RF Shielded Curtains create Security and Isolation

RF Shielded Curtains create Security and Isolation!

RF Shielded Curtains create Security and Isolation!  Today's electronic world relies heavily on wireless transmission of  information.  Wireless access to information makes transactions and transmission easy.  Unfortunately, wireless access sometimes allows access to private or important information when it shouldn't be!  Examples of data security include credit card information, passwords stored on wireless devices, even vital signs in a telemetry unit in a hospital to make sure that this private information is secure and directed to the proper location.  Practical...
EMC-It's all about the Environment!

EMC-It’s all about the Environment!

EMC-It's all about the Environment!  It's terrific when people work smoothly together.  They focus on the job at hand and accomplish their tasks efficiently.  You feel their compatibility in the easy flow of their work!  It's the same way with electric components working together in a shared environment.  Electronic devices emit electromagnetic interference naturally while working.  These natural emissions can negatively affect the overall functioning of the device.  EMC Final Compliance Testing is required for all electronic devices before marketing...
Electronic Devices plus Great Shielding=EMC!

Electronic Devices plus Great Shielding-EMC!

Electronic Devices plus Great Shielding-EMC!  Electronic devices are great things, making so many tasks easier and more enjoyable for us!  Sadly, they also create EMI and RFI emissions naturally.  Unfortunately, some of these emissions affect other devices working in their shared electromagnetic environment adversely.  Consider the analogy of an office, one employee talks loudly and makes it hard for the other employees to concentrate at their highest level.  The talking employee is an "emitter" of EMI/RFI and the other employees...
Personal/Home Shielding reduces EMI Exposure!

Personal/Home Shielding reduces EMI Exposure!

Personal/Home Shielding reduces EMI Exposure!  In today's wireless world, we endure constant exposure to RF waves.  Though there is no absolute proof of health risks due to RF wave exposure, there is certainly concern regarding exposure.  EHS (Electromagnetic HyperSensitivity), the name given to EMI sensitivity, involves nervous system symptoms.   Symptoms include headaches, fatigue, stress, sleep disturbances, and skin irritation among many others.   Many sufferers of EHS claim that their symptoms decline when they shield themselves from RF/EMI exposure.  Personal Shielding...
RF Shielded Pouches-Privacy Bags!

Digital Device Security-RF Shielded Pouches!

Digital Device Security-RF Shielded Pouches!  Our digital devices are wonderful, they allow us easy access to our private information all the time!  We don't leave home without them, and always have them nearby.  Unfortunately, this private information is also accessible by nefarious others.  In today's world, there are people who make a living by illegally wirelessly accessing personal digital devices.  They access the information using unsecure Wi-Fi connections such as internet cafes or guest connections in restaurants and hotels.  It...
Metallized Textiles

Metalized Textiles-What are their Uses?

Metalized Textiles-What are their Uses?  Metalized textiles were first used in various Shielding Applications.  I can remember when an automobile FM radio mainly played static!  Metalized textiles played a major role in protecting the radio from RFI from the other electronic components in the vehicle.  The antenna brought in shielded clean signals to the RF shielded radio which were sent out to the speakers, allowing the music to be heard as it was meant to be heard.  The RF shielding...

Conductive Fabrics-Great Shielding Material!

Conductive Fabrics-Great Shielding Material!  Shielding materials are usually needed in electronic devices to protect the devices from EMI/RFI which can adversely affect their performance.  The more conductive the Fabric is, the better its shielding characteristics are.  Obviously, fabric is typically lightweight and flexible, making it great for shielding in tight quarters.  Engineers also love the lightweight, as products today are smaller and more portable than ever before.  Lightweight is also important in the automotive, aerospace, military, and law enforcement markets,...
RFI/ EMI Shielding Conductive Textiles

RFI/EMI Shielding-What is it?

RFI/EMI Shielding-What is it?  RFI Shielding is essentially blocking radiofrequency electromagnetic signals in the radio frequency band of the electromagnetic spectrum.  Left unchecked, these signals can disrupt the electrical circuits from working properly.  Basically, RFI shielding involves the placement of barriers made of conductive and magnetic materials around the device, allowing it to function optimally.  The name "shielding" means completely isolating the susceptible parts from the source of the RFI.  The Effectiveness of the shielding depends on properties of the...
Testing Situations-Prepare for them!

Testing Situations-Prepare for them!

Testing Situations-Prepare for them!  You remember it from school, from the first day of class, you knew that there would be a "Final Test".  The "Final" would determine whether you would move on to the next level, or whether you would have to repeat the test!  Preparation for the final was very important.  A parallel situation to the "Final Test" exists when developing a new electronic product for marketing.  Commencing with development is the first step for the device toward...
SCIF Construction-are Standards Meetable?

SCIF Construction-are Standards Meetable?

SCIF Construction-are Standards Meetable?  Sensitive Compartmented Information Facilities (SCIFs) must be built to very strict standards!  SCIF security requirements and construction specs are based on many factors.  Included in the list are facility purpose, surveillance risk, and physical location of the SCIF.  Sensitive information exchanges, sound damping, and Personnel security are also important parts of the equation.  The final assessment will be made by Accrediting Officer (AO) and Site Security Manager (SSM), determining technical measures for each SCIF application.  The...
