  • Patent number: 12213753
    Abstract: A method for providing a visual indication regarding a state of an instrument comprises sensing usage information about the instrument and using a motor to rotate an indicator body from a first position to a second position in response to sensing the usage information meets a predetermined condition. The method further comprises holding the indicator body in the first position or the second position, respectively. In the first position a first portion of the indicator body is visible on an exterior of the instrument and in the second position a second portion is visible. In the first position, the first portion of the indicator body provides a visual indication that the usage information of the instrument does not meet the predetermined condition, and in the second position the second portion of the visual indicator body provides a visual indication that the usage information of the instrument meets the predetermined condition.
