20080204335 | TANK ANTENNA - An air tank for a self-contained breathing apparatus that incorporates a coil antenna for use in a magneto-inductive system. The coil antenna is formed as a part of the tank. The antenna is embedded within the sidewall of the air cylinder to form the air tank. The self-contained breathing apparatus may include a magneto-inductive device operatively connected to the coil antenna for conducting magneto-inductive communications. A microphone and speaker or headset may be included to facilitate voice communications over the magneto-inductive system. | 08-28-2008 |

20090315791 | Downhole Component with an Electrical Device in a Blind-hole - A downhole tool string component has a through-bore intermediate first and second tool joints adapted for connection to adjacent tool string components. A blind-hole is formed in an outer surface of the component. A processing unit is also disposed within an outer surface of the component. An electrical device that is disposed within the component is in communication with the processing unit through an electrically or optically conductive medium which has a self-aligning pattern. | 12-24-2009 |

20100238078 | Transmission of underwater electromagnetic radiation through the seabed - An underwater communication method is provided. EM signals are transmitted via a seabed using an underwater electrically insulated magnetically coupled antenna. By making use of the low loss properties of the seabed, EM signal attenuation can be reduced and consequently the transmission range can be increased. The underwater electrically insulated magnetically coupled antenna may be located within a body of water or may be buried in the seabed. | 09-23-2010 |
20110163926 | DEVICE FOR PROPAGATION OF ELECTROMAGNETIC WAVES THROUGH WATER - The invention concerns a device ( | 07-07-2011 |
20130120199 | VAULT ANTENNA FOR WLAN OR CELLULAR APPLICATION - A fringe-effect antenna module includes coupling structure configured to couple the module to a communications vault that is disposed substantially at ground level. A support structure (which preferably includes an electronics unit) is coupled to the coupling structure, and at least one antenna element is coupled to the support structure. A metallic deflector is coupled to at least one of (i) the coupling structure and (ii) the support structure. The metallic deflector has an edge that is positioned substantially parallel to the ground so as to cause a fringe effect upon the RF signals of the antenna to cause those RF signals to bend in a direction toward the ground. | 05-16-2013 |
20130321223 | Underwater Connector Arrangement - An underwater connector includes a first component and a second component, wherein the components are operable to be coupled together in operation in a first coupled state, and operable to be mutually spatially separated in a second uncoupled state. The first and second components each include communication arrangements which are operable to provide wireless communication between the first and second components when in their first coupled state. The first and second components include a power transfer arrangement for transmitting power between the first and second components. The power transfer arrangement includes inductive coupling devices and/or capacitive coupling devices, wherein the power transfer arrangement is implemented substantially as an annulus, for example circular, elliptical, or polygonal, on the first and second components together with the communication arrangements being disposed within the annulus and/or around a periphery of the annulus. The wireless communication is operable to occur using a wireless signal whose carrier frequency is within a frequency range of 300 MHz to 300 GHz, wherein the wireless communication is implemented using microwave and millimeter wave technologies. | 12-05-2013 |
20140306853 | Antenna for Use in a Downhole Tubular - An antenna for use in a downhole tubular. The antenna comprises a generally cylindrical housing and a coiled conductor located within a portion of the housing and separated therefrom by insulating material. The portion of housing has a greater internal diameter than an external diameter of the coiled conductor. | 10-16-2014 |
20150102967 | UNDERWATER ANTENNA DEVICE WITH A NON-STATIONARY ANTENNA AND UNDERWATER VESSEL - The invention relates to an underwater antenna device with a nonstationary antenna, an extension mechanism and a repositioning mechanism, wherein an extending force can be applied in a direction of the extending force by the extension mechanism of the antenna and an opposing force can be applied in a direction of the opposing force, in the opposite direction to the extending force by the repositioning mechanism of the antenna, characterized in that the repositioning mechanism or a part of the repositioning mechanism is designed as selectively nonstationary, so that, by selected changes to the position, the antenna can be positioned in a retracted position, an extended position or an intermediate position. | 04-16-2015 |
