US Patent 9061392 Controlled electro-pneumatic power tools and interactive consumable

A controlled electro-pneumatic power tool includes an electro-mechanical adjustable valve, a pneumatic motor and a rotational speed sensor connected to a microcontroller for the selection, monitoring and adjustment adjustment of the rotational speed in real time. Using the communication port data for the consumable can be transmitted to the controlled electro-pneumatic power tool. The controlled electro-pneumatic power tool can read and utilize the transmitted data to select, adjust and maintain the optimum process parameters for the consumable without any input from the operator person. Furthermore, the communicated data can be used to warn the operator person that the tool used is inadequate for the selected consumable.
