Abstract: A radiation concentrator suitable for use in concentrating solar radiation for efficient and low cost solar photovoltaic use, especially for example in window-mounted devices, has a radiation-transmissive element for receiving incident radiation and includes a radiation-absorbing material for absorbing incident radiation and emitting emissive radiation, a radiation output for transmitting concentrated emissive radiation, the transmissive element acting as a wave-guide for guiding the emissive radiation to the radiation output. The concentrator is characterized by the radiation-absorbing material comprising one or more photoluminescent dyes capable of phosphorescence which exhibit a high quantum yield of phosphorescent emission that is spectrally shifted from the material's absorption.

Abstract: A method and system of capturing a three dimensional image of an object or scene and using the information obtained to produce a physical representation of the object or scene. The physical representation may be dynamic, for moving objects, or permanent.

Abstract: The invention provides an element for a colour electroluminescent display for displaying multicoloured information, each element comprising at least two sub elements. One sub element comprises an electroluminescent material and a fluorescent material and a further sub element comprises the electroluminescent material and a filter material to select a portion of the electroluminescent emission.

Abstract: The present invention provides a method of manufacturing a heating element having a desired pattern of conductive tracks forming a power dissipative conductive track pattern with a desired resistivity and power output, the method comprising providing a photosensitive or pressure-sensitive element comprising: a support having coated on at least one side thereof a photo-sensitive or pressure-sensitive layer, which is capable of, upon imagewise radiation or pressure exposure according to the desired pattern and development of the resulting latent image, providing a metal image according to the desired pattern; imagewise radiative- or pressure-exposing the layer of the element according to a desired conductive pattern to form a latent image in the layer; and developing the element to form a conductive metal pattern, corresponding to the pattern of the latent image, on the support. The heating element may be formed on a flexible support and finds particular utility in heated window/windscreen applications.

Abstract: A patterned electrical conductor having improved conductivity and controllably high resolution track and gap widths is obtained by exposing, to a desired conductive pattern, a pressure-sensitive or photosensitive element comprising a support and a pressure-sensitive or photosensitive material coated thereon being sensitive to the exposure (e.g. the wavelength of exposing radiation) and capable of providing a latent image upon exposure, and then developing the exposed element to form a developed element having a metal (e.g. silver) image thereon and then electroless plating and/or electroplating the metal image with a second metal (e.g. silver) whilst subjecting the developed element to ultrasonic agitation.
