摘要:
A system with an accompanying method is provided to improve the signal-to-noise ratio (SNR) of noisy speech by suppressing acoustic background noise. The background noise consists of narrow band noise from rotating machine, audio signals from stereo-loudspeakers of audio entertainment device, and other ambient noise. In this system/apparatus, a microphone senses the speech intermingled with the background noise, and another microphone senses the noisy background. In addition, a measurement sensor is used to measure RPM (revolutions-per-minutes) of the rotating machine and two wires are used to acquire audio signals from the stereo-loudspeakers of the audio entertainment device. Furthermore, to provide better suppression performance for the acoustic audio signals, the characteristics of these loudspeakers are used to compensate for the distortion caused by the loudspeakers. Adaptive comb filters and adaptive FIR filters are applied to estimate the ambient noise and suppress the background noise. After processing, the system outputs the enhanced speech signal with higher SNR.

In one embodiment, an apparatus is provide with a combinational logic circuit to generate a data input signal; a delay element, coupled to the combinational logic circuit, to provide a delayed data input signal in response to the data input signal. Additionally, the apparatus is provided with a system bistable circuit, coupled to the combinational logic circuit, to generate a system bistable signal in response to at least the data input signal; a shadow bistable circuit, coupled to the delay element, to generate a shadow bistable signal in response to at least the delayed data input signal. Further, the apparatus is provided with an output joining circuit, coupled to the system and the shadow bistable circuits, to provide a data output signal in response to the system and the shadow bistable signals.

Featured is a data storage back-up system for replication, mirroring and/or backing-up data including one or more first and second data storage devices that embody iSCSI, FC or alike principals and that are operably coupled to each other preferably via a WAN. The first data storage device is configured and arranged so there are two writes of data, one write to a persistent storage device from which reads are done and another write to a SAPS device wherein the data is saved using log-structured file system (LSF) techniques. After saving data to the First storage device, the data logs in the SAPS device are communicated to the second data storage device whereat a de-staging process is conducted so as to de-stage the data logs and write the de-staged data to a persistent storage device in the second data storage device.

A method and apparatus for measuring an electromagnetic field are disclosed. In accordance with the apparatus an array of substantially identical antenna elements having a substantially shorter length than a wavelength of the electromagnetic field and being equi-spaced are provided. The spacing is larger than approximately three times the length of the antenna elements. Each antenna element is for sensing the electromagnetic field at a predetermined location and for providing a signal in dependence upon the sensed field. By providing antenna elements meeting the criteria set out herein accurate electromagnetic field strengths are measurable absent significant mutual coupling and scattering effects between the antenna elements.

A removable modular duct system for conducting air in a temperature-controlled cargo container. Temperature-controlled air produced and propelled by a refrigeration unit, is conducted along the modular duct system by one or more duct sections and a transition section that conducts air from the refrigeration unit to the duct sections. The air may be discharged laterally via lateral discharge openings in the duct sections. An end section may be coupled to the duct sections to discharge air at the end of the duct system.

A method and system for the automated detection of lesions such as masses and/or tissue (parenchymal) distortions in medical images such as mammograms. Dense regions and subcutaneous fat regions within a mammogram are segmented. A background correction may be performed within the dense regions. Hough spectrum within ROIs placed in the breast region of a mammogram are calculated and thresholded using the intensity value .eta. in order to increase sensitivity and reduce the number of false-positive detections. Lesions are detected based on the thresholded Hough spectra. The thresholded Hough spectra are also used to differentiate between benign and malignant masses.
