A method for reducing noise associated with an audio signal received through a microphone sensor array is provided. The method initiates with enhancing a target signal component of the audio signal through a first filter. Simultaneously, the target signal component is blocked by a second filter. Then, the output of the first filter and the output of the second filter are combined in a manner to reduce noise without distorting the target signal. Next, an acoustic set-up associated with the audio signal is periodically monitored. Then, a value of the first filter and a value of the second filter are both calibrated based upon the acoustic set-up. A system capable of isolating a target audio signal from multiple noise sources, a video game controller, and an integrated circuit configured to isolate a target audio signal are included.

A method and apparatus extract a signal component of a measured signal using one of two methods. If the signal component in the measured signal is a periodic signal with a certain well-defined peak-to-peak intensity value, upper and lower envelopes of the measured signal are determined and analyzed to extract said signal component of the measured signal. This signal component can further be used to calculate a desired parameter of the sample. The DC component of the signal is determined as the median value of the upper envelope, and the AC component is determined as the median value of the difference between the upper and lower envelopes. If the signal component of the measured signal is a periodic signal characterized by a specific asymmetric shape, a specific adaptive filtering is applied to the measured signal, resulting in the enhancement of the signal component relative to a noise component. This adaptive filtering is based on a derivative of the Gaussian Kernel having specific parameters matching the characteristics of the signal component.

A personal sound link module (60) is inserted into a tunnel (40) made through the soft tissue connecting the retro-auricular space (50) with the ear canal (30). The module contains an acoustic transducer (65), located at the distal part (68) of the module, close to or inside the ear canal, an antenna (64) that receives and also potentially sends signals to a remote source, signal processing circuitry (67), telemetry circuitry (69), a power source (66) that powers the module, and possibly a microphone (63). Signals transmitted from a remote source are received through the antenna and telemetry circuitry, processed, and presented to the acoustic transducer, where they are converted to sound waves broadcast into the user's ear canal. The remote source may be a radio station, radio receiver, CD player, DVD player, tape player, audio system, telephone, TV receiver or station, or other source of audio signals intended to be heard privately by the user.

A headphone apparatus the acoustic characteristics of which can be easily changed in accordance with the type of content the user wants to listen to. An adjusting knob provided on the housing of the headphone apparatus is moved, closing an opening made in a baffle. As a result, an acoustic space defined by the inner side of the baffle and an ear pad is more closed, thus increasing the level of low-frequency components of the sound generated by a sound-generating unit. Hence, the acoustic characteristics of the apparatus can be easily changed as the user desires.

A thin film transistor includes, as a buffer layer, a semiconductor layer which contains nitrogen and includes crystal regions in an amorphous structure between a gate insulating layer and source and drain regions, at least on the source and drain regions side. As compared to a thin film transistor in which an amorphous semiconductor is included in a channel formation region, on-current of a thin film transistor can be increased. In addition, as compared to a thin film transistor in which a microcrystalline semiconductor is included in a channel formation region, off-current of a thin film transistor can be reduced.

A toothbrushing monitoring device for a user includes a sensor coupled with the toothbrush for measuring toothbrushing patterns, a recording device coupled with the sensor, and a comparator. The recording device records data relating to the user's preferred toothbrushing patterns in a first mode, which is used to establish toothbrushing pattern reference data. The comparator compares toothbrushing patterns measured by the sensor and the toothbrushing pattern reference data, which may be output to an output device. In one example, the sensor consists of only an accelerometer.

A computer-implemented system is provided, including a network consisting of the Internet, PSTN, and CATV network. The network is connected to multiple users' client systems, and also to multiple service provider systems. Each user has a user profile stored in a User Preference Database, while each service provider has service parameters defining the type of its service stored in a Service Database, both of which are connected to the network. The system further includes a Gatekeeper Server, which establishes voice communication among the client systems and the service provider systems. In operation, upon receiving a user's request for service, the Gatekeeper Server identifies one or more service providers whose service parameters match the user's request for service and the user's profile. Upon the user's selection of one such service provider, the Gatekeeper server automatically selects and establishes a preferred mode of voice connection between the user and the selected service provider.

An individual consumer borrower accessing a person-to-person lending website is provided an opportunity to have a loan request wholly or partially satisfied by a financial institution at loan terms from the financial institution. The financial institution, for example, can receive information about a person-to-person loan request, determine whether to authorize a financial institutional loan, offer a loan to the individual on terms determined by the financial institution, and issue the loan to an individual consumer borrower responsive to approval of the terms. Prior to an auction, the individual consumer can choose an immediate loan offer having financial institution terms or choose to solicit individual consumer loan offers with more favorable terms through the person-to-person lending website. The financial institution can also offer a gap filling loan for a deficiency amount so that the loan request can be partially satisfied by individual consumer loan offers.

When a base station apparatus and a mobile station apparatus communicate with each other using a wider frequency band consists of multiple carrier components, efficient communication is achieved without increasing control information (control signal) notified from the base station apparatus to the mobile station apparatus. The base station apparatus and the mobile station apparatus communicate with each other such that each of multiple uplink carrier components corresponds to each of multiple downlink carrier components or multiple downlink carrier component groups including multiple downlink carrier components.

Methods, systems, and devices are described for wireless communication. A device may use enhanced reporting mechanisms to support control information reporting on shared spectrum. In some cases, a device may utilize enhanced component carriers (eCCs) for data transmissions. In one example, the device may transmit control information (e.g., ACK/NACK, CSI, etc.) to a corresponding device using a CCA exempt transmission (CET). In another example, a device may report control information quasi-periodically. For instance, a device may be assigned a specified interval and a control feedback window for reporting control information (e.g., CSI). The window may provide a duration prior and subsequent to the specified interval during which a UE may transmit control information. For example, the device may perform a CCA reserving the channel for a duration that does not include the specified interval but may transmit feedback information based on determining the specified interval falls within the assigned window.

Reproduction of stereophonic audio information over a single speaker requires summing multiple stereo channels. When signals having approximately equal magnitudes and approximately opposite phases at a frequency are added together, the audio information at the frequency is lost. To preserve areas of potential cancellation and potential audio information loss, the audio enhancement system adjusts the phase relationship between the stereophonic channels. To avoid the loss of the spatial content of the stereo signal, the audio enhancement system determines the difference information that exists between different stereophonic channels. The audio enhancement system enhances the difference information and mixes the enhanced difference information with the phase adjusted signals to generate an enhanced monophonic output.
