Abstract

Aspects herein include filter systems including short-range wireless tracking features to detect insertion and/or removal of filter elements from filter systems. In an embodiment, a filtration system is included having a housing including a fluid inlet and a fluid outlet. The housing can define an internal volume. A first filter element can be removably disposed within the housing. A short-range wireless communication tag can be associated with the first filter element. A short-range wireless communication reader can be associated with the housing, the reader configured to wirelessly send data to and receive data from the tag when the reader and the tag are at a distance that is less than or equal to a maximum communication distance. Removal of the first filter element from the housing can cause the distance between the tag and the reader to exceed the maximum communication distance. Other embodiments are also included herein.

First claim

The invention claimed is:

1. A filtration system comprising:
a housing comprising a fluid inlet and a fluid outlet, the housing defining an internal volume configured to receive a first filter element including a short-range communication tag within the housing;
a short-range wireless communication reader associated with the housing, the reader configured to wirelessly send data to and receive data from the short-range wireless communication tag of the first filter element when the short-range wireless communication reader and the short-range wireless communication tag are at a distance that is less than or equal to a maximum communication distance;
a system controller;
wherein the system controller is configured to receive electrical signals from the short-range wireless communication reader and identify filter removal events based on interruption of communication between the short-range wireless communication tag and the short-range wireless communication reader; and
wherein the short-range wireless communication tag is configured to store data regarding any of a pressure drop of the filtration system, a pressure drop change of the filtration system, hours of usage of the filter element, installation dates and times of the filter element, and counts of installation events of the filter element.

2. The filtration system of claim 1 , wherein the internal volume is configured to receive a first filter element comprising a cylindrical exterior shape.

3. The filtration system of claim 1 , wherein the fluid inlet and the fluid outlet are located adjacent a first end of the housing.

4. The filtration system of claim 3 , the housing defining a removable cover connected to a second end of the housing, the second end on an opposite side from the first end of the housing, wherein removal of the removable cover allows access to an aperture on the housing that is sufficiently large for the first element to pass through, the system further comprising a short-range wireless communication tag disposed on or within the removable cover in order to detect cover removal events.

5. The filtration system of claim 4 , wherein the short-range wireless communication tag is a near-field communication (NFC) tag.

6. The filtration system of claim 4 , the system configured to increment and store a count of detected cover removal events or reinstallation events.

7. The filtration system of claim 3 , wherein the short-range wireless communication reader is disposed adjacent the first end of the housing.

8. The filtration system of claim 1 , wherein the fluid inlet is located adjacent a first end of the housing, wherein the fluid outlet is located adjacent a second end of the housing, the first end being disposed on an opposite side of the housing as the second end.

9. The filtration system of claim 1 , wherein the maximum communication distance is less than or equal to 8 inches.

10. The filtration system of claim 1 , wherein the maximum communication distance is less than or equal to 20 centimeters.

11. The filtration system of claim 1 , wherein the interruption has a duration exceeding 0.5 seconds.

12. The filtration system of claim 1 , the system configured to increment and store a count of detected filter element removal events.

13. The filtration system of claim 12 , the count of detected filter element removal or reinstallation events configured to be stored in a memory circuit that is part of the short-range wireless communication tag disposed on the first filter element.

14. The filtration system of claim 1 , the system further comprising a latch actuation sensor, the system configured to increment and store a count of latch actuation events.

15. The filtration system of claim 1 , the housing comprising a side wall and an end wall, wherein a length of the side wall exceeds the maximum communication distance.

16. The filtration system of claim 1 , wherein the short-range wireless communication tag is a near-field communication (NFC) tag.

17. The filtration system of claim 1 , wherein there is substantially no liquid between the short-range wireless communication tag and the short-range wireless communication reader when the short-range wireless communication reader and the short-range wireless communication tag are at a distance that is less than or equal to a maximum communication distance.

18. The filtration system of claim 1 , wherein the system controller is configured to receive electrical signals from the short-range wireless communication reader and identify patterns comprising at least one “ON” phase at least one “OFF” phase reflecting filter removal events in the electrical signals received from the short-range wireless communication reader;
wherein the “OFF” phase corresponds to periods of no communication between the short-range wireless communication tag and the short-range wireless communication reader and the “ON” phase corresponds to periods of communication between the short-range wireless communication tag and the short-range wireless communication reader.

19. The filtration system of claim 1 , wherein the short-range wireless communication reader is configured to send and receive the data from the short-range wireless communication tag through a housing of the filtration system.
