Framingham Heart Study

Gait Measurement Timer

This device is used by the Framingham Heart Study to measure the walking gait of study subjects over a fixed course. Two infrared light beams provide a precise measurement of the time interval required for the subject to cover the course. The time of day is displayed along with two successive time measurements.

The device was build on a custom PC board using an Atmel microcontroller with a back-lit LCD display. The unit may operate on batteries for portable use, or wall power for fixed use.
