Abstract: A photoconductor containing a substrate, an undercoat layer thereover comprising a resin mixture of, for example, a polyol resin, and an aminoplast resin, and a polyester, and a metal oxide; a photogenerating layer and at least one, such as 1 to about 4, charge transport layer.

Abstract: A photoconductor containing a substrate, an undercoat layer thereover wherein the undercoat layer includes, for example, a polyol resin, an aminoplast resin, a polymeric phosphate ester adhesion component, and a metal oxide; and at least one imaging layer, such as a photogenerating and charge transport layer, formed on the undercoat layer.

Abstract: A photoconductor containing a substrate, a layer thereover, which layer contains, for example, a polyol resin, an aminoplast resin, a silicone free polyester, and a metal oxide dispersed therein; and at least one imaging layer formed on the polyol resin containing layer.

Abstract: A process for preparing a charge generating layer comprising dispersing photoconductive phthalocyanine particles in a polymer matrix, the matrix comprising a polymeric film-forming reaction product of vinyl chloride, vinyl acetate, maleic acid, and hydroxyalkyl acrylate, in a solution of n-butyl acetate and methyl isobutyl ketone. An electrophotographic imaging member is also prepared comprising a charge generating layer prepared according to this process.

Abstract: A method and apparatus for treating sleep disorder breathing is disclosed having improved ability to accurately detect pharyngeal wall vibration or other apneic events. An interface or mask is placed over a patient's airway. The interface is coupled to a source of pressurized gas. A respiration-related variable, namely the total pressure in the interface, is measured or sampled. The respiration-related variable is input into an artificial neural network trained to recognize patterns characterizing sleep disorder breathing. Responsive to recognition by the artificial neural network of sleep disorder breathing, pressurized gas is supplied to the patient's airways through the interface.
