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

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 serverTechnical Requirements: 2.4 GHz wireless systems, sensors and GPS location tracking transmitting to a
server with online accessible databasePerformance 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 caseCost Requirements: The cost of development for the implementable system design is less than
$44,000Trade Off Requirements: System lifetime is 5 yearsTest 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
