Assignee: MILWAUKEE ELECTRIC TOOL CORPORATION
Field: Machine tools (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A power tool comprising:
a housing;
an anvil supported by the housing;
a motor positioned within the housing configured to drive the anvil;
a hammer mechanically coupled to the motor, the hammer configured to deliver impacts to the anvil; and
a processor configured to:
determine a motor characteristic indicative of a parameter of the motor,
when the motor characteristic indicates that the parameter of the motor is below a threshold,
employ an acceleration-based technique to detect a first impact based on a change in motor acceleration, and
generate a first impact indication in response to detecting the first impact,

and
when the motor characteristic indicates that the parameter exceeds the threshold,
employ a time-based technique to detect a second impact based on an elapsed time, and
generate a second impact indication in response to detecting the second impact.
