20090167057 | Tractor Cab Suspension System - A tractor cab suspension system includes a plurality of suspension members arranged for supporting the cab on the frame in which some of the suspension members at one end of the cab comprise resilient members compressed between the cab and the frame of the tractor and other ones of the suspension members at the other end of the cab comprise air cushion members. A rollover protection member is associated with each air cushion member to resist separation of the cab from the frame at the cushion member during a rollover of the tractor. The rollover protection members are arranged to couple the cab and the frame for linear sliding movement relative to one another. | 07-02-2009 |

20150107320 | METHOD AND SYSTEM FOR CONTROLLING THE QUALITY OF A STAMPED PART - A system and method for detecting a defective part and the type of defect formed during stamping operations. The system and method will not only detect the defect but also the nature of the defect and the time at which the defect occurred during stamping operations. Such information is useful not only in quality control but also in isolating a problem which may exist in stamping operations and thus eliminating time for isolating such problems and correcting them. The system and method uses a profile of a properly stamped part to detect a defect, and the root cause of the defect. | 04-23-2015 |

20100118137 | GRADIENT IMAGE PROCESSING - A method of assessing the quality of metal parts, for example through detection of defects in a metal part induced by processing the metal part, comprises acquiring a thermal image of the metal part after processing the metal part, determining a difference image by comparing the thermal image to a reference image, the difference image being related to temperature differences between temperature data represented by the thermal image and by the reference image, and determining a gradient image using the difference image, the gradient image representing temperature difference gradients within the difference image. An example apparatus comprises a camera, such as a thermal camera, an image processor, and an output device such as a display. | 05-13-2010 |

20140048111 | METHOD AND SYSTEM FOR PRODUCING AN ELECTRIC CURRENT FROM A TEMPERATURE DIFFERENTIAL - This invention relates to a method and system for producing electrical current based on a temperature differential. The system comprises of at least one unit having a plurality of chips sandwiched between a higher temperature layer on one side and a lower temperature layer on an opposite side. Chips are preferably thermoelectric solid state chips that produce an electric current when there is a temperature differential created across the chips. There are a plurality of chips in each unit and the chips within each unit are electrically connected to one another in series. Preferably, there are a plurality of units. | 02-20-2014 |
