Abstract: A method for automatic speech recognition using joint acoustic echo cancellation, speech enhancement, and voice separation includes receiving, at a contextual frontend processing model, input speech features corresponding to a target utterance. The method also includes receiving, at the contextual frontend processing model, at least one of a reference audio signal, a contextual noise signal including noise prior to the target utterance, or a speaker embedding including voice characteristics of a target speaker that spoke the target utterance. The method further includes processing, using the contextual frontend processing model, the input speech features and the at least one of the reference audio signal, the contextual noise signal, or the speaker embedding vector to generate enhanced speech features.

Abstract: A foldable personal mobility vehicle is disclosed comprising first and second units having first and second wheels being rotatable about first and second axles. A drive unit rotates the second wheel for moving the foldable personal mobility vehicle. A pivot disposed substantially parallel to the first and second axles pivotably connects the first unit to the second unit for folding the personal mobility vehicle. The foldable personal mobility vehicle may include a folding unit for automatically folding the foldable personal mobility vehicle.

Abstract: The present invention is related to novel acid functional pigment dispersing agents. In particular, the invention is directed to novel polymers with acid functional groups for use as pigment dispersants. The novel polymers comprise polymeric amides with free carboxyl functional groups having the structure: wherein PE is a polyester, PA is a polyamine and A is an anhydride. The novel pigment dispersants of the present invention are particularly effective for the dispersion of high color carbon black and organic pigments. The advantages of the novel pigment dispersants over known amine functional polymeric dispersants are several. They do not tend to discolor when exposed to UV light. They do not inhibit acid catalyzed reactions such as melamine crosslinking or react with isocyanate or catalyze the isocyanate/H2O reaction. They are non-toxic or much less toxic to aquatic organisms.

Abstract: The invention relates to acrylated chlorinated rubber, a method for making acrylated chlorinated rubber comprising reacting chlorinated hydroxyrubber and acryloyl chloride with triethylamine as a catalyst, and photocurable rubber coatings comprising acrylated chlorinated rubber.

Abstract: A metal (M) alkyl acid phosphate catalyst for the reaction of an epoxy compound with a carboxyl compound to provide a coating formulation that is stable at room temperature; that is humidity resistant, and non-yellowing, wherein the alkyl acid phosphate has the formula: (RO)n—(P═O)—(OH)m and wherein: a. each R is selected from the group consisting of: i) a C1 to C18 alkly, cycloalkyl, or aryl; ii) a linear or branched C6 to C18 alkyl substituted with —(O—CH2—CH2—)o or —(O—CH—CH3—CH2—)p, wherein o or p is from 1 to 20; iii) a &bgr;-hydroxyethyl compound, R′—X—CH2—CH—OH—CH2—, wherein R′ is a C6 to C18 alkyl or cycloalkyl or aryl, X is either —CH2—, —O— or —COO—; b. n+m=3 and n is between 2 to 1; and c. M is Zn or Sn (II) in a mole equivalent of 0.7 to 1.5 moles per mole of alkyl acid phosphate.

Abstract: The present invention is directed to novel metal organocomplexes as catalysts for the reaction of compounds with isocyanate and hydroxy functional groups to form urethane and/or polyurethane and the process employing such catalysts. More particularly, the present invention is directed to novel complexes of zirconium or hafnium with diketones or alkylacetoacetoates. These novel catalysts are useful for the production of urethanes and polyurethanes which are important in many industrial applications, such as: coatings, foams, adhesives, sealants, and reaction injection molding (RIM) plastics.
