摘要： A method and apparatus for acoustically enhanced particle separation uses a chamber through which flows a fluid containing particles to be separated. A porous medium is disposed within the chamber. A transducer mounted on one wall of the chamber is powered to impose on the porous medium an acoustic field that is resonant to the chamber when filled with the fluid. Under the influence of the resonant acoustic field, the porous medium is able to trap particles substantially smaller than the average pore size of the medium. When the acoustic field is deactivated, the flowing fluid flushes the trapped particles from the porous medium and regenerates the medium. A collection circuit for harvesting the particles flushed from the porous medium is disclosed. Aluminum mesh, polyester foam, and unconsolidated glass beads are disclosed as porous media.

摘要： A method of routing control information and bearer traffic in a packet network. When a wireless communication device has established a connection in a coverage area serviced by an Access Network Controller (ANC) and a Serving Node and roams into an area serviced by a new ANC and a new Serving Node, the present invention routes control information to and from the device through the anchor Serving Node (Serving Node through which the connection was established). Bearer traffic is routed to and from the device through the ANC and Serving Node serving the area in which the wireless communication device is located.

摘要： A method of detecting narrow-band signals in an echo canceller to control the coefficient update process, echo suppression process, and the disablement of the echo canceller is provided. The method includes the steps of searching for the presence of a generic tone, searching for DTMF tones, searching for a 2100 Hz tone and, if a generic tone is found, searching for a dial tone. If a generic tone is detected on the far end signal, a tone flag is set which triggers the disablement of the echo canceller coefficient update process and the enablement of the echo suppressor process. If a 2100 Hz tone is detected, the echo canceller is disabled. If a DTMF signal is detected, DTMF flags are set which are used by the echo suppressor for suppressing the near end echo. Finally, if a dial tone is detected, dial tone flags are set which cause the disablement of the echo suppressor.

摘要： A method of synthesizing an echo path in an echo canceller is provided. The method includes the steps of obtaining near end and far end signal samples at an echo canceller, locating the echo in a background task using a whitened version of the signal, transferring the echo location information to a foreground task, and eliminating the echo in the incoming signals by filtering the signal in the location passed to the foreground task by the background task.
