Abstract
A magnetic communication system utilizing a multi-conductor transmit antenna is provided. Each of the conductors is supplied with an identical signal such that the magnetic fields generated by each conductor add together to create a like signal having an increased strength. Individual energy barriers are operatively connected to each conductor element in order to limit the current supplied to each conductor to intrinsically safe levels.
Claims18
A magnetic communications system, the system comprising:
- at least one signal source for providing a communications signal;
- a transmitting antenna comprising a plurality of conductors coupled to said at least one signal source;
- and
- at least one current barrier configured to limit the current supplied from the at least one signal source to the plurality of conductors.
A fault-tolerant communication system, the system comprising:
- a signal source;
- a plurality of amplifiers coupled to said signal source;
- a plurality of current barriers, each one of said current barriers coupled to a respective output of a corresponding one of said plurality of amplifiers;
- and
- an antenna, said antenna comprising a plurality of conductors, each conductor operatively connected to a respective one of said current barriers and amplifiers.
A method for providing intrinsically safe magnetic communication, the method comprising the steps of:
- generating a communications signal;
- amplifying said communications signal;
- providing said amplified communications signal to an antenna, said antenna comprising a plurality of conductors for generating a plurality of magnetic fields, and
- generating a magnetic communications signal by adding each of said plurality of magnetic fields.
