One of the key problems in accelerometry based gait analyses is that it may not be possible to attach an accelerometer to the lower trunk so that its axes are perfectly aligned to the axes of the subject. In this paper we will present an algorithm that was designed to virtually align the axes of the accelerometer to the axes of the subject during walking(More)
A method to align the coordinate system of accelerometers to the axes of a human body: the depitch algorithm Abstract One of the key problems in accelerometry based gait analyses is that it may not be possible to attach an accelerometer to the lower trunk so that its axes are perfectly aligned to the axes of the subject. In this paper we will present an(More)
The accuracy of AD converters can be improved by error correction. The presented ADC analyzer and calibrator, based on a histogram test with small triangular input signals, determines the static errors like gain, offset and linearity. The advantages of the principle are fast results with a high level of confidence and small experimental burden.
