Abstract:
1. A portable apparatus for preventing damages from DC magnetic field, AC magnetic and electrical fields, and high frequency/microwave radiation for implantable devices comprising: a channel for detecting DC magnetic field from 0.5 Gauss to 10 Gauss, and alarms when the field exceeds a threshold set by the implantable device manufacturers; a channel for detecting AC magnetic field from 1 mGauss to 3 Gauss, and alarms when the field exceeds a threshold set by the implantable device manufacturers; a channel for detecting AC electrical field from 1 KV/m to 8 KV/m, and alarms when the field exceeds a threshold set by the implantable device manufacturers; a channel for detecting RF/microwave radiation from 0.2 mW/cm a low battery alarm circuit; and wherein the DC magnetic field detection channel further comprising: wherein the AC magnetic field detection channel further comprising: wherein the AC electrical field detection channel further comprising: wherein the RF/microwave radiation detection channel further comprising: the display unit, either analog or digital, further connected to a buzzer to provide audible alarm signal.
