Abstract: An apparatus (100) may include a working assembly (220) configured to perform a work function responsive to operation of the working assembly, an electric motor (230) that powers the working assembly, a power source (210) configured to selectively power the electric motor, a control circuitry (240) for controlling operation of the electric motor, and a brake function (270) configured to selectively apply braking to the electric motor responsive to a brake initiation event. The brake function may be configured to apply the braking by short-circuiting motor phase windings of the electric motor without requiring an external power supply during application of the braking.

Abstract: A battery pack (150) may include one or more rechargeable battery cells (350) and processing circuitry (310). The processing circuitry (310) may be configured to control extraction of operational parameters from a device (200) to which the battery pack (150) is operably coupled and wireless communication of the operational parameters from the battery pack (150) to an access point (160). The operational parameters may include at least one parameter that is not determined based on measuring battery parameters. The device (200) is one of a plurality of different devices with which the battery pack (150) is configured to be operably coupled.

Abstract: A method of controlling operation of a hand held power tool may include receiving information indicative of a type of cutting equipment attached to the hand held power tool (100) based on operation of a working assembly (130) in a selected direction of rotation. The working assembly (130) may be configured to be bi-directionally rotatable to perform a cutting function using cutting equipment attachable to the hand held power tool (100). The method may further include determining the type of cutting equipment attached based on the received information, and selectively inserting an operational constraint on the working assembly based on the type of cutting equipment and a selected direction of rotation for the working assembly.
