  • Patent number: 10162317
    Abstract: A method and apparatus for controlling a tooling operation to be performed by a tooling system in an assembly process. A current set of parameter values for a set of parameters for the tooling system are modified iteratively, until the current set of parameter values are determined to result in the tooling operation producing an output that meets a set of criteria, to form a final set of parameter values. The tooling operation is performed with the tooling system using the final set of parameter values. A determination is made as to whether the output of the tooling operation meets the set of criteria based on sensor data about the output. A new set of parameter values are identified as the current set of parameter values to be evaluated in response to a determination that the output of the tooling operation does not meet the set of criteria.

  • Patent number: 9359997
    Abstract: A system and method for generating electricity from acoustic energy from an aircraft on a runway. Acoustic wave collectors mounted along the runway collect the acoustic energy and direct such acoustic energy to an associated acoustic converter assembly. A vibrating element is mounted within a housing of the acoustic converter assembly. The vibrating element moves in response to the acoustic energy. This movement draws air into the housing below the vibrating element and then forces the air downward to form an output air flow. The output air flow is directed to an associated turbine assembly to cause a shaft to rotate at a rate proportional to the magnitude of the received output air flow. An associated generator that is coupled to the shaft generates electricity proportionally to the rate of rotation of the shaft. The electricity from each generator is converted and sent to a substation for distribution.

  • Patent number: 9321099
    Abstract: An ultrasonic riveting tool and an associated method for installing a rivet are provided. The ultrasonic riveting tool and the associated method rely upon acoustic energy to cause the rivet to be installed. In the context of a method, a rivet is inserted into a bore defined by one or more workpieces. The rivet extends from a head to an opposed tail. The method also includes placing a bucking bar in an operative position with respect to the tail of the rivet. The method further includes applying acoustic energy to the head of the rivet to cause interaction between the rivet and the bucking bar such that the tail of the rivet is deformed. In this regard, the method may drive the rivet through the bore in response to application of acoustic energy so as to force the tail of the rivet into operative contact with the bucking bar.

  • Patent number: 8828538
    Abstract: Doped adhesive tape is used during the manufacture of aircraft, including positioning marks, covering orifices from debris, allowing locations to be marked. Any doped adhesive tape inadvertently left in sub-assemblies during the manufacturing process can be detected using backscatter X-ray inspection technology. Detection is facilitated in one embodiment by making the tape thicker, to produce an increased mass density, and in another embodiment by adding a dopant comprising an element that is readily detected by the backscatter X-ray technology. The element can be iodine, and can be incorporated into the backing layer or the adhesive layer of the tape during manufacturing. The use of both thicker tape and a dopant can be used in combination to facilitate detection. If the doped adhesive tape is detected after components are assembled using a backscatter X-ray inspection device, then the doped adhesive tape is removed.

  • Patent number: 8259903
    Abstract: Presented is a system and method for dynamically adjusting X-ray power levels to achieve consistent image quality. The method comprises estimating power and photon density based on current process parameters, comparing those estimates with reference values associated with desirable image quality, adjusting the X-ray power level in response to the operation of comparing, and then performing the operations of estimating, comparing, and adjusting so that the estimates approach the reference values. In embodiments, the estimating, comparing, and adjusting operations are performed dynamically as process parameters, such as X-ray spot size and distance to the target, dynamically change. The system comprises a database for storing the reference values and a processor for estimating the photon and power density based on current process parameters, comparing the reference values with the estimates, and outputting a signal to adjust one of the current process parameters such as X-ray power level.

  • Patent number: 8213571
    Abstract: Methods and systems for X-ray imaging enable inspection of an area of an object that is located separate and apart from a location of an X-ray generator. An X-ray imaging system includes an X-ray generator to generate X-rays. A collimator filters the generated X-rays to consolidate the generated X-rays and move the generated X-rays in a direction parallel to a centerline axis of the collimator. A small diameter tube transmits the directed X-rays and an end retainer emits the transmitted X-rays at an inspection object. A first filter of the collimator may initially filter the generated X-rays that are not parallel to the centerline axis of the collimator by passing the X-rays through a plurality of apertures. A second filter of the collimator may consolidate the generated X-rays and move the generated X-rays in a direction parallel to the centerline axis of the collimator by passing the generated X-rays through a channel.
