleeve. For example, there can be both an inner and optical distributor, with at least the outer distributor being removable and replaceable. The present disclosure enables LEDs to perform effectively in lighting fixtures such as chandeliers where such performance was previously not achievable. Additionally, the present disclosure provides for ways to retrofit existing lighting fixtures having incandescent lights with LED modules.
