  • Publication number: 20130008556
    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.

  • Patent number: 8327889
    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.

  • Publication number: 20120144600
    Abstract: An apparatus and method for detecting an imbalance in the laundry load and effecting a redistribution of the imbalance by reducing the rotational speed of the treating chamber such that part of the load may redistribute while part of the load remains satellized, without ceasing rotation, and increasing the rotational speed back to a spin speed after redistribution.

  • Publication number: 20120138092
    Abstract: An automatic dishwasher and a method for controlling the operation of the automatic dishwasher including an imaging device that repeatedly captures images of a sub-portion of a wash chamber as a dish rack is moved from a load position to a use position. The repeated capturing of images is synchronized with the movement of the dish rack, and areas of the dish rack in which dishes are present are determined from the repeatedly captured images.

  • Patent number: 8186227
    Abstract: A method for determining the amount of laundry in a laundry treating appliance comprises determining a first load amount based on a characteristic of the oscillating of a drum and determining if the first load amount satisfies a load amount threshold. When the first load amount satisfies the load threshold, the drum may be rotated in accordance with a laundry inertia algorithm to determine inertia of the load. The second load amount may then be determined based on the inertia of the laundry.

  • Patent number: 8156748
    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.
