Abstract

An electromagnetic barrier includes a first surface and a second surface. A first transducer is coupled to the first surface. A second transducer is coupled to the second surface such that a signal is transmittable between the first transducer and the second transducer without physically penetrating the electromagnetic barrier.

First claim

What is claimed is:

1. A method for use in communicating through an electromagnetic barrier that includes a first surface and an opposing second surface, said method comprising:
coupling a plurality of first transducers to the first surface, the plurality of first transducers including a first interior transducer and a plurality of first peripheral transducers spaced circumferentially about the first interior transducer;
coupling a plurality of second transducer to the second surface, the plurality of second transducers including a second interior transducer and a plurality of second peripheral transducers spaced circumferentially about the second interior transducer, wherein the plurality of first peripheral transducers and the plurality of second peripheral transducers include at least one input transducer configured to operate only in a transmit mode by transmitting signals from the first surface to the second surface and at least one output transducer configured to operate only in a receive mode by receiving signals transmitted from the second surface to the first surface, wherein at least one of the plurality of second peripheral transducers is selectively steerable to communicate signals between the plurality of second peripheral transducers and multiple transducers of the plurality of first transducers, and wherein the first interior transducer includes an array of transducers that are each oriented to communicate with at least one of the plurality of second transducers; and
transmitting a signal between at least one of the plurality of first transducers and the at least one second transducer without physically penetrating the electromagnetic barrier.

2. A method in accordance with claim 1 further comprising transmitting a first signal from a signal generator positioned on a first side of the electromagnetic barrier towards the plurality of first transducers, the signal transmitted between the plurality of first transducers and the at least one second transducer associated with the first signal.

3. A method in accordance with claim 1 further comprising:
transmitting an originating signal from a signal generator positioned on a first side of the electromagnetic barrier towards a multiplexer positioned on the first side of the electromagnetic barrier; and
transmitting a selected signal from the multiplexer towards the at least one first transducer, the selected signal associated with the originating signal, the signal transmitted between the at least one first transducer and the at least one second transducer associated with the selected signal.

4. A method in accordance with claim 1 further comprising transmitting a conditioned signal from the at least one second transducer towards a sensor positioned on a second side of the electromagnetic barrier, the conditioned signal associated with the signal transmitted between the at least one first transducer and the at least one second transducer.

5. A method in accordance with claim 1 further comprising:
transmitting a raw signal from the at least one second transducer towards a controller positioned on a second side of the electromagnetic barrier, the raw signal associated with the signal transmitted between the at least one first transducer and the at least one second transducer; and
transmitting a conditioned signal from the controller towards a sensor positioned on the second side of the electromagnetic barrier, the conditioned signal associated with the raw signal.

6. A method in accordance with claim 1 , wherein the array of transducers includes a steerable transducer array, said method further comprising selectively steering at least one transducer of the array of transducers such that the at least one transducer is oriented to transmit the signal towards the at least one second transducer.

7. A communication device for use in communicating through an electromagnetic barrier that includes a first surface and an opposing second surface, said communication device comprising:
a plurality of first transducers coupled to the first surface, said plurality of first transducers including a first interior transducer and a plurality of first peripheral transducers spaced circumferentially about said first interior transducer; and
a plurality of second transducers coupled to the second surface, said plurality of second transducers including a second interior transducer and a plurality of second peripheral transducers spaced circumferentially about said second interior transducer, wherein said plurality of first peripheral transducers and said plurality of second peripheral transducers include at least one input transducer configured to operate only in a transmit mode by transmitting signals from the first surface to the second surface and at least one output transducer configured to operate only in a receive mode by receiving signals transmitted from the second surface to the first surface, wherein at least one of said plurality of second peripheral transducers is selectively steerable to communicate signals between said plurality of second peripheral transducers and multiple transducers of said plurality of first transducers, and wherein said first interior transducer comprises an array of transducers that are each oriented to communicate with at least one of said plurality of second transducers, such that a signal is transmitted between at least one of said plurality of first transducers and said at least one second transducer without physically penetrating the electromagnetic barrier.

8. A communication device in accordance with claim 7 further comprising a signal generator positioned on a first side of the electromagnetic barrier and configured to transmit a first signal towards said plurality of first transducers, the signal transmitted between the plurality of first transducers and the at least one second transducer associated with the first signal.

9. A communication device in accordance with claim 7 further comprising:
a signal generator positioned on a first side of the electromagnetic barrier; and
a multiplexer positioned on the first side of the electromagnetic barrier, said signal generator configured to transmit a first signal towards said multiplexer, said multiplexer configured to transmit a selected signal towards said at least one first transducer, the selected signal associated with the first signal, the signal transmitted between said at least one first transducer and said at least one second transducer associated with the selected signal.

10. A communication device in accordance with claim 7 further comprising a sensor positioned on a second side of the electromagnetic barrier and oriented to receive a conditioned signal from said at least one second transducer, the conditioned signal associated with the signal transmitted between the at least one first transducer and the at least one second transducer.

11. A communication device in accordance with claim 7 further comprising:
a controller positioned on a second side of the electromagnetic barrier and oriented to receive a raw signal from said at least one second transducer, the raw signal associated with the signal transmitted between the at least one first transducer and the at least one second transducer; and
a sensor positioned on the second side of the electromagnetic barrier and oriented to receive a conditioned signal from said controller, the conditioned signal associated with the raw signal.

12. A communication device in accordance with claim 11 , wherein said controller is configured to store capacitive energy.
