Abstract
The invention relates to a complex proximity safety and warning system. The invention provides a safety system comprising a generator that generates a magnetic field that establishes a boundary, where the generator is capable of receiving radio frequency signals. Also provided is a radio frequency device that sends radio frequency signals, the radio frequency device being capable of sensing the magnetic field and generating a radio frequency response.
Claims20
A collision avoidance system, comprising:
- a plurality of magnetic field generators adapted to generate, respectively, a first magnetic field and a second magnetic field;
- a controller configured to receive one or more response signals indicative of a strength of the first and the second magnetic fields, respectively, and to generate an alarm if the strength of the first magnetic field is above a first predetermined threshold and the strength of the second magnetic field is not above a second predetermined threshold.
