2. Requests from the market:
- Increased speed
- Increased quality
- Guaranteed safety
Downside:
- Same or less budget
- More challenging conditions
TRENDS
4. The right sensor - simply not enough
- Innovative sensor technology
- Smart mechanical engineering teams
and
- In depth know how of thermal processes
APPROACH
8. Potential Market for Fat Destruction Procedures
In a survey of 1,045 women in NA
56%
indicated interest in non-invasive fat destruction procedures
Total Addressable Market in the US: 19.5M Patients
World Market: $2 billion
by 2017 ($700 million in
the US - Globaldata)
MARKET SIZE
9. Survey Takeaway:
• “Pain-free with no downtime, it’s effective and totally
believable.”
• “Over 75% of patients come in to my office and immediately
ask “How much is it going to hurt?"
PAIN FREE TREATMENT - SAFETY
12. Next generation, Velashape III:
- Pain free treatments
- More efficient treatment
- No downtime.
Request
- Non contact temperature sensor integrated in applicator for
skin temperature monitoring
- Closed loop RF mechanism to ensure reaching the set-point
skin temperature for optimal treatment efficacy, and NOT
exceed the set-point temperature for patient safety and
comfort.
OBJECTIVE SYNERON
13. Our challenges:
- Size – very limited space
available
- Direct IR lamp interference
- Field of view – lens
- Ambient temperature
fluctuations
- Gel applied on skin: thermal
gradient.
CHALLENGES
14. Solution: Sensor selection:
- Small size
- Thermocouple compatible
- Unpowered
- No drift
- High accuracy
- High repeatability
- High interchangeability.
OUR CHALLENGE: SIZE – VERY LIMITED
SPACE AVAILABLE
15. Direct influence from IR lamps:
immediate sensor response when IR
lamps were switched on –
measurement error of approx 3C.
OUR CHALLENGE: DIRECT IR LAMP
INTERFERENCE
16. Inner copper shroud blocking IR lamp radiation.
Inner surface of shroud must be very low emissivity,
otherwise the temperature of the shroud itself is
measured.
SOLUTION: DIRECT IR LAMP INTERFERENCE
20. No Power Required
T/C Compatible
Compensates for the Ambient Temperature
AMBIENT TEMPERATURE COMPENSATION
21. ZnSe lens and window are not 100% transparent for IR
radiation – some signal is absorbed:
Sensor spectral response: 5.5 – 20 µm
OUR CHALLENGE: BIG AMBIENT
TEMPERATURE FLUCTUATIONS
22. The thermopile detector is responsive to the net power that it absorbs:
P = σ * A * (Tt4 - Ta4)
The Stefan-Boltzmann equation where:
- P = net radiation power
- A = surface area
- Tt = target temperature
- Ta = detector temperature.
Since the detector absorbs power at σ * A * (Tt4) and re-radiates power
at its own temperature, the σ * A * (- Ta4) term is needed.
Tt is attenuated by the additional lens and window attenuate
Ta is unchanged: ambient compensation error
OUR CHALLENGE: BIG AMBIENT
TEMPERATURE FLUCTUATIONS
23. 1) Sensor thermally isolated: slower heat up and more
uniform heating
2) Additional thermocouple to measure sensor housing
temperature to allow accurate ambient temperature
compensation1.
1: solution that is provided to Syneron is under NDA and can not be
disclosed here. The example given here is more general in nature but covers
the concept
SOLUTION: BIG AMBIENT TEMPERATURE
FLUCTUATIONS
26. The results for Tt=24C and Tt=59C.
- IRt/c = Initial temp. in degC,
- t/c = additonal t/c temp in degC,
- Corrected: with ambient temperature compensation
- Scaled: with heat balance.
RESULTS
27. VelaShape III Advantages
Increased RF Power:
- End point temperature is achieved much faster
- Reduction in treatment time
- Consistent, reproducible resultst
Sophisticated Feedback Mechanisms:
- New closed loop RF mechanism and built in
temperature sensor
- Better monitoring for elevated temperature in
the tissue
- Increased patient comfort and safety
Movie
28. Two important items I would like you to
walk away with:
1. Market is very demanding and keeps on
challenging the industry
2. There is always a solution if the thermal
process is thoroughly understood –
sensor by design.

Editor's Notes
Sensor = non contact infrared temperature sensors
- peil audience: wie in print, wie in medisch etc?
Wat willen jullie zien/horen
Uitdagingen worden te groot – off the shelve niet meer genoeg: steeds complexere machines
Voorbeeld: HP: dubbele druk – concurrentie en druk van binnenuit. Hogere snelheid en nauwkeurigheid steeds belangrijker, en liefst zo klein mogelijk. Dit heeft grote gevolgen voor thermische processen.
Getallen van de markt – groeimarkt. Non contact IR heel belangrijk voor snelheid en safety
Goed voorbeeld: cosmetisch industry is growing – vrouwen blijven vrouwen en het wordt bijna zomer
Syneron was marktleiden, maar dreigde die positie kwijt te raken. Moest een nieuwe flagship komen om weer nr1 in de markt te worden. Luisteren naar de klant.
Apoptosis of fat tissue: heating up fat tissue to set point temperature for certain time: fat tissue destroyed
Apoptosis of fat tissue: heating up fat tissue to set point temperature for certain time: fat tissue destroyed
Patients: pain free No lawsuits!!!!
. Specialists: faster and no downtime – dus meer treatments in een dag – bigger revenue.
Bredere doelgroep: van artsen naar beauty clinics – easy to use and safety guaranteed.
ONZE challenges
Praat over ‘we found a sensor’ niet Exergen specifiek benoemen
Unique solution for Syneron is under NDA: the solutions given here are more general in nature but grasp the concept
Non-contact IR sensing: only surface temperature is measured, which in this case is the gel and not the skin.
Flagship product met enorme voordelen – USP met als belangrijkste: safety.
