Abstract: An antimicrobial device, such as a flashlight, lantern, or lamp, is discussed herein. The antimicrobial device produces light in the ultraviolet (UV) spectrum (i.e., 150-250 nm), including 200-230 nm. The antimicrobial device includes an electron source, an extractor, and a target material. The electron source provides the electrons of sufficient energy to cause a photon to be released, whether by a target or by the electron itself. The extractor extracts the electrons from the electron source. The target material is a component at which the electron is directed. The target material can release a photon having a desired wavelength or within a desired wavelength range or cause the electron to release a photon having a desired wavelength or within a desired wavelength range.

Abstract: A technique includes spatially filtering a signal that is derived from a seismic acquisition. The filtering is associated with a filter length, and the filtering includes varying the filter length with frequency. The filtering may be used in connection with adaptive noise attenuation, which is applied to decomposed subbands. Furthermore, the filtering may be applied during the reconstruction of the signal from the subbands.
