摘要： A computer software product adapted for use in a weld inspection system is executed by a processor and is stored in an electronic storage medium of the weld inspection system adapted to facilitate the inspection of a weld of a work product. The computer software product includes a first module and a combination module. The first module is configured to transform first and second raw thermal images, associated with respective first and second heat pulses of at least a portion of the work product having the weld, into respective first and second binary images. The combination module is configured to transform the first and second binary images into a combined binary image for the reduction of noise.

摘要： A system for evaluating a battery cell includes an imaging device configured to take an image of at least part of the battery cell, and a processor. The processor is configured to perform: determining a region of interest in the acquired image, reducing a sharpness of the acquired image to generate a reference image, comparing the acquired image and the reference image, and identifying a discontinuity of the battery cell based on a difference between the acquired image and the reference image.

摘要： A weld inspection system is adapted to inspect a weld of a work product via thermographic technology. The weld inspection system includes a heat source assembly, a thermal imaging camera, and a controller. The heat source assembly is adapted to sequentially direct a plurality of heat pulses upon the work product from varying perspectives and within a pre-determined time period. Thea thermal imaging camera is configured to thermally image the weld over the pre-determined time period and collect thermal imaging data of heat dissipation from the work product. The thermal imaging data is associated with the weld and the plurality of heat pulses. The controller is configured to control the heat source assembly and the thermal imaging camera. The controller includes a processor configured to receive and transform the thermal imaging data into a binary image for evaluation of the weld.

摘要： A lap belt pretensioner for a lap belt configured to secure an occupant of a vehicle seat includes a pyrotechnic device. The pyrotechnic device is configured to generate a force directed to tension the lap belt around the occupant and emit an exhaust gas including particulates at high pressure and high temperature as a byproduct of the generated force. The lap belt pretensioner also includes a housing configured to retain the pyrotechnic device and defining an exhaust passage configured to expel the exhaust gas from the lap belt pretensioner. The lap belt pretensioner additionally includes a shield arranged over the exhaust passage and configured to collect and/or deflect the emitted particulates and dissipate heat energy thereof. A vehicle having the vehicle seat mounted to the vehicle structure and employing the seatbelt system is also provided.

摘要： A method and an apparatus for evaluating a battery cell. The battery cell may include a hermetically sealed outer casing, a plurality of electrically conductive components enclosed within the outer casing, an electrically conductive terminal having a proximal end that extends within the outer casing and a distal end that extends in a longitudinal direction relative to the battery cell outside the outer casing, and a solid electrical and mechanical joint formed between one or more of the electrically conductive components and the proximal end of the electrically conductive terminal. Evaluation of the battery cell may include measuring the impedance of the battery cell while applying a longitudinal pulling force or a transverse bending force to the electrically conductive terminal and the solid electrical and mechanical joint.

摘要： A system for evaluating a battery cell includes an imaging device configured to take a first image of at least part of the battery cell when the battery cell is in a first deformation state, and take a second image of the at least part of the battery cell when the battery cell is in a second deformation state. The system also includes a processor configured to analyze the first image and the second image, identify a first region of the first image that represents a suspected discontinuity, the first region corresponding to a portion of the battery cell, compare the first region of the first image to a second region of the second image, the second region corresponding to the portion of the battery cell, and determine that the suspected discontinuity is an actual discontinuity based on a difference between the first region and the second region.

摘要： An apparatus for in-situ monitoring of a workpiece includes a fluidic container defining a cavity and having a peripheral portion that defines an aperture. The fluidic container contains an acoustic transmission fluid. A conformable membrane is sealably disposed about the peripheral portion of the aperture of the fluidic container. The conformable membrane is disposed to sealably contain the acoustic transmission fluid within the fluidic container and to conform to a surface of a portion of the workpiece absent an interposed fluid. An acoustic source transducer is disposed in the cavity of the fluidic container and in contact with the acoustic transmission fluid. The acoustic source transducer is disposed to generate a first acoustic wave in the direction of the workpiece. An acoustic receiving transducer is disposed to monitor a residual acoustic wave that is reflected from the workpiece in response to the first acoustic wave.
