Abstract: An interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

Abstract: A vaporizer for vaporizing liquid fuels having improved heat transfer and controls for vaporization of liquid fuels in response to varying degrees of fuel vapor demand and temperature requirements having a heat exchanger formed from multiple chambers having opposing surfaces composed of inert material at least at said surfaces with small but effective passages formed therebetween and the opposing surfaces being in small but effective passage relationship for sufficient length for the surface tension between a liquid fuel and the opposing surfaces of said multiple chambers to spread the liquid fuel over the opposing surfaces of the multiple chambers for maintaining said liquid fuel in relatively constant and thin liquid relationship to the opposing surfaces of the multiple chambers of the heat exchanger until the liquid fuel is vaporized; a delivery system for delivering liquid fuel to the heat exchanger; a heat delivery system for delivering heat and a heat exchanger for vaporizing the liquid fuel therein and

Abstract: A desiccant container is removably connected to the vent line of a fuel tank of a boat or the like to prevent accumulation of moisture in the fuel tank.

Abstract: A Solar Heater for collecting solar radiation in a fluid having a base, a flexible fluid retaining member connected adjacent the base for retaining a fluid, and for collecting the radiation of the sun, expansion limiting members connected to the base and positioned with respect to the flexible fluid retaining members for limiting the expansion of the flexible fluid collecting member, as a fluid is flowed through said flexible fluid retaining members by introducing the fluid through a flow way for flowing the fluid therein and a flow way for flowing the fluid therefrom.

Abstract: A fuel system adapted for use as the primary fuel source with a conventionally fueled and spark ignited internal combustion engine having a fuel tank for the primary fuel, a fuel pump for the primary fuel for pumping the primary fuel out of the fuel tank; a primary fuel vaporizer connected in communication with the pump and in heat conductive communication with a heat source for vaporizing the primary fuel, a vapor regulator means in vapor communication with the fuel vaporizer and the internal combustion engine for supplying fuel in varying amounts in response to varying conditions of demand on the engine and means connected to the system for sensing the conditions in the system and for switching said conventional fuel supply off and said primary fuel on when the conditions are sufficient for said primary fuel to operate the engine.

Abstract: A liquid aquifer energy storage method by which hot water is collected and stored in underground aquifers during the summer months and made available for heating during winter months. The liquid aquifer energy storage method also allows for the storage of cold water during the winter months for use in cooling during the summer months. The liquid aquifer energy storage method includes heating water and hot and warm zones within the aquifer or aquifers for storage of hot and warm water, respectively. Additionally, the method includes cooling water and cold and cool zones in the aquifer or aquifers for storage of cold and cool water.
