    Abstract: A refrigerator includes a sensing system for detecting quality of ice cubes in an ice cube storage bin. The system includes a digital image capture device coupled to a digital image analyzing system which captures digital images of the ice cube storage bin intermittently. The digital images are processed to determine a centroid of the ice mass within the bin, and the centroid is analyzed to determine whether it is located outside a predetermined acceptable boundary. A centroid outside of the acceptable range indicates an ice clumping situation. Additionally, the digital images are analyzed to determine whether ice cubes are smaller than a predetermined minimal acceptable size in order to detect stale ice. The level of ice in the bin can also be determined from the images. Notifications for clumping, stale and/or low level ice are sent to a user interface.

    Abstract: A select-fill dispensing system and method for a dispenser assembly utilizes a camera to sense a desired fill level based on the location of a user's finger with respect to a container. In use, a consumer places his or her finger along a container to indicate the desired fill level of the container. Image data from the camera is transmitted to a controller and processed for distortion correction, edge based image segmentation and morphological operations are carried out to remove background noise. The processed image data is utilized to detect the presence of the container, as well as the shape of the container, the position of the container opening, and the top and bottom points of the container. The controller provides a means for controlling the dispensing operation, including a fill rate, based on the desired fill level and the shape of the container.

    Abstract: A dispensing system includes a digital image capture device focused on a dispenser well for capturing images of containers in the dispenser well and a digital image analyzer operatively coupled to the digital image capture device. The digital image analyzer evaluates digital images of containers captured by the digital image capture device to determine physical parameters of each container placed in the dispensing well. An actual dispensing operation is automatically regulated based on characteristics of the container.

    Abstract: A refrigerator includes a sensing system for detecting multiple physical characteristics of ice cubes in an ice cube storage bin. The system includes a digital image capture device coupled to a digital image analyzing system which captures digital images of the ice cube storage bin intermittently and compares the images to detect the presence of ice clumps. In addition, the digital image analyzing system evaluates the edges, ice size and/or image intensity of the ice cubes in the images in order to determine the presence of stale ice. An algorithm is utilized to estimate the volume of ice within the bin based on the number of pixels in an ice bin image, the number of pixels of the ice within the bin, and a known volume of the ice bin. Notifications for clumped ice, stale ice and ice volume within the bin are sent to a user interface.
