A patent describing a computer architecture which implements a Perspex instruction.

Processors (WO 2010/082067 A2)

A processing system comprises a plurality of processors (12) and communication means (20) arranged to carry messages between the processors, wherein each of the processors (12) has an operating instruction memory field (32, 34, 36) arranged to hold stored operating instructions including a re-routing target address. Each processor is arranged to receive a message (38) including operating instructions including a target address. On receipt of the message, each processor is arranged to: check the target address in the message to determine whether it corresponds to an address associated with the processor; if the target address in the message does correspond to an address associated with the processor, to check the operating instructions in the message to determine whether the message is to be re-routed; and, if the message is to be re-routed, to replace operating instructions within the message with the stored operating instructions, and place the message on the communication means for delivery to the re-routing target address.

Improvements in or relating to the manufacture of multilayer interference filters

This invention relates to the manufacture of multi-layer interference filters for use with infra-red radiation, especially at wavelengths beyond 3.8 microns. A method of manufacturing a multi-layer interference filter comprising the steps of forming on a substrate successive layers of lead telluride and another material in alternation, under conditions in which sufficient oxygen is included in the lead telluride layers to reduce the apparent free charge carrier concentration therein, so that the resulting filter exhibits enhanced transparency to radiation of wavelengths greater than 3.8 microns and enhanced natural absorption to radiation of wavelength less than 3.8 microns.

Improvements relating to the manufacture of coated substrates

This invention relates to the manufacture of coated substrates, and particularly, but not exclusively, to the deposition of multi-layer coatings in the manufacture of interference filters consisting of multiple thin films. An object of the invention is to allow accurate control of the deposition of a succession of layers having good uniformity, for example during the manufacture by vacuum evaporation of multilayer interference filters for use with infrared radiation of particularly long wavelength, using a method which is self calibrating and which avoids the repetitive use of individual control layers.

A análise da relação trabalho e saúde na atividade dos bombeiros militares do Rio de Janeiro

Este estudo teve como objetivo analisar a dinâmica trabalho e saúde na atividade dosbombeiros militares de uma Corporação na cidade do Rio de Janeiro. Como foco deinvestigação privilegiamos as narrativas relativas ao cotidiano dos trabalhadores, levandoem consideração o cenário encontrado na ocasião da pesquisa. Para marco teóricoconceitualforam selecionados os aportes da psicodinâmica do trabalho, da ergologia, daclínica da atividade e da psicossociologia. A perspectiva metodológica foi situada noâmbito da pesquisa qualitativa de natureza exploratória. Utilizamos a abordagem dashistórias de vida, guiada por um roteiro, juntamente com a aplicação de um pequenoquestionário, o qual registrou alguns dados mais objetivos. Os sujeitos da pesquisacompuseram um grupo de 20 (vinte) bombeiros de diversas patentes militares. A análisedos resultados foi organizada em três grandes seções com os seus respectivosdesdobramentos 1) Contextualização do cenário de atividade; 2) Narrativasprofissionais de três bombeiros militares e por último 3) A realidade de ser bombeiro.A aproximação do cenário, vivido pelos bombeiros militares, permitiu o exame dassituações que foram vivenciadas em um momento de tensão no campo das negociaçõespor direito à saúde e ao trabalho. Em função desta pauta, analisamos os depoimentos dostrabalhadores à luz do marco teórico conceitual proposto e neste mesmo percurso foipossível fazer emergir os aspectos que, em decorrência da natureza da atividade, exercemimpactos na saúde dos profissionais. Por tratar de uma atividade cujo principal objetivo ésalvar vidas e bens, os profissionais trabalham sob um clima de tensão e risco à própriavida. Contudo, concluímos diante dos resultados do estudo que, embora os bombeirosmilitares estabeleçam correlações entre o trabalho e a saúde, a categoria ainda não possuidispositivos coletivos para minimizar os efeitos deletérios da prática de trabalhoconstituídos desta relação.

Patents for plants: context and current status

One of the important themes in any discussion concerning the application of genetic transformation technology in horticulture or elsewhere is the role of Intellectual Property Rights (IPR). This term covers both the content of patents and the confidential expertise, usually related to methodology and referred to as “Trade Secrets”. This review will explain the concepts behind patent protection, and will discuss the wide-ranging scope of existing patents that cover novel genotypes of plants as well as all aspects of transgenic technology, from selectable markers and novel promoters to methods of gene introduction. Although few of these patents have any significant commercial value there are a small number of key patents that may restrict the “freedom to operate” of any company seeking to exploit the methods in the production of transgenic varieties. Over the last twenty years, these restrictions have forced extensive cross-licensing between ag-biotech companies and have been one of the driving forces behind the consolidation of these companies. Although such issues may have limited relevance in the horticultural sector, and are often considered to be of little interest to the academic scientist working in the public sector, they are of great importance in any debate about the role of “public-good breeding” and of the relationship between the public and private sectors.

Synchronization of digital data decoders

Burst timing synchronisation is maintained in a digital data decoder during multiple burst reception in a TDMA system. The data within a multiple burst are streamed into memory storage and data corresponding to a first burst in the series of bursts are selected on the basis of a current timing estimate derived from a synchronisation burst. Selections of data corresponding to other bursts in the series of bursts are modified in accordance with updated timing estimates derived from previously processed bursts.

Background-noise reduction

Interference by siren background-noise with speech transmitted from radio equipment (3) of an emergency-service vehicle, is reduced by apparatus (1) that subtracts (43) an estimate nk of the correlated siren-noise component from the contaminated signal yk supplied by the cab-microphone (2). The estimate nk is computed by FIR (finite impulse response) filtering of a siren-reference signal xk supplied by a unit (4) from one or more microphones located on or near the siren, or from the electric waveform driving the siren. The filter-coefficients wk are adjusted according to an LMS (least mean square) adaptive algorithm that is applied to the correlated-noise component ek of the fed-back noise-reduced signal, so as to bring about iterative cancellation with close frequency-tracking, of the siren noise.

Between writing and type: the stencil letter

An exhibition of stencil letters from the 18th century to the present day. Co-curated by Eric Kindel and Fred Smeijers, the exhibition featured a wide selection of stencil letters in the context of historical artefacts, documents and ephemera, including stencil plates and stencilling devices, specimens and catalogues and patent inventions. The exhibition also introduced a series of new stencil fonts designed by Maurice Göldner, Pierre Pané-Farré and Fred Smeijers. The design of each font made reference to and was informed by the historical material.

Formulations of viable cells for oral delivery

This invention relates to solid formulations for the oral delivery of live microbial cells which comprise dried viable cells and small amounts of a bile acid binding agent, for example, an anion exchange resin such as cholestyramine. The presence of bile acid binding agents in the formulation significantly increases the survival of the cells in the intestinal tract and facilitates delivery of the viable cells to the intestine.

Immunoassays, methods for carrying out immunoassays, immunoassay kits and method for manufacturing immunoassay kits

The invention relates to immunoassays, methods for carrying out immunoassays, immunoassay kits and methods for manufacturing immunoassay kits. In particular, the invention has relevance to capillary (especially microcapillary) immunoassay technology.
