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.

A power pack for a power tool. The power pack includes an electric motor configured to drive a power tool. The power pack also includes a motor controller with a relay circuit communicating with the electric motor. The relay circuit has a switch that may be connected to a power supply, whereby the power supply powers the electric motor. The power pack also comprises non-transitory computer-readable storage media having computer-executable instructions for monitoring operation of the 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 at least in part 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.

Systems and methods for restricting motor operation for wireless handheld knives

A system for controlling operation of a power tool. The system includes a handpiece having a power tool, a radio frequency identification (RFID) tag, and a wireless transceiver. The system also includes a power pack having an electric motor driving the power tool. The power pack also includes a wireless transceiver, an RFID reader, and non-transitory computer-readable storage media having computer-executable instructions for pairing the handpiece to the power pack. When executed by at least one processor, the computer-executable instructions cause the at least one processor to: interrogate the RFID tag with the RFID reader; receive an RFID signal from the RFID tag including identifying information for the handpiece; store the unique identifying information for the handpiece at the power pack; and, based on receipt of the unique identifying information, complete wireless pairing of the handpiece to the power pack.

In one aspect, a wake-up circuit is provided for triggering a determination of an absolute rotational position of a rotatable shaft of a motor in an electric power steering system of a vehicle. The wake-up circuit includes a plurality of inputs coupled to separate phases of the motor. A voltage boosting circuit is operable to increase a back electromotive force (EMF) voltage induced on one or more of the inputs by rotation of the rotatable shaft of the motor and produce at least one voltage-boosted back EMF voltage. A comparator circuit is operable to compare the at least one voltage-boosted back EMF voltage to a reference voltage and trigger a monitoring system to perform the determination of the absolute rotational position of the rotatable shaft of the motor in the electric power steering system based on a result of the compare during an ignition off state of the vehicle.
