Abstract:
1. A proximity detection system comprising: a first magnetic field generator for generating a first oscillating magnetic field, the first magnetic field generator being arranged on a first vehicle, wherein at least one of the size and strength of the first oscillating magnetic field is adjustable; a second magnetic field generator for generating a second oscillating magnetic field, the second magnetic field generator being arranged on a second vehicle, wherein at least one of the size and strength of the second oscillating magnetic field is adjustable; a first magnetic field detector capable of detecting the second oscillating magnetic field and generating a signal for providing a visual and/or audible warning to an operator of the first vehicle upon detecting the second oscillating magnetic field; and a second magnetic field detector capable of detecting the first oscillating magnetic field and generating a signal for providing a visual and/or audible warning to an operator of the second vehicle upon detecting the first oscillating magnetic field.
