Changes in the volume of pulmonary air change the conductivity distribution in the thorax. On the basis of this effect, we describe an instrument without contact to measure the volume of the lung which is suitable for applications such as monitoring of respiration in patients of sleep for the sleep apnea. The instrument is based on a magnetic coil and is positioned in a soft mattress below the subject. Current AM frequency is applied to the coil to generate eddy currents in the tissue near the drivers, which in turn generat ....etc

Transformer Basics
An electrical device that transfers energy from one circuit to another purely by magnetic inductive coupling.

Review of transformer losses
No load Loss (Excitation Loss) includes the hysteresis loss and eddy current loss.
excitation loss: energy lost by reversing the magnetic field in the core by the alternating AC.
mechanical loss: bearing friction,brush friction and windage loss

Load Loss (Impedance Loss)
Stray loss: It includes distortion of air-gap flux and also due to the due to non uniform d ....etc

ABSTRACT

Changes in the lung air volume change the conductivity distribution in the thorax. Based on this effect, we describe a noncontact instrument to measure lung volume which is suitable for applications such as monitoring of breathing in sleeping subjects for sleep apnea. The instrument is based on a magnetic coil is positionned in a flexible mattress underneath the subject. AM frequency current is applied to the coil to generates Eddy currents in nearby conductive tissues, which in turn generat ....etc

EDDY CURRENT BRAKES

EDDY CURRENT:
It is a swirling current set up in a conductor in response to a changing magnetic field.
By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change

Eddy Current Brakes
It slow an object by creating eddy currents through emi which create resistance, and in turn either heat or electricity.
Braking action is made by varying the strength of the magnetic field.
A braking force is possible when electric current is passed through the electromagnets.

THEORY OF OPERATION
Edd ....etc
