    摘要： A system includes a computer generated hologram (CGH) design plane and a processor capable of representing a three dimensional object. The processor is configured to represent a surface of the three dimensional object by a facet, impose a grid defining a set of nodes upon the facet, and associate object points with each node of the grid. The processor is further configured to orient the facet to include a common global origin in the CGH design plane and displace the object points away from their associated node in a random or pseudo random direction parallel to the CGH design plane.

    摘要： A thermosetting powder coating composition according to the present invention comprises as binder a co-reactable particulate mixture of a carboxylic acid-functional polyester component and a curing agent having groups reactive with carboxylic acid groups, characterized in that the carboxylic acid-functional component comprises a semi-crystalline polyester having an acid value of from 10 to 70 mg KOH/g and a hydroxy value of no more than 11 mg KOH/g. Generally the semi-crystalline polyester has one or more Tg values less than 55° C., a sharp melting point of 50 to 200° C. and preferably a number average molecular weight of at least 1600. The composition may, if desired, include an amorphous polyester and the curing agent may be, for example, an epoxy resin or a bis(beta-hydroxyalkylamide).

    摘要： The invention provides an improved means for displaying computer generated hologram (CGH). Images appearing in the image volume are realised as a set of planar facets that approximate to the shape of the original object to be displayed. These facets are populated with points, that act as the visible parts of the displayed image. When an object is displayed, certain facets will not be face on the viewing zone. This will result in an apparent surplus of points on these facets, which is wasteful of computing effort. The current invention thus provides for certain facets to be denuded of points if these facets are not presented face on to the viewing zone of the CGH. The invention is mainly applicable for producing CGHs using the interference based algorithm, but can also be used in other types of 3D display that make up objects from an array of points.

    摘要： A cordless electrical appliance comprises an appliance part comprising at least two functional components (T1, M1) and a base for supplying electrical power to the appliance part. A cordless electrical connector (6) makes electrical connection between the appliance part and the base part in use. Both of the functional components (T1, M1) are connected between a pair of electrical connections provided by the connector (6) and arranged such that at least one of the functional components (T1, M1) is selectively energised in response to a change in the relative polarities of the two electrical connections. A switch such as a diode (D1) may be provided between the two functional components (T1, M1), so as to switch ON or OFF the current to a functional component (T1, M1) depending on the polarity of the connections.
