Abstract: An information processing system includes an identification unit configured to identify unique information on shoes using at least part of a captured image of the shoes, and a setting unit configured to set an association between an acquisition device configured to acquire the unique information and a module device attached to the shoes based on the unique information.

Abstract: A vacuum switch bulb type change over switch of the invention is used for an on-load tap changer for changing over from a tap to a tap in an on-load state. The change over switch is formed of a plurality of single phase switch cassettes, and a common controller for the switch cassettes. Each cassette includes a plurality of vacuum switch bulbs and a plurality of coupling devices for the vacuum switch bulbs. The common controller includes a plurality of holding devices for holding the vacuum switch bulbs in an opened or a closed state to thereby hold the taps in predetermined states. The single phase switch cassettes are independently mounted on and coupled with the common controller through the holding device.

Abstract: Disclosed is a switching device for a tap changer comprising an input lever and an output lever rotatably attached to a shaft. The output lever is provided for making contact with a selected one of a first tap and a second tap. The output lever has a cammed surface at its base for securing a position of the output lever to make contact with the first tap and for preventing the output lever from rotating about the shaft. The device also includes a spring for pulling the output lever toward the input lever, and a clutch, rotatably attached to the shaft, which has a slot. A latching apparatus engages the clutch. The device further includes a pin which is fixedly attached to the input lever and disposed within the slot. The pin drives the clutch to engage the latching apparatus. In operation, after the input lever has been pulled away from the output lever by a predetermined angle, the pin drives the clutch to engage the latching apparatus, thereby freeing the cammed surface from the latching apparatus.
