| 20080314498 | Apparatus and Method for Ultrasonic Processing of Laminates - A method for ultrasonic debulking a composite laminate ( | 12-25-2008 |
| 20110114247 | Apparatus and Method for Ultrasonic Processing of Laminates - A method for ultrasonic debulking a composite laminate includes the steps of defining a path across the laminate, the path having a starting location and an ending location and applying a force to and transmitting ultrasonic vibration into the laminate along the path, beginning at the starting location and ending at the ending location. The method further includes determining a temperature of a surface of the laminate proximate to the path and varying at least one of an amplitude of the ultrasonic vibration, the applied force, a feed rate at which the force and the ultrasonic vibration are applied along the path, an angle at which the ultrasonic vibration is applied to the laminate, and an interval at which plies of the laminate are processed, based upon the determined temperature of the surface of the laminate. | 05-19-2011 |

| 20100176184 | ULTRASONIC WELDING USING AMPLITUDE PROFILING - A method of ultrasonic welding aluminum parts together includes placing the aluminum parts in an ultrasonic welding apparatus and contacting at least one of the aluminum parts with a horn tip of a weld horn of the ultrasonic welding apparatus. A weld amplitude is profiled during a weld cycle of the ultrasonic welding apparatus by producing a high weld amplitude above 55 μm at the horn tip of the weld horn during an initial period of a weld cycle and producing a low weld amplitude below 55 μm at the horn tip after the initial period. | 07-15-2010 |

| 20090222129 | Mothod and system for order fulfullment in a distribution center - Order allocation techniques that reduce the number of stops that a container makes in the process of fulfilling a customer order is disclosed. In one embodiment, this is accomplished by first identifying a pod that stocks the largest number of different items in a customer order. Then, a second pod is identified that stocks the largest number of remaining items in the customer order. Ultimately, all items in the customer order are assigned a pod. The collection of pods defines a container path through the distribution center. | 09-03-2009 |
