A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

A filter element has a filter body which is closed on at least one end face by an end disc, wherein the end disc is formed from a potting compound, and has a stabilization device which is surrounded at least in some areas by the potting compound. At least one data storage unit is arranged on or in the stabilization device.

A water purification tumbler includes a main body and a filtration unit. The filtration unit includes an annular wall, a flow conducting member, a high-temperature bamboo charcoal layer, and a low-temperature bamboo charcoal layer. The flow conducting member is disposed inside of the annular wall and defines a flow channel communicating with an opening of the main body. The flow channel has a water inlet section and a water outlet section. The water inlet section gradually narrows downward. The high-temperature bamboo charcoal layer and low-temperature bamboo charcoal layer are connected to the flow conducting member and are disposed respectively above and under the flow channel.

Various example embodiments relate to a filtration system. The filtration system comprises a housing having a first housing end and a second housing end. The housing defines a central compartment therein. The housing comprises a key slot disposed on the first housing end and a housing key element protruding from the first housing end toward the second housing end. The filtration system further comprises a filter element positioned within the central compartment of the housing. The filter element has a first filter end and a second filter end. The filter element includes filter media and an endplate disposed on the first filter end. The endplate includes a central endplate opening, a key element configured for engagement with the key slot, and an installation guidance element formed along the central endplate opening. The installation guidance element is configured for engagement with the housing key element.

An anti-counterfeiting mechanism for a filter element to specifically, and preferably uniquely, identify a filter with a conductive pattern or path of conductive materials preferably either embedded (thin film circuit) under the surface, or over molded on, a portion of the filter. The conductive materials are preferably positioned at the filter end cap. The resistance of the filter element is an identifier that is preferably associated with the OEM manufacturer's labeling (such as product number) and/or other branding of the component. This electrical resistance signature permits rapid identification of counterfeit filters.

A sensing system for detecting degradation of a machine fluid is disclosed. The sensing system may comprise a tag having electrical contacts. The tag may be configured to transmit a wireless signal when the electrical contacts are in electrical communication. The sensing system may further comprise a dissolvable element separating the electrical contacts and obstructing electrical communication between the electrical contacts. The dissolvable element may be configured to dissolve and allow electrical communication between the electrical contacts when an acid content of the machine fluid reaches a level indicative of the degradation of the machine fluid.

Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

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 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.
