摘要： A system, such as a video conferencing system, is provided which includes an image pickup device, an audio pickup device, and an audio source locator. The image pickup device generates image signals representative of an image, while the audio pickup device generates audio signals representative of sound from an audio source, such as speaking person. The audio source locator processes the image signals and audio signals to determine a direction of the audio source relative to a reference point. The system can further determine a location of the audio source relative to the reference point. The reference point can be a camera. The system can use the direction or location information to frame a proper camera shot which would include the audio source.

摘要： A method of operating a radar system, including the steps of digitally sampling a received signal at a predetermined sampling rate, to periodically provide a set of selected samples, the set of selected samples including positive going ramp samples, negative going ramp samples and CW burst samples and performing a first fast Fourier transform (FFT) on the positive going ramp samples, performing a second fast Fourier transform on the negative going ramp samples and performing a third fast Fourier transform on the CW burst samples is described. Utilizing the subsequent radar operations the method further includes the steps of tracking each resulting signal from the first fast Fourier transform performing steps, tracking each resulting signal from the second fast Fourier transform performing steps and tracking each resulting signal from the third fast Fourier transform performing steps and associating any resulting signals from the tracking steps to periodically provide output signals indicative of other vehicles.
摘要翻译：一种操作雷达系统的方法，包括以预定采样速率对接收到的信号进行数字采样的步骤，以周期性地提供一组选定采样，所选择的采样集合包括正向斜坡采样，负向斜坡采样和CW脉冲串对正向斜率采样进行第一快速傅里叶变换（FFT），对负斜率采样执行第二快速傅立叶变换并对CW突发样本执行第三快速傅里叶变换。利用随后的雷达操作，该方法还包括以下步骤：从第一快速傅立叶变换执行步骤跟踪每个结果信号，从执行步骤的第二快速傅里叶变换跟踪每个结果信号，并从第三快速傅里叶变换跟踪每个结果信号，执行步骤并且将来自跟踪步骤的任何结果信号相关联以周期性地提供指示其他车辆的输出信号。
