| 20080260539 | Apparatus and Method For Controlling Supply of Barrier Gas in a Compressor Module - An apparatus for controlling the supply of barrier gas to a compressor module includes a pressure housing containing an electric motor which via a shaft is drivably connected to a compressor. The shaft is supported by magnetic bearings and at least one axial seal around the shaft which divides the pressure housing into first and second compartments including the motor and compressor, respectively. The second compartment has fluid inlet and outlet. A line is fluid-connected to the first compartment for barrier gas from a reservoir, with a flow restriction element between the reservoir and first compartment. The apparatus facilitates a method for controlling the supply of barrier gas based on gas velocity through the seal and pressure in the second compartment. An overpressure can be set in the reservoir. A controlled supply of barrier gas to at least the first compartment is effected via flow restriction in the feed pipe. | 10-23-2008 |

| 20090007834 | Controlled Deterioration of Non-Reinforced Concrete Anchors - A concrete formulation, which undergoes controlled deterioration in water, that can be used for making anchors for releasably tethering submarine devices at the seabed. The anchor may have handles for a device release mechanism or a central hole for a central device release mechanism. The formulation includes additives, which cause the cement to transform into non-binding Thaumasite over a pre-set period of time, leaving only natural material on the seafloor. | 01-08-2009 |
| 20100061187 | POSITIONING SYSTEM - A passive listening acoustic system and method of use may include source means for providing continuous, pulsed, or pulse coded acoustic signals at two or more frequencies and at least two acoustic sensors or hydrophones which detect and record a signal for use within a Seabed Logging system to determine the position and/or orientation of instruments in the system. | 03-11-2010 |
| 20100231223 | INSTRUMENT FOR MEASURING ELECTROMAGNETIC SIGNALS - A device and method for measuring electromagnetic signals that can be used to take measurements at or near the sea floor. The device comprises a central housing, a data management system located within the housing and at least two arms extending outwards from the housing. Each arm comprises a flexible elongate sheath attached to the housing, a sensor head, a flexible electrical cable attached to the sheath and connecting the sensor head to the data management system and a rod which is removeably locatable within the sheath. The rod is connectable relative to the housing at one end and connectable relative to the sensor head at the end remote from the housing. | 09-16-2010 |

| 20110157300 | METHOD AND SYSTEM FOR DETERMINING A DIRECTION BETWEEN A DETECTION POINT AND AN ACOUSTIC SOURCE - A method including: receiving acoustic signals originating from an acoustic source at a first pair of microphone elements, arranged symmetrically about a detection point; calculating, with a processor device, a cross correlation of signals provided by the first pair of microphone elements, resulting in a first cross correlation signal; receiving the acoustic signals originating from the acoustic source at a second pair of microphone elements, arranged symmetrically about the detection point; calculating, with the processor device, a cross correlation of signals provided by the second pair of microphone elements, resulting in a second cross correlation signal; and calculating, with the processor device, a direction between the detection point and the acoustic source based on a convolution of the first cross correlation signal by the second cross correlation signal. | 06-30-2011 |

| 20090036794 | METHOD AND APPARATUS FOR DETERMINING LOCAL TISSUE IMPEDANCE FOR POSITIONING OF A NEEDLE - The invention relates to apparatus and methods for measuring local tissue impedance for subcutaneous tissue surrounding a needle tip inserted into a subject, impedance spectra and/or complex impedance values are determined. The invention applies a monopolar impedance measuring setup with a needle, a current-carrying electrode, an optional reference electrode. The setup is configured to eliminate contributions from the current-carrying electrode in order to measure local impedance of tissue in the close neighbourhood of the needle tip instead of an averaged value over the volume or current path between the needle and the electrode(s). The determined impedance can be correlated with either a tissue type or state, or with a position of the needle tip in the subject, and can thereby provide an insertion history to the operator in the form of impedance or corresponding tissue type as a function of insertion depth or time. | 02-05-2009 |
