Abstract: A neutral-grounded structure and a method for delta-connected windings are provided. The delta-connected windings include a first phase winding, a second phase winding, and a third phase winding. A grounding winding is disposed on at least one of the phase windings. The first end of the grounding winding is connected to a grounded point which is utilized as a neutral point.

Abstract: A search engine and a method achieve timeliness of documents returned in a search result by a relevancy feedback mechanism driven by the frequency in which a URL is returned in recent searches. The relevancy feedback mechanism includes one or more random processes which determine whether or not a cached or indexed web page associated with a URL in the search result should be refreshed. In addition, the random processes also determine whether or not hyperlinks in the cached or indexed web page should be followed to access related web pages. Accesses of web pages resulting from the operations of the random processes are used to update any document index maintained by the search engine. Relevancy scoring functions implemented in look-up tables are also disclosed. A more accurate relevancy scoring function is achieved using a lexicon based on anchortexts of extracted hyperlinks of web documents.

The electric conducting contact points are correspondingly associated with the charger device, a detector device and an automatic switching device. When the charger device is connected to the battery, the detector device determines size of charge current, and when the detector device determines that the charge current has not reached a set value, then the automatic switching device switches a normal charge mode to a boosting charge mode. The detector device stops the charger device from charging if the battery has already been charged for a predetermined time but has not reached a set value, and a display device displays that an abnormal state has occurred, thereby enabling the charger device to achieve the objective of providing good charging effectiveness and functionality to detect abnormalities when connecting to a battery.
