Devices and methods are provided that permit efficient and selective separation of liquid biological specimens into at least two constituent components to facilitate subsequent quantitative and qualitative analysis on at least one analyte of interest in at least one of the components. The devices generally include one or more sample deposition regions supported on a base. Each sample deposition region includes a separation membrane for separating the liquid biological specimen into two different fractions. The first fraction is trapped by the separation membrane while the second fraction passes through the separation membrane and into a respective collection membrane. The separation and collection membranes are easily separable from the devices and can be utilized for further processing and analysis.

A filtration system having an undulated interlocking housing-endplate interface geometry is described. In the filtration system, a filter element endplate and a filter housing component (e.g., a shell housing, a filter mounting head, etc.) meet at an interface. The filter housing component includes an undulating or repeating pattern that meshes with a matching undulating or repeating pattern on the endplate of the filter element. The undulating or repeating pattern prevents the filter element from freely rotating with respect to the filter housing component of the filtration system.

Embodiments herein relate to multi-zone filtration monitoring systems and methods. In an embodiment, a filtration monitoring system is included having a plurality of filtration housings, a plurality of filter elements associated with the filter housings, a plurality of wireless communication tags associated with the filter elements, a plurality of zone antennas, and a wireless communication reader in wired communication with the plurality of zone antennas. The reader can be configured to wirelessly send data to and receive data from the wireless communication tags via the zone antennas. Other embodiments are also included herein.

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.

A filter base for receiving a complementary mating filter housing assembly. The filter base includes 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 filter housing assembly. The wire harness assembly includes conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The connector housing has an upper surface and an oppositely facing lower surface and is dimensioned to receive a first end portion of the one or more contacts. The contacts are flexible from a first position to a second position when a mating portion of the one or more contacts engages a mating connection surface of the filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact mating portions 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.

The invention relates to an arrangement for detecting a damage of a filter fabric (8) of a disc filter (1) at a disc filter unit comprising disc filters. The arrangement comprises a measurement bar (20) comprising two or more microphones (21), a store (45) including stored sound samples, at least one alarming means and a processing arrange-ment (43) for analyzing online sound or sound samples captured by the microphones (21). The processing arrangement (43) is connected to the microphones (21), the store (45) and the at least one alarming means. The invention also relates to a method for detecting a damage of a filter fabric (8) of a disc filter (1) at a disc filter unit.

A filter assembly with features for improved filter cartridge placement and detection are provided. The filter assembly includes a filter cartridge and a filter housing for receiving the filter cartridge. A contact member extends from the filter housing for engaging the filter cartridge when the filter cartridge in the installed position. A first contact is mounted to the contact member and a second contact is mounted to the filter cartridge such that the first contact and the second contact establish an electrical connection when the filter cartridge in the installed position.

A filter assembly for authenticating a filter cartridge includes a filter housing and an optical receiver mounted to the filter housing. A controller uses the optical receiver to receive a filter identification signal from an optical emitter positioned on the filter cartridge, obtains a reference filter identifier from a database, compares the filter identification signal to the reference filter identifier, and determines that the filter cartridge is authentic if the filter identification signal matches the reference filter identifier

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.
