Abstract: A portable space heater includes a housing with an air inlet through which ambient air is received and an air vent through which heated air is expelled. A centrifugal fan of the heater is configured to drive air flow into the air inlet. A flow channel of the heater is configured to direct the air flow toward the air vent and a heating element heats the air flow in the flow channel. The heater additionally includes a sensor configured to sense proximity of a body part to the air vent and a controller configured to pause operation of the heating element based on the sensing, wherein the centrifugal fan, the flow channel, the heating element, the sensor and the controller are housed in the housing.

Abstract: A beverage cooling arrangement having an inner receptacle defined by a closed end, an open end and a wall disposed between the open and closed ends. An outer encasement partially encases the inner receptacle, and the encasement is joined at the upper end to the inner receptacle along the open end thereof forming a cavity between the inner receptacle and the encasement. A layer of cellular compressible heat-insulating material is disposed within the cavity adjacent the encasement. A solid gel refrigerant is disposed within the remainder of the cavity between the insulation layer and the receptacle. A base is secured to the outer encasement so as to completely seal and isolate the cavity from the outside environment.
