EMI and EMC testing is being conducted at Orbital Science Corporation in Gilbert, Ariz., to validate that while the Landsat Data Continuity Mission Observatory is in space, all components will function together efficiently. After EMI/EMC testing is finished successfully, the observatory will be prepared for mechanical tests next month to ensure it will survive the launch … [Read more...]
EU Issues EMC Regulations for Olympics
The Office of Communications for the European Union has made EMC-related regulations for the London 2012 Olympics. The regulations, titled the "Wireless Telegraphy (Control of Interference from Apparatus) London Olympic Games Regulations 2012," seek to avoid electromagnetic interference with wireless communications during the events. Any item that may cause EMI must operate … [Read more...]
Narrowband and Broadband Signals
As I indicated in the previous post, this discussion begins examining signal characteristics from an electromagnetic compatibility (EMC) perspective. But first, a few words to describe EMC. This is a relationship issue. We want all the equipment items to get along in peace and in harmony, but if one of them is a big source and the other is a wimpy receiver, they may not play … [Read more...]
Protecting the Earth’s Limited Resources
May marks the dawn of a new blog created by Interference Technology with emphasis on Electromagnetic Compatibility. I am honored to have been asked to serve as the blogger in this newest venture to reach out to members of the community. I have written many articles over the years and have always strived to make them purely technical, easily readable, and non commercial. This … [Read more...]
System Uses EM Waves to Deliver Wireless Power through the Air
At the recent TED Global Conference in Oxford, UK, a US-based technology firm, WiTricity, demonstrated a system that delivers electricity through the air to power laptops, cell phones, and other electrical devices. This new system is based on the work of Professor Marin Soljacic, a physicist at the Massachusetts Institute of Technology. The concept of sending power wirelessly … [Read more...]
