An IC tag is attached to a filter element and a contact of the IC tag with liquid is avoidable. An IC tag is provided inside an upper plate provided so as to cover an upper end surface of a filter medium in a filter element. A lid body is provided on the case into which the filter element is inserted, and an antenna is provided on the lid body.

An all-in-one manifold assembly is fabricated separately from and coupled to a pressure vessel of a water filter system. The manifold assembly includes two valve assemblies configured to be rotated between an operational position, a by-pass position and a shut-off position. Rotation of the valve assemblies can occur by manual or automatic rotation. The manifold assembly may further include ports for one or more sensors. A controller can smartly operate the manifold assembly.

A valve box assembly includes a pipe within the valve box assembly, a valve coupled to the pipe and a radio-frequency identification tag within the valve box assembly.

A silt and debris catching apparatus comprises a housing component and a catchment component. The housing component is adapted to fit within a valve box assembly. The catchment component is coupled to the housing component and includes a filter. The filter retains material that enters the valve box assembly.

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.

A filter device may include a filter housing and a ring filter element arranged upright in the filter housing in an installed state. The ring filter element may include an upper end disc, a lower end disc, and at least two projecting pins, each of which in the installed state may engage in an associated draining passage. One of the connecting pins may be arranged offset relative to another of the connecting pins by at least 120 in a circumferential direction of the ring filter element.

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.

The invention relates to a filter device with a removable termination part (81; 82) and a housing (3) that receives a replaceable filter element (5) having two end caps (25,47), between which a filter material (12) extends. The invention is characterized in that a positioning device (65) is arranged between the termination part (81; 82) and one end cap (47), said positioning device positioning the filter element (5) within the housing (3), at least when viewed in the circumferential direction of the filter element, in interaction with at least one corresponding positioning element (71) of said end cap (47).

The application generally relates to digital Engine Integrity Protection (EIP) systems for filters for internal combustion engines and methods of using the digital EIP systems. A pre-programmed digital chip is integrated in filtration hardware such that the Engine Control Unit (ECU) or another controller installed on the engine or vehicle can read encrypted digital signal from the chip when electrically connected with the filter hardware. Based on the read information from the chip, the ECU or controller can determine whether the filter associated with the chip is a genuine filter or a non-genuine filter.

A filter assembly for authenticating a filter cartridge includes a filter housing and an optical scanner mounted to the filter housing. A controller uses the optical scanner to take one or more digital images of the filter cartridge and obtain digital coded data identifying the filter cartridge. Specifically, the controller locates a functional locator on the filter cartridge, determines a location of an identifying region on the filter cartridge, reads the digital coded data by interrogating the identifying region with the optical scanner, and determines that the filter cartridge is authentic based at least in part on the digital coded data.
