This motion control card is the first to communicate and supply power at the same time using an Ethernet bus, working at distances up to several thousand yards. It has an integrated Web server, using Ethernet protocol to control 10-48V dc brush motors. It can work with protocols like http and TCP-IP that are already embedded in most major computer operating systems, plus it runs from an Ethernet cable at powers up to 15W (card + motor), using the latest IEEE 802.3af standards. An external power supply allows the card to work at up to 70W continuous and 140W max. Its embedded RISC processor has a 4-quadrant, 32-bit RISC PID regulator, refreshing power regulation of to 4KHz with a sampling rate of 20-2,000Hz, so it can control brushed dc motors by position and speed, and position with a trapezoidal speed profile. They come in a variety of available modes.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Ear-based heart-rate monitoring gained momentum recently, as sensor maker Valencell Inc. announced it has licensed its biometric earpiece technology to Samsung Electronics Co. Ltd for use in so-called “hearable devices.”
