RF/EMI Shielded Curtains-Privacy and Separation!
RF/EMI Shielded Curtains-Privacy and Separation! In our lives, we use curtains for privacy, separation, and protection. RFI/EMI Shielded Curtains are used in the same way. RF Shielded curtains are made of conductive metalized textiles. These curtains block the passage of RF and EMI waves. One of the major uses of these curtains is in hospital telemetry areas. They effectively isolate the beds in a "shielded room". This assures that the proper information is transferred...

RF/EMI Shielded Garments-Wearable Protection!
RF/EMI Shielded Garments-Wearable Protection! Our environment is full of Electromagnetic Radiation (EMR). Many of the sources of EMR "natural" and have always been present. The sun, atmospheric auroras, and the earth itself have electromagnetic fields. We are constantly exposed to these low-level electromagnetic fields. RF/EMI is a problem in electronic devices, decreasing performance. Electronic devices are shielded from RF/EMI using shielding materials. The shielding materials in electronic devices are often conductive metalized textiles. The metalized textiles block RF/EMI...

Ideas to Reality-Product Design and Development!
Ideas to Reality-Product Design and Development! Products don't just appear; they evolve from great ideas! The path from idea to final product has many steps. The first step is the idea, the cornerstone of the product. A person conceives a better way to accomplish a task. The challenge is to make the idea become a reality. In many cases, the inventor is only a "dreamer". He has no idea of how to make his "dream" a reality. Help often comes...

Electromagnetic Compatibility-when devices work smoothly Together!
Electromagnetic Compatibility-when devices work smoothly Together! Devices are like people, they work best when they're compatible. Electronic devices work best when they don't interfere with each other. Electronic devices can be interfered with in several ways. They can be "distracted" by RF interference emitted by nearby devices. This distraction is similar to a co-worker who is always talking. The background "noise" keeps work quality below its potential best. Devices that can be "distracted" are called "susceptible". The answer to susceptibility...

RF/EMI Shielding-the Key to EMC!
RF/EMI Shielding-the Key to EMC! Electromagnetic Compatibility Standards must be met prior to marketing devices. The device must perform well in a shared electromagnetic environment. It must not disrupt the performance of other nearby devices. It must not be disrupted by its environmental coworkers. The "potential disruption" is caused by RF/EMI outside of acceptable standards. In the US, the FCC determines these standards. In Canada, Industry Canada determines the standards. Europe requires the "CE" mark that represents...

What is Conductive Mesh-how is it used?
What is Conductive Mesh-how is it used? Conductive Mesh is a knitted metal plated fabric with pores. The fabric is Nylon 6, Nylon 6.6 or polyester. The pore size varies, pores can be big or small. If they are small, the mesh can be used for filtered ventilation. Conductive mesh vents are often used in the ventilation systems of our RF Shielded Testing Enclosures. Conductive meshes are useful in face masks to filter the air of particulate...

Berry Amendment vs BAA-what’s the difference?
Berry Amendment vs BAA-what's the difference? The Berry Amendment was passed in 1941. The Berry Amendment applies only to the Department of Defense (DoD). It requires that DoD funds are spent on US manufactured items. This practice protects the US industrial market in times of war. Primarily, it covers tools, food, and textiles for use at home and abroad in military operations. The Berry Amendment is very specific in its coverage. The Berry Amendment requires 100% domestic content of covered...

Wrapped Yarns-Three New Options!
Wrapped Yarns-Three New Options! Shieldex and Lederer GmbH are developing three new products. Three types of conductive wrapped yarns are under development. These products are: Wrapped Yarn dyed: Silver plated yarns cannot be dyed. Color can now be added by wrapping the dyed yarn with silver plated yarn. The silver plated yarn is not directly affected by the dyed yarn. This allows the plated yarn to maintain its electrical and thermal conductive properties. Wrapped Yarn Stretched: Using a very stretchable yarn...
