Drive technology for phased array systems

摘要

SUMMARY A variety of techniques have been described for driving a phased array system, including the following systems, and specifically for acoustic phased arrays with applications in aerial haptics, parametric audio, acoustic levitation and acoustic imaging: 1) It is possible to reduce the effects of air changes to provide a consistent haptic experience; 2) produce trap points in the air; 3) vectors for producing more consistent haptic effects. 4) defining one or more control points or regions in space via a controlled acoustic field; and 5) defining the acoustic basis function 6) perform efficient evaluation of complex-valued functions for large amounts of throughput; 7) generate Krylov small regions of the matrix. And 8) different from that used to create the acoustic basis functions, the control points and / or areas, to maximize the purpose described.
