Abstract
An electronic caliper generates power for measurement operations. The caliper comprises a scale member, a slider, a signal processing portion configured to measure a displacement between the scale member and slider, a power generating arrangement attached to the slider comprising a gear assembly configured to rotate in response to a force provided through the scale member to the gear assembly by a user opening or closing the caliper, and a power generator coupled to the gear assembly and configured to rotate in response to force provided by the rotating gear assembly and provide power to the signal processing portion. The power generating arrangement generates power as the user opens or closes the caliper and is configured such that it contributes a motion resistance force component of at most 20N during the user opening or closing the caliper using a maximum manual acceleration and/or speed.
