| 20090292966 | Method for recovery of lost and/or corrupted data - A method for recovery of lost and/or corrupted data transmitted from a transmitter device to a receiver device. The data is coded by an encoder connected to the transmitter device. The data is transmitted from the transmitter device to the receiver device via a transmission system and is decoded by means of a decoder connected to the receiver device. This is performed through application of a low density parity check method, wherein lost and/or corrupted data is restored during decoding. The decoding is performed by solving the equation system of the parity check matrix H. The parity check matrix H is brought into a triangular form by column and/or row permutations. Columns of a sub-matrix B of the matrix H which impede the triangulation process are shifted into a sub-matrix P of the matrix H so that the triangulation process can be continued until the matrix H except for the sub-matrix P has been completely brought into a triangular form. The Gaussian elimination method is applied to a part of the sub-matrix P. The selection of the column or columns of the sub-matrix B which are to be shifted into the sub-matrix P is performed on the basis of the weight of the column which corresponds to the number of non-zero-entries in the column, and/or on the basis of the weight of the rows of the sub-matrix B connected to the column. | 11-26-2009 |

| 20110047445 | METHOD FOR RECOVERY OF LOST AND/OR CORRUPTED DATA - A method for recovery of lost and/or corrupted data, whereby this data is encoded by means of an encoder connected to the transmitter device and transmitted via a transmission channel to the receiver device. The transmitted data is decoded by means of a decoder connected to the receiver device wherein lost and/or corrupted data is restored during decoding. Encoding and decoding are performed by using a convolutional code. According to the disclosure the window size, on which the decoder connected to the receiver device operates, is variable so that the window size can be adapted to the erasure rate of the transmission channel and/or to the delay service requirement. | 02-24-2011 |
| 20110096795 | METHOD FOR CONTENTION RESOLUTION IN TIME-HOPPING OR FREQUENCY-HOPPING - The invention is related to a method of transmitting data, whereby a transmission channel towards an access point is shared among a plurality of users. The data is transmitted by using a multiple access frame divided in logical slots. According to the invention each data packet is divided into k units which are decoded by an (n,k) decoder, producing n−k redundant units. The n units are transmitted within a multiple access frame in n different slots according to a time-hopping pattern, a frequency-hopping pattern or a combination of both. Thereby, the positions of the n units composing a data packet are written in a header appended to each unit. | 04-28-2011 |

| 20100108113 | Aeroelastic canopy with solar panels - An aeroelastic solar-power-generating canopy is described that requires minimal construction efforts. The canopy can be formed over supporting structures such as columns, without requiring an existing roof. The canopy contains a plurality of solar panels arranged substantially adjacent to each other, which are coupled to attachment members. Linking members are coupled to the attachment members, the linking members providing a flexing point for the solar panels. A cable is coupled to the linking members, spanning a substantial portion of the distance covered by the solar panels, providing a restraining force. And, at least one of the attachment members and cable is coupled to a supporting structure, wherein the cable in conjunction with the linking members allows the solar panels to dynamically react to loads, the arranged solar panels operating as a covering and as a source of solar power. | 05-06-2010 |
| 20100175337 | Flexible roof-mount system and method for solar panels - Systems and methods are disclosed for efficiently securing solar panels on a roof surface that does not require penetration of the roof membrane. Supports for the solar panels are designed with a small footprint with sufficient spacing to allow free drainage between the supports. A simple, low-cost attachment member or clip can be integrated with each support to attach the panel to the support, and in some instances the clip (or its mount on the support) can also be used to lift the support to the roof. The panels can include one or more rails that can slide through a loosened clip, but be held securely in place by a tightened clip. The panels can be installed initially with the clips grasping the rails loosely and once the supports and rails are in their final positions, the clips can be fully tightened to form a rigid solar panel array. | 07-15-2010 |
