Title: Decoding LDPC-coded data
Inventor: LESTABLE THIERRY
IPC: H03M13/11
Filed: 2007-07-27
Abstract: A decoder decodes an incoming data signal in accordance with an error correction code. The decoder is operable to perform a plurality of decoding operations to decode the incoming data, each decoding operation using a different representation of a parity check matrix for the error correction code corresponding to a respective different non-binary Tanner graph (5a-5c). The multiple representations of the parity check matrix are possible if the code is formed over an Abelian group. The operations may be performed in sequential order (if the first operation does not produce a suitable convergence) or in parallel (fig.2, not shown). Application to LDPC codes (using e.g. a belief propagation algorithm) but also to, e.g.. turbo and BCH codes.

IPC: F02C9/28
Filed: 2007-09-25
Abstract: A swirler 2, for use in a burner of a gas turbine engine, has a series of vanes 9 arranged in a circle, and with flow slots 15 defined between adjacent vanes in the circle. The flow slots have inlet ends 12 and an outlet ends 14, and in use air flows along the slots from inlet to outlet ends and liquid fuel is supplied from at least one fuel injection port 10, such that a swirling mix of air and fuel is provided at the outlet ends of the flow slots. At least one flow slot also has a bleed hole 51 and an associated control unit 4, whereby air/fuel can be bled from the slot in dependence on the load on the gas turbine engine. The control unit may be arranged to open the bleed hole during part-load operation, and close the bleed hole as full load operation is approached. Each flow slot may also have additional bleed holes (63, 65 fig 5), and the fuel injection port may be located adjacent the outlet end of the at least one flow slot. The invention assists in achieving a more uniform distribution of fuel droplets, such as at part-load engine conditions.

Abstract: A sensor 100 includes a piezoelectric substrate 102 and conductive elements 104a-104b formed in or over the substrate. The sensor also includes a sensing layer 108 formed over the substrate. The sensing layer has one or more properties (such as a mass loading, an electrical property, or a visco-elastic property) that vary based on at least one measurand to be measured by the sensor (such as carbon dioxide(CO2)).

The sensing layer includes a combination of polyaniline and carbonic anhydrase. The combination of polyaniline and carbonic anhydrase could be formed using an emeraldine base. For instance, an aniline can be dissolved in water to form a mixture, and hydrochloric acid and an oxidant can be added to the mixture. A chemical polymerization of the aniline in the mixture can be performed to form polyanilne.

Title: Digital filter arrangements for ambient noise-reduction
Inventor: CLEMOW RICHARD
IPC: G10K11/178
Filed: 2006-04-12
Abstract: A digital circuit arrangement for an ambient noise-reduction system uses a low latency signal processing chain. The circuit arrangement includes an analogue-to-digital converter 81, a digital processor including digital filter 82, ideally a digital delta-sigma modulator 83, and a digital-to-analogue converter 84. The arrangement converts analogue ambient noise signals, collected by microphone 13, into digital signals and then subjects the converted signals to digital filtering. Preferably, the digital signals are N-bit digital signals at sample rate f0, where the value of N in some embodiments no greater than 8, and fomay be 64 times the Nyquist sampling rate but, in any event. This permits digital processing to be used without incurring group delay problems that rule out the use of conventional digital processing in this context. Furthermore, adjustment of the group delay can readily be achieved, providing the ability to fine tune the group delay for feed-forward applications.

Title: Material sensitive to light or heat
IPC: G03C1/494
Filed: 1940-06-12
Abstract: 543,940. Cellulose conversion products. KODAK, Ltd. (Eastman Kodak Co.). June 12, 1940, No. 10225. [Class 2 (ii)] [Also in Group XX] A cellulose sheet is made sensitive to light or heat by converting it superficially into a cellulose carboxylic acid by oxidation, and then converting the oxidized layer to a waterinsoluble metal salt, the term "metal" including ammonium and elements such as tellurium which form salts in the manner of a metal. In a modification cellulose fibre is oxidized and coated on a support as of paper, and the coating is converted into a water-insoluble metal salt. Such materials may be used in recording instruments of the kind in which a heated stylus replaces an inked pen ; some give a visible image when exposed under a Cooper-Hewitt quartz mercury vapour arc, or images that may be developed as with metal-hydroquinone, or a solution of hydroquinone and acetic acid, while others are photo-thermo-graphic, i.e., they yield a visible image when heated after exposure to light. In an example, paper is first bathed at room temperature in a bath of concentrated sulphuric acid and potassium dichromate to produce surface oxidation, washed, and dried. Paper so treated is already heat-sensitive. The oxidized layer is then converted into a water-insoluble metal salt of cellulose carboxylic acid by bathing in a metallic salt solution, washing and drying, the sensitivity being thereby considerably increased. Metallic salts giving good results are certain salts of silver, mercury, ammonium and iron. Less sensitive materials are produced by certain salts of bismuth, cobalt, copper, lead, manganese, thallium, tellurium and uranium. Salts of metals having an atomic weight greater than 50 are preferred. In modified examples, the paper is first treated in an oxidizing atmosphere as of nitrous fumes; or cellulose fibres are oxidized and coated, e.g. on paper, glass or a cellulose derivative film, as described in Specification 531,283, and in this case the fibres may be treated with the metallic salt solution before coating.
