Advanced Triaxial Accelerometer for Race Car Performance Enhancement

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Method to Estimate the Position and Orientation of a Triaxial Accelerometer Mounted to an Industrial Manipulator

A novel method to find the orientation and position of a triaxial accelerometer mounted on a six degrees-of-freedom industrial robot is proposed and evaluated on experimental data. The method consists of two consecutive steps, where the first is to estimate the orientation of the accelerometer from static experiments. In the second step the accelerometer position relative to the robot base is i...

Comparison of uniaxial and triaxial accelerometry in the assessment of physical activity among adolescents under free-living conditions: the HELENA study

BACKGROUND Different types of devices are available and the choice about which to use depends on various factors: cost, physical characteristics, performance, and the validity and intra- and interinstrument reliability. Given the large number of studies that have used uniaxial or triaxial devices, it is of interest to know whether the different devices give similar information about PA levels a...

Method to Estimate the Position and Orientation of a Triaxial Accelerometer Mounted to an Industrial Manipulator, Report no. LiTH-ISY-R-3025

A novel method to nd the orientation and position of a triaxial accelerometer mounted on a six degrees-of-freedom industrial robot is proposed and evaluated on experimental data. The method consists of two consecutive steps, where the rst is to estimate the orientation of the sensor data from static experiments. In the second step the sensor position relative to the robot base is identi ed usin...

The validity of the non-exercise activity thermogenesis questionnaire evaluated by objectively measured daily physical activity by the triaxial accelerometer

BACKGROUND Physical inactivity is a major cardiovascular risk factor. Recently, we showed that non-exercise activity thermogenesis (NEAT) assessed by the self-reported questionnaire is favorably associated with metabolic risks in patients with type 2 diabetes. The purpose of the present study was to examine the validity of the questionnaire by comparing with objectively measured daily physical ...
