Abstract: A contaminant measurement system is provided. The system is operable to detect and measure a concentration level of a preselected contaminant, e.g., lead, in water disposed within a chamber of the system. The system includes a detection agent that is operable to interact with the preselected contaminant in the water. The detection agent can be a plurality of polymeric beads or a membrane, for example. The system has a sensing circuit that includes a pair of electrodes spaced from one another and both at least partially disposed in the water. A controller is communicatively coupled with the sensing circuit and is configured to receive one or more electric signals from the sensing circuit. The controller determines a parameter indicative of the concentration level of the preselected contaminant based on the one or more electrical signals. The controller then determines and outputs the concentration level of the preselected contaminant.

Abstract: A refrigerator appliance having a dispensing system and a method for dispensing liquid into a container are provided. The dispensing system can be an autofill dispensing system. In one example aspect, the dispensing system includes a vibration generator and a measurement device. When a container is present in a preselected position, liquid is delivered to the container. As liquid fills into the container, the vibration generator propagates vibrations through the container. The measurement device detects one or more characteristics of the vibration and routes one more signals indicative of the characteristics to a controller of the system. The controller determines a liquid fill level of liquid within the container based at least in part on the signals received from the measurement device.

Abstract: A filter for a non-plumbed appliance is provided. The filter includes a filter housing defining a filter chamber. A filter medium is positioned within the filter chamber, each end of the filter medium being enclosed by an endcap formed from a resilient material, such as molded silicone or a thermoplastic elastomer. The endcaps slide on the ends of the filter media with no need for adhesive and form a fluid seal with both the filter media and the filter housing once installed. One or more fluid bypass channels may be defined by the filter housing or in the endcaps to allow water to flow as desired within the filter chamber. The resulting filter requires fewer components and less assembly time while improving filtration performance and reliability.

Abstract: A filter cartridge includes a radio frequency identification, RFID, tag positioned on a casing. A compressed cellulose foam is positioned over the RFID tag on the casing. An impermeable material is positioned over the cellulose foam on the casing at an outer surface of the casing. The impermeable material defines a passage that extends through the impermeable material to the cellulose team. The passage is configured such that water is flowable through the passage to the cellulose foam. The compressed cellulose foam is configured for wicking the water from the passage to the RFID tag.

Abstract: A system and method are directed to detecting the presence of heavy metals in a flowing fluid, such as a drinking water supply. The system includes a first chamber for receiving a filtered portion of the fluid and a second chamber for receiving an unfiltered portion of the fluid. A test device measures electrical properties of the filtered fluid in the first chamber and the unfiltered fluid in the second chamber, such as an electric potential difference, and a controller can use the measured electrical properties to detect the presence or quantity of one or more heavy metals within the fluid, such as lead, cadmium, zinc, nickel, and/or copper.

Abstract: A method for operating a refrigerator appliance includes operating a dispenser of the refrigerator appliance to initiate a flow of liquid water or ice into a container positioned within a dispensing recess of the dispenser in response to a user input at a user input panel of the refrigerator appliance, receiving one or more signals from a sensor positioned at the dispensing recess after operating the dispenser to initiate the flow of liquid water or ice into the dispensing recess, and detecting a presence of the container in the dispensing recess based at least in part on the one or more signals from the sensor only after operating the dispenser to initiate the flow of liquid water or ice into the dispensing recess. A related refrigerator appliance is also provided.

Abstract: A passive fluid dosing assembly and system is provided. The passive fluid dosing system may include a passive dosing body, a pressure plate, and a treatment enclosure. The passive dosing body may define a primary flow path and a liquid treatment path. The primary flow path may be defined between a fluid inlet and a fluid outlet. The liquid treatment path may be defined between a high pressure port and a low pressure port, bypassing a portion of the primary flow path. The pressure plate may be disposed within the passive dosing body between the high pressure port and the low pressure port. The pressure plate may define an internal orifice. The treatment enclosure may be positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path. The treatment enclosure may define a solute chamber housing a dosed media.
