Accelerometer Measured Physical Activity and Obesity
The use of accelerometers to objectively measure physical activity (PA) volume does not account for inter-individual differences in body mass or cardiorespiratory fitness among adults, which may contribute to the commonly observed discrepancies between objective and subjective measures of PA. Using …

Development of a light force accelerometer
In this work, the feasibility of a light force accelerometer was experimentally demonstrated. The light force accelerometer is an optical inertial sensor which uses focused laser light to levitate and trap glass microspheres as proof masses. Acceleration is measured by force rebalancing, which is …

Planetary navigation activity recognition using wearable accelerometer data
… Early results indicate that a single three-axis accelerometer is sufficient to identify the occurrence of a given PNFT activity. A custom, embedded acceleration monitoring system employing ZigBee transmission is under development for future real-time activity recognition studies. A different GUI …

Toward a demonstration of a Light Force Accelerometer
The Light Force Accelerometer (LFA) is an optical inertial sensor in which radiation pressure from two counter-propagating laser beams optically confines a glass microsphere. Inertial acceleration of the device results in microsphere displacement along the sensitive axis, which is subsequently …

Quantification of eccentric load using accelerometer imbedded in GPS
Global positioning system (GPS) with a triaxial accelerometer is widely used to monitor movements of athletes in games and training, and “body load” (BL) representing the accumulation of the rate of changes in three planes of movements is obtained to determine the training load of a session. …
