Trident Systems Adds 3M MicroTouch DST Technology to Expand Extensive Touch Offering

METHUEN, Mass.--(Business Wire)--
3M Touch Systems, Inc., a wholly-owned subsidiary of 3M and a
leading innovator and manufacturer of touch technology, today
announces that long-time touch solutions provider, Trident Systems
Inc., will offer interactive signage displays integrated with 3M
MicroTouch(TM) DST touch technology in screen sizes ranging from 32"
to 46".

"Trident Systems has been offering touch solutions for nearly 20
years, so we are very pleased that a company with their extensive
touch experience has chosen the MicroTouch DST feature set to meet
their customers' interactive signage display needs," said Chris
Tsourides, business unit manager, 3M Touch Systems.

Based on 3M's patented Dispersive Signal Technology (DST),
MicroTouch DST touch systems offer display integrators an ideal
solution for large-screen interactive applications that require fast,
accurate, reliable touch response. Other unique features include
operation unaffected by surface contaminants and "dynamic touch,"
which ignores static objects on the screen and allows for multi-user
touch capabilities.

"After almost two decades of providing touch solutions to a wide
array of markets, we see DST as a truly unique touch interface that
will provide our customers with the robust touch display they need for
their large-screen interactive signage applications," said Gary
Mundrake, VP Integrated Systems Production Division, Trident Systems.

Dispersive Signal Technology recognizes touch by interpreting
bending waves within the glass substrate created by the contact of a
finger or stylus on the glass. Since bending waves are unaffected by
on-screen contaminants and surface scratches, DST touch screens are
well suited for applications, such as interactive digital signage,
public way finders, point-of-information stations, corporate
directories, retail product selectors, as well as conference room and
education presentation systems.

3M Touch Systems provides fast, reliable and accurate touch
products to customers worldwide under the "MicroTouch" brand. Popular
interactive applications include casino gaming, retail point of sale,
foodservice, hospitality, self-service, mobile handheld, and
interactive digital signage. For more information about MicroTouch
