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! 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...

Cotton and Silver Together make Great Clothing!
Cotton and Silver Together make Great Clothing! We all know cotton is a natural fabric, planted in the spring and harvested in the fall. Cotton is very versatile; it can be woven in a variety of thicknesses to change its feel. It is incredibly strong, which helps your clothing last longer. Incredibly, cotton gets stronger when it is wet, allowing washing, losing dirt without losing its shape! Cotton is non-allergenic, making it terrific for those with sensitive...

EMC Compliance Test-Prepare your Product!
EMC Compliance Test-Prepare your Product! Every electronic device must pass EMC Compliance tests in order to be marketed. Preparing your product for this should be done from the start of the product's development until it is complete. The best way to be ready for this test is to test the device early and often during product development. Running an EMC Pre Compliance test at each crucial step allows discovery and correction of issues along the way. Obviously, this stepwise process...

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. ...

Face Masks-Keep them Handy!
Face Masks-Keep them Handy! Well into the third year of the pandemic, we're all ready to put our face masks away for a while! This pandemic really caught us by surprise and changed the traditional design of face masks. The Centers for Disease Control and Prevention state that cloth masks aren't as effective against coronavirus as surgical masks and respirators. The difference is in the filtration capability. Loosely woven cloth provides the least protection, layered finely woven masks are better. ...

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,...
