Consistent market growth, strong global trends driving future

Aging populations• By 2020 double the people will be over 60 years old

as in 2000

Sources: World Health Report, Databeans, Frost & Sullivan, Economic Times

Remote and emerging markets• China healthcare expenditure increased from 3.7% of

GDP in 1995 to 5.6% in 2007• India government proposed in 2008 to increase public

expenditure on health care from 1% to 3% of GDP

Personal healthcare• 33% of medical semiconductor revenue in 2008

went into consumer medical devices

Rising healthcare costs• U.S. healthcare spending more than 15% of GDP, Europe not far behind• Costs expected to grow from $2 trillion in 2007 to $3.1 trillion in 2012

Pulse Oximeter

• Measures the oxygen level in the arterial blood

• Measures the heart rate

What is it used for?

• To indicate the percentage of oxygen saturation in the blood• Normal arterial blood is technically 100% saturated for a healthy

individual.

Page 32: 8463.TI Medical Solutions With MSP430 1Q12

TI Confidential – NDA Restrictions

How A Pulse Oximeter Works

• Red and infrared light is shone through the body, typically a finger

• Absorption of different body tissues except the arteries is static DC

• Arteries provide a dynamic light absorption or AC

• The amplitude of the arterial absorption is measured for both red and infrared light sources

• Ratio between the two emerged light amplitudes indicates the HbO2 level

A Customer Testimonial by BodyMedia

“It’s a fascinating little device that may have a huge impact on behavior modification. The armband has tremendous potential to educate the masses about their true activity level, which is often exaggerated, and motivate them to get up and get moving like they should be.”

Dr. Tedd Mitchell, President and Chief Operating Officer of the Cooper Clinic at the Cooper Aerobics Center, Dallas TX.

“TI continues to lead the industry as our gold standard in low power micro-controllers. Their highly integrated components, low cost development tools, and easy ramp-up to productivity cut our design time and provided our customers with a superior product.”

Scott BoehmkeDirector of Hardware Development, BodyMedia, Inc
