Abstract
A glove with electrical contacts and a power tool with electrical contacts are electrically coupled together. Before they are coupled, the glove contacts have a high impedance with the power source. Upon coupling, circuitry within the power tool is powered by the electrical current emanating from the glove contacts, and a coded signal is generated. This coded signal is received and causes the gloved contacts to exhibit comparatively lower impedance and conduct a higher current while the coded signal is maintained. During this time, currents at the power supply and powered tool are measured and compared. While these currents remain within prescribed tolerance, the business end of the power-tool is operational or operated.
