Tiivistelmä
The purpose of this thesis work was to find an alternative method of watch hand calibration which would allow for optically intact watch face to be used in the product. Another goal was to improve the robustness for external interference from the existing solution used.
The thesis consists of theoretical research on collected methods and discussion on whether these could be implemented to the system. From these, two alternatives have been selected which have been described in more detail. For these, conceptual proof-of-concept measurements have also been conducted, using the laboratory equipment provided by the company.
Resulting from this thesis work, two possible replacements have been tested out of which one has been selected for further development. Work is being carried out on how to implement the sensing solution for the existing product with minimal modifications on the products current design. From one of the sensors an evaluation board has been designed and will be used in the development of the calibration sensor.
As a result of the project a unique sensing solution was found which will be tried out on future designs.
