Scale Technologies' new M3 micro actuator
module is smaller, more precise and easier to integrate than traditional
electromagnetic motor systems. Each module is a complete closed-loop motion
control system with 0.5 micron position resolution in a footprint of 12x30 mm
or smaller, and contains a patented Squiggle piezoelectric micro motor that
runs on 3V without voltage boost (compared to 40V for other piezo motors); a
position sensor; drive ASIC and microprocessor for onboard closed-loop PID
control. This combination of features means that no external control board is
necessary. Modules have 3.3V input voltage and low power consumption for long
battery life in handheld devices.
With
no external controller, electrical integration can be accomplished by sending
high-level ASCII motion commands to the M3 module via a standard serial
interface (I2C or SPI). Breakthroughs in this model include a drive ASIC with control
and performance optimization functions on the chip and a miniature non-contact
position sensor. M3-F focus modules are used in compact cameras for machine
vision and biometric imaging.
Mechanical
integration is customized to the application and possibilities include
integrating a lens within the module or pushing a lever external to the module.
M3-L linear actuators provide linear motion for applications such as tunable RF
filters, photonic tuning devices, optical instrumentation, precision hand-held
devices, aerospace controls and biomedical systems.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
