Abstract: A retro-reflective sensor coating arrangement comprises a base layer of luminescent sensor material and an outer layer of optical bodies, such a spheres.

Abstract: A temperature indicating paint is provided. The paint is spreadable onto a surface of an article. The paint includes particles of an alloy of two or more metals. The particles vary in relative composition of the metals such that particles having different compositions have different solidus and liquidus melting temperatures.

Abstract: A thermocouple connector has a first member and a second member which couples to the first member. The first member carries two first terminals for electrically joining to the respective ends of a pair of thermocouple wires. The second member carries two corresponding second terminals for electrically joining to the respective ends of a pair of thermocouple extension wires. Each first terminal contacts a respective second terminal when the first and second members are coupled.

Abstract: An apparatus (10) for measuring temperature using luminescence thermometry, comprising: a photon emitter (42) for providing photons (3) of at least a first frequency; photoluminescent material (30) that produces photons (5) of at least a second frequency in response to the incidence of photons (3) of the first frequency; one or more photon receivers (44); and an optically dispersive element (50) for directing photons (5) of at least a second frequency produced by the photoluminescent material (30) into the photon receiver(s).

Abstract: A system (100) and method (200) for general notification of newly-acquired information by: subscribing (230) an indexing service (124; 128) to a broker (140) for a predetermined selection of information stored on an object server (110); and producing related information associated with the information stored on the object server, and publishing (220) the related information to the broker (140) for use in retrieval of the stored information from the object server. The related information preferably comprises metadata and tokens, and the indexing service the metadata for indexing and if the metadata is not relevant to its level of indexing uses the tokens to retrieve a copy of the related information for further analysis. This provides a combination of anonymous publish/subscribe technology to integrate otherwise centralised indexing and object storage, allowing content to be “pushed” to end user clients (130).

Abstract: A method of measuring temperature of a component capable of emitting thermal radiation and reflecting background radiation having the steps of: providing a pyrometer for measuring the radiation from the component, characterised by coating a part of the component with a first emissivity coating and a part of the component with a different and second emissivity coating, each with known emissivities EH and EL respectively, recording a first radiation measurement from the first emissivity coating RH and a second radiation measurement from the second emissivity coating RL, then calculating the true radiation RBlade from the component from the equation R Blade = ( R H E H - R L E H ? ( 1 - E H 1 - E L ) ) ( 1 - E L E H ? ( 1 - E H 1 - E L ) ) and relate the RBlade value to the true component temperature by calibration of the pyrometer.

Abstract: A method of generating metadata is provided including providing (401) a plurality of source texts (100), processing the plurality of source texts (100) to extract primary metadata in the form of a plurality of sets of words (104, 106), and comparing (407) each of the source texts (100) with each of the sets of words (104, 106). The method includes using a clustering program to extract the sets of words (104, 106) from the source texts (100). The step of comparing is carried out by Latent Semantic Analysis to compare the similarity of meaning of each source text (100) with each set of words (104, 106) obtained by the clustering program. The comparison obtains a measure of the extent to which each source text (100) is representative of a set of words (104, 106).

Abstract: An interactive data interpretation tool is disclosed for enabling the identification of the position of features in a multidimensional data set, the tool comprising means for displaying an image representing a 2-D slice of the data set; and user input means for causing the storage of the position of a feature in the displayed image, characterized in that the 2-D slice can be displayed as part of a projection of a 3-D image, the third dimension of which corresponds to one of the other dimensions of the data set, the tool comprising means operable in response to a predetermined user input operation to cause the co-ordinate of the currently displayed 2-D slice in the third dimension of the 3-D image to be incremented, and the positions in the 3-D image of any features identified in the previously displayed slice to be indicated. The invention finds particular application to the interpretation of seismological data sets. Other applications include oceanographic and medical imaging data sets.
