MCP651/2/5 (MCP65X) are the world's first and only op amps to include mCal, an
on-chip calibration circuit that calibrates offset voltage at power-up using an
internal power on-reset detector, or based upon the state of an external
pin. The result is a low initial voltage
offset and a means to minimize drift over time and temperature, which are
extremely important for applications involving instrumentation and sensor
conditioning, because this enables extremely precise measurements. The on-board
calibration circuitry within the MCP65x eliminates the need for external
calibrating components and minimizes software complexity by offering a simple,
single-pin hardware control of the calibration. Relative to a
chopper-stabilized or auto-zeroed amplifier, mCal Technology can provide a more
cost-effective solution and does not have the switching noise inherent to
chopper-stabilized amplifiers. mCal Technology offers a cost-effective, easy-to-use
alternative by eliminating the need for external calibration and can provide a
more cost-effective solution relative to a self-correcting architecture.
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.
