    摘要: An original loudness level of an audio signal is maintained for a mobile device while maintaining sound quality as good as possible and protecting the loudspeaker used in the mobile device. The loudness of an audio (e.g., speech) signal may be maximized while controlling the excursion of the diaphragm of the loudspeaker (in a mobile device) to stay within the allowed range. In an implementation, the peak excursion is predicted (e.g., estimated) using the input signal and an excursion transfer function. The signal may then be modified to limit the excursion and to maximize loudness.

    摘要: A mobile platform includes a microphone array and is capable of implementing beamforming to amplify or suppress audio information from a sound source. The sound source is indicated through a user input, such as pointing the mobile platform in the direction of the sound source or through a touch screen display interface. The mobile platform further includes orientation sensors capable of detecting movement of the mobile platform. When the mobile platform moves with respect to the sound source, the beamforming is adjusted based on the data from the orientation sensors so that beamforming is continuously implemented in the direction of the sound source. The audio information from the sound source may be included or suppressed from a telephone or video-telephony conversation. Images or video from a camera may be likewise controlled based on the data from the orientation sensors.

    摘要: A method for adjusting volume in a headset based on accumulated acoustic energy density exposure is disclosed. A sound pressure value of a microphone positioned in a user's ear canal is measured. A current accumulated acoustic energy density exposure is determined based on sound pressure values measured during the rolling window. The maximum volume in the headset is adjusted based on a comparison of the current accumulated energy density exposure to a predetermined threshold.

    摘要: A computing device includes a touch screen display with a plurality of force sensors, each of which provides a signal in response to contact with the touch screen display. Using force signals from the plurality of force sensors, a characteristic of the contact is determined, such as the magnitude of the force, the centroid of force and the shear force. The characteristic of the contact is used to select a command which is processed to control the computing device. For example, the command may be related to manipulating data displayed on the touch screen display, e.g., by adjusting the scroll speed or the quantity of data selected in response to the magnitude of force, or related to an operation of an application on the computing device, such as selecting different focal ranges, producing an alarm, or adjusting the volume of a speaker in response to the magnitude of force.
