A smartphone generates much less mobile data traffic than a laptop with a data card, but phones impose a load on the network which is much larger than anticipated, a study showed on Wednesday. A boom in mobile data traffic – boosted by laptops and smartphones – is putting unprecedented
W. L. Gore has developed a 10 meter SFP+ copper cable assembly that is fully compliant with the SFF-8431 Revision 4.1 specification. The SFP+ (Small Form-factor Pluggable) offering purportedly goes 3 to 5 meters longer than other passive options.
The thick film MIL-PRF-55342 R level resistors from TT electronics IRC are qualified from 1 O to 10 MO for the 1206 style, and 1 O to 15 MO for the 2010 and 2512 package sizes. The TMC Series includes power ratings of 250mW for the 1206 chip, 800 mW for the 2010 resistor
The ispClock 5400D device from Lattice Semiconductor & the SG-710 CMOS oscillator from Epson Toyocom is intended for SERDES applications such as XAUI or SDI Video. The devices have a low phase noise on-chip PLL that generates frequencies greater than 150 MHz.
The majority of motor-control designers are consistently and continuously looking for methods to improve efficiency while reducing system cost. These are the two main factors that are driving the efforts to improve existing motor designs and motor-control techniques. A good example of this trend is the Permanent Magnet Synchronous Motor (PMSM).
Scientists in Japan said they have uncovered evidence that shows it may be possible to delay or prevent heart failure in humans. Tetsuo Shioi, lead researcher and assistant professor of medicine at Kyoto University Graduate School of Medicine in Kyoto, and his team described how they managed to suppress a variety of the P13K gene in a group of elderly mice.
Indian Kashmir's glaciers are melting fast because of rising temperatures, threatening the water supply of millions of people in the Himalayan region, a new study by Indian scientists says. The study by Kashmir University's geology and geophysics department blamed the effect on climate change
Earlier, we reported that global investments in renewable energy had dipped 40% from 2008-09—thus, the following comes as welcome news. George Soros has decided to invest $1 billion of his own money into “green technologies.” Soros issued a clear directive on how his money ought to be spent
While scientists are finding ways to make batteries smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
In its search for fugitives, the FBI has begun using facial-recognition technology on millions of motorists, comparing driver's license photos with pictures of convicts in a high-tech analysis of chin widths and nose sizes. The project in North Carolina has already helped nab at least one suspect.
Tektronix, Inc announced the MSO70000 Series of Mixed Signal Oscilloscopes. The instruments have up to 20 channels of measurement capture (four analog and 16 digital) with analog bandwidth ranging from 4 GHz to 20 GHz and 80 ps digital channel timing resolution. The MSO70000 Series combines
Gigahertz-Optik’s hand-held BTS256-LED is designed to measure luminous flux or illuminance, color data and spectral distribution of pc board mounted LEDs, discrete LEDs within a module, miniature lamps, endoscopes and any narrow beam emitting light source. Larger size light sources can
GlobTek’s GT-91085-1548 48V power over Ethernet (PoE) active injector offers a fully IEEE compliant solution for remote powering of wireless LAN (WLAN) access points, voice over IP phones and network security cameras. The active injector has automatic detection and
Containing Swept Quartz crystals, the Model 1118 family of clock oscillators from Vectron International purportedly eliminates the potential for significant frequency shifts as a result of impurities.
Crystek's CPLL58-4240-4240 PLL/Synthesizer operates at 4240 MHz with a typical Step Size of 2500 KHz. The PLL/Synthesizer is programmed using a standard three line interface
