Abstract:
A water filter assembly is provided. The water filter assembly includes a filter cartridge removably mounted to a manifold. An RFID tag is positioned at an outer surface of the filter cartridge. The water filter assembly also includes a liquid collector positioned below the filter cartridge. The liquid collector is positioned for receiving liquid leaking from the water filter assembly. A system for detecting liquid is also provided.
Abstract:
Systems and methods for detecting a contamination status of an ultrasonic sensor assembly included in a refrigeration appliance are provided. An exemplary refrigerator includes a sensor assembly. The sensor assembly includes a first ultrasonic sensor configured to transmit an ultrasonic signal and a second ultrasonic sensor configured to receive the ultrasonic signal. The refrigerator is configured to perform operations comprising detecting whether the sensor assembly is contaminated based on one or more characteristics of the received ultrasonic signal. An exemplary method includes monitoring a change in a characteristic of a plurality of crosstalk components of a plurality of ultrasonic signals of over a period of time to detect a contaminated state of an ultrasonic sensor.

Abstract:
An improved sensor assembly is provided that allows for close proximity detection of one or more objects by isolating a first sensor from a second sensor within the sensor assembly using isolation boots and a unique mounting structure. Each sensor has at least a portion positioned within an isolation boot, and the isolation boots are supported between a base plate and a support plate by one or more base plate ribs and one or more support plate ribs. The sensor is therefore prevented from otherwise contacting the base plate or the support plate.

Abstract:
Methods for operating a sensor of a refrigerator appliance are provided. In the methods, at least one of a detection threshold of the sensor, a power output of a transducer of the sensor, or a gain of an amplifier of the sensor can be adjusted. Through such adjustments, accuracy and precision of measurements taken with the sensor can be improved.
Abstract:
A refrigerator appliance and a method for monitoring a water filter assembly within the same are provided. The method includes monitoring signal communication between an RFID tag of the water filter assembly and an RFID reader of the refrigerator appliance and terminating a flow of water to the water filter assembly if the signal communication between the RFID tag of the water filter assembly and the RFID reader of the refrigerator appliance is lost or disrupted.

Abstract:
Methods for monitoring a sensor of a refrigerator appliance are provided. The methods include activating an auto-fill feature of the refrigerator appliance and receiving a signal from a sensor of the refrigerator appliance. The method also includes displaying a message on a display of the refrigerator appliance if the sensor does not detect the container within the dispenser recess. The message can provide a user with feedback regarding the auto-fill feature and assist the user with properly operating the auto-fill feature.
