  • FILTRATION APPARATUS AND METHOD
    Publication number: 20080128355
    Abstract: A method of delivering filtered water includes exerting a first pressure against a first side of a diaphragm. A second pressure is exerted, with the filtered water, against a second side of the diaphragm. The second pressure is eliminated on the second side of the diaphragm such that the filtered water flows away from the diaphragm at the first pressure exerted against the first side of the diaphragm.

  • Adaptive refrigerator defrost method and apparatus
    Patent number: 6631620
    Abstract: A method and apparatus for defrosting an evaporator of a refrigeration system including a defrost heater and a controller operatively connected to the evaporator and a defrost heater is provided. The method comprises initiating a defrost cycle to energize the defrost heater to defrost the evaporator, monitoring a temperature of the evaporator, terminating the defrost cycle by de-energizing the defrost heater when a low temperature termination point of the evaporator is reached when in a low temperature defrost cycle, and terminating the defrost cycle by de-energizing the defrost heater when a high temperature termination point of the evaporator is reached when in a high temperature defrost cycle.
