128:(SLAMMD) was installed in the HRF-1 during Expedition 11. The SLAMMD measures the on-orbit mass of the crewmembers by applying Newton's second law of motion (force is equal to mass times acceleration). This device can measure a mass between 95 and 240 lb using the force generated by two springs inside the SLAMMD drawer. Each spring is attached to a cam, which is also attached to a centrally located shaft with a flywheel mounted on top of it. The cam is designed such that, as the springs are stretched over a distance, a constant force is applied to the central shaft. A lanyard wrapped around the large flywheel is fed through a small slit on the SLAMMD front panel. The lanyard is latched onto the SLAMMD guiding arm, where the crewmember sits for a body mass measurement. Attached to the guiding arm is a leg support assembly around which the crew-member wraps his or her legs (as one would for a leg curl machine), a belly pad to help align the stomach, and a headrest.
