20160037231 | DATA COMMUNICATIONS - Embodiments herein provide systems and methods for sending broadband data to end-users over a DTTV broadcast transmission. Systems and methods for receiving such data are also described. A wireless overlay system is set up by an Internet Service Provider/Communications Provider (ISP/CP) 11 by means of receiving from end-user equipment 27 data requests over a DSL uplink together with identification of at least one DTTV transmitter 21 23. The ISP/CP 11 provides an overlay controller 26 which causes routing of the requested data over a selected DTTV transmitter 21. At the end-user equipment, the requested data can be received from the DTTV broadcast and extracted for output. | 02-04-2016 |

20130258663 | ILLUMINATION APPARATUS - An illumination apparatus comprises a plurality of LEDs aligned to an array of directional optical elements wherein the LEDs are substantially at the input aperture of respective optical elements. An electrode array is formed on the array of optical elements to provide at least a first electrical connection to the array of LED elements. Advantageously such an arrangement provides low cost and high efficiency from the directional LED array. | 10-03-2013 |
20130271959 | ILLUMINATION APPARATUS - An illumination apparatus in which an array of light-emitting elements and an array of light directing optics are provided between first and second attached mothersheet substrates wherein the thickness of at least one mothersheet substrates is most between about 0.01 mm and about 1.1 mm thick so as to minimise LED junction temperature. | 10-17-2013 |
20140016314 | ILLUMINATION APPARATUS - A light emitting element array for an illumination apparatus, an illumination apparatus and method of manufacture of the same in which an array of light-emitting elements and an array of light directing optics are provided between first and second attached mothersheet substrates wherein the thermal resistance of at least one of the mothersheet substrates is reduced by means of thickness reduction so as to provide reduced LED junction temperature. | 01-16-2014 |
20140306612 | ILLUMINATION SYSTEM - An illumination system is provided. The illumination system comprises an array of light emitting elements, an array of directional optical elements and a light deflecting means arranged to provide a fan of light cones. A position detector senses the retroreflection from an observer's eyes and a control system reduces the intensity of light directed towards the retroreflection region. Such a system achieves glare reduction for a line-of-sight illumination apparatus. | 10-16-2014 |
