Ultrasonic signals are used to transmit sounds from a modulated ultrasonic generator to other locations from which the sounds appear to emanate. In particular, an ultrasonic carrier is modulated with an audio signal and demodulated on passage through the atmosphere. The carrier frequencies are substantially higher than those of prior systems, e.g., at least 60 kHz, and the modulation products thus have frequencies which are well above the audible range of humans; as a result, these signals are likely harmless to individuals who are within the ultrasonic fields of the system. The signals may be steered to moving locations, and various measures are taken to minimize distortion and maximize efficiency.

The system also conditions the audio signal without introducing audio signals generated from outside said first location. Finally, the system transmits the conditioned audio signal to a receiver worn by at least one of a plurality of individuals within the aforementioned fixed space. This invention is particularly useful in settings such as a football stadium, a basketball arena, a hockey arena, a baseball stadium, an auditorium, a performance area in a restaurant or cruise ship, a soccer arena, a boxing ring or wrestling ring, an automotive racing track, or any other space within which a performance takes place.

Correction of phasefront aberrations and pulse reverberations in medical ultrasound imaging
InactiveUS20020002333A1Analysing solids using sonic/ultrasonic/infrasonic wavesSurgeryUltrasonographyUltrasound imaging
A method of correcting for phasefront aberrations in ultrasound imaging uses highly spaced apart point scatterers artificially placed in the tissue being imaged. The point scatterers reflect the transmitted sound and are individually differentiated to provide singular reference points for correction of signals reflected from the surrounding tissue. The differentiation is performed by comparison of the third or fourth harmonic frequencies of the reflected signals. To ensure the necessary high dispersal of the point scatterers, high amplitude pulses of the transmitted signal destroy point scatterers in selected image regions. In an alternate embodiment, correction is performed by stochastic analysis of signals reflected from the highly dispersed point scatterers. A reference signal is compared to the second harmonic of the reflected signal to reduce noise.
