Title: On-off switching of a low noise amplifier in sleep and receive modes to detect and validate a wake up signal
Inventor: HAN DONG OK
IPC: H04W52/02
Filed: 2006-12-06
Abstract: A low-power wireless communication apparatus comprises a low-noise amplifier 203 for amplifying a radiofrequency signal, a wake up signal detector 205 for receiving the amplified radiofrequency signal and a controller 210 for providing a predetermined ON/OFF control signal to the low noise amplifier 203, wherein in a sleep mode corresponding to a receive waiting state, the predetermined control signal controls the low noise amplifier 203 (and preferably the wake up signal detector 205) to operate at a predetermined on-off duty ratio and where, when a wake up signal is detected in the sleep mode, the apparatus is switched to a receive mode where the low-noise amplifier 203 is maintained in an on state. Switches 202, 204 may be used to connect the antenna 201 and low noise amplifier 203 to the wake up signal detector 205 in the sleep mode and to the receiver 206 in the receive mode. The detection of a wake up signal in the sleep mode preferably comprises amplifying, rectifying and integrating the signal to see if it exceeds a predetermined threshold (Figure 3). The detected signal may then be deemed valid if a valid data packet is received in the receive mode, enabling the apparatus to wake up to perform transmit and receive operations. The apparatus returns to the sleep mode, directly or after a predetermined off mode, when transmit and receive operations are complete or when the detected wake up signal is deemed invalid (Figures 4 and 7b). The on-off duty ratio may be set depending on the communication environment. Power is saved by controlling the on/off operation of different components in the sleep, receive, transmit and off modes (Figure 5).

Title: Interleaved bi-static interferometric synthetic aperture radar technique for determining height information for an imaged area
Inventor: HUTCHINSON TREVOR
IPC: G01S13/90
Filed: 2007-02-15
Abstract: A method and apparatus is provided for determining the height information of an imaged area A, utilising two platforms 42',42'' configured to carry out an interferometric synthetic aperture radar (InSAR) technique. The two platforms 42',42'' are separated by a known distance H and are moving in substantially the same direction at a similar speed. Radar pulses are transmitted at regular intervals alternately by each platform 42',42'' and the transmitted pulses are received by both platforms 42',42''. The reflected pulse energy is processed at both platforms 42' ,42'' to generate height information of the imaged area A.

Title: Process for fabricating a semiconductor package
Inventor: PAVIER MARCK
IPC: H01L21/60
Filed: 2007-03-30
Abstract: A process for fabricating a semiconductor package which includes using an exothermically active nanoparticle paste (10) to join an electrode (12) of a semiconductor die (14) to a support body (16, for example, a conductive clip. The die pad may be on an IMS or DBC. The nanoparticles may be less than 200nm in diameter and comprise silver, copper or bismuth or alloys of silver/copper, bismuth/silver, silver/aluminium, tin silver alloy, and tin/bismuth/copper ternary alloys. The exothermic reaction may be initiated using one of an infrared or ultraviolet source, a convection oven or a spark. Alternatively, an electrode of a semiconductor die may be coated with exothermically active nanoparticle paste, and a conductive support may also be coated with exothermically active nanoparticle paste. The exothermic reaction commences when the two coatings of nanoparticles are place in contact.

Title: Ball cock valve regulator
Inventor: HENSON DENNIS RAYMOND
IPC: F16K31/18
Filed: 2007-05-24
Abstract: An equilibrium valve (7) which is opened and closed by the movement of a float means (16, 17) secured at an end of a lever arm (8) and which rises and falls in use with the level of water in a container (11). The supply of liquid to the container is controlled by the valve (7) which has a discharge outlet (6) directing incoming water in a downwardly direction. The lever arm (8) is combined with a catchpot (5) into which incoming water is diverted. The catchpot (5) is mounted on or forms part of the arm (8) and includes a region which extends below the discharge outlet (6) of the valve (7) and includes a draining orifice (2) which aligns with the outlet (6) when the lever arm has dropped sufficiently to begin to open the valve. When the container is nearly full the buoyancy of the floats carries the lever arm and catchpot upwardly to close the valve. In doing so the catchpot empties, increasing the buoyancy effect and thereby closing the valve more rapidly and firmly.

Title: Friction heating apparatus comprising a rotating disc
Inventor: OLDHAM ADRIAN
IPC: E01C19/08
Filed: 2008-05-09
Abstract: A friction heating apparatus comprises a motor 6 connected via a shaft to a disc 3, where the shaft passes through a seal 5 into a chamber 2. The chamber has an inlet opening 1 and an outlet opening 4. Material to be heated, such as semi-solid bitumen, can be placed into the chamber through the inlet opening. The heated material can exit the chamber through the outlet opening. The seal resists the passing of material between the shaft and the chamber. The disc and chamber may be of a metal construction. Preferably, the disc is driven by an electric or hydraulic motor. In use, frictional heat is generated by the rotating disc to melt the material, the resultant hot liquid material being tapped off at the outlet opening.

IPC: B01D33/03
Filed: 2008-07-10
Abstract: A screen frame (10, Fig. 1), adapted for use in a shaker to separate solids from a liquid/solid mixture, generally mud used in drilling operations, to which woven wire mesh (12, Fig. 1) is to be attached, comprises a wire structure 20 with an outer perimeter and a plurality of plastic ribs (14, Fig. 1) extending between opposing regions of the perimeter.

Title: A nozzle for a refuelling probe
Inventor: MOUSKIS CHRISTOPHER
IPC: B64D39/04
Filed: 2009-01-21
Abstract: The nozzle of the invention comprises a nozzle body 104 having a nozzle tip 106, 22 for engaging a fuel hose coupling 44, 46, 48, the tip 106, 22 extending from the body 104, and a valve sleeve 26 for opening and closing a fuel path 54 between the tip 106, 22 and the body 104. The tip 106, 22 is mounted within the body 104 on a flexible shaft , so as to accommodate misalignment between the nozzle and the fuel hose coupling. This eliminates the need for a bearing at the end of the shaft, which causes a pressure drop in the nozzle. The shaft may additionally be axially slidable in the mounting in a first portion of the nozzle body, and may be held in the extended position of the tip by abutment with part of a second portion of the nozzle body. The first and second portions of the body are joined a weak link, which is frangible in the event of excessive load, to release the abutment and allow the nozzle tip to travel towards the body and close the fuel path. Thus a separate shut-off valve is not required. The invention also allows the inclusion of a pressure regulator sleeve for moving out of the nozzle body towards the nozzle tip in the event of excessive fuel pressure. Thus the nozzle tip can be tailor made to the aircraft to which it is fitted for providing suitable pressure regulation.

Abstract: An engine cylinder head 10 has a first camshaft 14 driven by the engine crankshaft via one output 18 of a phasing system 12 mounted to the camshaft 14. A second camshaft 22 is driven via a second output 20 of the phasing system 12, and two oil control valves 46, 48 are connected to the phasing system for enabling the phasing system to vary the timing of each camshaft independently with respect to the engine crankshaft in response to oil pressure signals from a respective one of the control valves. In the invention, oil feeds from each control valve 46, 48 enter the camshaft 14 via an oil feed journal 34, 36, and connect to the phaser 12 via four axially extending channels within the camshaft 14. The camshaft 14 may be hollow to receive a hollow insert 50 and three of the oil feed channels 54, 56, 58 may be formed by elongated grooves in the outer surface of the insert 50 in conjunction with the inner wall of the hollow camshaft 14 while the fourth oil feed channel 52 is the bore 52 of the insert 50.
