Abstract
A system for prevention of accidents by a hazardous machine. The system is comprised of a first subsystem on the machine, and a second subsystem wearable by a party to be protected. The first subsystem includes a base unit transceiver, and a processor in communication with the base unit transceiver, and in communication with a controller of the energy conversion device. The second subsystem includes a protected party remote transceiver in communication with the base unit transceiver. The processor executes an algorithm including detecting the location of the protected party remote transceiver relative to the base unit transceiver; determining if the location of the protected party remote transceiver relative to the base unit transceiver is less than a predetermined threshold distance; and halting operation of the energy conversion device of the protected party remote transceiver relative to the base unit transceiver is located at less than the threshold distance.
