Abstract: One or more sound producers disrupt auditory communications among animals in a defined locale. The sound is defined by (i) a frequency range commensurate with a communication frequency range used by at least one species to carry out auditory communications, (ii) colored noise in the frequency range, and (iii) a sound level of the colored noise in the frequency range at a perimeter region of the defined locale not to exceed approximately a peak sound level associated with auditory communications of one or more species.

Abstract: A system and method for authenticating a radio-frequency identification tags based on the features of the modulation features of the RFID signal. Dynamic wavelet fingerprint features are extracted from the signal by applying a wavelet transform to the signal to determine wavelet coefficients at a plurality of times and frequency scale values, creating a binary image from the wavelet coefficients, and measuring image features of at least one fingerprint object in the binary image. The measured features of the binary image fingerprint objects are compared to a database of features for the signal's EPC to authenticate the RFID tag.

Abstract: Methods and devices are described that enable real-time, hand-held diagnostic ultrasonography for use in dental practice. The methods and devices utilize circumferential surface wave modes that are highly sensitive to small surface and near surface flaws. In addition, these surface waves can propagate between the teeth, following the curvature of the tooth.
