Abstract: When detecting the position and gaze direction of eyes, a photo sensor (1) and light sources (2, 3) placed around a display (1) and a calculation and control unit (6) are used. One of the light sources is placed around the sensor and includes inner and outer elements (3'; 3''). When only the inner elements are illuminated, a strong bright eye effect in a captured image is obtained, this resulting in a simple detection of the pupils and thereby a safe determination of gaze direction. When only the outer elements and the outer light sources (2) are illuminated, a determination of the distance of the eye from the photo sensor is made. After it has been possible to determine the pupils in an image, in the following captured images only those areas around the pupils are evaluated where the images of the eyes are located. Which one of the eyes that is the left eye and the right eye can be determined by following the images of the eyes and evaluating the positions thereof in successively captured images.

During the leaching of the initial glass the leach acid may be cooled to precipitate boric acid. The dopant may be precipitated by thermal and/or chemical treatment, by solvent exchange or by common ion effect. The doped matrix may be treated with solvent to provide an undoped surface layer and the removal of solvent may be at least initially under vacuum.

Abstract: 1527451 Modified phenol-formaldehyde precondensates TH GOLDSCHMIDT AG 11 Jan 1977 [12 Jan 1976] 980/77 Heading C3R [Also in Divisions E1 and B5] A method of modifying a phenol-formaldehyde precondensate comprises incorporating in the precondensate a compound of the general formula generally in an amount of from 3-20% wt., based on the weight of precondensate solids, wherein R is an aliphatic or cycloaliphatic radical having 4-6 carbon atoms or a phenyl radical and x is 1 to 2. Preferably R is butyl isobutyl, cyclohexyl or phenyl. The modifying agent can be added at any stage of the manufacture of the precondensate, e.g. at the beginning of the reaction or to the finished precondensate. The modifying agent is cocondensed into the resin upon curing. In the examples an aqueous solution of an alkaline-condensed phenol-formaldehyde precondensate is modified with (1) a mixture of C 6 H 5 OCH 2 CH 2 OH and C 6 H 5 (OCH 2 CH 2 ) 2 OH; or (2) C 4 H 9 OCH 2 CH 2 OH alone or together with C 4 H 9 (OCH 2 CH 2 ) 2 OH. Uses.-The modified precondensates can be used in the manufacture of shuttering for concrete by impregnating and coating a carrier, e.g. a paper, with an aqueous solution of the modified precondensate and then heat-pressing the coated carrier onto a substrate, e.g. a woodbased material.
