Universitat Politècnica de Catalunya - UPC posted this:Reconfigurable beam reflectarray antenna for frequencies in the range of terahertz and millimeter waveThe reflectarray antenna consists of a flat array of phase-shifter cells (reflectarray) illuminated by a feeder, which produces an electronically reconfigurable collimated or shaped beam, where the cells (3b) consist of several stacked layers of conductive elements (4c, 4e, 4d, 4f) on a dielectric substrate (7c, 7d) alternated with layers of liquid crystal (5c, 5d) and a conductive plane (9). Applying bias voltages in the conducting elements, the dielectric constant of the liquid crystal varies producing a phase shift of the reflected field in each cell, allowing for a electronic beam scanning or reconfiguration. Including multiple layers of conductive elements and liquid crystal, improves the bandwidth and the performance of the beam scanning or reconfiguration. The antenna can be applied to observation satellites, communications and security systems.

Universidad de Alcalá-OTRI posted this:Systems and applications based on indoor positioning via led-lightingThe use of LED lamps available for lighting of different parts of a building or room in such a way as to allow the transmission of very high-frequency codes non-perceptible by humans together with the illumination lights. These codes (one unique code for each LED lamp) will be decoded by light detectors included in smart-devices, or by detectors designed particularly for this purpose. From the code information, the device positioning can be determined with high precision.

RAMOT at Tel Aviv University Ltd. posted this:Delayed Dictionary CompressionData compression is a preferred solution, since there is no need to dig in the ground for many kilometers in order to build new high bandwidth links. The Delayed Dictionary Compression (DDC) family of algorithms was invented by Prof. Yossi Matias and Mr. Raanan Refua. The motivation was to release the bottleneck of low level infrastructures - data transfer links. Current data compression techniques for packet networks allow a good compression and a poor latency, or poor compression ratio and a good latency. Project ID : 4-2012-319
