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.

Systems and methods for monitoring a wireless motor drive control system for handheld knives

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.

A method of reducing contamination in a silicon product includes: moving silicon pieces along a conveyance system, wherein the conveyance system comprises a liner having a polished surface finish with a surface roughness of less than or equal to 12 microinches; and moving the silicon pieces across the conveyance system, wherein the silicon pieces contain a reduced number of impurities as compared to silicon pieces in contact with a liner having an unpolished surface. A crushing tool includes: crushing tool elements configured to crush silicon into fragments, wherein the crushing tool elements comprise a surface comprising a polished surface finish with a surface roughness of less than or equal to 12 microinches. A conveyance system includes: a first conveyor discharged onto a second conveyor; wherein the first conveyor comprises a first liner and wherein the second conveyor comprises a second liner.
