ABSTRACT:
A method and apparatus for powering one or more remotely-situated devices. In accordance with some embodiments of the invention, energy is added (at a convenient location) to a medium that the remotely-situated devices are associated with (e.g., a medium that the remotely-situated devices are sensing, controlling, alarming, etc). The energy is removed from the medium near to the remotely-situated devices. If required, the energy is converted to a form that is useable by the remotely-situated device. The removed energy is delivered to the remotely-situated devices and is used by them to perform an action that is associated with the medium (e.g., sensing a characteristic of the medium, controlling a characteristic of the medium, providing an alarm responsive to a value of a characteristic of the medium, etc.
