20110259128 | Integrity Evaluation of Prestressed Concrete Girders - A novel and practical methodology that accounts for the specific mechanical features of a prestressed concrete girder (elastic stiffness, cracking moment, fully cracked inertia, and ultimate capacity) and allows the objective delimitation of its damage levels is presented. Results from this procedure show excellent correlation when compared to the experimentally defined damage thresholds. Also, the global integrity parameter is proposed as a new criterion for damage diagnosis and performance evaluation of prestressed concrete girders within the intermediate and heavy damage zones, showing excellent correlation with the experimental information obtained during testing. | 10-27-2011 |

20110232696 | COMPACT RADIATOR-BASED HEAT EXCHANGER - The present invention generally relates to a compact heat exchanger for use in a mobile cleaning apparatus. The compact heat exchanger utilizes a water jacket, created by the annular space between a concentrically arranged internal housing and external housing. A radiator is enclosed within the internal housing. As super heated exhaust gas is supplied to the internal housing, heat is transferred to the surface of the internal housing before passing through the radiator. During operation of the mobile cleaning apparatus, incoming fluid, typically water, flows through an inlet and is directed through the water jacket and then the radiator for heating. | 09-29-2011 |
20110237373 | AUTOMATIC BELT TENSIONING SYSTEM - A device and method of use of that device to automatically adjust the tension of a belt(s) used in a driven system is disclosed. The system includes at least one driving device or power source and at least one driven device. The system further includes a tensioning member that serves to continuously compensate for slack which naturally develops in the belt or belts during normal operation of the system, as well as preloading the device with the appropriate amount of tension. The device provides a manually operated adjustment which allows for user control of the tensioning member, as well as an indicator which displays the amount of elongation of a belt and/or the desired preloaded tension of the system, thus simplifying removal, application, and replacement of belts, etc. | 09-29-2011 |
20110253179 | TOWED PORTABLE CLEANING STATION - A device and method of use for a towed portable cleaning facility is disclosed. The device employs storage tanks for both the storage and transport of cleaning fluids. The tanks serve the additional function of surrounding and enclosing the cleaning area an area that may be used for cleaning or storage. By utilizing the tanks as walls, the present invention provides a portable cleaning station. The device may further include the ability to treat and clean used fluids in order to either reuse or safely dispose of the used fluids as well as the ability to recover heat energy from an engine compartment to heat cleaning fluids. | 10-20-2011 |

20090238228 | Quantum dot based semiconductor waveguide devices - Methods and devices for providing a multiwavelength laser which may be used for multicasting and other optical communications uses. The present invention provides a quantum dot based multiwavelength laser with a monolithic gain block. The Fabry-Perot gain block has both upper and lower InP cladding layers. The laser system has a middle quantum dot layer with multiple stacked layers of InAs quantum dots embedded in InGaAsP. When provided with a CW injection current, the laser system produces an output spectra with equally spaced multiple emission peaks. With an input optical data signal applied to the laser system, the laser system duplicates the data in the input signal across multiple different wavelengths. | 09-24-2009 |
20100142566 | Multi-band multiwavelength quantum dot mode-locked lasers - A multi-band (multi-colour) multiwavelength mode locked laser diode is provided by dynamic phase compensation of a quantum dot active medium. The laser diode is provided with a PIN diode structure where the active medium consists of a plurality of layers of quantum dots such as those produced by self-assembly from known chemical beam epitaxy methods. The multiplicity of bands may be produced by AC Stark splitting, frequency selective attenuation, or by the inclusion of multiple different layers having different, respective, peak ASE emissions. Dispersion compensation within laser facets, waveguides, and the optically active media permit the selection of a fixed dispersion within the cavity. A dynamic group phase change induced by the AC Stark effect permits compensation of the fixed dispersion sufficiently to produce an intraband mode-locked laser. Even interband mode locking was observed. | 06-10-2010 |
