  • Mouthpiece, nasal seal, head appliance, apparatus, and methods of treating sleep apnea
    Patent number: 8757158
    Abstract: A CPAP device and a method for treating sleep apnea use a head appliance with an oral adaptor comprising a tube partially inserted in a person's mouth and a diaphragm applied over the tube against the mouth, such that the lips are formed into a tight seal with the tube. A nasal seal is described comprising two rollers to which a strap is attached, so that the nasal seal is easily put in place, adjusted and maintained by rolling the rollers on the nose sides or pulling the straps.
    Type: Grant

  • Metal alkoxides and methods of making same
    Patent number: 6838404
    Abstract: A method of making a superconducting structure includes depositing a metal alkoxide on a surface of a metal and hydrolyzing the metal alkoxide on the surface to form a pinhole-free film. The metal is a superconductor. The metal alkoxide may be a compound of formula (I): M4(OPrn)16??(I); where M is zirconium or hafnium, and the purity of the compound is at least 97% as measured by NMR spectroscopy.
