ROTATION SENSOR FOR A CROWN OF AN ELECTRONIC WATCH - A simplified explanation of the abstract

This abstract first appeared for US patent application 17840222 titled 'ROTATION SENSOR FOR A CROWN OF AN ELECTRONIC WATCH

Simplified Explanation

The abstract describes an electronic watch that includes a housing and a crown with a knob. The crown is designed to receive rotational input and is connected to a rotor that can rotate in response to the input. The rotor has a recess with a coating that reflects light. The watch also has an optical sensing system that can detect the rotational input by analyzing the reflected light.

  • The electronic watch has a housing and a crown with a knob.
  • The crown is connected to a rotor that can rotate.
  • The rotor has a recess with a coating that reflects light.
  • An optical sensing system is used to detect the rotational input by analyzing the reflected light.

Potential Applications

  • This technology can be used in various electronic watches to provide a more precise and reliable way of detecting rotational input.
  • It can be applied in smartwatches, fitness trackers, and other wearable devices that require rotational input for navigation or control.

Problems Solved

  • Traditional methods of detecting rotational input in electronic watches may be less accurate or prone to wear and tear.
  • This technology solves the problem of accurately detecting rotational input by utilizing an optical sensing system and a reflective coating.

Benefits

  • The use of an optical sensing system provides a more accurate and reliable way of detecting rotational input.
  • The reflective coating enhances the efficiency of the optical sensing system by reflecting a portion of the incident light.
  • This technology improves the overall functionality and user experience of electronic watches by providing a more precise and durable method of detecting rotational input.


Original Abstract Submitted

An electronic watch may include a housing and a crown configured to receive a rotational input. The crown may include a knob external to the housing, a rotor coupled to the knob and configured to rotate in response to the rotational input, the rotor defining a recess extending about a circumference of the rotor, and a coating positioned in the recess and configured to reflect at least a portion of light incident on the coating. The electronic watch may further include an optical sensing system configured to detect the rotational input using the reflected portion of the light.
