Abstract:
1. A submersible hand warmer apparatus, said apparatus comprising: a sleeve having a center sleeve portion with an elongate chamber having a right access port and a left access port, said chamber sized to accommodate an effective amount of a heat transfer fluid, where an effective amount is the amount that raises the temperature of the diver's hands to at least 54° F. (12° C.) upon immersion of his hands in the heat transfer fluid; said sleeve also having a right sleeve portion extending from the right access port with a right elastic cuff; and a left sleeve portion extending from the left access port with a left elastic cuff, where the right elastic cuff and the left elastic cuff stretch allowing the diver's gloved hands access to the chamber, and then the cuffs retract, forming at least a partial seal against a diver's right arm and left arm; a heating component which is in contact with the heat transfer fluid and warms the heat transfer fluid to at least 54° F.; an energy source that can provide sufficient energy to the heating component to heat the heat transfer fluid to at least 54° F.; a housing which provides structural support for the apparatus; an insulation that slows the loss of heat to cold ambient water; and a controller that controls a rate of energy received by the heating component, and therein the temperature of the heat transfer fluid.
