new, innovative electric field sensor. This new sensor
technology measures electric field changes without
requiring physical or resistive contact. EPIC is an award-winning, patent-protected sensor that can rapidly measure
electric potential sources such as electrophysiological
signals or spatial electric fields. The EPIC sensor simplifies
the way movement sensing, proximity non-touch switching,
or even gesture recognition signals are taken in medical
and sports instruments, toys, electric appliances, smart
lighting, gaming, and security. The electrode surface of the
detector is coated with a passivated thin dielectric for
direct application to a test surface without the need for
electrically conductive gel. By detecting changes in the
electric field, the EPIC sensor can drive a relay to act as a
simple non-touch electric switch. It can be employed in a
proximity mode or to detect specific kinds of movement as
a gesture recognition device. Since the EPIC sensor does
not need line-of-sight, it can detect movement through
solid walls and can also be used to replace — or as an
adjunct to — passive infra-red (PIR) sensors in a variety of
applications including security motion detectors.
The sensor can be integrated on a chip with other
features such as data converters, digital signal processing,
and wireless communications capability.

ELEV- 8 Quadcopter
Kit — Flying Robot
Platform
The ELEV- 8 quadcopter from Parallax is a flying robotic
platform that is lifted and propelled
by four fixed rotors. There are no
fixed wings; all of the lift is created
from the rotors. Unlike standard
helicopters, a quadcopter uses fixed-pitch blades whose rotor pitch does
not vary as the blades rotate; control
of vehicle motion is achieved by
varying the relative speed of each
rotor to change the thrust and
torque produced by each.
The quadcopter uses a HoverFly
board with a Propeller multicore
microprocessor to electronically
control stabilization of the aircraft.
The benefits to this system are a
stable platform with no mechanical
linkages for a small maneuverable
and agile aircraft. The kit provides an
inexpensive way to get involved in
the quadcopter arena. The kit
includes: frame, mounting hardware,
motors, speed controllers, propellers, and the control
board for flight stabilization (the only thing you need to
provide is the RC radio equipment and battery). The ELEV-
8 platform is large enough for outdoor flight and has
plenty of room for payload and attachments (up to 2 lbs).
Features include:
• Open under body for camera mounting options.
• Open source; design files available online.
• Highly modifiable for custom additions.
• Protected electronics.
• Common 4-40 hardware.
• Modular frame for fast repair.
• Protective motor mounts.
Price on the ELEV- 8 is $550.
