Abstract: Embodiments provide an innovative solution for finding the beamforming vectors which are based on classical BD. Particularly, embodiments exploit the principle of coherence interval, which suggests that the amplitude and phase of the channel is relatively constant over a small interval on a given t-f resource and thus, there is no need to re-compute the beamforming weights again. Instead, the previously computed weights (on the small interval of the given t-f resource) can be updated. To do this less-computationally-intense update operation, embodiments further exploit a principle from perturbation theory; namely, that when there is a minor change in the entries of a matrix, the decomposition of the matrix and the rank does not change heavily. In embodiments, the need to re-compute the BF weights can therefore be avoided.

Abstract: In a method for adjusting the sensitivity of a photodetector, the bandgap of the photodetection material is adjusted by inducing strain in the photodetection material. Such adjustments can be made in situ and continuously, in a reproducible and repeatable manner. In embodiments of the method, the photodetection material is graphene, carbon nanotubes or graphene nanoribbon. The use of graphene permits a dynamically-adjustable sensitivity over a dynamic range of radiation having wavelengths of 1.38 microns or less, up to at least 60 microns. In an adjustable photodetector, a graphene layer is suspended over a silicon substrate by a layer of an insulating material. Adjusting the voltage across the graphene layer and the silicon substrate induces strain in the graphene layer by electrostatic attraction.

Abstract: A novel water flow facilitator for granular filter devices that operate under gravity and contain granular particles, further consisting of plastic pellets that are 2 to 100 times, preferably 5 to 20 times larger than the granular particles; the plastic pellets having an aspect ratio of 0.5 to 10, preferably 1 to 4; that comprise about 1 to 50%, preferably 5 to 15% of the weight of the filter media; that have a specific gravity of 0.5 to 2, preferably 0.9 to 1.5. The plastic pellets should contain antimicrobial agents that protect the granular media from microbiological growth. The plastic pellets are made from any of the following plastics: polyolefins, various kinds of polyacrylates, polyvinyl polymers, nylon, polycarbonates etc. The plastic pellets may contain fillers such as calcium carbonate, titania, silica, or alumina.

Abstract: The invention is a granular media filter for in-line liquid applications that allows media as fine as 44 micron to be used to increase the removal of contaminants from the liquid with adequate flows consisting of a specific arrangement. A flow distributor has a non-woven fiber web welded to it; followed by a mixture of fine particle media (finer than 20×50 mesh); followed by a compressible chlorine resistant open cell polyurethane foam, then a 5 micron rated meltblown fiber tube attached to the outlet end by melt adhesive on one end and closed with a plastic plug on the other end. The foam can be either polyurethane or polyolefin, and it can be either open cell foam, or reticulated and open cell foam. A preferred embodiment includes within the fine particle media 10% by weight of flow-enhancing antimicrobial plastic pellets, about 4-5 mm in diameter and having an aspect ratio of 2-3, the pellets encapsulating an antimicrobial additive.

Abstract: A granular activated carbon consists essentially of particles of activated carbon, and less than 1% by weight of an antimicrobial agent, wherein said antimicrobial agent does not desorb from said particles when washed in a polar solvent. Additionally, a method of making a granular activated carbon that exhibits antimicrobial properties is also disclosed.
