However, Chevy says the suspension is not due to poor sales; rather, it is so GM can concentrate on retooling the new Chevy … [Read more...]
Charge Your Cell Phone with Yourself
A professor at Wakeforest University’s Centre for Nanotechnology and Molecular Materials has developed a system that allows users to charge their own cell phones with their body heat. The "Power Felt" allows phones to remain charged up to 20 percent longer using body heat as electricity to charge the phone. “I have an excess of electrons on one side, and a depletion of excess … [Read more...]
Health Concerns Over Electromagnetic Radiation in India
India's Department of Telecommunications has issued new rules for radiation emissions from towers, effective Sept. 1. Mobile operators in India said they have taken proactive steps to comply with the new rules of reduced radiation emission - reducing levels by 10 percent. Current radiation levels of 4,500 milliwatts per square meter must be lowered to 450 milliwatts per … [Read more...]
New Model of DC Power Source
B&K Precision has introduced model 1747 - its latest dual range DC power source. The model delivers up to 350 W of power with constant voltage (CV) and constant current (CC) modes. Model 1747 can output either higher voltage at a lower current range (0-60V, 5A), or higher current at a lower voltage range (0-35V, 10A) - suitable for uses in electronics manufacturing, service … [Read more...]
AT&T Disables Tower Frequencies after Emergency Communications Disrupted
ATT temporarily disabled a frequency emitted by 16 towers in Oakland Calif., Tuesday, Aug. 21, after the signals interfered with emergency responder radio communications. The towers caused radio failures in police cars and fire trucks when they were within a quarter to half mile radius, David Cruise, Oakland's public safety systems adviser, said. FCC confirmed the … [Read more...]
