Abstract: A connection detecting method includes detecting at least three points not in the same line on a passive component of a connector, and determining a connection status of said connector based upon detecting results of the at least three points on the passive component of the connector.

Abstract: An electronic system, connection failure reporting system and related methods. An electronic system may include a passive component of a connector; a detecting unit configured to detect presence of an active component of the connector in at least three points not in the same line on the passive component of the connector; and a connection status determining unit configured to determine a connection status of said connector based upon detecting results of the at least three points on the passive component of the connector. A connection problem of the connector can be identified, including identification of the type of connection failure.

Abstract: An equipment management system. A detector detects at least one protector in a detection field thereof utilizing wireless communication techniques. A database stores an equipment rule for an area. The equipment rule comprises predetermined types of protectors and predetermined number for each type. A processor automatically determines if the equipment rule is satisfied by determining if the types of protectors actually detected in a period and the number of each detected type are equal to the predetermined types and numbers.
