Designed a portable tracker with controls and displays on the Web rather than on the body to make a very light wearable component?only 0.8 ounces.
Created an accurate pedometer mechanism that would measure the number of steps a person takes during a day by taking a diverse cross section of the general population and characterizing the impact force of their walking or running.
Packaged the entire mechanism and electronics for the pedometer, custom contacts, and RF receiver in a device small enough to be worn on a person's waist without being conspicuous.
