Abstract: A method of fabricating a structure comprising the steps of: providing an electrical conductor; providing a layer of a flexible insulating material on the electrical conductor, the material comprising: a first organo-alkoxide 1RxSi(O1R?)4-x and a second organo-alkoxide 2RxSi(O2R?)4-x, where 1R is a non-hydrolysable organic moiety thermally stable to a temperature of at least 150° C., 2R is a non-hydrolysable organic moiety containing a functional group that can react with another like functional group to form an organic polymer, 1R? and 2R? are alkyl radicals and x is an integer from 0 to 3; and an inorganic filler material.

Abstract: Computer input apparatus comprising: an image capture device; and a marker member comprising at least two reference indicia, at least a first reference indicium being arranged to emit or reflect light having a first spectral characteristic, and at least a second reference indicium being arranged to emit or reflect light having a second spectral characteristic different from the first spectral characteristic, the image capture device being arranged to distinguish light of said first spectral characteristic from light of said second spectral characteristic thereby to distinguish the at least a first reference indicium from the at least a second reference indicium, the apparatus being configured to capture an image of the at least two reference indicia and to determine by means of said image a position and orientation of the marker member with respect to a reference frame.

Abstract: A device primarily for indicating when a seat belt is disconnected comprises an electronic unit housed in or on the buckle of the seat belt, and including a switch the condition of which is altered on insertion and removal of the seat belt key into and from the buckle. On insertion of the key into the buckle a first signal indicative of connection of the seat belt is transmitted from the device and, on removal of the key from the buckle, a second signal indicative of disconnection of the seat belt is transmitted from the device.
