The VersaMax™ Nano Controller from GE Fanuc Automation, http://gefanuc.com/products/controllers,
targets high-volume applications with cost, space, and fast-processing-speed
constraints. "Its $180 list price makes it a more flexible option for engineers
designing counter-, timer-, and relay-based control systems," says Product
Manager Bill Black. With only 10 I/O points, Nano targets applications that need
powerful control, but not high I/O counts. The compact (75- x 80- x 47-mm) PLC
includes 2K words of memory, PID, floating-point math, subroutines, and serial
read/write commands. It supports up to two high-speed counters (10 kHz) and has
three PWM/pulse train outputs (5 kHz). Standard RS-232 communication can be used
for SNP Slave, Modbus RTU Slave, or Serial In/Out commands. Plus, the new
VersaMax SE Module connects Micro and Nano controllers to Ethernet so users can
solicit and send information, upload/download programs, and monitor and control
devices over Ethernet.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
