    摘要： An anomaly detection method and system for comparing a scanned object to an idealized object is provided. The anomaly detection method includes generating a three-dimensional reference model of the idealized object. The anomaly detection method further includes acquiring at least one two-dimensional inspection test image of the scanned object. The anamoly detection method also includes determining a two-dimensional reference image from the three-dimensional reference model using multiple pose parameters, wherein the two-dimensional reference image corresponds to the same view of the three-dimensional reference model of the idealized object as the view of the two-dimensional inspection test image of the scanned object. The anamoly detection method further includes identifying one or more defects in the inspection test image via automated defect recognition technique.

    摘要： A vibration damper includes a hub, a first mass, a first resilient coupling, a second mass, and a second resilient coupling. The first mass is disposed concentrically about the hub. The first resilient coupling resiliently couples the first mass to the hub. The first resilient coupling has a first spring constant. The second mass is disposed concentrically about the first mass. The second resilient coupling resiliently couples the second mass directly to the first mass. The second resilient coupling has a second spring constant that is less than the first spring constant. The first mass and the first resilient coupling are configured to attenuate vibration at a first frequency. The second mass and the second resilient coupling are configured to attenuate vibration at a second frequency. The second frequency is lower than the first frequency.

    摘要： A method for attenuating vibration in a driveline having a shaft assembly that transmits torque between first and second driveline components. The shaft assembly can have a hollow shaft member and at least one liner. The liner has a mass and a stiffness that are tuned such that the liner is a tuned resistive absorber for attenuating shell mode vibrations as well as at least one of a tuned reactive absorber for attenuating bending mode vibrations and a tuned reactive absorber for attenuating torsion mode vibrations. The tuned liner is inserted into the shaft member.

    摘要： A propshaft assembly includes a shaft structure having a hollow cavity and an insert member being positioned within the hollow cavity and engaging the shaft structure. The shaft structure vibrates in response to receipt of an input of a predetermined frequency such that a shell mode anti-node is generated. The insert member is located at a position that approximately corresponds to the anti-node and has a compressive strength that is tailored to an anticipated displacement of the anti-node to thereby attenuate vibration of the shaft structure.

    摘要： An event clustering method uses foreground and background segmentation for clustering images from a group into similar events. Initially, each image is divided into a plurality of blocks, thereby providing block-based images. Utilizing a block-by-block comparison, each block-based image is segmented into a plurality of regions comprising at least a foreground and a background. One or more luminosity, color, position or size features are extracted from the regions and the extracted features are utilized to estimate and compare the similarity of the regions comprising the foreground and background in successive images in the group. Then, a measure of the total similarity between successive images is computed, thereby providing image distance between successive images, and event clusters are delimited from the image distances.

    摘要： A method for determining the noise level, as characterized by the standard deviation, of an input video sequence corrupted by unknown noise comprises the steps of: (a) spatiotemporally filtering the input video sequence, thereby producing a filtered video sequence; (b) estimating a standard deviation from the difference between the input video sequence and the filtered video sequence, thereby producing an estimated standard deviation; and (c) iterating through steps (a) and (b) using the estimated standard deviation previously obtained from step (b) to perform the filtering in step (a) until the value of the noise level approaches the unknown noise, whereby the noise level is then characterized by a finally determined standard deviation.

    摘要： A method for evaluating energy transmission from an axle through a vehicle suspension system. The methodology employs a torsional actuator to apply input energy to the vehicle in a manner that mimics the energy that is generated by the axle during the operation of the vehicle so that both the driving load and the vibration induced by gearset motion variation are simulated. Since the energy input can be quantified and monitored, the same amount of torque can be applied during each test to permit the technician to fully comprehend differences in the designs of several axles on the transmission of noise and vibration.
