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： Methods and systems for detecting partial discharge in a stator for an electric motor are provided. An exemplary method includes applying a high voltage AC sinewave input signal to the stator and energizing at least one winding therein. The method includes sensing a first resulting load signal occurring in the stator with a first device and filtering the first resulting load signal to form a first high frequency signal indicating any partial discharge (PD) voltage occurring in the stator. The method also includes sensing a second resulting load signal occurring in the stator with a second device and filtering the second resulting load signal to form a second high frequency signal indicating any partial discharge voltage occurring in the stator. Further, the method includes processing the first and second high frequency signals to form a processed signal indicating whether partial discharge occurred.

摘要： A method of analyzing the quality of a battery cell includes performing a high-throughput quality check on the battery cell with a quality control system, assessing a quality score to the battery cell, with quality score identifying the battery cell as low-quality or high-quality, and performing a comprehensive quality check on the battery cell if identified as low-quality. The method further includes assessing an enhanced quality score to the battery cell superseding the quality score of the quality control system identifying the battery cell as confirmed low-quality or confirmed high-quality and providing revised production instructions for manufacturing successive battery cells if confirmed low-quality.

摘要： A partial discharge calibration standard apparatus may include a first and second rigid members defining respective first and second facing surfaces. An electrically insulating material may be disposed between the facing surfaces. The apparatus may further include a pressure member maintaining the rigid members together, thereby fixing the first and second facing surfaces in a substantially parallel spaced relation across the insulating material such that a partial discharge threshold magnitude for an electrical potential difference between the first and second facing surfaces is determined. The insulating material may prevent a partial discharge of an electrical potential from the first facing surface to the second facing surface below the partial discharge threshold magnitude, while allowing the electrical potential difference to be discharged from the first facing surface to the second facing surface through the insulating material when the electrical potential difference is increased to the partial discharge threshold magnitude.

摘要： A quality control system analyzes the quality of a battery cell, with the battery cell defining a gas pouch configured to expand from a deflated configuration to an inflated configuration when filled with a gas formed during a cell formation process. The system comprises a computational system comprising a processor and a memory and a measurement instrument in electronic communication with the computational system. The measurement instrument is arranged to measure a distance defined by the gas pouch and transmit a signal to the computational system corresponding to the distance. The computational system is arranged to analyze the distance with the processor and determine a volumetric measurement of the gas within the gas pouch and compare the volumetric measurement to a threshold in the memory to assess a quality score for the battery cell. A corresponding method analyzes the quality of the battery cell with the quality control system.

摘要： An arc welding/brazing process is disclosed that is useful to join together a first copper piece and a second copper piece without damaging more heat-sensitive materials that may be located nearby is disclosed. The arc welding/brazing process includes using a non-consumable electrode wire, which electrically communicates with a weld control in a straight polarity orientation, to strike an arc across a gap established between a leading tip end of the electrode wire and the first copper piece. The current that flows through the arc when the arc is established heats the first copper piece such that the first copper piece becomes joined to a second copper piece. The joint between the first copper piece and the second copper piece may be an autogenous weld joint or a braze joint.

摘要： A manufacturing fixture includes a rigid base defining a control plane. A first cone locator pin has a first longitudinal axis. The first cone locator pin is connected to the rigid base with the first longitudinal axis orthogonal to the control plane to engage a complementary locating aperture defined in a workpiece. The first cone locator pin engages the complementary locating aperture to locate the workpiece and constrain translation of the workpiece with respect to the control plane. A second cone locator pin has a second longitudinal axis. The second cone locator pin is connected to the rigid base with the second longitudinal axis orthogonal to the control plane to engage a complementary locating hole defined in a workpiece. The second cone locator pin engages the complementary locating hole to locate the workpiece and prevent rotation of the workpiece about the first longitudinal axis.
