Abstract: The present peening calibration unit comprises a casing, a transducer, and a transmission unit. The casing defines a top and a bottom. The transducer is positioned along at least a section of the top of the casing. The transducer generates an electric signal upon application of peening energy thereto. The transmission unit receives the electric signal generated by the transducer and transmits a digital signal representative of the received electrical signal wirelessly. The transmission unit is located inside the casing. Furthermore, a peening calibration battery pack and a peening calibration system are described.

Abstract: 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.

Abstract: 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 adjustement of the rotational speed in real time. The electro-pneumatic power tool may include input buttons, data ports to save data and a communication port to read/write data from an interactive consumable. The electo-pneumatic power tool may also include a battery and a generator as well as a variable speed transmission with flexible shaft and lightweight handpiece. Using the communication port, important data for the consumable, such as optimum rotation speed, optimum applied pressure and average usage time, can be transmitted to the controlled electro-pneumatic power tool. The controlled electro-pneumatic power tool can read and utilise the transmitted data to select, adjust and maintain the optimum process parameters for the consumable without any input from the operator person.

Abstract: A method of peening a surface which comprises the steps of providing a rotary peening tool having at least one rotating flap mounted on the drive shaft which is rotatably driven, measuring the speed of the drive shaft, and controlling the speed of the drive shaft to maintain a desired level. A peening apparatus is also disclosed.

Abstract: The rotational speed of a pneumatic hand tool is adjusted in real time to maintain a selected speed level irrespective of exterior parameters affecting the performance of the tool. The apparatus is comprised of a rotational speed sensor installed directly on the tool, a digital microprocessor using control algorithms, and a valve to adjust the flow of air to the tool.
