Power extracting device and method of use thereof

摘要

A structure is provided. The structure includes a signal retrieval circuit formed within a disk located within a coaxial cable connector. The signal retrieval circuit is located in a position that is external to a signal path of an electrical signal flowing through the coaxial cable connector. The signal retrieval circuit is configured to extract an energy signal from the electrical signal flowing through the coaxial cable connector. The energy signal is configured to apply power to an electrical device located within the coaxial cable connector. The structure may additionally form a sensing circuit with a status output component. The sensor circuit may be configured to sense physical parameters such as those related to a condition of the electrical signal flowing through the connector or a presence of moisture within the connector.
