Ventilator Systems & Medical EMC Shielding Medical facilities are one of the epicenters of the Covid-19 pandemic. Their capacity to treat infected patients with life-saving equipment like medical respirators is vital. Severe Covid-19 patients can develop a  life-threatening condition called acute respiratory distress syndrome (ARDS) that requires ventilators to deliver smaller volumes of oxygen and…

EMI / RFI Shielding For Medical Device Applications Take any average-sized hospital in the U.S. and count the number of electronic devices in use. According to the World Health Organization (WHO), that number averages over 10,000. Imagine all those separate life-saving devices – magnetic resonance imaging (MRI), computed tomography (CT or CAT), Electromyography (EMG) and…

Fortunately, the chance of a direct military attack on America from a foreign country is very slim. However, as we’ve seen from 9/11 and other terrorist attacks on our soil, the chance of a smaller and more terroristic threat is still very real. One of those types of attack is from a High-Altitude Electromagnetic Pulse…

For systems to be certified to TEMPEST (Telecommunications Electronics Material Protected from Emanating Spurious Transmissions) specific test standards need to be passed such as NSA No. 94-106 for shielded enclosures and other NSA standards depending on the intended environment and operation. The TEMPEST certified telecommunications electronic enclosure needs to be a “Faraday Cage”. A Faraday…
