High Frequency Ventilation [PDF]
High frequency ventilation (HFV) presents a new respiratory therapy modality that has taught us much about the theories of gas transport in the lung. Both experimental and clinical applications are summarized. Although the future clinical role of HFV remains uncertain, pediatric applications and investigation continue at the forefront of this new ...

High Frequency Audiometry [PDF]
After a brief discussion of the past use of and clinical need for high frequency hearing tests, a new technique is described that uses a special electric transduction mode: a 60-kHz carrier frequency is modulated by the desired audiofrequency. The combined signal is applied to the skin over the mastoids by Mylar-covered electrodes.

Calibration to Mitigate Near-Field Antennas Effects for a MIMO Radar Imaging System
A calibration method for a high-resolution hybrid MIMO turntable radar imaging system is presented. A line of small metal spheres is employed as a test pattern in the calibration process to measure the position shift caused by undesired antenna effects ...

High Frequency Ventilation [PDF]
Over the last six years high-frequency ventilation has been extensively evaluated both in the clinical and laboratory settings. It is now no longer the great mystery it once was, and it is now no longer believed (as many had hoped), that it will solve all the problems associated with mechanical pulmonary ventilation. Although the technique is safe and
