Application Notes
How our technology can be applied in various applications. We
include block diagrams and basic performance results pertaining
to that application.
- Auto
focus for picoprojectors using a SQUIGGLE RV micro
motor, TRACKER position sensor, and an ultrasonic
rangefinder
- M3-F custom focus modules mount directly on board cameras
over a CCD or CMOS image sensor, adding precision
focus to OEM cameras while preserving their compact size
advantage. The focus module is only slightly larger than a
standard lens assembly (M6 to M12 supported).
It provides millimeters of lens motion with 0.5 μm
resolution.
- Tiny 3x optical zoom
module for higher-resolution imaging in smaller devices. A
reference design for a tiny 3x zoom module demonstrates New
Scale’s ability to design and produce micro modules that allow
OEMs to embed higher-resolution imaging in smaller devices. With
integrated SQUIGGLE micro motors and TRACKER position sensors,
the module offers 6 mm of travel and 0.5 µm closed-loop position
resolution in a thin 6.5 x 13 x 23 mm module.
- Miniature position
sensor improves autofocus and zoom in digital still cameras.
TRACKER position sensors improve focus and zoom in digital still
cameras, video cameras and similar products. Used to upgrade
existing open-loop stepper motor systems or replace optical
encoders, this sensor reduces power use and enables faster, more
precise focus and/or zoom. This application note describes the
benefits and use of TRACKER position sensors in miniature camera
lens systems.
- Custom
FPC connectors for miniaturizing SQUIGGLE motor connections.
SQUIGGLE motors, the world’s smallest linear motors, are now
routinely integrated into motion systems by OEM customers all
over the world. The challenge is always to minimize the total
package size while accommodating such system components as the
drive electronics, microprocessors, and perhaps the worst
offenders of all, connectors. This app note provides advice for
minimizing the size of SQUIGGLE motor connectors.
- Using SQUIGGLE motors in
miniature closed-loop motion systems.
New Scale has created a number of tiny, high-resolution
closed-loop systems with SQUIGGLE motors incorporating TRACKER
position sensors and other position feedback devices. We excel
at creating application-specific
closed-loop miniature motion systems for our OEM customers. This
application note provides an overview of SQUIGGLE motors in
closed-loop systems.

How to integrate our technology, regardless of the
application. Includes information on motor mounting, drivers,
etc.

M3-F focus module developer's kit compatibility. How to
check your lens and imager compatibility before ordering a
DK-M3-F developer's kit.

Quick tips for implementing SQUIGGLE motors. With the
availability of the new easy-mount metal housing along with the
drive ASIC, integrating SQUIGGLE motion solutions has never been
easier. As you design your motion system and integrate SQUIGGLE
motors into your product, there are a few key design practices
to follow. This design note lists six common mistakes and how to
prevent them.
- How to
mount the SQL-RV-1.8 piezoelectric SQUIGGLE micro motor. A
stainless steel housing facilitates mounting and mechanical
integration of New Scale’s SQL-RV-1.8 Series SQUIGGLE motor, the
world's smallest linear micro motor, and ensures optimal motor
performance in miniature OEM products. This design note presents
several suggested mounting techniques. (Also applies to SQL-1.8
micro motors.)
- Choosing miniature
position sensors for SQUIGGLE motors.
SQUIGGLE motors are open-loop devices. While the motor can move
in very precise increments, the distance moved in response to a
single drive signal pulse depends on the load and the motor’s
internal friction. Any variation in these parameters along the
length of travel will affect the motor speed. If you need to
know the precise speed or position of the motor, you need to
create a closed-loop system incorporating feedback from a
position sensor. This design note presents several options,
including the TRACKER position sensor, and their design
trade-offs.
