1. Problem Situation  Heart disease, cancer, and diabetes are chronic diseases affecting 90 million Americans’ quality of life  Almost 80% of Americans have one chronic disease, while over 50% are affected by more than two  System to be developed should be portable, cost no more than $200 per unit and put into operation in 6 months (Source: CDC, National Center for Health Statistics)

2. Customer Requirements  Easy to use  Low maintenance  Low cost  Provide continuous care anytime, 24 hours a day  Wide range coverage  Reliable  Emergency contact Design Statement  Provide timely access to a patient's health status to improve the patient's quality of life and reduce healthcare cost

3. Derived Requirements I/O Requirements:  Collects health-specific metrics from devices and sends to them to server Technical Requirements:  2.4 GHz wireless systems, sensors and GPS location tracking transmitting to a server with online accessible database Performance Requirements :  If the vitals or tracking information is out of the safe range or emergency button is pressed specified signal to be sent to server through a 240 kb/s network  Packages of data should be sent to server every 1 hour while there is no emergency case Cost Requirements:  The cost of development for the implementable system design is less than $44,000 Trade Off Requirements:  System lifetime is 5 years Test Requirements:  Collect data from sensors every 10 sec with the accuracy ±0.05%

5. Concept Exploration  Alternative System Design: 1. Place elderly person in nursing home 2. Hire stay at home nurse 3. Connect patient up to conventional vitals monitoring devices  Evaluation Criteria: 1. Leads to lack of independence, causes depression 2. Extremely costly and similar problems to (1) 3. Limits mobility and uncomfortable  Do Nothing Alternative:  Increase chances of injury and slower response time to emergencies
