These capacitors are available for voltages of between 400 and 800 V at 50/60 Hz. Their reactive power ranges between 5 and 30 kvar. The … [Read more...]
Proposed Federal Legislation Would Foil Felons’ Cell Phone Use
U.S. Senator Kay Bailey Hutchinson (R-TX) at left and U.S. Representative Kevin Brady (R-TX) have introduced legislation, the Safe Prisons Communications Act of 2009. The legislation would allow the Director of the Federal Bureau of Prisons, a state Governor, or a Governor’s designee (depending on whether the facility is federally or state operated) to submit a petition to the … [Read more...]
Raytheon Climate Sensor Passes EM Testing
A sensor developed by Raytheon Company to increase understanding of how aerosols affect climate has demonstrated in testing that it would neither emit nor be impacted by interference from any electromagnetic impulses it might encounter in space. Raytheon’s Aerosol Polarimetry Sensor also completed vibration testing successfully. Next, the sensor will undergo a final test … [Read more...]
