Abstract: A rotary motor driven tool comprising a motor, and a driven part, the motor being adapted to rotate the driven part, and a torque limiting device adapted to limit torque output of the driven part to a maximum output torque magnitude, wherein the tool further includes a switching apparatus which operates automatically to initiate switching of the maximum output torque set by the torque limiting device from a first lower magnitude to a second higher magnitude when a predetermined threshold is reached.

Abstract: A device for transmitting data between a transmitter provided with standard software adapted to a serial interface and a standard receiver provided with a serial interface is presented. The device includes a serial interface simulator which replaces the serial interface of the transmitter, a memory which stores data received by the serial interface simulator, and an interface which transmits to the receiver the data stored in the memory. The serial interface simulator includes a data transmission register, a data reception register, a first buffer register, a second buffer register, a bus, a simulation control register and a simulation state register.The standard software places data in the data transmission register and receives data from the data reception register. Data placed in the data transmission register is not immediately serially transmitted to the receiver, but is transferred to the first buffer register from where it is transferred to the memory.
