Lester S. H. Ngia has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8103029
    Abstract: An earset assembly including a first earpiece, a second earpiece, and an electrical circuit. The first earpiece includes an internal microphone to capture speech of a user and an internal speaker, and is positionable with respect to a first ear of the user so that the internal microphone detects the speech from the first ear of the user. The second earpiece includes an internal speaker, and is positionable with respect to a second ear of the user. The electrical circuit operatively connects the internal microphone and the internal speakers to a communication device. In an audio listening state, the electrical circuit is configured to operatively couple the internal speakers respectively to first and second audio ports of the communication device for outputting stereo audio content with the speakers, and the internal microphone is switched to an off state.

  • Patent number: 8019107
    Abstract: An earpiece may be used to detect sounds from an ear canal of a user. The earpiece may include a microphone assembly and an acoustic pathway that is at least partially defined by a hollow elongated member. The acoustic pathway fluidly couples the microphone assembly with an ear canal of the user when the earpiece is positioned with respect to the ear of the user. Sounds produced by the user travel from the ear canal through the acoustic pathway for detection by the microphone assembly. Also, the hollow elongated member behaves as an acoustic waveguide to amplify a desired frequency and/or attenuate other, less desirable, frequencies of the sounds produced by the user.

  • Publication number: 20100215198
    Abstract: An ambient sound control headset includes an external microphone and an earpiece with an internal speaker. A circuit acts upon a signal output by the external microphone to form a signal representative of a user's environment that is input to the internal speaker. Components of the signal output by the external microphone that have a corresponding volume level that are less than a predetermined threshold are allowed to pass to the internal speaker and components of the signal output by the external microphone that have a corresponding volume level that are greater than the predetermined threshold are compressed to have a volume that is less than the predetermined threshold.

  • Patent number: 7502484
    Abstract: An ear sensor apparatus includes a microphone positionable with respect to an ear canal to detect sound signals from the ear canal and to generate a corresponding output signal. The apparatus may include a seal for substantially blocking ambient sound signals from reaching the microphone and an interface to convey the output signal to a remote speech recognition apparatus. The output signal may be normalized so that the normalized output signal is more representative of speech from a user's mouth than speech detected from the user's ear.
