Title: Electromagnetic surveying for hydrocarbon reservoirs
Inventor: MACGREGOR LUCY M
IPC: G01V3/12
Filed: 2003-06-10
Abstract: A method of electromagnetic surveying of an area of seafloor that is thought or known to contain a subterranean hydrocarbon reservoir (12) includes, broadcasting an EM signal from a horizontal electric dipole (HED) transmitter (22) and obtaining vertical electric dipole (VED) response data at a remote receiver (35) in response thereto. Survey data are analysed by comparing the VED response data with background data which are not sensitive to the postulated hydrocarbon reservoir. Differences between the VED response data and the background data allow for the identification of buried hydrocarbon reservoirs. The background data may be provided by magneto-telluric surveying, controlled source electromagnetic surveying or from direct geophysical measurement. Using VED response data in this way, surveys may be performed in shallower water than has previously been possible since the VED detector is not sensitive to air-wave components of the EM field induced by the HED transmitter at the VED detector. A method of planning a survey includes modelling the VED response to HED transmitted signals.

Title: Steel tube flying lead jumper connector
Inventor: BARRATT RICHARD K O
IPC: E21B33/038
Filed: 2003-07-29
Abstract: A jumper (11) for transferring fluids from an umbilical to a subsea tree assembly has a plurality of steel tubes (27). The steel tubes are bent so that the jumper (11) is in a serpentine or w-shape while in a natural state. The steel allows and resists damage to the jumper (11) from the fluids and chemicals being transferred to the tree assembly. The w-shape of the jumper allows the jumper (11) to be stretched or contracted so the distance between the connectors (19, 23) on each end of the jumper can vary. The contracted width jumper (11) is attached to a terminal plate located on the tree assembly (15) as it is landed on a subsea wellhead. An ROV disconnects the jumper (11) and connects the jumper to receptors on the tree assembly and the umbilical (13), while stretching the jumper (11) to the necessary length to reach receptors. The jumper can be disconnected from the tree (15) assembly when maintenance is necessary without moving the umbilical (13).

Title: Centrifugal clutch which is rotationally balanced when engaged
Inventor: CHEVALIER JOHN PHILLIP
IPC: F16D3/68
Filed: 2005-03-07
Abstract: A centrifugal clutch comprises a centrifugal slider 302 with a massive enlargement 320 on one end and another massive enlargement 321 on an opposite end which rotationally balances the other massive enlargement 320 when the clutch is engaged. The centrifugal slider 302 is constrained by rails to slide across a channel formed diametrically across driving frame 301. Rotation of the frame 301 and slider 302 causes the massive enlargement 320 to pull the slider 302 radially from its retracted position to its extended position to cause first coupling dog 321 to engage second coupling dog 314, thereby driving gear 313. The frame 301, slider 302 and enlargements 320, 321 form a flywheel having a centre of inertia that is aligned with a rotational axis of the frame 301 when the slider 302 is in the extended clutch engaged position. In this position the frame 301, slider 302 and enlargements 320, 321 which form the flywheel are rotationally balanced. The frame 301 has tangential gaps in its rim into which the enlargements 320, 321 slide when in the engaged/disengaged position. In other embodiments there is limited rotational movement between the dogs 321, 314 and the clutch is used in an actuator which includes an electric motor, eg starter motor. There may also be viscous damping member for absorbing shock/backlash when the actuator hits a dead end.

Abstract: Decoding low-density parity-check (LDPC) codes using an iterative decoding structure where for each iteration (referring to Fig. 3b), a plurality of bit nodes and a plurality of check nodes are updated <B>302</B>. For each bit node, a set of check node messages are used for updating that bit node and for each check node <B>306</B> a set of bit node messages are used for updating that check node <B>306</B>. In each check node update <B>302</B>, selecting a first subset of bit node messages from the set of bit node messages used for updating each check node <B>306</B> and selecting a first algorithm for use in updating a first subset of check node messages corresponding to the first subset of bit node messages. Identifying a second subset of bit node messages, excluding the first subset of bit node messages, used for updating the check node <B>306</B>, and selecting a second algorithm for use in updating a second subset of check node messages corresponding to the second subset of bit node messages. The first subset of bit node messages may include a set of most contributing bit-node messages, or the smallest bit node messages, or least reliable bit node messages. A more computationally-demanding algorithm may be used in association with the most contributing bit nodes in the check node update process. The remaining bit nodes and their messages may be updated using a less computationally-demanding algorithm.

Title: Transdermal drug delivery device with latch
Inventor: CHOWDHURY DEWAN FAZLUL HOQUE
IPC: A61K9/70
Filed: 2006-02-04
Abstract: A transdermal drug delivery device comprises a reservoir layer 10, which comprises one or more chambers for containing a drug and apertures in fluid communication with the chambers, through which the drug may be delivered to the skin of a patient. An electromechanical actuator 18 is operable to move the apertures from an open state to a closed state or vice versa and a latch holds the apertures in one of the two states without continued operation of the electromechanical actuator 18. Use of the latch allows the apertures to remain open for extended or indefinite periods without expending energy, whereby a smaller power source may be used and whereby regimes requiring the slow delivery of drugs over long periods can be accommodated.

Title: Fiber optic sensor system
Inventor: POLAND STEPHEN H
IPC: G01N/
Filed: 2004-09-02
Abstract: A fiber optic system (10, 210) including a plurality of optical sensors, each with an identification system (20, 120, 220, 320). The fiber optic system (10) includes a fiber (12, 112) extending a distance, a demodulator (14), and at least one coupler (16, 116), optical sensor (18, 118) and corresponding identification system (20, 120). The identification system (20, 120) is powered by light shunted from the fiber (12, 112) by the coupler (16, 116) to a modulating device (24, 124). The modulating device (24, 124) modulates the light and transmits it to a power converting device (16, 116), which transforms the light energy into electrical energy. The electrical energy powers a high temperature integrated circuit (28, 128) upon which is stored a digital identification of a respective optical sensor (18, 118). The integrated circuit (28, 128), upon being powered up, sends a modulated response (30, 130) back up to the surface through the modulating device (24, 124). Alternatively, a passive identification system (210) is described, where reflective devices (220, 320) are placed at pre-determined locations along the length of the fiber (212, 312). As the optical beam passes through the reflective devices (220, 320), identification information for a sensor (218, 318) is encoded onto the beam. An optical frequency domain reflectometer (214) generates the optical beam and detects the encoded information.

IPC: H05B41/282
Filed: 2005-02-09
Abstract: A method of improving the efficiency of an inverter which supplies power to a load, in particular a cold cathode fluorescent lamp (CCFL), has the steps of controlling a plurality of switches to generate an alternating current in response to a direct current input, filtering the alternating current before output to the load, detecting a zero-crossing of the alternating current output, and delaying the controlling of the plurality of switches so as to maintain a constant switching frequency despite changes in the direct current output. The plurality of switches may be controlled by adjusting the time that each switch is in the off or the on state.
