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.
