(http://rbi.ims.ca/4917-54). Although only 10 × 10 × 12 inches, this digitally-controlled subwoofer delivers 2000W of dynamic power with a fraction of the distortion of competitive systems. A digital accelerometer in the unit measures the movement of the subwoofer cone and a DSP controller compares this movement to the input signal at a rate of 15,800 times per second to make corrections and keep the cone's motion as close as possible to the source input. To achieve typical distortion rates well below 0.5 percent, Velodyne Acoustics' engineers chose Texas Instruments' TMS320C2000 controller for its DSP performance and highly integrated MCU-like peripherals.

A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
