Electromagnetic Hypersensitivity

Electromagnetic Hypersensitivity-help is hard to find, but it’s Available!

Electromagnetic Hypersensitivity-help is hard to find, but it's available!  For years, some individuals have reported a wide range of non-specific health problems that they attribute to low-level exposure to electromagnetic fields, (EMF).  The symptoms include:  headaches, body pain, lethargy, tinnitus (ringing in the ears), nausea, burning sensation, heart arrhythmia, and anxiety.  The World Health Organization (WHO) said that "no adverse health effects have been established as being caused by mobile phone use".  The WHO, along with the International Agency...
Eliminate Crosstalk

Cable Sleeves Eliminate “RFI Crosstalk”, keeping Data Secure!

Cable Sleeves Eliminate "crosstalk", keeping Data Secure.  Cables are the way that information is transferred between computers.  Crosstalk refers to electromagnetic interference from one unshielded twisted wire pair  to another unshielded twisted wire pair travelling parallel with each other.  Electric signals passing through wires create magnetic fields that interact with each other.  A wire can be either a "transmitter" or a "receiver" of electromagnetic noise.  Both forms of interference/noise affect the data quality negatively.  There are two ways of stopping...
RF Shielded EMC Testing Enclosure

Portable RF Shielded Enclosures are Excellent Testing Options!

Portable RF Shielded Enclosures are Excellent EMC Testing Options!  These Enclosures are used in Pre-Compliance testing of new electronic equipment in the developmental stage.  They provide the perfect ambient-free environment necessary for this type of testing due to the "Faraday Cage Effect".  The metalized conductive textiles used in making these enclosures block unwanted electromagnetic fields and waves inside of the enclosure.  The Device Under Testing (DUT) can then be operated in a "clean RF environment" to determine if normal...
Monofil Braided Tube

What is Braided Tube, What is Braided Tube used for?

What is Monofil Braided Tube? Shieldex® Monofil Braided Tube is essentially a "sleeve" used to enclose data cables.  Data lines are fed through this flexible sleeve, made of woven individual Polyamide threads, with each thread having been individually coated with silver, which helps to protect them from severe kinks, bends, and abrasion. This lightweight flexible sleeve also provides a protected "electronically shielded environment" for the data cables and the information that is carried through them.  This "silver braided cable sleeve" is...

What are Faraday Cages and How are they Used?

Faraday Cages are enclosures first researched by Benjamin Franklin in 1755, but mostly attributed to the work done by Michael Faraday in 1836.  Essentially, a Faraday Shield is an enclosure made of a continuous covering of walls, ceilings, and floors by a conductive metal that is used to completely block Electromagnetic Fields from entering the inside of the enclosure by spreading the current over the outside of the enclosure.  In contrast, a Faraday Cage, which involves the use of...

Compliance Test Tension? An RF Shielded Enclosure by V Technical Textiles, Inc. can Ease the Stress!

We all know that final EMI Compliance Testing can be a tense time.  Time has been invested in development, design, prototyping, and now it is time to find out if your device is compliant with applicable ElectroMagnetic Compliance (EMC) standards.  You drive the three hour trip to the testing site on your appointed day.  Of course, the line has formed and "they're running a little behind today", so you wait for your turn.  You hand your device over to...

Size Problem? Large or Small, VTT can Help with your EMI Testing Needs!

Electronic devices come in many sizes, whether your device is the size of a cubesat, an automobile, military vehicle, or a spacecraft, V Technical Textiles can help you with your EMI Testing needs by providing you with one of our portable RF Shielded Testing Enclosures, specially designed for your testing needs. EMI testing follows two basic tests that determine if a device is fit to work in an environment with several types of electronic devices in it. The first test...

“Hardening Structures”-Protecting our Country’s Vital Electronics-Based Systems!

ElectroMagnetic Pulses (EMPs), transient electromagnetic disturbances, evoke the Orwellian thoughts of nuclear explosions that are capable of short-circuiting a wide range of electronic equipment, including computers, satellites, radios, radar receivers, and even traffic lights, plunging the world into the "electronic dark ages".  Though a nuclear weapon is the most commonly thought of cause of an EMP, they can also be caused by solar flares, a close lightning strike, or a massive powerline short circuit.  The damage to electrical equipment...
Pre Compliance Testing

Portable RF Shielded Enclosures Provided Work from Home Applications During Covid-19

When Covid-19 hit North America in March, it closed down a lot of our businesses, but many businesses and individuals were able to continue to do work from home or other remote locations during the quarantine/social distancing period of this pandemic.  The "Work From Home" #wfh group, were often able to continue their work with the use of RF Shielded Enclosures and pouches. One didn't need to be in the electronics development business to benefit from these enclosures.  Government and...

The Constant Increase of Electronic Devices makes the Shielding Industry Very Important in Achieving EMC!

We have more electronic devices than ever before in this world, each of them adding to the invisible cloud of E-Smog that surrounds us all.  More of these devices are being developed all of the time, with the development in cellular infrastructure for the 5G and 6G communications systems....yes, I said 6G!!!  That doesn't include the aerospace and automotive industries as today's aircrafts and automobiles are essentially controlled and driven with the aid of complex electronic devices and the...
