20150039959 | METHOD FOR DECODING A CORRECTING CODE WITH MESSAGE PASSING, IN PARTICULAR FOR DECODING LDPC CODES OR TURBO CODES - A method for iteratively decoding a word of a correcting code by an iterative decoding algorithm in the course of which, for each bit of said code word, at least one extrinsic information item is generated at each iteration, includes the following steps: an initial step of decoding by means of said iterative decoding algorithm; simultaneously, for each bit of said code word, a step of developing a criterion representing the number of oscillations of at least one extrinsic information item or of one extrinsic information item with regard to another extrinsic information item; if the decoding does not converge; a step of modifying the value of the bit of said code word for which said number of oscillations is highest; and, an additional step of decoding said at least one modified code word by means of said iterative decoding algorithm. | 02-05-2015 |

20140064097 | METHOD FOR OPTIMIZING THE RESOURCES OF A DATA TRANSMISSION AT THE LEVEL OF THE MAC LAYER AND DEVICE IMPLEMENTING THE METHOD - A method for optimizing the resources of a data transmission, based on a set of pairs of modulation and first correcting code, includes: determining, for each pair, maximum rate of a second correcting code applied to data transmitted before application of the first correcting code and of modulation wherein the error rate in data received is maximum a target error rate; the second correcting code applied at the medium access layer, to generate packets of redundancy bits based on packets of data bits received supplemented with padding sections, all having the same size; evaluating an item of information representative of the ratio between bits at input of the medium access layer and bits actually transmitted or of transmission bitrate required for solutions associating modulation, first and second correcting codes; selecting, from among solutions associating modulation, first and second correcting codes, to maximize the ratio or to minimize the transmission bitrate. | 03-06-2014 |
20140351667 | METHOD OF DECODING A CORRECTING CODE, FOR EXAMPLE A TURBO-CODE, BY ANALYSIS OF THE EXTENDED SPECTRUM OF THE WORDS OF THE CODE - An improved decoding method is provided making it possible to solve the problem of the error floor of a turbo-code or of an LDPC code, or more generally of a correcting code from the family of “turbo-like codes”, while preserving the same spectral efficiency, without any decrease in the useful throughput of the encoded stream. This result is obtained by an identification, on input to the decoder, of the bits on which an error has a strong impact, and a modification of the likelihoods corresponding to these bits so as to improve the convergence of the decoder. | 11-27-2014 |

20080222871 | SCRUBBER - A method for assembling tool having a housing into which a motor assembly and a battery assembly are inserted. A circuit board can be employed to electrically connecting the battery assembly to the motor assembly even if the battery assembly and the motor assembly are not disposed in an in-line configuration. The circuit board can include a switch that can be employed to selectively operate the tool. | 09-18-2008 |

20090077814 | Cutting Angle Indicator in Jigsaw Housing with Dust Extraction - A jigsaw generally includes a housing containing a motor activated by a trigger assembly. The housing defines a window. A shoe member pivotally connects to the housing. An indicator wheel is disposed in the housing so that a portion of the indicator wheel is visible through the window, wherein pivoting of the shoe member relative to the housing causes the indicator wheel to rotate. | 03-26-2009 |
20090077818 | Housing of a cutting tool including blade storage, integral blade guard and motor ventilation pathway - A jigsaw that uses a cutting blade generally includes a housing containing a motor activated by a trigger assembly. A blade storage compartment is recessed in the housing. A platform is provided in the blade storage compartment having a first edge that at least partially defines a first recess that extends further into the housing beyond the platform. A member is connected to the platform that produces a magnetic field that releasably secures the cutting blade to the platform. The magnetic field is configured to permit a user to tilt the cutting blade about the first edge of the platform into the first recess to overcome the magnetic field and remove the cutting blade from the storage compartment. | 03-26-2009 |
20090077820 | Control of Reciprocation Speed and Orbital Magnitude of a Jigsaw with a Plurality of Material and/or Task Descriptive Icons - A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion. | 03-26-2009 |

20080295819 | TILE SAW WITH LASER GUIDE - A tile cutting machine includes a tub for receiving water and a tile to be cut therein. A cutting head assembly having a motor driven blade is positioned above a tile supporting surface located in the tub and is movable with respect thereto. A laser projects a line of light from the cutting head assembly down onto the tile supporting surface to provide a visual representation of a cutting path of the blade. A scale permits measurement of a tile to be cut. The laser may be used with the scale to allow a user to quickly determine cutting widths without the need to manually mark the object to be cut. A light source, such as an LED, may be incorporated in the cutting head to illuminate an interior of the tub during operation of the tile cutting machine. | 12-04-2008 |
20110277740 | TILE SAW WITH A TILE HOLD DOWN DEVICE - A tile cutting machine includes a tub for receiving water and a tile supporting surface for supporting thereon a tile to be cut. A cutting head assembly is positioned above the tile supporting surface and includes a motor driven blade. A tile hold down mechanism extends downwardly from the cutting head assembly to engage the tile and apply downward pressure thereto to hold the tile in place during the cutting process. The tile hold down mechanism may take the form of flexible hold down feet, downwardly biased rollers and/or bristle skirts. The tile supporting surface may be fabricated of a high friction material and include a plurality of nubs to cooperate with the hold down mechanism to hold the tile stationary with respect to the supporting surface during the cutting process. The tile cutting machine provides for a method of cutting tile where a user does not have to hold the tile with their hands during the cutting operation. | 11-17-2011 |
