    摘要： An apparatus and method for obtaining data stored in an electronic module within a power tool over a power line cord of the tool, and without any disassembly of the tool being required. An interface subsystem applies a high frequency, low power AC input signal to the power cord of the tool. A controller within the tool recognizes this signal as an indication that the tool is to be placed in a communications mode. The controller modulates a power switching device used for turning on and off the motor of the tool in such a fashion that current pulses are transmitted over the power line cord back to the interface subsystem. The current pulses correspond to tool usage/performance/identification information stored in the electronic module of the tool. This information is interpreted by a current reader circuit of the interface subsystem as binary information which is then transmitted to an external computing device for analysis and/or recording.

    摘要： A method for preventing sudden inadvertent operation of a motor of a tool or appliance when the motor is initially electrically connected to a power source while an On/Off switch for controlling the motor is in a closed (i.e. ‘On’) position. The method includes electrically connecting the motor to a power source and determining a position of the On/Off switch when the motor is initially electrically connected to the power source. The position of the On/Off switch is determined by either sensing whether current is flowing through the motor or voltage is present at the motor when the motor is initially connected to the power source.
