Abstract: Examples of the present invention utilize principal component analysis (PCA) to detect cough sounds in an audio stream. Comparison of all or portions of the audio stream with a cough model may be conducted. The cough model may include a number of basis vectors may be based on initial portions of known coughs. The initial portions may be non-user specific, and accordingly the cough model may be used to detect coughs across individuals. Moreover, examples of the present invention may reconstruct the cough sounds from stored features such that the cough sounds are reconstructed but the reconstruction techniques used may be insufficient to reconstruct speech sounds that may also have been recorded, which may increase user privacy.

Abstract translation: 本发明的实例利用主成分分析（PCA）来检测音频流中的咳嗽声。 音频流的全部或部分与咳嗽模型的比较可以进行。 咳嗽模型可以包括许多基础向量可以基于已知咳嗽的初始部分。 初始部分可以是非用户特异性的，因此咳嗽模型可用于检测个体之间的咳嗽。 此外，本发明的示例可以重建来自存储特征的咳嗽声音，使得重构咳嗽声，但是所使用的重建技术可能不足以重建也可能被记录的语音，这可能增加用户隐私。

Abstract: Systems and Methods for RF Emitter Location with automatic UAS array reconfiguration. The system includes at least a first emitter of electromagnet emissions. There is an array controller and, in some situations, at least one array follower. The controller(s) each have a receiver to receive signals from the first emitter. The controller calculates the location of the first emitter based upon communications with the first emitter and any array follower.
