MIT claims 24/7 solar power Design How-To 7/31/2008 3 comments Researchers at the Massachusetts Institute of Technology have combined a liquid catalyst with photovoltaic cells to achieve what they claim is a solar energy system that could generate electricity around the clock.
Microscope-on-a-chip debuts Product News 7/29/2008 Post a comment Today's bulky, expensive microscopes could be come smaller and cheaper after researchers found a way to combine pinhole optics, microfluidics and a charge-coupled device to assemble a working microscope on a single chip.
Lasers need lenses no more News & Analysis 7/29/2008 1 comment Researchers have demonstrated a plasmonic collimator that utilizes grooves etched directly into the semiconductor laser facet. The technique could eliminate costly, bulky lenses.
Solar cars racing across North America News & Analysis 7/15/2008 Post a comment Start you solar engines: The North American Solar Challenge car race from Dallas to Calgary, Canada--over 2,400 miles in 10 days--is under way. So far the University of Michigan's Continuum entry is leading, with Principia College's Ra-7 16 minutes behind.
Solar thermal technology heats up Design How-To 7/15/2008 3 comments Solar thermal technology that attempts to harness the efficient phase change from water to steam is emerging as the preferred alternative energy technology in the race to replace fossil fuels with sustainable energy sources, experts agree.
Sun angle sensor simplifies integration Design How-To 7/3/2008 Post a comment Sensors for the measurement of the angle of incident light are required for many applications in vehicles, with air conditioning control being the most important. Available systems, however, can only be accommodated with great difficulty due to limited available space. In addition, they represent a source of optical irritation. The single-chip ASIC-based solution described avoids all these problems.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
