Designed as a stand-alone controller for moderate to high-performance applications, the Ensemble Epaq's motion control capabilities include point-to-point, linear and circular interpolation, electronic gearing, and velocity profiling. The unit's processing power and high-performance capabilities come from a 225 MHz double precision, floating-point DSP. An optional single-axis Position Synchronized Output (PSO) offers high-speed position latching capability. To simplify generating motion commands, the unit has an intuitive user interface and does not use cryptic commands. Standard interfaces include RS-232, joystick, Ethernet and USB 2.0 ports. Each axis of the Ensemble Epaq I/O has a 16-bit ±10V dc analog input, dedicated home marker input, over-travel limits, Hall inputs for motor commutation, and Estop input. Targeting applications from basic laboratory experimentation and general purpose positioning to advanced OEM systems, the unit drives and controls linear or rotary brushless, dc brush servo, and microstepping motors.
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.
