20090178453 | BENDING APPARATUS AND METHOD OF BENDING A METAL OBJECT - A method of bending a metal object, such as a tube, is provided that uses real time, closed-loop feedback of the actual springback of the object in order to modify the applied bending force or preprogrammed bending coordinates so that the final desired bend geometry is achieved. The variability of springback from object to object is thus accounted for and the number of objects that must be scrapped due to incorrect bends (over bend or under bend) is reduced. The method is carried out using an apparatus such as a rotary draw bender with a measuring device operable to measure actual bend coordinates of metal objects bent by the bender. A controller is operatively connected to the bender and the measuring device and is configured to control the bender to bend the metal objects at least partly based on measured bend coordinates provided by the measuring device. | 07-16-2009 |
20100037670 | Gravity Fill System with Pressure Check Valve - A hydroform die includes a plurality of seal units to provide fluid to die cavities. The plurality of seal units each define a piston cylinder. A piston is located within the cylinder and is selectively moveable between an open and a closed position. Additionally, the piston at least partially defines a valve chamber located on a first side of the piston and a piston chamber located on a second side of the piston. A piston fluid passage is defined by the piston to fluidly connect the valve chamber and the piston chamber. | 02-18-2010 |
20100040485 | High Pressure Dual-Action Hydraulic Pump - A high pressure pump includes a pump housing. A piston rod located within the pump housing defines a plurality of pump cavities and a plurality of piston cavities. Movement of the piston within the piston cylinder pumps the fluid from the piston cavities out of the high pressure pump. The continuous pumping of HWBF from the pump housing provides fluid at a relatively constant flow and pressure. The HWBF pressure is also at a higher pressure than traditional single stage high pressure pumps can provide. | 02-18-2010 |

20130216971 | WIRELESS INTRA-ORAL IMAGING SYSTEM AND METHOD - An intra-oral imaging system includes a handheld intra-oral camera in wireless communication with a remote computing device. The computing device includes a display unit and is linked to databases containing historical data for the teeth of a subject. A dentist actuates a touch-sensitive button to prompt capture of images of the subject's teeth, which are wirelessly transmitted to the computing device and graphically displayed. The images generally represent an arrangement and conditions for the teeth. Program modules are executable to identify a current condition of one or more teeth, and to select a prerecorded visual demonstration of a dental procedure from a database based on the identified current condition. Alternatively, the program modules may extrapolate using the current and historical data to predict a future condition and recommend procedures or otherwise alert the subject to potential future procedures. Visual demonstration of the procedures is provided on the display unit. | 08-22-2013 |

20100096063 | Inspectability of composite items - To improve imaging characteristics of a composite item fabricated from a layup of composite material, layers of sheet molding materials are interleaved with layers of organized fiber structure prepreg to generate the layup and the layup is positioned in a mold cavity of a matched die form. In addition, a first form of the matched die form is urged towards a second form of the matched die form to facilitate flow of a portion of the layup from an area of excess composite material in the mold cavity to an area of insufficient composite material in the mold cavity and the layup is cured to generate the composite item. | 04-22-2010 |

20100134613 | APPARATUS FOR EVALUATING PARTS - An apparatus for evaluating a part may include a camera, a camera-holding member for holding the camera in place relative to the part being evaluated, and an indexing surface disposed in a fixed position relative to the camera-holding member. The camera may be positioned to take a simultaneous picture of both the indexing surface and the part in order to evaluate the part using the picture by comparing an indexing surface image with a part image. | 06-03-2010 |

20140069576 | METHOD OF MANUFACTURING CURVED COMPOSITE STRUCTURAL ELEMENTS - A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/−45° from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away. | 03-13-2014 |

20080244366 | ADAPTABLE CHANNEL COMPENSATION FOR RELIABLE COMMUNICATION OVER FADING COMMUNICATION LINKS - A method for reducing fading channel signal data loss for serial data rates rates up to approximately 10 gigabits per second includes sequentially distributing serial data to multiple encoders. Individual data bytes are sent from the encoders to a convolutional interleaver. Each byte is distributed to an individual memory element of the interleaver in a received byte sequence. An address generator generates write and read addresses assignable to each memory element. Multiple shift registers have variably graduated lengths. The serial data is distributed between channels each having a different delay element created by shift register length differences. The delay elements are adjustable to correct data dropout due to daily atmospheric/channel changes. Fade detection signals are inserted before transmission and measured at a receiver. The fade signals help create erasure bits to improve decoding accuracy and adjust interleaver delay parameters. | 10-02-2008 |

The active chaff may include a signal generator, a signal spreading device, a microprocessor, a power source, and a substantially high-drag aerodynamic envelope. The signal generator may emit a signal to assist the aircraft in evading radar detection and/or a missile. The signal spreading device may spread the generated signal. The microprocessor may control the signal generator and the signal spreading device. The power source may power the signal generator and the microprocessor.
