Abstract
Apparatus and methods for ultrasonic coupling using ultrasonic radiation pressure generating are provided. Ultrasonic energy is generated to propagate in the form of ultrasonic waves in a medium coupled to a second element. The ultrasonic energy is converged in the medium to couple the medium to an object located at a distance from the second element. Additional apparatus and methods are disclosed.
Claims28
An apparatus comprising:
- an ultrasonic transducer coupled to an electromagnetic radiation source and configured to generate ultrasonic energy to propagate in the form of ultrasonic waves;
- and
- a second element coupled to a medium, the second element to converge the ultrasonic energy in the medium to couple the medium to an object located at a distance from the second element, the medium comprising a fluid;
- and
- a fluid container formed by walls attached to the second element to contain the fluid, the ultrasonic transducer being energized by applying to the electromagnetic radiation source a radio frequency (RF) signal for a time period to lift a fluid surface level at a portion of a fluid surface to form a fluid mound.
