Getting down to business, National Instruments’ general-purpose digitizer/oscilloscope offers a 1 giga-sample per second (GS/s) real-time sampling rate on two simultaneous channels and 20 GS/s Equivalent Time-Sampling (ETS). NI chose National Semiconductor’s dual-channel ADC08D1500 1.5 GS/s analog-to-digital converter (ADC) for the module because of its performance and features. When using only one channel, the NI unit uses the ADC’s built-in interleaving mode with autocalibration to double the real-time sample rate. Key specs for the ADC include 7.25 effective number of bits (ENOBs) at an input frequency of 748 MHz and a bit error rate (BER) of 10-18.
Two different shape-shifting polymers have been announced from two different universities: Wyss Institute at Harvard University and Zhejiang University in eastern China. Both of them change their shapes when immersed in water, and the one from Wyss Institute was made with 3D-printing techniques.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
