  • Publication number: 20110048056
    Abstract: A safety system for an ice and liquid dispenser of a refrigerator is used to sense the presence of human skin in a dispensing well. The safety system includes a digital image capture device focused on a dispenser well for capturing images of objects, such as hands, in the dispenser well and a digital image analyzer operatively coupled to the digital image capture device. The digital image analyzer evaluates the digital images captured by the digital image capture device to determine if human skin color is detected in the image of the object in the dispensing well. If human skin color is detected, thus indicating a hand in the dispensing area, any dispensing operation will be prevented and an alert will be provided.

  • Publication number: 20110030460
    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.
