摘要： An airfoil-magnetic hybrid bearing, which is a combination of a magnetic bearing and airfoil bearing includes a housing, an airfoil bearing, a magnetic bearing, coils, and a coupling segment. The housing is around a rotating shaft of a rotation device. The airfoil bearing is positioned between the housing and the rotating shaft to form dynamic pressure to levitate the rotating shaft during rotation of the rotating shaft. The magnetic bearing includes cores positioned radially between inner surface of the housing and outer surface of the airfoil bearing. The cores are projected to the center of the rotating shaft. The coils wound to the cores to levitate the rotating shaft using a magnetic attractive force generated by a current application thereto. The coupling segment is configured to couple the airfoil bearing to the magnetic bearing directly.

摘要： There is provided an electronic shelf label including an image display unit displaying a first image; a sensor unit detecting image switching signals; and a processor unit determining whether the image switching signals detected by the sensor unit are valid and switching the first image displayed on the image display unit to a second image when the image switching signals are valid, and a communication unit receiving a plurality of image data displayed on the image display unit. The processor unit determines that the image switching signals are valid when a detection duration time of the image switching signals is longer than a predetermined first threshold time. By this configuration, the electronic shelf label can switch a plurality of images and reduce the influence of disturbance to thereby prevent unnecessary image switching. Further, the electronic shelf label can provide product-related information for a manager or the like as well as for a purchaser.
