The present invention describes a system and method for supplying
electrical power to a device, such as a filter element, located within a
housing. In one embodiment, a conductive coil is embedded into the
housing base, and a second coil is embedded into the filter element.
Current is then passed through the coil in the housing base. Through
induction, a current is created in the second coil in the filter element,
in much the same way as a transformer functions. This inductive field may
interfere with the operation of the various electronic functions, such as
communications, sensing or other activities. To overcome this issue, an
energy storage component, such as a capacitor, is included in the filter
electronics. In this way, the power generated by the inductive field can
be stored, and used when the inductive field is no longer present.
