For the first time, researchers at North Carolina State University have demonstrated that microscopic "two-faced" spheres whose halves are physically or chemically different - so-called Janus particles - will move like stealthy submarines when an alternating electrical field is applied to liquid surrounding the particles.A paper describing the research, published in the Feb.

In an effort to make typing on the iPhone more familiar, the University of Glasgow has unveiled a hack that provides vibration feedback when a virtual key is pressed, simulating the effect of typing on a real keyboard. The patch enables what the University calls haptic feedback, which researchers say can help improve typing speeds, while simultane
Filed under: Displays , HDTV , Home Entertainment While we were just able to take a look at Sony's BRAVIA VPL-VW70 SXRD at CEDIA , it appears that the company is showing Europe a little love with the awfully similar VPL-VW80. The Full HD beamer includes High Frame Rate SXRD panels, a 100Hz Motionflow Dark Frame Insertion system, the BRAVIA ENGINE 2 processing tech and a
Supporting various configurable test fixtures, Model GAO2782 can measure frequency ranges of 75 kHz to 30 MHz with resolution of 100 Hz. With 5 mV to 2 V signal level range, it has 0.01 W to 10 MW impedance measurement range, 0.1 pF to 100 µF range for capacitance, and 0.1 nH to 100 mH for inductance. Other measurable parameters include dissipation factor, quality factor, conductance, reactance,
