Abstract: Abstract of the Disclosure A sinusoidal speech representation system is applied to the problem of speech dispersion.  The sinusoidal system first estimates and then removes the natural phase dispersion in the frequency components of the speech signal.  Artificial dispersion based on pulse compression techniques is then introduced with little change in speech quality.  The new phase dispersion allocation serves to preprocess the waveform prior to dynamic range compression and clipping, allowing considerably deeper thresholding than can be tolerated on the original waveform.

Title: Method for crosslinking amino-acid containing polymers using photoactiv atable chemical crosslinkers
Inventor: NESBURN ANTHONY BART
IPC: A61L24/10
Filed: 1989-02-15
Granted: 1997-10-28
Abstract: A method of molecularly crosslinking amino acid-containing polymers through use of a heterobifunctional cross-linking agent.  The crosslinking agent includes at least two functional moieties, the first exhibiting conventional, nucleophilic reactivity, while the second is photochemically labile.  The crosslinking agent is first reacted at the conventional site with amino acid-containing polymers to form a peptide-like bond.  The product is then subjected to photochemical activation whereby the photochemically labile moiety is converted to a reactive intermediate which bonds to an amino acid side chain of either molecules of tissue collagen and/or amino acid-containing polymers in the preparation.          Collagen crosslinked by this method can be used as a bioadhesive for sutureless closure of the skin and eye or as a superhydrated material for contact lenses, moist bandage contact lens, lens or corneal implant material, or as a drug delivery mechanism.
