Title: Traction control system for a vehicle
Inventor: MASKELL ANDREW GAVIN
IPC: B60K28/16
Filed: 2007-02-12
Abstract: When it is detected by velocity sensors (1-4, figure 1) that the vehicle is stationary 14 a slip threshold is set 15 by the controller (6, figure 1) to a low value so that virtually no wheel slip is allowed. Once the speed of the vehicle has reached a predetermined value, a higher wheel slip threshold is set 17 so that the vehicle's forward momentum can be maintained. This permits the vehicle to move off from rest without the wheels digging into a deformable surface, for example by controlling the throttle of the vehicle's engine (12, figure 1).

Title: Hydraulic set permanent packer with isolation of hydraulic actuator and built in redundancy
Inventor: FAY PETER
IPC: E21B23/06
Filed: 2005-08-24
Abstract: A packer (30) includes one or more anchors (36, 38) for securing the packer in a wellbore and a pair of seal elements (34,40) that form a fluid seal. The packer assembly is hydraulically set (41) and, thus, it can be located at any desired position within the wellbore, i.e. not necessarily immediately atop the liner hanger. The packer assembly is secured within the wellbore by a staged setting process through use of shear pins (60) that have increasingly stepped shear values. Redundancy in packer sealing is provided by the use of two seal elements to establish fluid sealing. The design of the packer assembly also provides hydraulic isolation of the actuating portions of the packer assembly upon setting and maybe used for a tie back string.

Title: System and method for controlling wellbore pressure during gravel packing operations
Inventor: CONTANT MATTHE
IPC: E21B43/04
Filed: 2007-03-08
Abstract: A technique is provided to facilitate gravel packing in a well 20. A conduit 38 surrounded by a screen 32 is deployed in an isolated lower wellbore region 24. The conduit cooperates with one or more valves 52 that can be selectively opened to relieve wellbore pressure resulting from advancement of the gravel packing beta wave 58 during the gravel packing procedure. A control system 54 enables dependable and timely opening of the one or more valves 52 to relieve wellbore pressure and protect the surrounding formation from fracturing. An electromagnetic telemetry system operatively coupled to the valve assembly or an electronic system using two pressure sensors coupled to the valve assembly may be utilised.

Title: Vapour measurement in a fuel injector
Inventor: SMITHER BENJAMIN DAVID
IPC: F02D41/04
Filed: 2007-09-20
Abstract: An internal combustion engine has a fuel injector which comprises a sprung piston (55) and an electrical coil (57) for displacing the piston (55). The piston draws fuel into and expels fuel from a pumping chamber (52). The number of operations of the injector per engine cycle is controlled by an electronic controller (23) to control the quality of fuel delivered per cycle to a combustion chamber. A voltage measured in the coil (52) by movement of the piston under action of the spring is used to give an indication of vapour pressure of the fuel. A device akin to the injector can be used to draw fluid from a pipeline to test the fluid.

Title: Determining shortest path through a network
Inventor: REEVE ANDREW
IPC: H04B1/74
Filed: 2006-09-11
Abstract: A shortest path is determined through a network between source and destination nodes. The source node (A) broadcasts a path request message which propagates through the network. Intermediate nodes receiving the message for the first time store a hop count and broadcast identifier contained in the message, and subsequent request messages received from the source are only propagated if the hop count of the subsequent message is less than the stored count. The destination node (Z) returns a message to the source node indicating the path received with the shortest hop-count.

Title: Miniature non-directional microphone
Inventor: MILES RONALD N
IPC: B81B3/00
Filed: 2007-10-11
Abstract: A miniature microphone comprising a diaphragm compliantly suspended over an enclosed air volume having a vent port is provided, wherein an effective stiffness of the diaphragm with respect to displacement by acoustic vibrations is controlled principally by the enclosed air volume and the port. The microphone may be formed using silicon microfabrication techniques and has sensitivity to sound pressure substantially unrelated to the size of the diaphragm over a broad range of realistic sizes. The diaphragm is rotatively suspend for movement through an arc in response to acoustic vibrations, for example by beams or tabs, and has a surrounding perimeter slit separating the diaphragm from its support structure. The air volume behind the diaphragm provides a restoring spring force for the diaphragm. The microphone's sensitivity is related to the air volume, perimeter slit, and stiffness of the diaphragm and its mechanical supports, and not the area of the diaphragm.
