Patent GB-2435559-A (GB)
Title: A bit-flipping sigma-delta modulator with a ternary quantiser
Inventor: MAGRATH ANTHONY JAMES
IPC: H03M7/00
Filed: 2003-09-15
Abstract: A sigma-delta modulator for a class D audio amplifier has a three-level quantiser output suitable for driving a transistor bridge (figure 12). A bit-flipping mechanism reduces the frequency of output transistor switching in the bridge and hence improves efficiency, which is important in portable audio apparatus. The integrators Ila1 and Ila0 in the loop filter are adjusted when bit-flipping occurs. The controller C may decide not to enforce a bit flip if this would cause too much noise.

Title: A device for obfuscating visual information
Inventor: YATES HOWARD JAMES
IPC: G09C5/00
Filed: 2008-04-07
Abstract: A device is described for hiding and subsequently recovering visual information. Two or more tokens (1), each containing a mask (2,3) of coloured pixels (4), are overlaid (5), so that when the pixels are aligned, hidden information, invisible in the individual tokens, may be revealed. The tokens may be printed on various media, or may be displayed on an electronic device. The hidden information consists of one or more recognisable alphabetic, numerical or pictorial characters (6). During token overlay and alignment, the information becomes visible because it is made up of pixels whose colour is differentiated from the other pixels in the overlay. The information is hidden by adding pixels of certain colours. When the tokens are overlaid and the pixels aligned, the added pixels are effectively subtracted, revealing the hidden information. The methods used to achieve the pixel patterns and colours necessary to perform additive hiding and subtractive revelation of information may be automated.

Abstract: A switching device comprising a plurality of ingress ports and egress ports, an ingress arbiter for selecting data packets from at least one buffer as candidate data packets for forwarding to an egress port, and an ingress scheduler for scheduling transmission of selected ones of the candidate data packets to destination egress ports. Aspects of the invention include the switching device arranged to determine a first time at which a first cell of a selected data packet selected by an ingress arbiter is to be forwarded to one of the egress ports, determine a further time at which a further cell of a selected data packet is to be forwarded to one of the egress ports (i.e. a ingress scheduler), forward the cells at the determined times. This invention provides a switching device which is arranged to determine both a first time at which a first cell should be forwarded and at least one further time at which a further cell should be forwarded. In this way a single scheduling operation is provided which allows times at which a plurality of cells are to be forwarded to be determined.

Title: Monitoring of components of a gas mixture in a reduced pressure environment
Inventor: BLACK JOHN DAVID
IPC: G01N21/35
Filed: 2008-12-09
Abstract: A device 1 for monitoring components of a gas mixture has a gas cell 4 for receiving a sample of the gas mixture. The device 1 also has an infrared radiation source 8 which delivers infrared radiation into the cell 4 for transmission through the sample, the transmitted infrared radiation being absorbed by components of the gas mixture at absorption wavelengths which are characteristic of those components. The device also has an infrared detector 9 which measures the transmitted infrared radiation, thereby enabling the monitoring of components of the gas mixture in the sample. The device 1 is connectable to a gas source 2 from which the cell 4 receives the sample. The device 1 further has a system 5, 7 for reducing the pressure of the sample in the cell 4 relative to the pressure of the source 2. Rapid reduction of pressure can cause significant expansion cooling of the sample.

Title: Drogue adapter for a refuelling boom of an aerial refuelling apparatus
Inventor: MOUSKIS CHRISTOPHER
IPC: B64D39/00
Filed: 2009-04-20
Abstract: The adapter comprises a linkage arm 36 between the boom 34 and a hose 38 and drogue 40 arrangement, which arm can be pivotally moved about the boom to adjust the position of the hose and drogue and take up hose slack by providing a biasing force on the hose. The arm 36 carries fluid channel, has respective bearings to provide a swivel mounting in an aperture at a distal end 32 of the boom and a swivel attachment to a proximal end of the hose 38, and an associated motor and gearbox for rotation at the boom end bearing. For take-off and landing, the arm 36 is pivoted relative to the boom 34 so that its hose end is above the boom to increase hose 38 and drogue 40 clearance above the ground. For refueling using just the boom 34, the arm 36 is pivoted to move its hose end even further forward above the boom end 32. For refueling using the drogue 40, the arm 36 is pivoted downwardly with the hose end below the boom 34 to provide biasing to counter aerodynamic forces on the hose 38 and drogue 40.
