Disruptions spurred by the Japan earthquake and tsunami caused shipments of crystals to be delayed by four weeks in April. The average lead time for megahertz and kilohertz crystals rose to 12 weeks in April, up 50 percent from eight weeks in March. Unusually long lead times can lead to delivery delays and short supplies of electronic products. Delivery delays, in turn, are … [Read more...]
High Power Electromagnetic (HPEM) Threats to the Smart Grid
This paper is focused on the threats and impacts of High Power Electromagnetic (HPEM) environments on the U.S. Power Grid and further introduces the implications of making the power grid “smarter” through the introduction of additional electronics. These Smart Grid electronics may introduce additional vulnerabilities if the grid is exposed to the high power EM threats of … [Read more...]

iPad 2’s Compass Susceptible to EMI
A number of iPad 2’s parts are in short supply after the Japanese earthquake. One such component, the tablet computer’s compass, cannot be replaced with other units because it is compasses are susceptible to EMI. Also, the iPad 2's compass works in close coordination with the tablet's accelerometer and gyroscope. This makes it impossible to simply replace one manufacturer's … [Read more...]

Japan Disaster Affecting Tech Supply
Japan is responsible for 14 percent of global production in computers and other consumer electronics. Sixty percent of the world’s silicon wafers, used in semiconductor chips, are made in Japan. It is predicted that it could take six months before the tech supply chain returns to normal. Plants run by Toshiba, Panasonic and Sony have already been struck with damage, forcing … [Read more...]
Inflight Wi-Fi Interfering with Flight Critical Electronics
Inflight Wi-Fi and cellphone services, which transmit low power microwave radio signals within an aircraft's fuselage, has been found to be interfering withflight critical electronics. This latest finding was made by Boeing while testing inflight Wi-Fi equipment for use on its next generation 737 twin-engined aircraft. The plane maker found that a certain type of new, brighter … [Read more...]
Energy Usage Data Standard for U.S. Smart Grid
The governing board of the public-private Smart Grid Interoperability Panel (SGIP) has voted in favor of a new standard important for two-way data communications between utilities and their customers, bringing the next-generation "smart" electrical power grid a step closer to reality. The data standard was developed by the North American Energy Standards Board (NAESB) at the … [Read more...]
Bandwidth Battle Brews between Cell Phones, GPS
