SYSTEM AND METHOD FOR COMMUNICATION BETWEEN A FLUID FILTRATION APPARATUS AND FILTER
First Claim
1. A system allowing the wireless transfer of data between a fluid filtering apparatus and a filter when the filter is positioned within the fluid filtering apparatus, the system comprising:
- a reader circuit operatively connected to the fluid filtering apparatus, the reader circuit having a controller;
a tag circuit operatively connected to the filter for passive wireless communication with the reader circuit, the tag circuit containing coded read-only information readable by the reader circuit authorizing use of the filter with the fluid filtering apparatus, and wherein the tag circuit includes an enable bit responsive to a disable signal from the reader circuit to permanently de-authorize use of the filter with the fluid filtering apparatus.

Abstract
A system allowing the wireless transfer of data between a fluid filtering apparatus having a controller and a filter when the filter is positioned within the fluid filtering apparatus is described. The system includes a reader circuit and tag circuit in which the tag circuit includes read-only information and an enable bit responsive to a disable signal from the reader circuit to permanently de-authorize use of the filter with the fluid filtering apparatus. The controller is operatively connected to the reader circuit for interpreting the coded information and may modify or eliminate fluid flow within the fluid filtering apparatus, and/or provide a visible or audible warning to the user on the basis of filter manufacturer specifications such as volume and/or time of filter use.

15. A method of changing the status of a filter in a fluid filtration apparatus, the fluid filtration apparatus having a controller and a reader circuit operatively coupled to a tag circuit in which the tag circuit is operatively connected to the filter, the method comprising the steps of:
-
a) isolating an enable bit within tag identification logic within the tag circuit; and b) applying a disable signal to enable in order to permanently destroy the enable bit.
