Abstract: A filter housing assembly for fluid filtration which may be attached to, and removed from, a filter base by a push-actuated release. The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.

Abstract: A filtration system interconnection structure having a filter manifold and a filter cartridge in magnetic communication with one another, such that a latching mechanism and latch blocking structure in the manifold secures the filter cartridge with a manifold sump when the filter cartridge is inserted within the manifold sump. The magnetic communication is formed between two complementary coded magnets capable of producing a magnetic shear force when in close proximity to one another. The magnetic shear force removes the latching blocking structure from interfering with the latch, allowing the latch to secure the filter cartridge. Movement of the latching blocking structure coded magnet relative to the filter cartridge coded magnet may be perpendicular or parallel with respect to each other. The filter magnet polarity transitions are aligned with the manifold magnet polarity transitions such that a shear force is generated between the magnets when the filter cartridge is inserted within the manifold sump housing, allowing for actuation of the latch blocking mechanism against a biasing force, and allowing the latch to move radially inwards against a separate biasing force.

Abstract: A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

Abstract: A gravity-fed filtration system and method of initiating flow from a filter cartridge to a holding reservoir for a gravity-fed filtration system. The method comprises providing a filter cartridge having a filter magnet, a holding reservoir for filtered fluid, and a first reservoir having a recess receiving cavity in a bottom surface thereof for receiving ingress fluid. Upon inserting the filter cartridge into the recess receiving cavity and moving the filter magnet to be in in magnetic communication with the carrier magnet, a magnetic force moves the carrier magnet from a first position which blocks fluid flow, to said second position which allows fluid flow to the holding reservoir.

Abstract: A gravity-fed filtration system interconnection structure comprising a reservoir for receiving ingress fluid, and a second, dispensing reservoir. A carrier or shuttle having a carrier magnet is connected to a sluice gate valve which normally blocks the opening to the second reservoir. A filter cartridge may be received by the reservoir and includes a housing body, and a filter magnet disposed within or fixedly connected to the housing body. The filter magnet and the carrier magnet are interconnected via magnetic communication upon insertion of the filter cartridge into the reservoir recess, to move the carrier and/or sluice gate valve as a result of shear force or rotational force generated between the magnets.

Abstract: A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.

Abstract: A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.

Abstract: An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.
