Embodiments of a needle insertion system and method are disclosed. One method embodiment includes transmitting a sound beam along an axis to contact a blood vessel; receiving the reflected sound beam from the blood vessel; processing the reflected sound beam to detect the location of the blood vessel; and, responsive to the detection, receiving a needle in a guideway that is oriented parallel to the axis.

Needle insertion systems and methods

The present invention involves an apparatus for implementing hydro-acoustic therapy for the lungs on a patient and a method for the hydro-acoustic therapy (HAT) for the lungs. The HAT apparatus includes a chamber filled with a fluid, particularly water. The HAT apparatus also has an acoustic generator for generating low frequency acoustic waves in the fluid. A patient is positioned in the chamber and partially submersed in the fluid for treatment. In another aspect, a method for implementing hydro-acoustic therapy for the lungs includes the step of placing a person in the apparatus described above such that a body of the person is immersed in said occurs. Then, introducing acoustic vibrations into the fluid. The vibrations, if properly tuned, cause the mobilization of respiratory secretions in the person.

A state switched acoustic has a stiffness element having a zero potential energy state and a plurality of controllable stiffness states. A mass is coupled to the stiffness element so that the stiffness element and the mass are capable of resonating at a resonant frequency. A system changes the stiffness state of the stiffness element from a first stiffness state to a second stiffness state while the mass is in motion and stiffness element is in a zero potential energy state so as to change the resonant frequency of the transducer. In a method of changing resonant frequency of a mechanical system, a parameter of the system is dynamically changed while the system is in an energy state that will allow changing the resonance parameter without disrupting the resonance of the system.

State switched acoustic transducer

A system and method for measuring the acoustically induced vibrations within a living organism. The object is ensonified to set it into low frequency vibration. A continuous wave beam of ultrasonic energy is transmitted along one path and focused at the tissue to be investigated. A focused transducer receives the reflected beam along a second axis such that the intersection of the transmitted and received beams define a small, concentrated region positioned at the object under investigation. The received beam is phase modulated by the amplitude of vibration of the object producing sidebands whose amplitude can be ratioed to the amplitude of the high frequency peak to determine the absolute amplitude of the low frequency vibration.
