The TX810 is the industry's first integrated, eight-channel,
transmit/receive (T/R) switch for ultrasound systems. The device integrates a
protection diode bridge and clamp diodes for each of its eight channels to
prevent the high-voltage pulses of the transmitter from damaging the receive
electronics of the ultrasound system. The device addresses designers' need to
build smaller portable ultrasound systems, while speeding time to market. In
addition, the TX810 saves more than 50 percent board space over discrete
solutions in portable to mid-range ultrasound systems, and the component
reduction and easier handling brings higher reliability to designs. Texas
Instruments says it's first to market with integrated T/R switch facilitating
portability by saving over 50 percent board-space.
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.
