An eye tracker having a waveguide for propagating illumination light towards an eye and propagating image light reflected from at least one surface of an eye, a light source optically coupled to the waveguide, and a detector optically coupled to the waveguide. Disposed in the waveguide is at least one grating lamina for deflecting the illumination light towards the eye along a first waveguide path and deflecting the image light towards the detector along a second waveguide path.

Apparatus for eye tracking

An Electrically Switchable Bragg Grating (ESBG) despeckler device comprising at least one ESBG element recorded in a hPDLC sandwiched between transparent substrates to which transparent conductive coatings have been applied. At least one of said coatings is patterned to provide a two-dimensional array of independently switchable ESBG pixels. Each ESBG pixel has a first unique speckle state under said first applied voltage and a second unique speckle state under said second applied voltage.

Laser illumination device

There is provided a transparent wearable data display comprising: a source of collimated light; a means for deflecting said collimated light into a scanned beam; a first array comprising one column and integer N TOWS of switchable grating elements sandwiched between first and second parallel transparent substrates, the substrates together functioning as a first light guide; an second array comprising M columns and N rows of switchable grating elements sandwiched between third and fourth, parallel transparent substrates the substrates together functioning as a second light guide; transparent electrodes applied to opposing faces of the first and second and the third and fourth substrates. Hie apparatus further comprises a first coupling means tor directing the scanned beam into a first TIR light path between the outer surfaces of the first lightguide along the first array column; and a second coupling means for directing the first HR light into a second TIR path between the outer surfaces of the second lightguide along a row of elements of the second array.

Wearable data display

An eye tracker having a first waveguide for propagating illumination light along a first waveguide path and propagating image light reflected from at least one surface of an eye along a second waveguide path. At least one grating lamina for deflecting the illumination light out of the first waveguide path towards the eye and deflecting the image light into the second waveguide path towards a detector is disposed adjacent an optical surface of the waveguide.

Holographic waveguide eye tracker

There is provided a contact image sensor comprising: an illumination; a first SBG array device; a transmission grating; a second SBG array device; a waveguiding layer comprising a multiplicity of waveguide cores separated by cladding material; an upper clad layer; and a platen The sensor further comprises: means for coupling light from said illumination means into the first SBG array; means for coupling light out of the cores into output optical paths coupled to a detector comprising at least one photosensitive element.

The present invention relates to nucleic acid fragments encoding amino acid sequences for flavonoid biosynthetic enzymes in plants, and the use thereof for the modification of, for example, flavonoid biosynthesis in plants, and more specifically the modification of the content of condensed tannins. In particularly preferred embodiments, the invention relates to the combinatorial expression of chalcone synthase (CHS) and/or dihydroflavonol 4-reductase (BAN) and/or leucoanthocyanidine reductase (LAR) in plants to modify, for example, flavonoid biosynthesis or more specifically the content of condensed tannins.

Nucleic acids and nucleic acid fragments encoding amino acid sequences for flavonoid biosynthetic enzymes in plants, and the use thereof for the modification of flavonoid biosynthesis in plants.More particularly, the flavonoid biosynthetic enzyme is selected from the group consisting of chalcone isomerase (CHI), chalcone synthase (CHS), chalcone reductase (CHR), dihydroflavonol 4-reductase (DFR), leucoanthocyanidin reductase (LCR), flavonoid 3', 5' hydrolase (F3'5'H), flavanone 3-hydroxylase (F3H), flavonoid 3'-hydroxylase (F3'H), phenylalanine ammonia-olyase (PAL) and vestitone reductase (VR), and functionally active fragments and variants thereof (62) Divided Out of 531985

Manipulation of flavonoid biosynthesis in plants

The present invention relates to nucleic acids or nucleic acid fragments encoding amino acid sequences for proteins MADS-box proteins, CENTRORADIALIS, APETALA2, and Homeo-box proteins from ryegrass (Lolium) or fescue (Festuca) which are involved in the control of plant life cycles and/or growth phases, flowering processes, flowering and/or plant architecture, and/or inflorescence and/or flower development in plants, and the use thereof for the modification of plant life cycles and/or growth phases, flowering processes, flowering and/or plant architecture, and/or plant architecture, and/or inflorescence and/or flower development in plants.

Manipulation of flowering and plant architecture

The present invention relates to polynucleotides encoding cinnamyl alcohol dehydrogenase 3 like (CAD3L) polypeptides. CAD3L polypeptides are produced in a plant in the same organs and the same developmental stages and processes as CAD3 and are likely to be involved in the same developmental processes as CAD enzymes. They can be used for modification of, for example, lignification, cellulose degradation, plant cell walls or plant defence response.

The present invention relates to polynucleotides encoding cinnamyl alcohol dehydrogenase 2 like (CAD2L) polypeptides. CAD2L polypeptides are produced in a plant in the same organs and the same developmental stages and processes as CAD2 and are likely to be involved in the same developmental processes as CAD enzymes. They can be used for modification of, for example, lignification, cellulose degradation, plant cell walls or plant defence response.
