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/cm2 to 5 mW/cm2, and alarms when the field exceeds a threshold set by the implantable device manufacturers; and
a low battery alarm circuit; and
wherein the DC magnetic field detection channel further comprising;
a DC magnetic field sensor;
a DC signal processor;
a comparator; and
an analog display unit comprising a meter, or bar LED display, or vibrator, or flashing light, to provide visual and mechanical alarm signal for this application, or a digital display unit comprising individual LEDs or bar LED display to provide visual alarm signal;
wherein the AC magnetic field detection channel further comprising;
an AC magnetic field sensor;
an AC signal processor;
a comparator; and
an analog display unit comprising a meter, or bar LED display, or vibrator, or flashing light, to provide visual and mechanical alarm signal for this application, or a digital display unit comprising individual LEDs or bar LED display to provide visual alarm signal;
wherein the AC electrical field detection channel further comprising;
an AC electrical field sensor;
an AC signal processor;
a comparator; and
an analog display unit comprising a meter, or bar LED display, or vibrator, or flashing light, to provide visual and mechanical alarm signal for this application, or a digital display unit comprising individual LEDs or bar LED display to provide visual alarm signal;
wherein the RF/microwave radiation detection channel further comprising;
a RF/microwave radiation sensor;
a RF/microwave signal processor;
a comparator, andan analog display unit comprising a meter, or bar LED display, or vibrator, or flashing light, to provide visual and mechanical alarm signal for this application, or a digital display unit comprising individual LEDs or bar LED display to provide visual alarm signal; and

Abstract
An apparatus detects DC magnetic field, AC magnetic and electrical fields, and high frequency/microwave radiation, and alarms when the field strength is beyond the safety threshold. The threshold was set up based on pacemaker and other implantable device manufacturer'"'"'s specifications and left enough safety margins to give early warning before the sources actually start interfering with the implanted devices.
