Abstract: In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.

Abstract: An automated system and method for classifying audio or audio/video signals as music or non-music is provided. A spectrum module receives at least one digitized audio signal from a source and generates representations of the power distribution of the audio signal with respect to frequency and time. A first moment module calculates, for each time instant, a first moment of the distribution representation with respect to frequency and in turn generates a representation of a time series of first moment values.A degree of variation module in turn calculates a measure of degree of variation with respect to time of the values of the time series and produces a representation of the first moment time series variation measuring values.

Abstract: A central processing unit (CPU) 10 comprises an external control memory for storing microinstructions which correspond to macroinstructions read from a system memory. The microinstructions are 56 bits in length and are read in 28-bit segments. CPU 10 also comprises an internal memory management unit (MMU) 18 which comprises a plurality of address translation entry (ATE) registers four of which are permanent and sixteen of which are temporary in that the storage of a new translation entry occurs in a least recently used temporary translation entry register. CPU 10 also comprises a plurality of status register bits, some of which are settable only by predefined microinstructions. All of the status register bits are branchable. CPU 10 further comprises a condition code register the state of which may be determined by input signal pins. CPU 10 also comprises address generation logic which may generate a 24, 31 or 32 bit address upon a 32-bit address bus.
