  • Patent number: 9656071
    Abstract: A method for adjusting parameters of a hearing prosthesis system includes adjusting a control to shift an audiogram associated with a first stimulator, applying a prescription rule using the shifted audiogram to adjust a cross-over frequency that defines a first frequency range and a second frequency range. The first stimulator is configured to apply stimulation signals in the first frequency range and a second stimulator is configured to apply stimulation signals in the second frequency range. The method also includes applying the prescription rule using the shifted audiogram to determine gain and maximum power output (MPO) levels for the first frequency range associated with the first stimulator.
    Type: Grant

  • Patent number: 8874226
    Abstract: The present application discloses systems, methods, and articles of manufacture for fitting a hearing prosthesis to a hearing prosthesis recipient. Some embodiments include generating a first set of two or more stimulation signals via a corresponding set of two or more channels of a hearing prosthesis, reducing the corresponding stimulation levels of the stimulation signals of the first set of two or more stimulation signals in response to receiving an indication that a sound sensation corresponding to the first set of two or more stimulation signals is uncomfortably loud, and generating a second set of one or more stimulation signals at the reduced stimulation levels via a first subset of one or more channels.

  • Patent number: 6676848
    Abstract: Corrosion protection of magnesium and aluminum alloys in engine coolants and heat-exchange fluids is achieved by the use of a select group of aliphatic and aromatic carboxylate acids or the alkaline metal, ammonium or amine salts thereof in combination with a fluoride and/or a fluorocarboxylic acid or salt thereof. These compositions have been found to significantly improve the high temperature magnesium corrosion protection properties of coolants, and are of use in automobile engine coolant systems.
