Market

• We Offer Licensees A Variety of Cutting Edge Patented

Temperature Sensing and Control Technologies

– We Will Discuss Three of Those Today – In Order of Product Maturity

CONFIDENTIAL

Surface Buffet -

CookTek

1 2

Aerospace Composite

Curing/Repair – AvPro

Rubber Processing

Monitor/Control – Dynisco

CONFIDENTIAL

Microwire Temperature Sensing Systems

• Components - Similar to RFID

– Reader – Transmit Power/Receive/Data Analysis

• Located Outside of Curing/Hot Environment

– Antennae – Copper Coils/Substrate

• Inside Curing/Hot Environment (Up to Four Per Today’s Reader)

– Magnetic Temperature Sensor (MTS) • Molded Permanently into Object (One Per Antenna)

– Host Computer

• Computer Software Can be Moved to Reader Micro

CONFIDENTIAL


• Why Should You Care? Why Not RFID? – MTS’s Can Be Read Remotely Through Conducting Material

• We Can Read MTS Temperature Through Carbon Fibers, Tire Steel Belts, etc.

– MTS’s Are So Small That They Do Not Constitute a Part Flaw

• 0.09” Diameter Tube, One Inch Long

– MTS’s Survive High Temperatures/Pressures

• Can Survive Tire Molding Process, Composite Curing Process, etc.

CONFIDENTIAL


• Features

– Self-Calibrating Sensor -- During The Process

• This is a Process Sensor – We Assume That The Sensor is

Embedded In a Place Where Actual Temperature Is NOT

Measured By Any Other Sensor – Thus No Way To Know

Starting Temperature

– Non-Linear Temperature Accuracy

• More Accurate Near Curie Temperature (216.5C/422F) Than Far Below

It ( 175C – 216.5C, +/- 2C, 150C - 175C, +/- 3C, 61C-150C, +/-4C)

– Polling Rate

• Approximately One Per Second

CONFIDENTIAL


• Theory Basics

– We are Measuring Normalized Saturization

Magnetization of Sensing Microwire

• Known Dependence Upon Temperature

• Calibration of Normalized Ms vs. T Curve at Two Points (Upper – Curie

Temp of Sensing Wire; Lower – Curie Point of Third Autocalibration

Wire DURING PROCESS)

CONFIDENTIAL


• Theory Basics

LOWER TEMPERATURE HIGHER TEMPERATURE

CONFIDENTIAL


• Representative Results for Autoclave Curing

Autocalibration Point

CONFIDENTIAL

Example Microwire Sensing Process: Tire Curing

• Microwire Sensor (MTS) Embedded in Tire Tread During Layup of Uncured Tire – Antenna Moves Into Position After Mold Closes to Allow Remote

Measurement of MTS Temperature. Information Is Used to Stop Press When Tire Has Actually Achieved Cure State – Not Simply After a Generic Time/Temperature Profile That Capture ALL “Cakes”

CONFIDENTIAL

Eddy Current Thermometer

• Components - Similar to RFID

– Reader – Transmit Power/Receive/Data Analysis

• Remote From Object To Be Measured

– Antennae – Copper Coils/Substrate

• Remote From Object To Be Measured

– Sensor – Highly Conductive Object (Coin, Stick, etc.)

Placed Next to Object to Be Measured OR

Object Itself (if Has a Conductive Layer)

– Host Computer

• Computer Software Can be Moved to Reader Micro

CONFIDENTIAL

Eddy Current Thermometer • Why Should You Care? Why Not RFID?

– Sensor Can Be Remotely Read Through Multiple Thick

Layers of Stainless Steel or Non-Magnetic Metals

• For Instance, A Clad Cooking Pan (SS/Aluminum/SS) Can Be the

Sensor

– Sensors are Inexpensive

• Aluminum, Copper, or Like-Alloy Coins, Sticks, etc. – Can Be

Plated With Stainless Steel for Non-Corrosion – OR Object Itself

– Sensors Can Withstand High Temperature

• Upper Limit is Melting Temperature of Metal Used, Extremely

Low Temperature Limit

CONFIDENTIAL

Eddy Current Thermometer • Features

– One-Time Calibration -- Upon Installation • Single Temperature Calibration

– Measured Temperature Independent of

Antenna-To-Sensor Distance

– High Temperature Accuracy • Linear Accuracy +/- 1C

– Polling Rate • Approximately One Per Second

CONFIDENTIAL

Eddy Current Thermometer

• Theory Basics

– We are Measuring Voltage Induced in Our

Antenna Receive Coil Caused by Induced Eddy

Currents in the Sensor • Known Dependence Upon Bulk Conductivity of Metal

• Conductivity of KNOWN Metal (Sensor) Has Well-Documented

Dependence Upon Temperature – Thus We Deduce Temperature

CONFIDENTIAL

Example Eddy Current Thermometer Application

• Stainless-Clad Copper Coin Welded to Position Inside Stainless Pressure Vessel

– Antenna Can Be Placed Adjacent Outer Vessel Wall to Read Temperature Inside of Pressure

Vessel

– NO FITTING REQUIRED FOR THERMOCOUPLE THAT IS A LEAK WAITING TO HAPPEN

Antenna Can

Be Part of

Hand Held,

Battery

Powered

Industrial Wireless Solution Design

Considerations

When moving parts are an issue

(Wire and connector integrity)

Key Wireless Applications



Key Wireless Applications, cont’d

When long cable lengths are needed

(Cost)



Key Wireless Applications, cont’d

When project schedules are tight, when

field time is needed or when retrofitting

existing installations



Why the Growth in Industrial? Reduced wiring complexity

Cuts commissioning time

Eliminates wire and connector integrity issues

Solves electrical isolation challenges

Fewer tripping hazards

No trenching or breaking concrete

Simplified trouble-shooting

Not tethered by the wire - flexibility (add/move/change)

Lower cost on long wire runs

Can be applied where traditional devices are not feasible



Things to Consider • Look for solutions that provide device diagnostics

• Consider mounting locations for best signal strength

• Look for self healing network (retries)

• Look for standards-based encryption

• If considering WiFi, discuss with IT first (who controls?)

• Understand difference between Security and Interference

• Easy to commission with set-up tools and diagnostics

• Not all wireless is the same – try them first

• Automatic field pairing and diagnostic information

• Ensure RF used is globally license-free

• Configurable to interface with standard controllers

• Low power

• Consider trade-offs between a packaged device, and interfaces that require additional packaging

• Consider EMI/EMC requirements. Require test data.

• Look at sealing and temp ratings of the field devices

• Mesh network verses Point-2-Point

• Differentiator for wireless many times is the end user
