Abstract: A method to process narrowband signals includes dividing the signal into segments of length N, where N optimizes filter bandwidth, FFT size, processing and memory. Each N-length segment is processed sequentially by filtering, a FFT and a peak detector that identifies the N-length segment's K largest spectral components. The frequency, bandwidth and power for the K largest spectral components are stored sequentially as N-processed data. After processing multiple N-length segments, reconstructing individual frequency spectrums for J continuous segments of the N-processed data, mapping the J reconstructed spectrums to a single spectrum, and applying the peak detector to the composite spectrum to separately store the single spectrum's K largest frequencies, with powers and bandwidths, as (N×J)-processed data. The N-length data is processed in groups of J until all N-length data is reprocessed. J may have multiple values, generating multiple processed data sets.

Abstract: The splice of the present invention includes a web having a first free end and a second free end wherein the first and second ends are positioned proximal to each other. The web encloses one or more holes adjacent to each end. The web includes a top side and an opposing underside. The splice also includes an underside patch that is adhered to the web so that the underside patch covers the hole or holes and covers each of the free ends of the web. The underside patch is adhered to the web by a reversibly releasable layer. The upper side patch is positioned substantially parallel to the underside patch. The upper side patch contacts the underside patch through one or more of the holes thereby strengthening the splice.
