An electronic knife assembly and associated systems and methods are disclosed herein. In some embodiments, the knife includes a blade and a handle operably couplable to the blade. The handle can include an oscillator operably coupled to the blade, at least one sensor configured to obtain one or more measurements, and a controller operably coupled to the oscillator and the least one sensor. The measurements from the sensor can include a spatial position of the electronic knife, a spatial orientation of the electronic knife, a mass of a user's hand, a grip of the user's hand, and/or a resistance to the oscillation of the blade. The controller can adjust an operating frequency of the oscillator based at least partially on the one or more measurements from the at least one sensor. The handle can also include a wireless power supply.

A power pack for a power tool. The power pack includes an electric motor configured for driving engagement with the power tool. The power pack also includes a motor controller having a relay circuit connected a electric motor. The relay circuit includes has a switch selectively connected to a power supply. The power supply powers the electric motor. The motor controller also includes non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the stored power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: monitor input data relating to operation of the power pack; determine, based on the input data, that operation of the power pack deviated from an ideal state; and, based on the determination of deviation, cause the switch to electrically disconnect the electric motor from the power supply.

The present invention relates to the technical field of cutting devices, and in particular, to an oscillating saw connector and a blade connected thereto, including a connector body. The connector body provided by the present invention is configured to connect an oscillating saw at one end and a blade at the other end, and kinetic energy transmitted from the oscillating saw drives the blade to move for cutting materials, featuring operational convenience and enhanced cutting force, as well as stable blade motion and improved dimensional accuracy during cutting; the connector body can accommodate different types of blades, and compared to conventional direct connection between an oscillating saw and a blade, no additional mounting holes are required to be formed in the blade for connection with the oscillating saw, thereby reducing the overall blade length to lower manufacturing costs, and decreasing replacement costs when the blade is damaged.
