| 20090211998 | INTELLIGENT CONTROLLED PASSIVE BRAKING OF A RAIL MOUNTED CABLE SUPPORTED OBJECT - A lift system for lifting and moving heavy parts in an assembly environment. The system includes an overhead cart that travels along a rail. A cable connected to the cart is coupled to the part to lift and move the part. The cart includes a braking device and a controller that controls braking of the cart on the rail. When the cart is moving along the rail, and the worker wishes to stop the part at the assembly location, the worker can initiate the braking operation of the cart by pressing a button. The braking device and the controller control the braking of the cart by applying and releasing the brake in a manner determined by the mass of the cart and the mass of the part so that as the cart is being stopped, the part is prevented from swinging. | 08-27-2009 |
| 20090235846 | Reconfigurable pallet - A pallet includes a platform and a plurality of support assemblies located at multiple positions on the platform. One support assembly is associated with each location of the component to be supported. Each support assembly has several linkage assemblies to position a support element in a desired location for each version of a component.
