  • Patent number: 11215444
    Abstract: A method of identifying the material and determining the physical thickness of each layer in a multilayer structure is disclosed. The method includes measuring the optical thickness of each of the layers of the multilayer object as a function of wavelength of a light source and calculating a normalized group index of refraction dispersion curve for each layer in the multilayer structure. The measured normalized group index of refraction dispersion curves for each of the layers is then compared to a reference database of known materials and the material of each layer is identified. The physical thickness of each layer is then determined from the group index of refraction dispersion curve for the material in each layer and the measured optical thickness data. A method for determining the group index of refraction dispersion curve of a known material, and an apparatus for performing the methods are also disclosed.

  • Publication number: 20210065085
    Abstract: In an example, a method is performed by a computing system that is one of a group of computing systems involved in facilitating a manufacturing of an aircraft. The method comprises generating a plurality of manufacturing task work statements (MTWSs), each MTWS being associated with a task involved in the manufacturing and comprising smart contract data and computer code. The method also comprises receiving system state information indicating (i) a schedule according to which the aircraft is to be manufactured, (ii) resources available for use in executing the MTWSs, and (iii) one or more aircraft certification requirements with which the tasks involved in the manufacturing of the aircraft are to comply. The method also comprises executing the MTWSs based on the system state information and storing, in a blockchain-based distributed ledger accessible by the group of computing systems, an end state result of the execution of each MTWS.

  • Patent number: 10070791
    Abstract: An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image from the tooth and a second spectral range for exciting a fluorescence image from the tooth. A polarizing beamsplitter in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor, wherein the second polarization state is orthogonal to the first polarization state. A first lens in the return path directs image-bearing light from the tooth toward the sensor, and obtains image data from the portion of the light having the second polarization state. A long-pass filter in the return path attenuates light in the second spectral range.

  • Patent number: 9665817
    Abstract: A computer-implemented technique can receive, at a computing device, a uniform resource locator (URL) for a web page and an image. A number of pixels corresponding to a desired resolution for encoding the image is determined and the image is converted to a modified image having the desired resolution. The technique can then generate a two-dimensional barcode by: (i) generating first data representative of the modified image, (ii) appending the first data to either an end of the URL to obtain a first modified URL or after a terminator bit of the two-dimensional barcode, (iii) generating second data representative of the second modified URL or the URL, and (iv) generating third data representative of an error correction code (ECC) based on the first data and the second data, wherein the two-dimensional barcode is generated based on the first data, the second data, and the third data.

  • Patent number: 9551790
    Abstract: A method including placing first and second measurement devices proximate first and second aircraft doors, respectively, and determining a first position of the second measurement device relative to a second position of the first measurement device. The method includes placing first and second pluralities of reflective devices inside the aircraft proximate the first and second doors, respectively. The method includes measuring first and second distances from the first and second measurement devices to the first and second pluralities of reflective devices, respectively, and measuring second distances from the second measurement device to the second plurality of reflective devices. Based on a determined position of the second measurement device and further based on the first distances and second distances, third distances are determined between each of the first and second pluralities of reflective devices. The third distances provide a measurement baseline for points on a fuselage and wings.

  • Publication number: 20160180842
    Abstract: A method and apparatus derive a dynamic grammar composed of a subset of a plurality of data elements that are each associated with one of a plurality of reference identifiers. The present invention generates a set of selection identifiers on the basis of a user-provided first input identifier and determines which of these selection identifiers are present in a set of pre-stored reference identifiers. The present invention creates a dynamic grammar that includes those data elements that are associated with those reference identifiers that are matched to any of the selection identifiers. Based on a user-provided second identifier and on the data elements of the dynamic grammar, the present invention selects one of the reference identifiers in the dynamic grammar.
