  • Publication number: 20190279610
    Abstract: An earpiece for real-time audio processing of ambient sound includes an ear bud that provides passive noise attenuation to the earpiece such that exterior ambient sound is substantially reduced within an ear of a wearer, an exterior microphone that receives ambient sound and converts the received ambient sound into analog electrical signals, and an analog-to-digital converter that converts the analog electrical signals into digital signals representative of the ambient sounds. The earpiece further includes a digital signal processor that performs a transformation operation on the digital signals according to instructions received from a mobile device, the transformation operation transforms the digital signals into modified digital signals, a digital-to-analog converter that converts the modified digital signals into modified analog electrical signals, and a speaker that outputs the modified analog electrical signals as audio waves.

  • Patent number: 10325585
    Abstract: Ambient sound is converted into digital signals. A processor performs active noise cancellation and/or a transformation operation that is distinct from the active noise cancellation on the digital signals. The active noise cancellation and the transformation operation transform the digital signals into modified digital signals. The modified digital signals are converted into modified analog signals. The modified analog signals are outputted as audio waves. An interior microphone is configured to output an output signal to the processor in response to receiving the modified analog signals. In response to receiving the output signal from the interior microphone, the processor is configured to determine whether the modified digital signals produce desired audio waves.

  • Patent number: 7964653
    Abstract: A polyol composition contains a polyaminochlorophenylmethane mixture (A) and a polyol (B), in which the component (A) is uniformly dissolved in the component (A) in a weight ratio of 30/70 to 60/40. The component (A) includes 50 to 70% by weight of a specific binuclear polyaminochlorophenylmethane compound, 20 to 40% by weight of a specific trinuclear polyaminochlorophenylmethane compound and 5 to 10% by weight of a specific tetranuclear or higher polyaminochlorophenylmethane compound. The polyol composition exhibits excellent miscibility and dissolution stability, is liquid and enables molding of a foamed article for abrasive in a simple two-component mixing casting machine. According to the present invention, water serving as a foaming agent can be added to the polyol composition containing MBOCA, and the composition for a two-component curable abrasive foam can be held to a temperature equal to or lower than the boiling point of water, thus avoiding water from evaporating upon molding.
