20130320903 | METHOD AND CONTROLLER FOR AN ELECTRIC MOTOR WITH SWITCH TESTING - For each phase of a controller, a pair of semiconductor switches comprises a high side switch and a low side switch. A direct current voltage bus provides electrical energy to the semiconductor switches at a test voltage level less than a full operational voltage level. A measuring circuit is adapted to measure the direct current bus voltage. A data processor determines that a deficiency in a tested, related semiconductor switch is present if the measured direct current bus voltage decreases or collapses upon activation of a particular semiconductor switch in the same phase of the controller, or if other sequential test results indicate a deficiency. If the deficiency in the related semiconductor switch is present the processor may prevent the voltage supply from providing the full operational voltage to the direct current data bus to prevent damage to the motor or the controller, for example. | 12-05-2013 |

20130143525 | Point of Use Verified Aircraft Assembly Time Collection - A system, method, and apparatus for point of use verified aircraft assembly time collection are disclosed herein. The disclosed method for manufacturing process control involves assigning a plurality of manufacturing tasks to an interactive voice response (IVR) menu associated with a manufacturing process control application. The method further involves selecting one of the plurality of manufacturing tasks assigned to the interactive voice response menu via a mobile telephone device of the user. In addition, the method involves receiving a confirmation response on the mobile telephone device from the manufacturing process control application indicating the manufacturing task selected. In one or more embodiments, the assigning of the plurality of manufacturing tasks involves assigning each manufacturing task to a number. In some embodiments, the number corresponds to a key on the keypad of the mobile telephone device. | 06-06-2013 |

20140166516 | TOOL STORAGE DEVICES - A tool storage device and a tool box. The device may include flexible walls cooperating to define a storage area, and a rigid frame supported in the storage area and including a central portion extending in a direction from a bottom wall toward a top wall, one base portion extending from one side of the central portion, along the bottom wall and toward one side wall, and another base portion extending from an opposite side of the central portion, along the bottom wall and toward an opposite side wall. The tool box may include a body defining a storage compartment; a lid defining a groove in its outer surface to support an elongated work piece; and a handle engageable with a work piece supported in the groove. The lid may be attachable to the top of the body in a closed position and to the bottom in a stowed position. | 06-19-2014 |
