Victor, NY - October 13, 2009 – New Scale
Technologies today announced the first shipment of custom auto focus
modules that install directly on board-mounted cameras and accept
standard threaded lens assemblies. This compact lens motion module
uses New Scale's tiny SQUIGGLE® motor, TRACKER™ position sensor, and
integrated electronics providing extremely compact, high resolution
closed-loop control. These components are combined with precise
mechanical guidance in a robust polymer housing only slightly larger
than the optical lens assembly.
"We are now providing plug-and-play motorized focus solutions that
can be adapted to any PCB-mounted camera," stated Ralph Weber,
product manager at New Scale. "This new product platform is fast,
precise and easy to integrate. We enable our customers to create
high-performance board camera solutions in less time and at lower cost."
This lens motion module can be easily and rapidly customized to
fit almost any board camera using parametric computer design
tools. The customer must define the PCB mechanical mounting
interface, dimensions of the threaded lens assembly, and the macro
and infinity image plane locations. The drive electronics are
provided on a separate circuit board that accepts USB, analog and
I2C motion commands. As an option, New Scale can provide this chip
set for direct integration on the camera printed circuit board.

About New Scale Technologies
New Scale Technologies (www.newscaletech.com) creates disruptively small
motion systems based on our patented piezoelectric SQUIGGLE® motor, the world’s
smallest linear motor, and TRACKER™ position sensor. The ultrasonic SQUIGGLE motor
is smaller, more precise, less expensive, more robust and more power-efficient
than other micro motors. The TRACKER position sensor integrates a magnetic sensor
with on-chip digital encoder, for smaller size and higher resolution than miniature
optical encoders. We create complete motion systems integrating micro motor and sensor
technology with supporting electronics (ASICs) developed with our partner
austriamicrosystems.
New Scale’s micro motors, encoders and micro-actuator modules enable design engineers
to create smaller products including mobile phone cameras, electronic locks and
intelligent fasteners, nano-scale fluid control including lab-on-a-chip systems,
medical devices including miniature drug pumps and endoscopes, optics and
imaging systems, automotive modules, lasers, aerospace and defense systems,
cryogenic and MRI-compatible instruments, and consumer electronics including
micro fuel cells.
