    摘要: Multiple data and images are multiplexed and sequenced utilizing split screen technology in order to minimize the recording and monitoring hardware required to process the images, providing a detailed record of the time of an event, the altitude and geographic location of the aircraft and the type and location of the event within the aircraft, greatly enhancing event reconstruction efforts. The multi-media safety and surveillance system for aircraft incorporates a plurality of strategically spaced sensors including video imaging generators for monitoring critical components and critical areas of both the interior and the exterior of the aircraft. The captured data and images are recorded and may be transmitted to ground control stations for real time or near real time surveillance. The system is tied directly into the global positioning system of the aircraft so that the precise location of the aircraft may be determined when an event occurs.

    摘要: A wireless safety and surveillance recorder system for aircraft incorporates a plurality of strategically spaced wireless sensors for monitoring critical components and operational characteristics of the aircraft. The captured data and a wireless image are transmitted to a monitor in the cockpit and recorded on a "black box" flight recorder, and may be transmitted to ground control stations for real time or near real time surveillance. The system may include a second recorder for providing redundancy and may include redundant sensors.

    摘要: A method for enhancing signal-to-noise ratio and resolution of amplitude stable signals wherein underwater acoustic data is first collected with an array of hydrophones, and then the data is digitally sampled. After producing spectra of sequential time snapshots of the digitally-sampled data, the spectra are beamformed for a single frequency. Next the low resolution beamformer response is deconvolved from the data by use of a calculated beam response pattern for the hydrophone array, so that many high-resolution estimates are created for each time snapshot. Finally, the resulting high resolution estimates are reduced to a single estimate for each spatial bin across all of the time snapshots, and the high resolution, high gain results are displayed.

    摘要: Methods and systems for spatial filtering transmitters and receivers capable of simultaneous communication with one or more receivers and transmitters, respectively, the receivers capable of outputting source directions to humans or devices. The methods and systems use spherical wave field partial wave expansion (PWE) models for transmitted and received fields at antennas and for waves generated by contributing sources. The source PWE models have expansion coefficients expressed as functions of directional coordinates of the sources. For spatial filtering receivers a processor uses the output signals from at least one sensor outputting signals consistent with Nyquist criteria representative of the wave field and the source PWE model to determines directional coordinates of sources (wherein the number of floating point operations are reduced) and outputs the directional coordinates and communications to a reporter configured for reporting information to humans. For spatial filtering transmitters a processor uses known receiver directions and source partial wave expansions to generate signals for transducers producing a composite total wave field conveying communications to the specified receivers. The methods and communications reduce the processing required for transmitting and receiving spatially filtered communications.

    摘要: A device and a method for determining a speech segment with a high degree of accuracy from a sound signal in which different sounds coexist are provided. Directional points indicating the direction of arrival of the sound signal are connected in the temporal direction, and a speech segment is detected. In this configuration, pattern classification is performed in accordance with directional characteristics with respect to the direction of arrival, and a directionality pattern and a null beam pattern are generated from the classification results. Also, an average null beam pattern is also generated by calculating the average of the null beam patterns at a time when a non-speech-like signal is input. Further, a threshold that is set at a slightly lower value than the average null beam pattern is calculated as the threshold to be used in detecting the local minimum point corresponding to the direction of arrival from each null beam pattern, and a local minimum point equal to or lower than the threshold is determined to be the point corresponding to the direction of arrival.
