Patent BR-9910524-A (BR)
Inventor: BALLEY LLOYD STAN
IPC: G01F1/44
Filed: 1999-04-26
Abstract: A flow meter for use in an oil well has a central bore region in which an annular tube is fixed co-axially with the central bore region by a ring, which also seals the gap between the inner bore of the central bore region and the tube at its downstream end, thus forming a pocket open to the direction of fluid flow through the central bore region. The pocket brings the fluid to rest, thereby converting all of the dynamic pressure of the fluid into static pressure. This has the effect of maximizing the pressure differential obtainable between the central bore region and a position upstream of the tube, which allows an electronic calculation to be made to provide a more accurate flow rate measurement than would have been possible without the pocket.

Title: Dynamically adaptive observability coatings system
Inventor: HAWKE ANDREW JAMES
IPC: F41H3/00
Filed: 2000-04-07
Abstract: An object, such as an aircraft, may be camouflaged or made highly visible by re-defining its appearance in relation to its background. Camouflaging is achieved by capturing the obscured image behind the object in relation to an observer's position and displaying the hidden image on the surface of the object which faces the observer. By capturing multiple images from all directions around the object, and covering the surface of the object with the images captured from the opposite side, the capability of observers at any direction to distinguish the object is reduced. To make the object highly visible, previously stored library images may be displayed on the surface of the object. These may include bright colours, advertisements or logos (see <B>fig.3</B>). Suitable LCD technology is also discussed, including <1mm thickness plastic cholesteric LCD's.

Title: Detection system for determining position and orientation of objects
Inventor: JONES ALAN HENRY
IPC: G01S15/87
Filed: 1997-12-04
Abstract: The system tracks the position of each of a plurality of objects by determining the transit time of ultrasound signals from a transmitter on each object to a plurality of ultrasound receivers positioned at fixed points and computing therefrom the distance of the transmitter from the receivers. The ultrasound transmissions are initiated by radio signals from a master transmitter. Each ultrasound transmitter/radio receiver combination on an object is referred to as a transponder. The system can adapt to different numbers of transponders and differing demands for service (eg frequency of position determination per transponder-transmitter). A control system is provided for determining the order in which the object mounted transponder-transmitters are to be triggered by the radio transmissions, in response to updatable information relating to the objects and related service demands. The control system may include a memory for storing information about the different transponders with reference to their radio addresses, by which the order can be determined. The system can also determine object orientation by monitoring the positions of two transponders at spaced apart locations on an object and comparing their positions. It is preferable to address the two or more transponders on the object in succession.

Title: Tunable semiconductor laser
Inventor: TOMBLING CRAIG
IPC: H01S5/323
Filed: 2000-11-28
Abstract: A tunable semiconductor laser comprises a propagation region 100 in which a waveform (e.g. 14a) can exist, the propagation region comprising sequential gain regions 16 and control regions 114, the gain region 116 comprising a light amplification region supplied by a source of excitation, and the control region comprising a periodic structure through which the waveform propagates. The control region can be linked to a source of current thereby to enable changes to be made to the refractive index thereof. It is preferred that the material of the propagation region is (Ga,ln)(N,As). As a result, in the gain region the waveform will be less tightly confined and hence a higher gain can be produced without suffering from saturation of the gain material. Ideally, there will be tight confinement of the waveform in the control region to allow maximum advantage to be made of the change in refractive index. This can be achieved by controlling the physical configuration of the control region, such as by forming the propagation region with a lesser transverse width in the control region, and/or including non-semiconducting regions to confine the waveform. One way of achieving the latter is to include Al-containing layers in the propagation region, oxidising to produce Al<SB>2</SB>O<SB>3</SB> in layers 108'.

Title: Diagnosing a fuel tank condition
Inventor: SEALY BRENT EDWARD
IPC: F02M25/08
Filed: 2001-07-20
Abstract: A method is presented for diagnosing a condition in a fuel vapour purge system. An engine 200, fuel tank 210 and carbon canister 230 are connected in a three-way connection. The engine 200 can be selectively isolated by a purge control valve (270, figure 3), and the fuel tank 210 can be selectively isolated by a fuel tank control valve (250, figure 3). The operation of both valves is coordinated by an electronic engine controller 120. By isolating the fuel tank 210 and comparing the actual rate of change of the internal tank pressure (from the tank pressure sensor 260) to the estimated rate of change (from engine operating conditions eg bulk fuel temperature) it is possible to determine if a condition (eg missing fuel cap) occurred, and whether it is in the tank or in the vapour purge lines.
