Abstract: A system is provided for use in an industrial loading dock wherein the location of an industrial vehicle is detected and tracked in real-time, and one or more safety zones are created such that a computer or microcontroller triggers a response in the industrial vehicle upon the vehicle's entry into each such zone. The system includes a plurality of anchor radio transceivers positioned in proximity to a workspace. Each anchor radio transceiver is positioned in a known location such that the plurality of anchor radio transceivers form a fixed array of anchor radio transceivers. At least one mobile radio transceiver associated with a mobile industrial vehicle is also provided. The mobile radio transceiver is configured to exchange data packets of information with one or more of the plurality of anchor radio transceivers. A computer is provided that is in communication with the fixed array of radio transceivers.

Abstract: A system and method for detecting a position of a person or second machine relative to a machine is provided. The system includes a transmitter system located on the machine, a locator for being carried by the person, means for determining the position of said locator relative to the transmitter system, means for defining one or more safety zones around the machine; and warning means for generating a signal when said locator enters into any of said one or more safety zones. The transmitter system includes a controller for generating a uniquely encoded magnetic signal and a plurality of drivers in communication with the controller for transmitting the uniquely encoded magnetic signal. According to the method a uniquely encoded magnetic signal is generated and transmitted around the machine from a transmitter system located on the machine. The magnetic signal is received and processed at a locator carried by the person.
