â€˜digital SPIN', or dSPIN, combines the digital
control, analog measurement and power electronic circuitry for controlling
stepper motors using ST's BCD fabrication process. It is the first device in
ST's new dSPIN family of monolithic
motor-control ICs. Implementing the motor-control calculations in hardware
simplifies software design by requiring only acceleration, deceleration, speed
and target position commands from the application microcontroller. This frees
microcontroller resources to support other differentiating features.
voltage-mode approach allows full digital control, feeding the motor phases
with an accurate sinusoidal waveform and resulting in position resolution of
128 microsteps per step. Other advantages include reduced resonances,
mechanical noise and low-speed vibration, as well as reduced speed and torque
ripple at low speeds.
has taken advantage of analog integration using its advanced BCD process to
implement rich protection features on the chip. These include over-temperature
protection, low bus voltage protection, non-dissipative over-current protection
and motor stall detection.

BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
