Abstract: A selective audio source enhancement system includes a processor and a memory, and a pre-processing unit configured to receive audio data including a target audio signal, and to perform sub-band domain decomposition of the audio data to generate buffered outputs. In addition, the system includes a target source detection unit configured to receive the buffered outputs, and to generate a target presence probability corresponding to the target audio signal, as well as a spatial filter estimation unit configured to receive the target presence probability, and to transform frames buffered in each sub-band into a higher resolution frequency-domain. The system also includes a spectral filtering unit configured to retrieve a multichannel image of the target audio signal and noise signals associated with the target audio signal, and an audio synthesis unit configured to extract an enhanced mono signal corresponding to the target audio signal from the multichannel image.

Abstract: A multinozzle deposition system for direct write applications comprises a body including a first network of microchannels embedded therein, where the first network of microchannels extends from a parent microchannel through a series of furcations to a plurality of branching microchannels. The series consists of k generations with furcation number m where the kth generation includes mk branching microchannels. A first end of the body includes a single inlet to the parent microchannel and a second end of the body includes mk outlets from the branching microchannels, where k is an integer greater than or equal to 1 and m is an integer greater than or equal to 2. The body comprises a material having a sufficient rigidity to sustain a pressure in the microchannels of about 690 kPa or greater without distortion.

Abstract: A flexible wrist band that has a compartment is provided. The wrist band is fastened by threaded pins that pass through openings in the band. The openings are reinforced to decrease the risk that the band can be removed from the wearer without operating the fastener. The fastener requires a tool to separate the threaded pins, further securing the band and decreasing the risk of removal from the wrist of a wearer.

Abstract: An auxiliary sound/light indicating device includes a housing, in which a control circuit composed of a microcontroller, an MP3 player, a light-emitting element, and a Bluetooth module is provided. The auxiliary sound/light indicating device is wirelessly connected to a mobile communication apparatus via Bluetooth connection. The microcontroller controls the emission of sound and light, enables ringing sound programming and caller ID display setting. Through the Bluetooth connection, the auxiliary sound/light indicating device can emit sound and/or light to inform a user of an incoming call on the mobile transmission apparatus and display the caller ID, allowing the user to decide whether to answer or reject the incoming call.
