  • Patent number: 8181472
    Abstract: An electronic microprocessor-based control system for a refrigerator is provided having refrigeration components including a compressor, a condenser, a condenser fan, an evaporator, a variable speed evaporator fan. Multiple temperature sensors are provided to communicate with the electronic microprocessor-based electronic control system. The electronic microprocessor-based control system controls the operation of both the refrigeration and non-refrigeration components based on information provided by the multiple temperature sensors.

  • Patent number: 7677053
    Abstract: A refrigeration appliance has an access door in which is located a recess containing a dispensing unit. The recess can include an upper surface, a rear surface and opposed side surfaces. The dispensing unit includes at least one of a dispensing outlet for dispensing a fluid such as water and a dispensing outlet for dispensing ice. The dispensing unit also includes at least one emitting source for emitting a beam of light and a respective receiver for receiving the beam of light from each of the at least one emitting source. Each of the at least one emitting source and the respective receiver comprise a light couple. The emitting source and receiver of each light couple are arranged so that the light passing between the emitting source and the receiver passes substantially vertically beneath at least one of the at least one of a dispensing outlet for dispensing a fluid and a dispensing outlet for dispensing ice.
