  • Continuous resistance and proximity checking for high power deicing and defogging systems
    Patent number: 11229091
    Abstract: A safety method and system consisting of resistance checking for use with high power deicing and defogging systems, including high power deicing and defogging systems for windshields and including quasi-continuous checking with pulse-electro thermal deicing and defogging systems, is disclosed. The resistance checking system may be combined with a proximity detector safety system which operates in conjunction with the resistance based safety system.
    Type: Grant

  • INSULATING SEPARATORS FOR SELF-DEFROSTING EVAPORATOR COIL OPTIMIZED FOR FROST-FREE AND FROST-LOADED CONDITIONS
    Publication number: 20180172333
    Abstract: Described herein is an evaporator and evaporator system. The system comprises a refrigerant tube formed from an electrically conductive material, the refrigerant tube being shaped to comprise a plurality of parallel tube portions; an upstream refrigerant conduit for supplying a refrigerant to the refrigerant tube; a downstream refrigerant conduit for receiving the refrigerant from the refrigerant tube; and a plurality of separators for securing the plurality of parallel tube portions in a plurality of relative positions to provide a plurality of airflow gaps separating adjacent parallel tube portions, and to impede electrical contact between different tube portions in the plurality of parallel tube portions.
