Abstract: An anti-exposure inflatable structure for reducing loss of heat from the body of a wearer, having spaced inflatable cavities with water vapor openings between cavities and an outer covering of a breathable, water-proof material loosely covering the outer surface of the structure, the structure having sealing means at its marginal edges to prevent water from entering between the body of a wearer and the structure.

Abstract: This invention discloses an apparatus for coupling and controlling the overall operation of the operable components of a heat pump system. All of the components of the system are coupled through a single master switching relay which provides a central location from which all of the operations of the system can be initiated and tested. Time delay relays are provided to stagger the start of the secondary heating units of the system to avoid an electrical power surge.

Abstract: This invention discloses a method and apparatus for coupling and controlling the operable components of a heat pump system to effectively regulate the temperature within a controlled environment. The operable components of the heat pump system include an indoor thermostat for monitoring the temperature within the controlled environment, an outdoor heat pump for heating and cooling the controlled environment, and an indoor fossil fuel furnace for supplementing the heating capacity of the heat pump. These components are operably coupled through a master switching relay which is arranged to use the monitored temperature of the controlled environment to select the operating mode of the system thereby providing an economical and efficient central control point.
