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.

An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
