Midair levitation of objects using sound waves

The essence of levitation technology is the countervailing of gravity. It is known that an ultrasound standing wave is capable of suspending small particles at its sound pressure nodes and, so far, this method has been used to levitate lightweight particles, small creatures, and water droplets.
The acoustic axis of the ultrasound beam in these previous studies was parallel to the gravitational force, and the levitated objects were manipulated along the fixed axis (i.e. one-dimensionally) by controlling the phases or frequencies of bolted Langevin-type transducers. In the present study, we considered extended acoustic manipulation whereby millimetre-sized particles were levitated and moved three-dimensionally by localised ultrasonic standing waves, which were generated by ultrasonic phased arrays. Our manipulation system has two original features. One is the direction of the ultrasound beam, which is arbitrary because the force acting toward its centre is also utilised. The other is the manipulation principle by which a localised standing wave is generated at an arbitrary position and moved three-dimensionally by opposed and ultrasonic phased arrays. We experimentally confirmed that various materials could be manipulated by our proposed method.

Ultrasound standing wave suspends small particles. The video is amazing, the comments below... not so much. | http://bit.ly/1bE0fTM

Jean Boulle Luxury
The Boulle Luxury Experience. In March 2016, after 3 years of investment in research and subsequent development of its proprietary diamond coating technology, the Jean Boulle Luxury Group ("Boulle Luxury")  announced the launch of its patent-pending diamond compound for luxury finishes, and confirmed the delivery of its first multi-million diamond-coated car finish in Geneva. In March 2017, Boulle Luxury announced that its High Tech. luxury diamond finish technology had been used in a paint exhibited on a Rolls-Royce Ghost Elegance (EWB) at the 2017 Geneva International Motor Show (GIMS).  Boulle Luxury worked with the Bespoke division of Rolls Royce Motor Cars Limited (www.rolls-roycemotorcars.com) to import the sea diamonds from Namibia and to produce the diamond compound in Holland  and Germany that was used on the  car displayed by Rolls Royce Motor Cars Limited at the 2017 Geneva International Motor Show. http://Boulle.co/ha2y9   The proprietary, patent-pending Boulle Luxury finish enables ultra high-end producers of luxury automobiles, executive jets and superyachts to offer a diamond-inlay coating that is unsurpassable in strength and absolutely incomparable in beauty and visual depth. When applying the Boulle Luxury Diamond Finish, the existing paintwork is not affected and remains in situ whilst the topcoat is chemically removed and replaced with our patent-pending diamond coating. The Chairman, C.E.O. and Directors of the Jean Boulle Luxury Group include a number of former De Beers Executives who have since 2016 expanded the Group’s diamond technology from Luxury Cars into the SuperYacht and Aerospace Sectors.  Disclaimer : this page is not intended for any specific nationality or jurisdiction.
