Autonomous/Driver-Assisted Vehicles

Autonomous/Driver-Assisted Vehicles-Testing Galore!

Autonomous/Driver-Assisted Vehicles-Testing Galore!  Many of us feel that machines can't replace people.  This is especially true of the automotive driver seat!  People do not want to put their lives in the hands of a machine.  We've all dislike back seat drivers, but the thought of no driver is even scarier!  The reality of Partially Autonomous/Driver-Assisted vehicles is here.  Many cars already have AEB (Automatic Emergency Braking) systems.  My car has LKA (Lane Keeping Assist) and it's two years old!  I...
EMC Pre-Compliance Testing

EMC Pre-Compliance Testing-Home or Away?

EMC Pre-Compliance Testing-Home or Away?  EMC Testing is necessary during product development.  Pre-Compliance EMC Testing during development is more important.  Pre-Compliance EMC Testing prepares your device for Final EMC Compliance Testing!  Equipment for in house Pre-Compliance EMC testing can be purchased or rented.  Once the employees are trained in EMC testing, a "home game" is much easier all around than an "away game".  In-house testing also involves the development team, increasing their investment in product development.  Obviously, EMC Testing at...
Personal Shielding

Personal Shielding-RF/EMI Shielding!

Personal Shielding-RF/EMI Shielding!  We tend to think of RF/EMI Shielding in the electronics industry.  RF/EMI can affect the function of electronic devices.  Interference can reduce the operational efficiency of electronic devices.  Human beings are also electronic devices.  Many body systems are electronic in nature, potentially disrupted by RF/EMI.  We live in a world with ever-increasing RF/EMI.  Some of this RF/EMI is from nature.  Natural RF/EMI includes lightning, solar magnetic storms, the auroras, and the Earth's magnetic field.  The natural RF/EMI...
Conductive Metalized Textiles

Conductive Metalized Textiles-not just for Shielding!

Conductive Metalized Textiles-not just for Shielding!  When conductive textiles were first developed, Shielding was their use.  They were used to make sure car radios worked well.  RFI and EMI were blocked, eliminating static hissing!  They are still used to protect critical systems from RFI/EMI.  They are also currently used in many different ways. Conductive Metalized Textiles-not just for Shielding!  The medical sector uses conductive textiles as sensors.  Human vital signs are detected by sensors and sent to recording devices.  The human...
RF/EMI Shielding Curtain

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 to the proper recording device.  The...

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 from passage to...

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...
Shielding Fabric

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 compliance.  Every country...
Conductive Mesh Tulle

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 matter.   Conductive mesh...
RFI Interference

Shielding lowers Interference-Devices work Better!

Shielding lowers Interference-Devices work Better.  We all know what interference is like in an office situation.  While concentrating on an important job, someone disrupts your concentration.  The interference comes from a coworker who is working with you.  Frustration sets in, you can't get back "into the zone".   You know you aren't performing your best work.  The same thing can happen to devices in a shared electrical environment.  All devices are trying to work but can't function well.   In the workplace...
