2015/10/64 Motivation 2015/10/64  36% of all death in U.S. are caused by cardiovascular diseases in 2007 American Heart Association  Physicians cannot effectively predict heart attac Study conducted by Dr. Lewis Kuller  “Heart rate itself does not completely reflect the state of the health of the heart, without knowing what the person is doing.” Dr. William New, Stanford University Copyright © 2008 Corazon Engineering Inc.

2015/10/65 Existing Heart Rate Monitoring System 2015/10/65  Most devices monitors heart rate only  Do not know the activity associated with heart rate  Lack of mobility for medical equipments Copyright © 2008 Corazon Engineering Inc.

2015/10/66 Our Solution  Heart rate with their associated activity  Non-invasive and mobile  Monitoring result is transferable to medical professionals  Affordable Copyright © 2008 Corazon Engineering Inc.

2015/10/67 7 Corazon Engineering Inc.  Why we name ourselves Corazon? -Corazon means “Heart” in Spanish.  Our Mission Statement - Applying the cutting-edge technology to develop innovative products on preventing heart related disease. Copyright © 2008 Corazon Engineering Inc.
