Electronic Caliper Configured to Generate Power for Measurement Operations

An electrically powered caliper configured to generate power for measurement operations, the caliper comprising:

• a scale member;
• a slider;
• a signal processing portion configured to measure a displacement between the scale member and the slider;
• and
• a power generating arrangement fixed relative 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,
• wherein:
• the power generating arrangement generates power as the user opens or closes the caliper;
• and
• the power generating arrangement 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.
