  • Patent number: 7383690
    Abstract: An ice harvesting prevention mechanism, including an actuator, is provided for an ice maker. The ice maker is arranged to make, harvest and dispense ice to an ice bucket located in an ice receiving position. An ice harvesting prevention device is arranged to prevent dispensing of ice in a first position of the actuator and to permit dispensing of ice in a second position of the actuator. The ice bucket itself, or a movable button carried on the ice bucket, may engage the actuator, when the ice bucket is placed in the ice receiving position, to move the actuator from the first position to the second position. The button may be moved to an “off” position to prevent engagement with the actuator, thereby preventing dispensing of ice when the ice bucket is in the ice receiving position.

  • Patent number: 7380405
    Abstract: Implementations of the present invention include systems, methods, and apparatus for improving the fuel efficiency (mpg/kpl) of a motor vehicle during those times when the vehicle air conditioning system is operating. Whenever the driver takes his foot off the gas, or the vehicle engine is otherwise caused to decelerate, the refrigerant compressor clutch engages, allowing the compressor to operate on previously-imparted vehicle waste energy (e.g., imparted by the engine, or by downhill travel.) When the refrigerant pressure reaches a pre-set maximum value, the clutch is deactivated, and the compressor stops. When the refrigerant pressure reaches a pre-set minimum level, the clutch is activated regardless of the existence of vehicle waste energy. When the refrigerant pressure reaches another pre-set level between the aforementioned maximum and minimum levels, in the absence of any vehicle waste energy, the clutch is again deactivated and the compressor stops.
