Abstract
Description
Abstract: A communication device for use in liquids or in adverse weather conditions includes a transceiver for transmitting and receiving communication signals, an antenna made of a self-passivating material exposed to the underwater environment, and a communication cable for transmitting communication signals between the transceiver and the antenna. The antenna is built into or attached to the hull of a vessel. This communication device can be integrally formed with or attached to clothing, protective layers, or coverings worn by the user.
Claims
LISTING OF THE CLAIMSWhat is claimed is:
1. A communication device comprising: a transceiver configured to at least one of transmit and receive communication signals; an antenna exposed to a submerged ambient environment and formed at least in part from a self-passivating material, the antenna being configured to at least one of wirelessly transmit and receive the communication signals; and a communication cable configured to transfer the communication signals between the transceiver and the antenna.
2. The communication device of claim 1, wherein the antenna is built-in or attached to an exterior hull portion of an aquatic vessel.
3. The communication device of claim 2, wherein the antenna conforms to the contour of the exterior hull portion of the aquatic vessel.
4. The communication device of claim 1, wherein the antenna is integral with or attachable to a garment, a protective layer, or a covering worn by a user.
5. The communication device of claim 1, wherein the antenna is a patch antenna, a whip antenna, a planar bow-tie antenna, or a blade antenna.
6. The communication device of claim 1, wherein the antenna is a first antenna of a plurality of antennas, wherein the communication cable comprises a splitter to deliver a centralized reference signal to the plurality of antennas.
7. The communication device of claim 1, wherein the transceiver comprises a transmitter for transmitting the communication signals to a remote receiver and a receiver for receiving the communication signals, wherein at least one of the transmitter and the receiver is underwater.
8. A method of communicating with a communication device, the method comprising: transferring a transmission radio frequency (RF) signal from a transceiver to an antenna that is exposed to a submerged environment or to an exterior ambient environment and formed at least in part from a self-passivating material; transmitting the RF signal via the antenna; receiving a received RF signal via the antenna; and transferring the received RF signal to the transceiver.
9. The method of claim 8, further comprising: submerging the antenna in a fluid to form an insulating layer on the surface of the antenna to prevent short-circuiting during at least one of transmitting and receiving of the RF signal.
10. A wearable communication device comprising: a transceiver configured to at least one of transmit and receive communication signals; an antenna formed at least in part from a self-passivating material, the antenna being attached to an exterior of apparel worn or carried by a user and exposed to atmosphere, the antenna being configured to at least one of wirelessly transmit and receive the communication signals; and a communication cable configured to transfer the communication signals between the transceiver and the antenna.
11. The wearable communication system of claim 10, wherein the antenna is integral with or attachable to a garment, a protective layer, or a covering worn by a user.
12. The wearable communication system of claim 11, wherein the antenna is mounted to the garment, the protective layer, or the covering by sew in, hook and loop pads, adhesive, or rivet.
13. The wearable communication system of claim 10, wherein the antenna is flexible to conform to a contour, bend, or fold of the garment or the covering.
14. An underwater communication device comprising: a transceiver arranged in a waterproof environment and configured to at least one of transmit and receive communication signals; an antenna that is formed at least in part from a self-passivating material and that is exposed to a submerged environment, the antenna being configured to at least one of wirelessly transmit and receive the communication signals; and a communication cable configured to transfer the communication signals between the transceiver and the antenna.
15. The underwater communication device of claim 14, wherein the antenna is built-in or attached to an exterior hull portion of an aquatic vessel.
16. The underwater communication device of claim 15, wherein the antenna conforms to the contour of the exterior hull portion of the aquatic vessel.
17. The underwater communication device of claim 14, wherein the antenna is integral with or attachable to a garment, a protective layer, or a covering worn by a user.
18. The underwater communication device of claim 14, wherein the antenna is a patch antenna, a whip antenna, a planar bow-tie antenna, or a blade antenna.
19. The underwater communication device of claim 14, wherein the antenna is a first antenna of a plurality of antennas, wherein the communication cable comprises a splitter to deliver a centralized reference signal to the plurality of antennas.
20. The underwater communication device of claim 14, wherein the transceiver comprises a transmitter for transmitting the communication signals to a remote receiver and a receiver for receiving the communication signals, wherein at least one of the transmitter and the receiver is underwater.21 . The underwater communication device of claim 14, wherein the antenna provides at least one of communication from a first diver to a second diver, communication from the first diver to a surface vessel, and communication from the first diver to a shore station.
22. The underwater communication device of claim 14, wherein the antenna provides communication using at least one of a remote microphone and a hydrophone.
23. The underwater communication device of claim 14, wherein the antenna provides at least one of communication between a first submarine and a second submarine, communication between the first submarine and a surface vessel, and communication between the first submarine and a shore station.
24. The underwater communication device of claim 23, wherein the antenna provides at least one communication between the first diver or the first submarine and an underwater structure.
