20120242543 | MULTI-CHANNEL RECEPTION SYSTEM - A reception system including a receiver coupled to a processing means, the receiver comprising a number N of antennas, each being able to pick up signals representative of incident waves and to deliver a pulse dependent on said signal, N being an integer. Said receiver includes: N delay lines respectively coupled to each of said N antennas, each delay line being able to delay the signal delivered by the antenna with which it is associated by its own time delay, a coupling means able to sum the N signals delivered by the N delay lines, so as to deliver an output signal comprising a series of N time-shifted pulses. The processing means includes a measurement means able to measure the signal delivered by the coupling means and to deliver as output a signal formed by measurement samples, representative of the N pulses delivered by the N antennas. | 09-27-2012 |
20120281689 | MULTI-CHANNEL RECEPTION SYSTEM INCLUDING A SUPERHETERODYNE-TYPE RECEIVER ASSOCIATED WITH SPECTRAL ANALYSERS WITH INSTANTANEOUS BANDWIDTH - A reception system including a receiver of superheterodyne type coupled to a processing means, the receiver including N antennas. Said receiver includes: N translation means, each being able to frequency translate signals delivered by the antenna considered, from a frequency sub-band of the span of interest to a restricted frequency band, and to frequency multiplex the signals belonging to said frequency sub-band; N first intermediate frequency bandpass filters, of bandwidth equal to said restricted frequency band, respectively coupled at the output of each translation means, and able to filter the translated and multiplexed signals; a coupling means able to sum the N filtered signals so as to deliver the set of summed signals via N outputs. The processing means includes N other translation means coupled to N other intermediate frequency bandpass filters of frequency bandwidth equal to L, themselves coupled to N spectral analyzers, all having the same restricted analysis frequency band of width L, each other translation means of rank i, i being an integer varying from 1 to N, being able to transpose the signals delivered by the coupling means with the aid of a translation signal having a frequency adapted to each other translation means, in such a way that the other intermediate frequency bandpass filter connected at the output of said other translation means, is able to filter the ith sub-band of the total frequency band of width L·N, to which the signals summed by the coupling means belong. | 11-08-2012 |

20130121368 | DEVICE EVALUATING THERMOMECHANICAL FATIGUE OF A MATERIAL - A system for cooling and holding a testpiece in an effective manner while the testpiece is subjected locally to high heat flux. The testpiece includes an inside face extended by parallel strips that leave between them channels for passing a cooling fluid, and parallel fins of an intermediate part are inserted between the strips. | 05-16-2013 |
20140245833 | APPARATUS AND METHOD FOR CARRYING OUT IN A CONTROLLED ATMOSPHERE MATERIAL FATIGUE TESTS IN A HIGH CYCLE REGIME WITH A CONTROLLED STRAIN RATIO - An apparatus for carrying out high cycle fatigue tests of a specimen under high pressure, including: a pressure vessel; a load train including a first horn and a second horn between which a specimen is to be arranged, wherein the load train is arranged within an internal chamber of the pressure vessel; and a converter configured to apply ultrasonic waves into the load train by exciting the first horn to apply a dynamic stress to the specimen. A base part of the second horn is movably seated in the pressure vessel such that two separated chambers are formed within the pressure vessel with the first chamber for the specimen, wherein both chambers can be fed with gas and charged with different gas pressures in order to apply a static stress to the specimen. | 09-04-2014 |

20130024152 | METHOD FOR CALIBRATING WIM-SENSORS - A method for calibrating a WIM (Weigh in Motion) sensor built into a road during travel of a calibrating vehicle measures the dynamic wheel force on the road and on the WIM sensor directly at the measuring wheel, depending on time or location. These wheel force data are transmitted to an evaluating unit. As the calibrating vehicle passes over, WIM signal data are simultaneously measured at the WIM sensor and transmitted to the evaluating unit. The wheel force data are synchronised with the WIM signal data in the evaluating unit. A calibration function is determined by comparing the dynamic wheel force data with the WIM signal data. | 01-24-2013 |
20140251700 | HOLLOW PROFILE SENSOR - A hollow profile sensor for installation in roads or a road surface for the purpose of sensing the weight of vehicles and/or driving dynamics reactions of vehicles or vehicle wheels to the road includes a tube part having a hollow interior profile. A counterpart is connected to the tube part. A measuring arrangement is held in the hollow interior profile between the tube part and the counterpart. A force introduction flange is connected to the tube part in such a manner that force application lines are concentrated on the measuring arrangement. | 09-11-2014 |

20150042304 | ELECTRONIC CIRCUIT FOR A WEIGHT-IN-MOTION SENSOR - An electronic circuit that changes a charge signal into a voltage signal within a sensor suitable for direct installation in a roadway can be connected to two single-core cables that need not be highly insulating yet can realize the required power supply of the electronics. The circuit includes an integrated impedance converter (IEPE) at the output to a two-core cable and a charge amplifier with an IC | 02-12-2015 |
20150075297 | HOLLOW PROFILE FOR A WEIGHT-IN-MOTION SENSOR - A WIM (weigh-in-motion) sensor has an oblong hollow profile and includes two force-transmission plates arranged parallel to each other. A tube is arranged between the plates and is integrally formed with the plates and defines a hollow space. Two supports that are arranged opposite one another are formed inside the hollow space, each support extending away from a respective plate and between which a measuring element is received centrally in the tube under preload. The tube includes two tube segments designed to be mirror-symmetrical with respect to each other, which join the plates together and on the inside adjoin the hollow space. The wall thickness of each tube segment has a relatively thick region between at least two relatively thin regions. | 03-19-2015 |

20150122928 | FOOD MINCER - A food mincer providing improved features. The suction base includes a control ring providing an improved visual indication of its position. The plunger to feed the food is formed as a hollow container having a sealing lid to provide a storage area for accessories. The feed screw is formed in a multi-step molding process to allow for closer tolerances, which in turn allows for a simple gasket seal to be used. The feed screw and fan blade include a mating configuration only when the fan blade is in the proper orientation, such that if the fan blade is assembled in the incorrect orientation the extrusion grids may not be assembled. | 05-07-2015 |
