Cellular telephone, personal digital assistant and pager unit with capability of short range radio frequency transmissions

Номер: US20120034873A1
Автор: Peter V. Boesen
Принадлежит: Individual

A cellular telephone system, including a cellular telephone transceiver unit, an ear piece which receives the voice vibrations of a user, and a wireless linkage operatively connecting the ear piece to the cellular telephone transceiver unit, allows a user to be in a hands-free mode when using a cellular telephone. The cellular telephone transceiver unit includes a personal digital assistant and a pager with a vibration module. The ear piece generally uses a bone sensor along with an air sensor placed in the external auditory canal of the user to detect the voice vibrations of the user. Further, a speaker is included in the ear piece to allow the user to hear incoming data from the cellular telephone transceiver. The wireless linkage uses low power radio frequency waves to send and receive signals between the ear piece and the cellular telephone transceiver unit. Both the ear piece and the cellular telephone transceiver unit require power which is supplied by batteries. Both the ear piece and the cellular telephone transceiver may be recharged by simply placing them in a docking station.

Microphone Array System

Номер: US20120076316A1
Автор: Manli Zhu, QI Li
Принадлежит: LI Creative Technologies Inc

A method and system for enhancing a target sound signal from multiple sound signals is provided. An array of an arbitrary number of sound sensors positioned in an arbitrary configuration receives the sound signals from multiple disparate sources. The sound signals comprise the target sound signal from a target sound source, and ambient noise signals. A sound source localization unit, an adaptive beamforming unit, and a noise reduction unit are in operative communication with the array of sound sensors. The sound source localization unit estimates a spatial location of the target sound signal from the received sound signals. The adaptive beamforming unit performs adaptive beamforming by steering a directivity pattern of the array of sound sensors in a direction of the spatial location of the target sound signal, thereby enhancing the target sound signal and partially suppressing the ambient noise signals, which are further suppressed by the noise reduction unit.

Audio decoder for wind and microphone noise reduction in a microphone array system

Принадлежит: GoPro Inc

An audio system encodes and decodes audio captured by a microphone array system in the presence of wind noise. The encoder encodes the audio signal in a way that includes beamformed audio signal and a “hidden” representation of a non-beamformed audio signal. The hidden signal is produced by modulating the low frequency signal to a high frequency above the audible range. A decoder can then either output the beamformed audio signal or can use the hidden signal to generate a reduced wind noise audio signal that includes the non-beamformed audio in the low frequency range.

A loudspeaker battery charging device comprises a three-position selector that establishes one of a first, second, or third charging mode for charging a battery of a loudspeaker. The first charging mode pertains to an off state of the loudspeaker. The second charging mode pertains to an on state of the loudspeaker. The third charging mode pertains to a fast charge state of the loudspeaker. A controller receives a signal from the three-position power switch indicating a selected charging mode of the first, second, or third charging mode. A switch circuit outputs a first power-supplying level in response to the first or second charging mode and outputs a second power-supplying level higher than the first power-supplying level in response to the third charging mode.
