20130318017 | Devices for Learning and/or Decoding Messages, Implementing a Neural Network, Methods of Learning and Decoding and Corresponding Computer Programs - A learning and decoding technique is provided for a neural network. The technique involves using a set of neurons, referred to as beacons, wherein said beacons are binary neurons capable of assuming only two states, an on state and an off state. The beacons are distributed in blocks of a predetermined number of beacons and being allocated for processing a sub-message. Each beacon is associated with a specific occurrence of the sub-message. Learning includes splitting a message into B sub-messages to be learned, where B is greater than or equal to two; activating, for a sub-message, a single beacon in each block to be in the on state, all of the other beacons of the block being in the off state; and activating binary connections between the on beacons of each of the block for a message to be learned, which assume only connected and disconnected states. | 11-28-2013 |
20120057648 | METHOD FOR ENCODING DATA WITH AT LEAST TWO ENCODING STEPS, AND AT LEAST ONE PERMUTATION STEP, CORRESPONDING ENCODING DEVICE, COMPUTER PROGRAM AND SIGNAL - A method is provided for encoding data to be sent to at least one receiver, including at least two identical encoding steps and at least one permutation step. Each encoding step associates a block of encoded data with a block of data to be encoded, using at least two basic codes, each code processing a subset of the data block to be encoded. The permutation step is inserted between two encoding steps, i.e. a current encoding step and a previous encoding step, such that the order of the data in a data block to be encoded by the current encoding step is different from the order of the data encoded by the previous encoding step. The permutation step implements, for a data block, a rotation applied to the data of the data block and a reversal of the order of the data of the data block. The operations can be implemented by an interleaving matrix. | 03-08-2012 |
20120038840 | OPTICAL SHUTTERING DEVICE BASED ON LIQUID CRYSTALS WITH ATTENUATION OF SWITCHING NOISES OF SAID LIQUID CRYSTALS, CORRESPONDING VIEWING GOGGLES AND DISPLAY DEVICE - An optical shuttering device is provided, which includes an optical cell with a liquid crystal material between first and second transparent substrates and controlled by an electronic switching circuit. The switching circuit includes a power supply module, providing a control voltage, and a switching element mounted in series between the power supply module and the cell, making it possible to switch the cell between an on state and an off state. The electronic switching circuit furthermore includes a current source mounted in series between the power supply module and the switching element. The substrates preferably have different thickness and material. | 02-16-2012 |
20110018984 | SPECTACLES FOR THREE-DIMENSIONAL VIEWING OF DIGITAL VIDEO CONTENT FROM A PROJECTOR - Liquid crystal spectacles are provided for three-dimensional viewing of digital video content from a projector. The viewing spectacles include a first rectilinear polariser and a second rectilinear polariser respectively having polarisation axes P | 01-27-2011 |
