Abstract
The present invention describes systems and methods for creating a virtual force field. A field source may be scanned over a region of interest on an object using a scanning technique such as vector scanning or raster scanning. The techniques disclosed herein describe applying the force field over volumetric (spatial) regions that can extend beyond the dimensions of the focal region of the force-field source (e.g., acoustic, electromagnetic, or optical source). The present invention may equally apply to multiple processes linked by cause and effect that exhibit unequal time dependence.
Claims20
A method of creating a virtual force field comprising the steps of:
- applying a force field to a first region on an object creating a first focal region/maximum, said application causing an object response followed by a refractory periods;
- and
- applying said force field to a second region of said object during said refractory period creating a second focal region/maximum.
An ultrasound transducer comprising:
- a multi-axis spatial controller, said controller steering an ultrasound beam, said controller generating spatial coordinates of a focal region;
- a modulation waveform generator, said modulation waveform generator receiving said spatial coordinates from said controller, said modulation waveform generator having a look-up table to output an electrical signal that depends on the spatial coordinates of the focal region;
- a second waveform generator, said second generator outputting a carrier frequency sinusoid, said sinusoid output being modulated by said modulation generator;
- an amplifier, said amplifier being excited by said second generator to release an amplifier output;
- and
- an electrical impedance matching network, said network coupling said amplifier output to said ultrasound transducer.
A method of creating a virtual force field comprising the steps of:
- providing a liquid object, said liquid object having particles suspended therein;
- applying an ultrasound beam to the liquid object creating a first focal region;
- and
- moving said particles along a path away from the first focal region, in response to the ultrasound beam.
