WelcomeWelcome
s computers become a part of daily life, a technology that makes
themeasiertousehasbecomeanecessity. Carroll Touch provides
the solution through the power of touch.
Because pointing or touching is a natural means of indicating choice,
touch systems are ideal for selection-based applications where
easy-to-follow menus guide a user through a series of steps or choices.
Touch is well accepted by the casual user because its simple, natural
interface hides the complexity of computer systems.
The modular flat panel touch system is especially well-suited to rugged
environments, such as industrial settings where exposure to chemicals
is likely, medical settings where the system must be scrubbed after
every use, and public settings (such as kiosks) that subject the system
to repeated, possibly abusive use.
Thank you for your interest in Carroll Touch products!
Purpose
This guide explains the operation of a scanning infrared (IR) touch
system and reviews the types of mounting, sealing and coating
techniques to adapt an IR touch system to various environmental and
chemical factors.

Audience
This guide is intended for analysts who need to determine how to use
and/or adapt an infrared scanning touch system to the needs of their
particular application.
Organization
Chapter 1, “Introduction,” contains a brief technological overview of
the ways in which scanning infrared touch systems function. The
chapter goes on to list environmental factors affecting touch, such as
temperature, ambient light, chemicals, particulate contaminants,
moisture, shock and vibration.
Chapter 2, “Flat Panel Mounting Techniques,” illustrates four separate
mounting schemes, each of which is designed to increase the
functionality of the touch system in reaction to a different environment.
The mounting methods include simple, typical NEMA/4,
anti-shock/vibration, and industrial/medical.
Chapter3, “Bezel/Filter Assembly,” shows themodular flat panel bezel
and filter and its standard manufacturing material, along with its
chemical properties.
Chapter 4, “Sealing and Coating,” discusses the concept of sealing,
along with an explanation of how to seal the modular flat panel touch
system. The concept of coating and reasons for it are explained, along
with Carroll Touch conformal coating.
The Glossary defines terms that are unique or whose usage is unique to
touch.
Conventions
For clarity, this guide uses certain conventions to visually distinguish
different types of information. The conventions are:
•Bold is used to emphasize a word or phrase, including definitions
of important concepts.
•Information of particular importance or actions that may have
undesirable results if performed improperly are included under the
headings Note and Caution.

Technological Overview
The operation of all scanning infrared (IR) touch systems is based on
the creation of a grid of IR light beams above the viewing surface of a
CRT monitor or flat panel display and the recognition of the location at
which individual beams within the grid are interrupted. To create such
a grid, IR light emittingdiodes (LEDs) arepaired with phototransistors,
each set constituting an opto-pair or physical beam, to create a
horizontal (x-axis) and a vertical (y-axis) array of beams. The two
arrays of beams and their circuitry make up an opto-matrix frame, as
shown in Figure 1-1.
Figure 1-1. Scanning Infrared Technology
As shown in Figure 1-2, a Carroll Touch modular touch frame designed
to function with a flat panel is composed of an opto-matrix frame, an
IR-transparent protective bezel, and a transparent filter. To complete
the touch system, the modular touch frame is linked to a modular touch
controller via the modular digital interface (MDI), which is a standard
8-pin telephone-type plug attached to the touch frame by an 8-pin cable.

Environmental Factors
Traditionally, the successful implementation of a scanning IR touch
system has required that certain factors in the operational environment
be addressed. Historically, the environmental factors that could
influence the operation of a touch system were temperature, shock and
vibration, chemicals, moisture, ambient light, and particulate
contaminants (dust, dirt, etc.). Today’s Carroll Touch modular touch
systems with their improved hardware, software and firmware,
compensatefor theseenvironmentalconditions, alongwithsuch factors
asmisalignment ordegradation oftheopto-electronic devices,reducing
their ability to affect touch system operations.
Temperature
Carroll Touch’s use of solid state electronics and its ASIC-based
modular circuitry enables the touch system to withstand and adapt to
temperature extremes as well or better than the host display and system.
The standard Carroll Touch modular flat panel system is designed to
function in the temperature range from 0° C to 50° C (32° F to 122° F)
and can be stored in the range from -20° C to 75° C (-4° F to 167° F).
Customer systems have been designed to function at temperatures from
-55° C to 125° C (-67° F to 257° F). For heat dissipation, Carroll Touch
modular touch systems are designed to operate at altitudes up to 10,000
feet (3,048 meters) and at 0% to 95% non-condensing humidity, over
the full temperature range.
